On the developer's end, this also represents a -fundamental disruption in the standard workflow of changes, commits, -and merges.

When a change is checked in, all modified files are grouped -into a logical unit, the changeset. Internally, BK links these -changesets in a tree, representing various converging and diverging -lines of development. These changesets are the bread and butter of -the BK system. - -After the concept of changesets, the next thing you need to get used -to is having multiple copies of source trees lying around. This -really- -takes some getting used to, for some people. Separate source trees -are the means in BitKeeper by which you delineate parallel lines -of development, both minor and major. What would be branches in -CVS become separate source trees, or "clones" in BitKeeper [heh, -or Star Wars] terminology. - -Clones and changesets are the tools from which most of the power of -BitKeeper is derived. As mentioned earlier, each clone has a parent, -the tree used as the source when the new clone was created. In a -CVS-like setup, the parent would be a remote server on the Internet, -and the child is your local clone of that tree. - -Once you have established a common baseline between two source trees -- -a common parent -- then you can merge changesets between those two -trees with ease. Merging changes into a tree is called a "pull", and -is analagous to 'cvs update'. A pull downloads all the changesets in -the remote tree you do not have, and merges them. Sending changes in -one tree to another tree is called a "push". Push sends all changes -in the local tree the remote does not yet have, and merges them. - -From these concepts come some initial command examples: - -1) bk clone -q http://linux.bkbits.net/linux-2.5 linus-2.5 -Download a 2.5 stock kernel tree, naming it "linus-2.5" in the local dir. -The "-q" disables listing every single file as it is downloaded. - -2) bk clone -ql linus-2.5 alpha-2.5 -Create a separate source tree for the Alpha AXP architecture. -The "-l" uses hard links instead of copying data, since both trees are -on the local disk. You can also replace the above with "bk lclone -q ..." - -You only clone a tree -once-. After cloning the tree lives a long time -on disk, being updating by pushes and pulls. - -3) cd alpha-2.5 ; bk pull http://gkernel.bkbits.net/alpha-2.5 -Download changes in "alpha-2.5" repository which are not present -in the local repository, and merge them into the source tree. - -4) bk -r co -q -Because every tree is a repository, files must be checked out before -they will be in their standard places in the source tree. - -5) bk vi fs/inode.c # example change... - bk citool # checkin, using X tool - bk push bk://gkernel@bkbits.net/alpha-2.5 # upload change -Typical example of a BK sequence that would replace the analagous CVS -situation, - vi fs/inode.c - cvs commit - -As this is just supposed to be a quick BK intro, for more in-depth -tutorials, live working demos, and docs, see http://www.bitkeeper.com/ - - - -BK and Kernel Development Workflow ----------------------------------- -Currently the latest 2.5 tree is available via "bk clone $URL" -and "bk pull $URL" at http://linux.bkbits.net/linux-2.5 -This should change in a few weeks to a kernel.org URL. - - -A big part of using BitKeeper is organizing the various trees you have -on your local disk, and organizing the flow of changes among those -trees, and remote trees. If one were to graph the relationships between -a desired BK setup, you are likely to see a few-many-few graph, like -this: - - linux-2.5 - | - merge-to-linus-2.5 - / | | - / | | - vm-hacks bugfixes filesys personal-hacks - \ | | / - \ | | / - \ | | / - testing-and-validation - -Since a "bk push" sends all changes not in the target tree, and -since a "bk pull" receives all changes not in the source tree, you want -to make sure you are only pushing specific changes to the desired tree, -not all changes from "peer parent" trees. For example, pushing a change -from the testing-and-validation tree would probably be a bad idea, -because it will push all changes from vm-hacks, bugfixes, filesys, and -personal-hacks trees into the target tree. - -One would typically work on only one "theme" at a time, either -vm-hacks or bugfixes or filesys, keeping those changes isolated in -their own tree during development, and only merge the isolated with -other changes when going upstream (to Linus or other maintainers) or -downstream (to your "union" trees, like testing-and-validation above). - -It should be noted that some of this separation is not just recommended -practice, it's actually [for now] -enforced- by BitKeeper. BitKeeper -requires that changesets maintain a certain order, which is the reason -that "bk push" sends all local changesets the remote doesn't have. This -separation may look like a lot of wasted disk space at first, but it -helps when two unrelated changes may "pollute" the same area of code, or -don't follow the same pace of development, or any other of the standard -reasons why one creates a development branch. - -Small development branches (clones) will appear and disappear: - - -------- A --------- B --------- C --------- D ------- - \ / - -----short-term devel branch----- - -While long-term branches will parallel a tree (or trees), with period -merge points. In this first example, we pull from a tree (pulls, -"\") periodically, such as what occurs when tracking changes in a -vendor tree, never pushing changes back up the line: - - -------- A --------- B --------- C --------- D ------- - \ \ \ - ----long-term devel branch----------------- - -And then a more common case in Linux kernel development, a long term -branch with periodic merges back into the tree (pushes, "/"): - - -------- A --------- B --------- C --------- D ------- - \ \ / \ - ----long-term devel branch----------------- - - - - - -Submitting Changes to Linus ---------------------------- -There's a bit of an art, or style, of submitting changes to Linus. -Since Linus's tree is now (you might say) fully integrated into the -distributed BitKeeper system, there are several prerequisites to -properly submitting a BitKeeper change. All these prereq's are just -general cleanliness of BK usage, so as people become experts at BK, feel -free to optimize this process further (assuming Linus agrees, of -course). - - - -0) Make sure your tree was originally cloned from the linux-2.5 tree -created by Linus. If your tree does not have this as its ancestor, it -is impossible to reliably exchange changesets. - - - -1) Pay attention to your commit text. The commit message that -accompanies each changeset you submit will live on forever in history, -and is used by Linus to accurately summarize the changes in each -pre-patch. Remember that there is no context, so - "fix for new scheduler changes" -would be too vague, but - "fix mips64 arch for new scheduler switch_to(), TIF_xxx semantics" -would be much better. - -You can and should use the command "bk comment -C" to update the -commit text, and improve it after the fact. This is very useful for -development: poor, quick descriptions during development, which get -cleaned up using "bk comment" before issuing the "bk push" to submit the -changes. - - - -2) Include an Internet-available URL for Linus to pull from, such as - - Pull from: http://gkernel.bkbits.net/net-drivers-2.5 - - - -3) Include a summary and "diffstat -p1" of each changeset that will be -downloaded, when Linus issues a "bk pull". The author auto-generates -these summaries using "bk changes -L ", to obtain a listing -of all the pending-to-send changesets, and their commit messages. - -It is important to show Linus what he will be downloading when he issues -a "bk pull", to reduce the time required to sift the changes once they -are downloaded to Linus's local machine. - -IMPORTANT NOTE: One of the features of BK is that your repository does -not have to be up to date, in order for Linus to receive your changes. -It is considered a courtesy to keep your repository fairly recent, to -lessen any potential merge work Linus may need to do. - - -4) Split up your changes. Each maintainer<->Linus situation is likely -to be slightly different here, so take this just as general advice. The -author splits up changes according to "themes" when merging with Linus. -Simultaneous pushes from local development go to special trees which -exist solely to house changes "queued" for Linus. Example of the trees: - - net-drivers-2.5 -- on-going net driver maintenance - vm-2.5 -- VM-related changes - fs-2.5 -- filesystem-related changes - -Linus then has much more freedom for pulling changes. He could (for -example) issue a "bk pull" on vm-2.5 and fs-2.5 trees, to merge their -changes, but hold off net-drivers-2.5 because of a change that needs -more discussion. - -Other maintainers may find that a single linus-pull-from tree is -adequate for passing BK changesets to him. - - - -Frequently Answered Questions ------------------------------ -1) How do I change the e-mail address shown in the changelog? -A. When you run "bk citool" or "bk commit", set environment - variables BK_USER and BK_HOST to the desired username - and host/domain name. - - -2) How do I use tags / get a diff between two kernel versions? -A. Pass the tags Linus uses to 'bk export'. - -ChangeSets are in a forward-progressing order, so it's pretty easy -to get a snapshot starting and ending at any two points in time. -Linus puts tags on each release and pre-release, so you could use -these two examples: - - bk export -tpatch -hdu -rv2.5.4,v2.5.5 | less - # creates patch-2.5.5 essentially - bk export -tpatch -du -rv2.5.5-pre1,v2.5.5 | less - # changes from pre1 to final - -A tag is just an alias for a specific changeset... and since changesets -are ordered, a tag is thus a marker for a specific point in time (or -specific state of the tree). - - -3) Is there an easy way to generate One Big Patch versus mainline, - for my long-lived kernel branch? -A. Yes.

There are areas that are not gray at all: user -space is clearly not a derived work, while kernel patches clearly _are_ -derived works. - -But one gray area in particular is something like a driver that was -originally written for another operating system (ie clearly not a derived -work of Linux in origin). At exactly what point does it become a derived -work of the kernel (and thus fall under the GPL)? - -THAT is a gray area, and _that_ is the area where I personally believe -that some modules may be considered to not be derived works simply because -they weren't designed for Linux and don't depend on any special Linux -behaviour. - -Basically: - - anything that was written with Linux in mind (whether it then _also_ - works on other operating systems or not) is clearly partially a derived - work. - - anything that has knowledge of and plays with fundamental internal - Linux behaviour is clearly a derived work. If you need to muck around - with core code, you're derived, no question about it. - -Historically, there's been things like the original Andrew filesystem -module: a standard filesystem that really wasn't written for Linux in the -first place, and just implements a UNIX filesystem. Is that derived just -because it got ported to Linux that had a reasonably similar VFS interface -to what other UNIXes did? Personally, I didn't feel that I could make that -judgment call.

It has nothing to do with modules per se, except that non-modules -clearly are derived works (if they are so central to the kenrel that you -can't load them as a module, they are clearly derived works just by virtue -of being very intimate - and because the GPL expressly mentions linking). - -So being a module is not a sign of not being a derived work.

That is -> done by the end user, not the plug-in creator. - -I agree, but also disrespectfully disagree ;) - -It's an issue of what a "plug-in" is - is it a way for the program to -internally load more modules as it needs them, or is it _meant_ to be a -public, published interface. - -For example, the "system call" interface could be considered a "plug-in -interface", and running a user mode program under Linux could easily be -construed as running a "plug-in" for the Linux kernel. No? - -And there, I obviously absolutely agree with you 100%: the interface is -published, and it's _meant_ for external and independent users. It's an -interface that we go to great lengths to preserve as well as we can, and -it's an interface that is designed to be independent of kernel versions. - -But maybe somebody wrote his program with the intention to dynamically -load "actors" as they were needed, as a way to maintain a good modularity, -and to try to keep the problem spaces well-defined. In that case, the -"plug-in" may technically follow all the same rules as the system call -interface, even though the author doesn't intend it that way. - -So I think it's to a large degree a matter of intent, but it could -arguably also be considered a matter of stability and documentation (ie -"require recompilation of the plug-in between version changes" would tend -to imply that it's an internal interface, while "documented binary -compatibility across many releases" implies a more stable external -interface, and less of a derived work) - -Does that make sense to you? - -> I asked Richard to comment on several scenarios involving plug-ins -> explain whether or not they were in violation of the GPL.

I'd just like to finish off with a few -comments, just to clarify my personal stand: - - - I'm obviously not the only copyright holder of Linux, and I did so on - purpose for several reasons. One reason is just because I hate the - paperwork and other cr*p that goes along with copyright assignments. - - Another is that I don't much like copyright assignments at all: the - author is the author, and he may be bound by my requirement for GPL, - but that doesn't mean that he should give his copyright to me. - - A third reason, and the most relevant reason here, is that I want - people to _know_ that I cannot control the sources. I can write you a - note to say that "for use XXX, I do not consider module YYY to be a - derived work of my kernel", but that would not really matter that much. - Any other Linux copyright holder might still sue you. - - This third reason is what makes people who otherwise might not trust me - realize that I cannot screw people over. I am bound by the same - agreement that I require of everybody else, and the only special status - I really have is a totally non-legal issue: people trust me. - - (Yes, I realize that I probably would end up having more legal status - than most, even apart from the fact that I still am the largest single - copyright holder, if only because of appearances) - - - I don't really care about copyright law itself. What I care about is my - own morals. Whether I'd ever sue somebody or not (and quite frankly, - it's the last thing I ever want to do - if I never end up talking to - lawyers in a professional context, I'll be perfectly happy. No - disrespect intended) will be entirely up to whether I consider what - people do to me "moral" or not. Which is why intent matters to me a - lot - both the intent of the person/corporation doign the infringement, - _and_ the intent of me and others in issues like the module export - interface. - - Another way of putting this: I don't care about "legal loopholes" and - word-wrangling. - - - Finally: I don't trust the FSF. I like the GPL a lot - although not - necessarily as a legal piece of paper, but more as an intent. Which - explains why, if you've looked at the Linux COPYING file, you may have - noticed the explicit comment about "only _this_ particular version of - the GPL covers the kernel by default". - - That's because I agree with the GPL as-is, but I do not agree with the - FSF on many other matters. I don't like software patents much, for - example, but I do not want the code I write to be used as a weapon - against companies that have them. The FSF has long been discussing and - is drafting the "next generation" GPL, and they generally suggest that - people using the GPL should say "v2 or at your choice any later - version". - - Linux doesn't do that. The Linux kernel is v2 ONLY, apart from a few - files where the author put in the FSF extension (and see above about - copyright assignments why I would never remove such an extension). - -The "v2 only" issue might change some day, but only after all documented -copyright holders agree on it, and only after we've seen what the FSF -suggests. From what I've seen so far from the FSF drafts, we're not likely -to change our v2-only stance, but there might of course be legal reasons -why we'd have to do something like it (ie somebody challenging the GPLv2 -in court, and part of it to be found unenforceable or similar would -obviously mean that we'd have to reconsider the license). - - Linus - -PS. Historically, binary-only modules have not worked well under Linux, -quite regardless of any copyright issues. The kernel just develops too -quickly for binary modules to work well, and nobody really supports them. -Companies like Red Hat etc tend to refuse to have anything to do with -binary modules, because if something goes wrong there is nothing they can -do about it. So I just wanted to let you know that the _legal_ issue is -just the beginning. Even though you probably don't personally care ;) - - diff --git a/Documentation/DocBook/genericirq.tmpl b/Documentation/DocBook/genericirq.tmpl deleted file mode 100644 index 0f4a4b632..000000000 --- a/Documentation/DocBook/genericirq.tmpl +++ /dev/null @@ -1,474 +0,0 @@ - - - - - - Linux generic IRQ handling - - - - Thomas - Gleixner - -

Device drivers use generic API functions to request, enable, - disable and free interrupts. The drivers do not have to know anything - about interrupt hardware details, so they can be used on different - platforms without code changes. - - - This documentation is provided to developers who want to implement - an interrupt subsystem based for their architecture, with the help - of the generic IRQ handling layer. - - - - - Rationale - - The original implementation of interrupt handling in Linux is using - the __do_IRQ() super-handler, which is able to deal with every - type of interrupt logic. - - - Originally, Russell King identified different types of handlers to - build a quite universal set for the ARM interrupt handler - implementation in Linux 2.5/2.6. He distinguished between: - - Level type - Edge type - Simple type - - In the SMP world of the __do_IRQ() super-handler another type - was identified: - - Per CPU type - - - - This split implementation of highlevel IRQ handlers allows us to - optimize the flow of the interrupt handling for each specific - interrupt type. This reduces complexity in that particular codepath - and allows the optimized handling of a given type. - - - The original general IRQ implementation used hw_interrupt_type - structures and their ->ack(), ->end() [etc.] callbacks to - differentiate the flow control in the super-handler. This leads to - a mix of flow logic and lowlevel hardware logic, and it also leads - to unnecessary code duplication: for example in i386, there is a - ioapic_level_irq and a ioapic_edge_irq irq-type which share many - of the lowlevel details but have different flow handling. - - - A more natural abstraction is the clean separation of the - 'irq flow' and the 'chip details'. - - - Analysing a couple of architecture's IRQ subsystem implementations - reveals that most of them can use a generic set of 'irq flow' - methods and only need to add the chip level specific code. - The separation is also valuable for (sub)architectures - which need specific quirks in the irq flow itself but not in the - chip-details - and thus provides a more transparent IRQ subsystem - design. - - - Each interrupt descriptor is assigned its own highlevel flow - handler, which is normally one of the generic - implementations. (This highlevel flow handler implementation also - makes it simple to provide demultiplexing handlers which can be - found in embedded platforms on various architectures.) - - - The separation makes the generic interrupt handling layer more - flexible and extensible. For example, an (sub)architecture can - use a generic irq-flow implementation for 'level type' interrupts - and add a (sub)architecture specific 'edge type' implementation. - - - To make the transition to the new model easier and prevent the - breakage of existing implementations, the __do_IRQ() super-handler - is still available. This leads to a kind of duality for the time - being. Over time the new model should be used in more and more - architectures, as it enables smaller and cleaner IRQ subsystems. - - - - Known Bugs And Assumptions - - None (knock on wood). - - - - - Abstraction layers - - There are three main levels of abstraction in the interrupt code: - - Highlevel driver API - Highlevel IRQ flow handlers - Chiplevel hardware encapsulation - - - - Interrupt control flow - - Each interrupt is described by an interrupt descriptor structure - irq_desc. The interrupt is referenced by an 'unsigned int' numeric - value which selects the corresponding interrupt decription structure - in the descriptor structures array. - The descriptor structure contains status information and pointers - to the interrupt flow method and the interrupt chip structure - which are assigned to this interrupt. - - - Whenever an interrupt triggers, the lowlevel arch code calls into - the generic interrupt code by calling desc->handle_irq(). - This highlevel IRQ handling function only uses desc->chip primitives - referenced by the assigned chip descriptor structure. - - - - Highlevel Driver API - - The highlevel Driver API consists of following functions: - - request_irq() - free_irq() - disable_irq() - enable_irq() - disable_irq_nosync() (SMP only) - synchronize_irq() (SMP only) - set_irq_type() - set_irq_wake() - set_irq_data() - set_irq_chip() - set_irq_chip_data() - - See the autogenerated function documentation for details. - - - - Highlevel IRQ flow handlers - - The generic layer provides a set of pre-defined irq-flow methods: - - handle_level_irq - handle_edge_irq - handle_simple_irq - handle_percpu_irq - - The interrupt flow handlers (either predefined or architecture - specific) are assigned to specific interrupts by the architecture - either during bootup or during device initialization. - - - Default flow implementations - - Helper functions - - The helper functions call the chip primitives and - are used by the default flow implementations. - The following helper functions are implemented (simplified excerpt): - -default_enable(irq) -{ - desc->chip->unmask(irq); -} - -default_disable(irq) -{ - if (!delay_disable(irq)) - desc->chip->mask(irq); -} - -default_ack(irq) -{ - chip->ack(irq); -} - -default_mask_ack(irq) -{ - if (chip->mask_ack) { - chip->mask_ack(irq); - } else { - chip->mask(irq); - chip->ack(irq); - } -} - -noop(irq) -{ -} - - - - - - - Default flow handler implementations - - Default Level IRQ flow handler - - handle_level_irq provides a generic implementation - for level-triggered interrupts. - - - The following control flow is implemented (simplified excerpt): - -desc->chip->start(); -handle_IRQ_event(desc->action); -desc->chip->end(); - - - - - Default Edge IRQ flow handler - - handle_edge_irq provides a generic implementation - for edge-triggered interrupts. - - - The following control flow is implemented (simplified excerpt): - -if (desc->status & running) { - desc->chip->hold(); - desc->status |= pending | masked; - return; -} -desc->chip->start(); -desc->status |= running; -do { - if (desc->status & masked) - desc->chip->enable(); - desc-status &= ~pending; - handle_IRQ_event(desc->action); -} while (status & pending); -desc-status &= ~running; -desc->chip->end(); - - - - - Default simple IRQ flow handler - - handle_simple_irq provides a generic implementation - for simple interrupts. - - - Note: The simple flow handler does not call any - handler/chip primitives. - - - The following control flow is implemented (simplified excerpt): - -handle_IRQ_event(desc->action); - - - - - Default per CPU flow handler - - handle_percpu_irq provides a generic implementation - for per CPU interrupts. - - - Per CPU interrupts are only available on SMP and - the handler provides a simplified version without - locking. - - - The following control flow is implemented (simplified excerpt): - -desc->chip->start(); -handle_IRQ_event(desc->action); -desc->chip->end(); - - - - - - Quirks and optimizations - - The generic functions are intended for 'clean' architectures and chips, - which have no platform-specific IRQ handling quirks. If an architecture - needs to implement quirks on the 'flow' level then it can do so by - overriding the highlevel irq-flow handler. - - - - Delayed interrupt disable - - This per interrupt selectable feature, which was introduced by Russell - King in the ARM interrupt implementation, does not mask an interrupt - at the hardware level when disable_irq() is called. The interrupt is - kept enabled and is masked in the flow handler when an interrupt event - happens. This prevents losing edge interrupts on hardware which does - not store an edge interrupt event while the interrupt is disabled at - the hardware level. When an interrupt arrives while the IRQ_DISABLED - flag is set, then the interrupt is masked at the hardware level and - the IRQ_PENDING bit is set. When the interrupt is re-enabled by - enable_irq() the pending bit is checked and if it is set, the - interrupt is resent either via hardware or by a software resend - mechanism. (It's necessary to enable CONFIG_HARDIRQS_SW_RESEND when - you want to use the delayed interrupt disable feature and your - hardware is not capable of retriggering an interrupt.) - The delayed interrupt disable can be runtime enabled, per interrupt, - by setting the IRQ_DELAYED_DISABLE flag in the irq_desc status field. - - - - - Chiplevel hardware encapsulation - - The chip level hardware descriptor structure irq_chip - contains all the direct chip relevant functions, which - can be utilized by the irq flow implementations. - - ack() - mask_ack() - Optional, recommended for performance - mask() - unmask() - retrigger() - Optional - set_type() - Optional - set_wake() - Optional - - These primitives are strictly intended to mean what they say: ack means - ACK, masking means masking of an IRQ line, etc. It is up to the flow - handler(s) to use these basic units of lowlevel functionality. - - - - - - __do_IRQ entry point - - The original implementation __do_IRQ() is an alternative entry - point for all types of interrupts. - - - This handler turned out to be not suitable for all - interrupt hardware and was therefore reimplemented with split - functionality for egde/level/simple/percpu interrupts.

Not all mice are handled by the kernel. - Instead there is a two layer abstraction. - - - - The kernel mouse drivers and userspace drivers for the serial mice are - all managed by a system daemon called gpm - - the general purpose mouse driver. gpm - handles cutting and pasting on the text consoles. It provides a - general library for mouse-aware applications and it handles the - sharing of mouse services with the - X Window System user interface. - - - Sometimes a mouse speaks a sufficiently convoluted protocol that the - protocol is handled by Gpm itself. Most - of the mouse drivers follow a common interface called the bus mouse - protocol. - - - Each read from a bus mouse interface device returns a block of data. - The first three bytes of each read are defined as follows: - - - Mouse Data Encoding - - - - Byte 0 - 0x80 + the buttons currently down. - - - Byte 1 - A signed value for the shift in X position - - - Byte 2 - A signed value for the shift in Y position - - - -
- - An application can choose to read more than 3 bytes. The rest of the - bytes will be zero, or may optionally return some additional - device-specific information. - - - The position values are truncated if they exceed the 8bit range (that - is -127 <= delta <= 127). While the value -128 does fit into a - byte is not allowed. - - - The buttons are numbered left to right as - 0, 1, 2, 3.. and each button sets the relevant bit. So a user pressing - the left and right button of a three button mouse will set bits 0 and 2. - - - All mice are required to support the poll - operation. Indeed pretty much every user of a mouse device uses - poll to wait for mouse events to occur. - - - Finally the mice support asynchronous I/O. This is a topic we have not - yet covered but which I will explain after looking at a simple mouse - driver. - - - - - A simple mouse driver - - First we will need the set up functions for our mouse device. To keep - this simple our imaginary mouse device has three I/O ports fixed at I/O - address 0x300 and always lives on interrupt 5. The ports will be the X - position, the Y position and the buttons in that order. - - - -#define OURMOUSE_BASE 0x300 - -static struct miscdevice our_mouse = { - OURMOUSE_MINOR, "ourmouse", &our_mouse_fops -}; - -__init ourmouse_init(void) -{ - - if (request_region(OURMOUSE_BASE, 3, "ourmouse") < 0) { - printk(KERN_ERR "ourmouse: request_region failed.\n"); - return -ENODEV; - } - - if (misc_register(&our_mouse) < 0) { - printk(KERN_ERR "ourmouse: cannot register misc device.\n"); - release_region(OURMOUSE_BASE, 3); - return -EBUSY; - } - - return 0; -} - - - - The miscdevice is new here. Linux normally - parcels devices out by major number, and each device has 256 units. - For things like mice this is extremely wasteful so a device exists - which is used to accumulate all the odd individual devices that - computers tend to have. - - - Minor numbers in this space are allocated by a central source, although - you can look in the kernel Documentation/devices.txt - file and pick a free one for development use. This kernel file also - carries instructions for registering a device. This may change over time - so it is a good idea to obtain a current copy of this file first. - - - Our code then is fairly simple. We reserve our I/O address space with - request_region, checking to make sure that it succeeded (i.e. the - space wasn't reserved by anyone else). - - - Then we ask the misc driver to allocate our minor device number. We also - hand it our name (which is used in - /proc/misc) and a set of file - operations that are to be used. The file operations work exactly like the - file operations you would register for a normal character device. The misc - device itself is simply acting as a redirector for requests. - Since misc_register can fail, it is important to check for failure - and act accordingly (which in the case of a mouse driver is to abort, - since you can't use the mouse without a working device node). - - - Next, in order to be able to use and test our code we need to add some - module code to support it. This too is fairly simple: - - -#ifdef MODULE - -int init_module(void) -{ - if(ourmouse_init()<0) - return -ENODEV: - return 0; -} - -void cleanup_module(void) -{ - misc_deregister(&our_mouse); - free_region(OURMOUSE_BASE, 3); -} - - -#endif - - - - The module code provides the normal two functions. The - init_module function is called when the module is - loaded. In our case it simply calls the initialising function we wrote - and returns an error if this fails. This ensures the module will only - be loaded if it was successfully set up. - - - The cleanup_module function is called when the - module is unloaded. We give the miscellaneous device entry back, and - then free our I/O resources. If we didn't free the I/O resources then - the next time the module loaded it would think someone else had its I/O - space. - - - Once the misc_deregister has been called any - attempts to open the mouse device will fail with the error - ENODEV (No such device). - - - Next we need to fill in our file operations. A mouse doesn't need many - of these. We need to provide open, release, read and poll. That makes - for a nice simple structure: - - - -struct file_operations our_mouse_fops = { - owner: THIS_MODULE, /* Automatic usage management */ - read: read_mouse, /* You can read a mouse */ - write: write_mouse, /* This won't do a lot */ - poll: poll_mouse, /* Poll */ - open: open_mouse, /* Called on open */ - release: close_mouse, /* Called on close */ -}; - - - - There is nothing particularly special needed here. We provide functions - for all the relevant or required operations and little else. There is - nothing stopping us providing an ioctl function for this mouse. Indeed - if you have a configurable mouse it may be very appropriate to provide - configuration interfaces via ioctl calls. - - - The syntax we use is not standard C as such. GCC provides the ability - to initialise fields by name, and this generally makes the method table - much easier to read than counting through NULL pointers and remembering - the order by hand. - - - The owner field is used to manage the locking of module load an - unloading. It is obviously important that a module is not unloaded while - in use. When your device is opened the module specified by "owner" is - locked. When it is finally released the module is unlocked. - - - The open and close routines need to manage enabling and disabling the - interrupts for the mouse as well as stopping the mouse being unloaded - when it is no longer required. - - - -static int mouse_users = 0; /* User count */ -static int mouse_dx = 0; /* Position changes */ -static int mouse_dy = 0; -static int mouse_event = 0; /* Mouse has moved */ - -static int open_mouse(struct inode *inode, struct file *file) -{ - if(mouse_users++) - return 0; - - if(request_irq(mouse_intr, OURMOUSE_IRQ, 0, "ourmouse", NULL)) - { - mouse_users--; - return -EBUSY; - } - mouse_dx = 0; - mouse_dy = 0; - mouse_event = 0; - mouse_buttons = 0; - return 0; -} - - - The open function has to do a small amount of housework. We keep a count - of the number of times the mouse is open. This is because we do not want - to request the interrupt multiple times. If the mouse has at least one - user then it is set up and we simply add to the user count and return - 0 for success. - - - We grab the interrupt and thus start mouse interrupts. If the interrupt - has been borrowed by some other driver then request_irq - will fail and we will return an error. If we were capable of sharing an - interrupt line we would specify SA_SHIRQ instead of - zero. Provided that everyone claiming an interrupt - sets this flag, they get to share the line. PCI can - share interrupts, ISA normally however cannot. - - - We do the housekeeping. We make the current mouse position the starting - point for accumulated changes and declare that nothing has happened - since the mouse driver was opened. - - - The release function needs to unwind all these: - - -static int close_mouse(struct inode *inode, struct file *file) -{ - if(--mouse_users) - return 0; - free_irq(OURMOUSE_IRQ, NULL); - return 0; -} - - - We count off a user and provided that there are still other users need - take no further action. The last person closing the mouse causes us to - free up the interrupt. This stops interrupts from the mouse from using - our CPU time, and ensures that the mouse can now be unloaded. - - - We can fill in the write handler at this point as the write function for - our mouse simply declines to allow writes: - - - -static ssize_t write_mouse(struct file *file, const char *buffer, size_t - count, loff_t *ppos) -{ - return -EINVAL; -} - - - - This is pretty much self-explanatory. Whenever you write you get told - it was an invalid function. - - - To make the poll and read functions work we have to consider how we - handle the mouse interrupt. - - - -static struct wait_queue *mouse_wait; -static spinlock_t mouse_lock = SPIN_LOCK_UNLOCKED; - -static void ourmouse_interrupt(int irq, void *dev_id, struct pt_regs *regs) -{ - char delta_x; - char delta_y; - unsigned char new_buttons; - - delta_x = inb(OURMOUSE_BASE); - delta_y = inb(OURMOUSE_BASE+1); - new_buttons = inb(OURMOUSE_BASE+2); - - if(delta_x || delta_y || new_buttons != mouse_buttons) - { - /* Something happened */ - - spin_lock(&mouse_lock); - mouse_event = 1; - mouse_dx += delta_x; - mouse_dy += delta_y; - mouse_buttons = new_buttons; - spin_unlock(&mouse_lock); - - wake_up_interruptible(&mouse_wait); - } -} - - - - The interrupt handler reads the mouse status. The next thing we do is - to check whether something has changed. If the mouse was smart it would - only interrupt us if something had changed, but let's assume our mouse - is stupid as most mice actually tend to be. - - - If the mouse has changed we need to update the status variables. What we - don't want is the mouse functions reading these variables to read them - during a change. We add a spinlock that protects these variables while we - play with them. - - - If a change has occurred we also need to wake sleeping processes, so we - add a wakeup call and a wait_queue to use when - we wish to await a mouse event. - - - Now we have the wait queue we can implement the poll function for the - mouse relatively easily: - - - -static unsigned int mouse_poll(struct file *file, poll_table *wait) -{ - poll_wait(file, &mouse_wait, wait); - if(mouse_event) - return POLLIN | POLLRDNORM; - return 0; -} - - - - This is fairly standard poll code. First we add the wait queue to the - list of queues we want to monitor for an event. Secondly we check if an - event has occurred. We only have one kind of event - the - mouse_event flag tells us that something happened. - We know that this something can only be mouse data. We return the flags - indicating input and normal reading will succeed. - - - You may be wondering what happens if the function returns saying 'no - event yet'. In this case the wake up from the wait queue we added to - the poll table will cause the function to be called again. Eventually - we will be woken up and have an event ready. At this point the - poll call will exit back to the user. - - - After the poll completes the user will want to read the data. We now - need to think about how our mouse_read function - will work: - - -static ssize_t mouse_read(struct file *file, char *buffer, - size_t count, loff_t *pos) -{ - int dx, dy; - unsigned char button; - unsigned long flags; - int n; - - if(count<3) - return -EINVAL; - - /* - * Wait for an event - */ - - while(!mouse_event) - { - if(file->f_flags&O_NDELAY) - return -EAGAIN; - interruptible_sleep_on(&mouse_wait); - if(signal_pending(current)) - return -ERESTARTSYS; - } - - - - We start by validating that the user is reading enough data. We could - handle partial reads if we wanted but it isn't terribly useful and the - mouse drivers don't bother to try. - - - Next we wait for an event to occur. The loop is fairly standard event - waiting in Linux. Having checked that the event has not yet occurred, we - then check if an event is pending and if not we need to sleep. - - - A user process can set the O_NDELAY flag on a file - to indicate that it wishes to be told immediately if no event is - pending. We check this and give the appropriate error if so. - - - Next we sleep until the mouse or a signal awakens us. A signal will - awaken us as we have used wakeup_interruptible. - This is important as it means a user can kill processes waiting for - the mouse - clearly a desirable property. If we are interrupted we - exit the call and the kernel will then process signals and maybe - restart the call again - from the beginning. - - - This code contains a classic Linux bug. All will be revealed later in this - article as well as explanations for how to avoid it. - - - /* Grab the event */ - - spinlock_irqsave(&mouse_lock, flags); - - dx = mouse_dx; - dy = mouse_dy; - button = mouse_buttons; - - if(dx<=-127) - dx=-127; - if(dx>=127) - dx=127; - if(dy<=-127) - dy=-127; - if(dy>=127) - dy=127; - - mouse_dx -= dx; - mouse_dy -= dy; - - if(mouse_dx == 0 && mouse_dy == 0) - mouse_event = 0; - - spin_unlock_irqrestore(&mouse_lock, flags); - - - This is the next stage. Having established that there is an event - going, we capture it. To be sure that the event is not being updated - as we capture it we also take the spinlock and thus prevent parallel - updates. Note here we use spinlock_irqsave. We - need to disable interrupts on the local processor otherwise bad things - will happen. - - - What will occur is that we take the spinlock. While we hold the lock - an interrupt will occur. At this point our interrupt handler will try - and take the spinlock. It will sit in a loop waiting for the read - routine to release the lock. However because we are sitting in a loop - in the interrupt handler we will never release the lock. The machine - hangs and the user gets upset. - - - By blocking the interrupt on this processor we ensure that the lock - holder will always give the lock back without deadlocking. - - - There is a little cleverness in the reporting mechanism too. We can - only report a move of 127 per read. We don't however want to lose - information by throwing away further movement. Instead we keep - returning as much information as possible. Each time we return a - report we remove the amount from the pending movement in - mouse_dx and mouse_dy. Eventually - when these counts hit zero we clear the mouse_event - flag as there is nothing else left to report. - - - - if(put_user(button|0x80, buffer)) - return -EFAULT; - if(put_user((char)dx, buffer+1)) - return -EFAULT; - if(put_user((char)dy, buffer+2)) - return -EFAULT; - - for(n=3; n < count; n++) - if(put_user(0x00, buffer+n)) - return -EFAULT; - - return count; -} - - - - Finally we must put the results in the user supplied buffer. We cannot - do this while holding the lock as a write to user memory may sleep. - For example the user memory may be residing on disk at this instant. - Thus we did our computation beforehand and now copy the data. Each - put_user call is filling in one byte of the buffer. - If it returns an error we inform the program that it passed us an - invalid buffer and abort. - - - Having written the data we blank the rest of the buffer that was read - and report the read as being successful. - - - - - Debugging the mouse driver - - - We now have an almost perfectly usable mouse driver. If you were to - actually try and use it however you would eventually find a couple of - problems with it. A few programs will also not work with as it does not - yet support asynchronous I/O. - - - First let us look at the bugs. The most obvious one isn't really a driver - bug but a failure to consider the consequences. Imagine you bumped the - mouse hard by accident and sent it skittering across the desk. The mouse - interrupt routine will add up all that movement and report it in steps of - 127 until it has reported all of it. Clearly there is a point beyond - which mouse movement isn't worth reporting. We need to add this as a - limit to the interrupt handler: - - - -static void ourmouse_interrupt(int irq, void *dev_id, struct pt_regs *regs) -{ - char delta_x; - char delta_y; - unsigned char new_buttons; - - delta_x = inb(OURMOUSE_BASE); - delta_y = inb(OURMOUSE_BASE+1); - new_buttons = inb(OURMOUSE_BASE+2); - - if(delta_x || delta_y || new_buttons != mouse_buttons) - { - /* Something happened */ - - spin_lock(&mouse_lock); - mouse_event = 1; - mouse_dx += delta_x; - mouse_dy += delta_y; - - if(mouse_dx < -4096) - mouse_dx = -4096; - if(mouse_dx > 4096) - mouse_dx = 4096; - - if(mouse_dy < -4096) - mouse_dy = -4096; - if(mouse_dy > 4096) - mouse_dy = 4096; - - mouse_buttons = new_buttons; - spin_unlock(&mouse_lock); - - wake_up_interruptible(&mouse_wait); - } -} - - - - By adding these checks we limit the range of accumulated movement to - something sensible. - - - The second bug is a bit more subtle, and that is perhaps why this is - such a common mistake. Remember, I said the waiting loop for the read - handler had a bug in it. Think about what happens when we execute: - - - - while(!mouse_event) - { - - - - and an interrupt occurs at this point here. This causes a mouse movement - and wakes up the queue. - - - - interruptible_sleep_on(&mouse_wait); - - - - Now we sleep on the queue. We missed the wake up and the application - will not see an event until the next mouse event occurs. This will - lead to just the odd instance when a mouse button gets delayed. The - consequences to the user will probably be almost undetectable with a - mouse driver. With other drivers this bug could be a lot more severe. - - - There are two ways to solve this. The first is to disable interrupts - during the testing and the sleep. This works because when a task sleeps - it ceases to disable interrupts, and when it resumes it disables them - again. Our code thus becomes: - - - - save_flags(flags); - cli(); - - while(!mouse_event) - { - if(file->f_flags&O_NDELAY) - { - restore_flags(flags); - return -EAGAIN; - } - interruptible_sleep_on(&mouse_wait); - if(signal_pending(current)) - { - restore_flags(flags); - return -ERESTARTSYS; - } - } - restore_flags(flags); - - - - This is the sledgehammer approach. It works but it means we spend a - lot more time turning interrupts on and off. It also affects - interrupts globally and has bad properties on multiprocessor machines - where turning interrupts off globally is not a simple operation, but - instead involves kicking each processor, waiting for them to disable - interrupts and reply. - - - The real problem is the race between the event testing and the sleeping. - We can avoid that by using the scheduling functions more directly. - Indeed this is the way they generally should be used for an interrupt. - - - - struct wait_queue wait = { current, NULL }; - - add_wait_queue(&mouse_wait, &wait); - set_current_state(TASK_INTERRUPTIBLE); - - while(!mouse_event) - { - if(file->f_flags&O_NDELAY) - { - remove_wait_queue(&mouse_wait, &wait); - set_current_state(TASK_RUNNING); - return -EWOULDBLOCK; - } - if(signal_pending(current)) - { - remove_wait_queue(&mouse_wait, &wait); - current->state = TASK_RUNNING; - return -ERESTARTSYS; - } - schedule(); - set_current_state(TASK_INTERRUPTIBLE); - } - - remove_wait_wait(&mouse_wait, &wait); - set_current_state(TASK_RUNNING); - - - - At first sight this probably looks like deep magic. To understand how - this works you need to understand how scheduling and events work on - Linux. Having a good grasp of this is one of the keys to writing clean - efficient device drivers. - - - add_wait_queue does what its name suggests. It adds - an entry to the mouse_wait list. The entry in this - case is the entry for our current process (current - is the current task pointer). - - - So we start by adding an entry for ourself onto the - mouse_wait list. This does not put us to sleep - however. We are merely tagged onto the list. - - - Next we set our status to TASK_INTERRUPTIBLE. Again - this does not mean we are now asleep. This flag says what should happen - next time the process sleeps. TASK_INTERRUPTIBLE says - that the process should not be rescheduled. It will run from now until it - sleeps and then will need to be woken up. - - - The wakeup_interruptible call in the interrupt - handler can now be explained in more detail. This function is also very - simple. It goes along the list of processes on the queue it is given and - any that are marked as TASK_INTERRUPTIBLE it changes - to TASK_RUNNING and tells the kernel that new - processes are runnable. - - - Behind all the wrappers in the original code what is happening is this - - - - - - We add ourself to the mouse wait queue - - - - - We mark ourself as sleeping - - - - - We ask the kernel to schedule tasks again - - - - - The kernel sees we are asleep and schedules someone else. - - - - - The mouse interrupt sets our state to TASK_RUNNING - and makes a note that the kernel should reschedule tasks - - - - - The kernel sees we are running again and continues our execution - - - - - This is why the apparent magic works. Because we mark ourself as - TASK_INTERRUPTIBLE and as we add ourselves - to the queue before we check if there are events pending, the race - condition is removed. - - - Now if an interrupt occurs after we check the queue status and before - we call the schedule function in order to sleep, - things work out. Instead of missing an event, we are set back to - TASK_RUNNING by the mouse interrupt. We still call - schedule but it will continue running our task. - We go back around the loop and this time there may be an event. - - - There will not always be an event. Thus we set ourselves back to - TASK_INTERRUPTIBLE before resuming the loop. - Another process doing a read may already have cleared the event flag, - and if so we will need to go back to sleep again. Eventually we will - get our event and escape. - - - Finally when we exit the loop we remove ourselves from the - mouse_wait queue as we are no longer interested - in mouse events, and we set ourself back to - TASK_RUNNABLE as we do not wish to go to sleep - again just yet. - - - Note - - This isn't an easy topic. Don't be afraid to reread the description a - few times and also look at other device drivers to see how it works. - Finally if you can't grasp it just yet, you can use the code as - boilerplate to write other drivers and trust me instead. - - - - - - Asynchronous I/O - - This leaves the missing feature - Asynchronous I/O. Normally UNIX - programs use the poll call (or its variant form - select) to wait for an event to occur on one of - multiple input or output devices. This model works well for most tasks - but because poll and select - wait for an event isn't suitable for tasks that are also continually - doing computation work. Such programs really want the kernel to kick - them when something happens rather than watch for events. - - - Poll is akin to having a row of lights in front of you. You can see at a - glance which ones if any are lit. You cannot however get anything useful - done while watching them. Asynchronous I/O uses signals which work more - like a door bell. Instead of you watching, it tells you that something - is up. - - - Asynchronous I/O sends the signal SIGIO to a user process when the I/O - events occur. In this case that means when people move the mouse. The - SIGIO signal causes the user process to jump to its signal handler and - execute code in that handler before returning to whatever was going on - previously. It is the application equivalent of an interrupt handler. - - - Most of the code needed for this operation is common to all its users. - The kernel provides a simple set of functions for managing asynchronous - I/O. - - - Our first job is to allow users to set asynchronous I/O on file handles. - To do that we need to add a new function to the file operations table for - our mouse: - - - -struct file_operations our_mouse_fops = { - owner: THIS_MODULE - read: read_mouse, /* You can read a mouse */ - write: write_mouse, /* This won't do a lot */ - poll: poll_mouse, /* Poll */ - open: open_mouse, /* Called on open */ - release: close_mouse, /* Called on close */ - fasync: fasync_mouse, /* Asynchronous I/O */ -}; - - - - Once we have installed this entry the kernel knows we support - asynchronous I/O and will allow all the relevant operations on the - device. Whenever a user adds or removes asynchronous I/O notification - on a file handle it calls our fasync_mouse routine - we just added. This routine uses the helper functions to keep the queue - of handles up to date: - - - -static struct fasync_struct *mouse_fasync = NULL; - -static int fasync_mouse(int fd, struct file *filp, int on) -{ - int retval = fasync_helper(fd, filp, on, &mouse_fasync); - - if (retval < 0) - return retval; - return 0; -} - - - - The fasync helper adds and deletes entries by managing the supplied - list. We also need to remove entries from this list when the file is - closed. This requires we add one line to our close function: - - - -static int close_mouse(struct inode *inode, struct file *file) -{ - fasync_mouse(-1, file, 0) - if(--mouse_users) - return 0; - free_irq(OURMOUSE_IRQ, NULL); - return 0; -} - - - - When we close the file we now call our own fasync handler as if the - user had requested that this file cease to be used for asynchronous - I/O. This rather neatly cleans up any loose ends. We certainly don't - wait to deliver a signal for a file that no longer exists. - - - At this point the mouse driver supports all the asynchronous I/O - operations, and applications using them will not error. They won't - however work yet. We need to actually send the signals. Again the - kernel provides a function for handling this. - - - We update our interrupt handler a little: - - - -static void ourmouse_interrupt(int irq, void *dev_id, struct pt_regs *regs) -{ - char delta_x; - char delta_y; - unsigned char new_buttons; - - delta_x = inb(OURMOUSE_BASE); - delta_y = inb(OURMOUSE_BASE+1); - new_buttons = inb(OURMOUSE_BASE+2); - - if(delta_x || delta_y || new_buttons != mouse_buttons) - { - /* Something happened */ - - spin_lock(&mouse_lock); - mouse_event = 1; - mouse_dx += delta_x; - mouse_dy += delta_y; - - if(mouse_dx < -4096) - mouse_dx = -4096; - if(mouse_dx > 4096) - mouse_dx = 4096; - - if(mouse_dy < -4096) - mouse_dy = -4096; - if(mouse_dy > 4096) - mouse_dy = 4096; - - mouse_buttons = new_buttons; - spin_unlock(&mouse_lock); - - /* Now we do asynchronous I/O */ - kill_fasync(&mouse_fasync, SIGIO); - - wake_up_interruptible(&mouse_wait); - } -} - - - - The new code simply calls the kill_fasync routine - provided by the kernel if the queue is non-empty. This sends the - required signal (SIGIO in this case) to the process each file handle - says should be informed about the exciting new mouse movement that - just happened. - - - With this in place and the bugs in the original version fixed, you now - have a fully functional mouse driver using the bus mouse protocol. It - will work with the X window system, will work - with GPM and should work with every other - application you need. Doom is of course the - ideal way to test your new mouse driver is functioning properly.

Lower level drivers are variously called HBA -(host bus adapter) drivers, host drivers (HD) or pseudo adapter drivers. -The latter alludes to the fact that a lower level driver may be a -bridge to another IO subsystem (and the "ide-scsi" driver is an example -of this). There can be many lower level drivers active in a running -system, but only one per hardware type. For example, the aic7xxx driver -controls adaptec controllers based on the 7xxx chip series. Most lower -level drivers can control one or more scsi hosts (a.k.a. scsi initiators). - - -This document can been found in an ASCII text file in the linux kernel -source: Documentation/scsi/scsi_mid_low_api.txt . -It currently hold a little more information than this document. The -drivers/scsi/hosts.h and -drivers/scsi/scsi.h headers contain descriptions of members -of important structures for the scsi subsystem. - - - - - Driver structure - -Traditionally a lower level driver for the scsi subsystem has been -at least two files in the drivers/scsi directory. For example, a -driver called "xyz" has a header file "xyz.h" and a source file -"xyz.c". [Actually there is no good reason why this couldn't all -be in one file.] Some drivers that have been ported to several operating -systems (e.g. aic7xxx which has separate files for generic and -OS-specific code) have more than two files. Such drivers tend to have -their own directory under the drivers/scsi directory. - - -scsi_module.c is normally included at the end of a lower -level driver. For it to work a declaration like this is needed before -it is included: - - static Scsi_Host_Template driver_template = DRIVER_TEMPLATE; - /* DRIVER_TEMPLATE should contain pointers to supported interface - functions. Scsi_Host_Template is defined hosts.h */ - #include "scsi_module.c" - - - -The scsi_module.c assumes the name "driver_template" is appropriately -defined. It contains 2 functions: - - - init_this_scsi_driver() called during builtin and module driver - initialization: invokes mid level's scsi_register_host() - - - exit_this_scsi_driver() called during closedown: invokes - mid level's scsi_unregister_host() - - - - -When a new, lower level driver is being added to Linux, the following -files (all found in the drivers/scsi directory) will need some attention: -Makefile, Config.help and Config.in . It is probably best to look at what -an existing lower level driver does in this regard. - - - - - Interface Functions -!EDocumentation/scsi/scsi_mid_low_api.txt - - - - Locks - -Each Scsi_Host instance has a spin_lock called Scsi_Host::default_lock -which is initialized in scsi_register() [found in hosts.c]. Within the -same function the Scsi_Host::host_lock pointer is initialized to point -at default_lock with the scsi_assign_lock() function. Thereafter -lock and unlock operations performed by the mid level use the -Scsi_Host::host_lock pointer. - - -Lower level drivers can override the use of Scsi_Host::default_lock by -using scsi_assign_lock(). The earliest opportunity to do this would -be in the detect() function after it has invoked scsi_register(). It -could be replaced by a coarser grain lock (e.g. per driver) or a -lock of equal granularity (i.e. per host). Using finer grain locks -(e.g. per scsi device) may be possible by juggling locks in -queuecommand(). - - - - - Changes since lk 2.4 series - -io_request_lock has been replaced by several finer grained locks. The lock -relevant to lower level drivers is Scsi_Host::host_lock and there is one -per scsi host. - - -The older error handling mechanism has been removed. This means the -lower level interface functions abort() and reset() have been removed. - - -In the 2.4 series the scsi subsystem configuration descriptions were -aggregated with the configuration descriptions from all other Linux -subsystems in the Documentation/Configure.help file.

Similar work-alike -chips from Lite-On, Macronics, ASIX, Compex and other listed below are also -supported. - - - -These chips are used on at least 140 unique PCI board designs. The great -number of chips and board designs supported is the reason for the -driver size and complexity. Almost of the increasing complexity is in the -board configuration and media selection code. There is very little -increasing in the operational critical path length. - - - - - Board-specific Settings - - -PCI bus devices are configured by the system at boot time, so no jumpers -need to be set on the board. The system BIOS preferably should assign the -PCI INTA signal to an otherwise unused system IRQ line. - - - -Some boards have EEPROMs tables with default media entry. The factory default -is usually "autoselect". This should only be overridden when using -transceiver connections without link beat e.g. 10base2 or AUI, or (rarely!) -for forcing full-duplex when used with old link partners that do not do -autonegotiation. - - - - - Driver Operation - -Ring buffers - - -The Tulip can use either ring buffers or lists of Tx and Rx descriptors. -This driver uses statically allocated rings of Rx and Tx descriptors, set at -compile time by RX/TX_RING_SIZE. This version of the driver allocates skbuffs -for the Rx ring buffers at open() time and passes the skb->data field to the -Tulip as receive data buffers. When an incoming frame is less than -RX_COPYBREAK bytes long, a fresh skbuff is allocated and the frame is -copied to the new skbuff. When the incoming frame is larger, the skbuff is -passed directly up the protocol stack and replaced by a newly allocated -skbuff. - - - -The RX_COPYBREAK value is chosen to trade-off the memory wasted by -using a full-sized skbuff for small frames vs. the copying costs of larger -frames. For small frames the copying cost is negligible (esp. considering -that we are pre-loading the cache with immediately useful header -information). For large frames the copying cost is non-trivial, and the -larger copy might flush the cache of useful data. A subtle aspect of this -choice is that the Tulip only receives into longword aligned buffers, thus -the IP header at offset 14 isn't longword aligned for further processing. -Copied frames are put into the new skbuff at an offset of "+2", thus copying -has the beneficial effect of aligning the IP header and preloading the -cache. - - - - -Synchronization - -The driver runs as two independent, single-threaded flows of control. One -is the send-packet routine, which enforces single-threaded use by the -dev->tbusy flag. The other thread is the interrupt handler, which is single -threaded by the hardware and other software. - - - -The send packet thread has partial control over the Tx ring and 'dev->tbusy' -flag. It sets the tbusy flag whenever it's queuing a Tx packet. If the next -queue slot is empty, it clears the tbusy flag when finished otherwise it sets -the 'tp->tx_full' flag. - - - -The interrupt handler has exclusive control over the Rx ring and records stats -from the Tx ring. (The Tx-done interrupt can't be selectively turned off, so -we can't avoid the interrupt overhead by having the Tx routine reap the Tx -stats.) After reaping the stats, it marks the queue entry as empty by setting -the 'base' to zero. Iff the 'tp->tx_full' flag is set, it clears both the -tx_full and tbusy flags. - - - - - - - - Errata - - -The old DEC databooks were light on details. -The 21040 databook claims that CSR13, CSR14, and CSR15 should each be the last -register of the set CSR12-15 written. Hmmm, now how is that possible? - - - -The DEC SROM format is very badly designed not precisely defined, leading to -part of the media selection junkheap below. Some boards do not have EEPROM -media tables and need to be patched up. Worse, other boards use the DEC -design kit media table when it isn't correct for their board. - - - -We cannot use MII interrupts because there is no defined GPIO pin to attach -them.

However, for the sake of efficiency, an explicit deregistration -is advisable. - -2. Response for a command: sent from the kernel in response to a userspace -command. The payload is a series of three attributes of type: - -a) TASKSTATS_TYPE_AGGR_PID/TGID : attribute containing no payload but indicates -a pid/tgid will be followed by some stats. - -b) TASKSTATS_TYPE_PID/TGID: attribute whose payload is the pid/tgid whose stats -is being returned. - -c) TASKSTATS_TYPE_STATS: attribute with a struct taskstsats as payload. The -same structure is used for both per-pid and per-tgid stats. - -3. New message sent by kernel whenever a task exits. The payload consists of a - series of attributes of the following type: - -a) TASKSTATS_TYPE_AGGR_PID: indicates next two attributes will be pid+stats -b) TASKSTATS_TYPE_PID: contains exiting task's pid -c) TASKSTATS_TYPE_STATS: contains the exiting task's per-pid stats -d) TASKSTATS_TYPE_AGGR_TGID: indicates next two attributes will be tgid+stats -e) TASKSTATS_TYPE_TGID: contains tgid of process to which task belongs -f) TASKSTATS_TYPE_STATS: contains the per-tgid stats for exiting task's process - - -per-tgid stats --------------- - -Taskstats provides per-process stats, in addition to per-task stats, since -resource management is often done at a process granularity and aggregating task -stats in userspace alone is inefficient and potentially inaccurate (due to lack -of atomicity). - -However, maintaining per-process, in addition to per-task stats, within the -kernel has space and time overheads. To address this, the taskstats code -accumalates each exiting task's statistics into a process-wide data structure. -When the last task of a process exits, the process level data accumalated also -gets sent to userspace (along with the per-task data). - -When a user queries to get per-tgid data, the sum of all other live threads in -the group is added up and added to the accumalated total for previously exited -threads of the same thread group. - -Extending taskstats -------------------- - -There are two ways to extend the taskstats interface to export more -per-task/process stats as patches to collect them get added to the kernel -in future: - -1. Adding more fields to the end of the existing struct taskstats. Backward - compatibility is ensured by the version number within the - structure. Userspace will use only the fields of the struct that correspond - to the version its using. - -2. Defining separate statistic structs and using the netlink attributes - interface to return them. Since userspace processes each netlink attribute - independently, it can always ignore attributes whose type it does not - understand (because it is using an older version of the interface). - - -Choosing between 1. and 2. is a matter of trading off flexibility and -overhead. If only a few fields need to be added, then 1. is the preferable -path since the kernel and userspace don't need to incur the overhead of -processing new netlink attributes.

This possibility gets compounded when the taskstats structure gets -extended and the number of cpus grows large. - -To avoid losing statistics, userspace should do one or more of the following: - -- increase the receive buffer sizes for the netlink sockets opened by -listeners to receive exit data. - -- create more listeners and reduce the number of cpus being listened to by -each listener. In the extreme case, there could be one listener for each cpu. -Users may also consider setting the cpu affinity of the listener to the subset -of cpus to which it listens, especially if they are listening to just one cpu. - -Despite these measures, if the userspace receives ENOBUFS error messages -indicated overflow of receive buffers, it should take measures to handle the -loss of data. - ----- diff --git a/Documentation/arm/SA1100/PCMCIA b/Documentation/arm/SA1100/PCMCIA deleted file mode 100644 index 5eb5d3ab3..000000000 --- a/Documentation/arm/SA1100/PCMCIA +++ /dev/null @@ -1,374 +0,0 @@ -Kernel Low-Level PCMCIA Interface Documentation -^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ -John G Dorsey -Updated: 30 June, 2000 - - -Note: this interface has not been finalized! -See also: http://www.cs.cmu.edu/~wearable/software/pcmcia-arm.html - - -Introduction - -Early versions of PCMCIA Card Services for StrongARM were designed to -permit a single socket driver to run on a variety of SA-1100 boards by -using a userland configuration process.

A striped RAID controller -actually has a head for each physical device in the logical RAID device. - -However, setting the antic_expire (see tunable parameters below) produces -very similar behavior to the deadline IO scheduler. - - -Selecting IO schedulers ------------------------ -To choose IO schedulers at boot time, use the argument 'elevator=deadline'. -'noop' and 'as' (the default) are also available. IO schedulers are assigned -globally at boot time only presently. - - -Anticipatory IO scheduler Policies ----------------------------------- -The as-iosched implementation implements several layers of policies -to determine when an IO request is dispatched to the disk controller. -Here are the policies outlined, in order of application. - -1. one-way Elevator algorithm. - -The elevator algorithm is similar to that used in deadline scheduler, with -the addition that it allows limited backward movement of the elevator -(i.e. seeks backwards). A seek backwards can occur when choosing between -two IO requests where one is behind the elevator's current position, and -the other is in front of the elevator's position. If the seek distance to -the request in back of the elevator is less than half the seek distance to -the request in front of the elevator, then the request in back can be chosen. -Backward seeks are also limited to a maximum of MAXBACK (1024*1024) sectors. -This favors forward movement of the elevator, while allowing opportunistic -"short" backward seeks. - -2. FIFO expiration times for reads and for writes. - -This is again very similar to the deadline IO scheduler. The expiration -times for requests on these lists is tunable using the parameters read_expire -and write_expire discussed below. When a read or a write expires in this way, -the IO scheduler will interrupt its current elevator sweep or read anticipation -to service the expired request. - -3. Read and write request batching - -A batch is a collection of read requests or a collection of write -requests. The as scheduler alternates dispatching read and write batches -to the driver. In the case a read batch, the scheduler submits read -requests to the driver as long as there are read requests to submit, and -the read batch time limit has not been exceeded (read_batch_expire). -The read batch time limit begins counting down only when there are -competing write requests pending. - -In the case of a write batch, the scheduler submits write requests to -the driver as long as there are write requests available, and the -write batch time limit has not been exceeded (write_batch_expire). -However, the length of write batches will be gradually shortened -when read batches frequently exceed their time limit. - -When changing between batch types, the scheduler waits for all requests -from the previous batch to complete before scheduling requests for the -next batch. - -The read and write fifo expiration times described in policy 2 above -are checked only when in scheduling IO of a batch for the corresponding -(read/write) type. So for example, the read FIFO timeout values are -tested only during read batches. Likewise, the write FIFO timeout -values are tested only during write batches. For this reason, -it is generally not recommended for the read batch time -to be longer than the write expiration time, nor for the write batch -time to exceed the read expiration time (see tunable parameters below). - -When the IO scheduler changes from a read to a write batch, -it begins the elevator from the request that is on the head of the -write expiration FIFO. Likewise, when changing from a write batch to -a read batch, scheduler begins the elevator from the first entry -on the read expiration FIFO. - -4. Read anticipation. - -Read anticipation occurs only when scheduling a read batch. -This implementation of read anticipation allows only one read request -to be dispatched to the disk controller at a time. In -contrast, many write requests may be dispatched to the disk controller -at a time during a write batch. It is this characteristic that can make -the anticipatory scheduler perform anomalously with controllers supporting -TCQ, or with hardware striped RAID devices. Setting the antic_expire -queue paramter (see below) to zero disables this behavior, and the anticipatory -scheduler behaves essentially like the deadline scheduler. - -When read anticipation is enabled (antic_expire is not zero), reads -are dispatched to the disk controller one at a time. -At the end of each read request, the IO scheduler examines its next -candidate read request from its sorted read list. If that next request -is from the same process as the request that just completed, -or if the next request in the queue is "very close" to the -just completed request, it is dispatched immediately. Otherwise, -statistics (average think time, average seek distance) on the process -that submitted the just completed request are examined. If it seems -likely that that process will submit another request soon, and that -request is likely to be near the just completed request, then the IO -scheduler will stop dispatching more read requests for up time (antic_expire) -milliseconds, hoping that process will submit a new request near the one -that just completed. If such a request is made, then it is dispatched -immediately. If the antic_expire wait time expires, then the IO scheduler -will dispatch the next read request from the sorted read queue. - -To decide whether an anticipatory wait is worthwhile, the scheduler -maintains statistics for each process that can be used to compute -mean "think time" (the time between read requests), and mean seek -distance for that process. One observation is that these statistics -are associated with each process, but those statistics are not associated -with a specific IO device. So for example, if a process is doing IO -on several file systems on separate devices, the statistics will be -a combination of IO behavior from all those devices. - - -Tuning the anticipatory IO scheduler ------------------------------------- -When using 'as', the anticipatory IO scheduler there are 5 parameters under -/sys/block/*/iosched/. All are units of milliseconds. - -The parameters are: -* read_expire - Controls how long until a read request becomes "expired". It also controls the - interval between which expired requests are served, so set to 50, a request - might take anywhere < 100ms to be serviced _if_ it is the next on the - expired list. Obviously request expiration strategies won't make the disk - go faster. The result basically equates to the timeslice a single reader - gets in the presence of other IO. 100*((seek time / read_expire) + 1) is - very roughly the % streaming read efficiency your disk should get with - multiple readers. - -* read_batch_expire - Controls how much time a batch of reads is given before pending writes are - served. A higher value is more efficient. This might be set below read_expire - if writes are to be given higher priority than reads, but reads are to be - as efficient as possible when there are no writes. Generally though, it - should be some multiple of read_expire. - -* write_expire, and -* write_batch_expire are equivalent to the above, for writes. - -* antic_expire - Controls the maximum amount of time we can anticipate a good read (one - with a short seek distance from the most recently completed request) before - giving up. Many other factors may cause anticipation to be stopped early, - or some processes will not be "anticipated" at all. Should be a bit higher - for big seek time devices though not a linear correspondence - most - processes have only a few ms thinktime. - diff --git a/Documentation/block/switching-sched.txt b/Documentation/block/switching-sched.txt deleted file mode 100644 index 5fa130a67..000000000 --- a/Documentation/block/switching-sched.txt +++ /dev/null @@ -1,22 +0,0 @@ -As of the Linux 2.6.10 kernel, it is now possible to change the -IO scheduler for a given block device on the fly (thus making it possible, -for instance, to set the CFQ scheduler for the system default, but -set a specific device to use the anticipatory or noop schedulers - which -can improve that device's throughput). - -To set a specific scheduler, simply do this: - -echo SCHEDNAME > /sys/block/DEV/queue/scheduler - -where SCHEDNAME is the name of a defined IO scheduler, and DEV is the -device name (hda, hdb, sga, or whatever you happen to have). - -The list of defined schedulers can be found by simply doing -a "cat /sys/block/DEV/queue/scheduler" - the list of valid names -will be displayed, with the currently selected scheduler in brackets: - -# cat /sys/block/hda/queue/scheduler -noop anticipatory deadline [cfq] -# echo anticipatory > /sys/block/hda/queue/scheduler -# cat /sys/block/hda/queue/scheduler -noop [anticipatory] deadline cfq diff --git a/Documentation/cdrom/mcd b/Documentation/cdrom/mcd deleted file mode 100644 index 39537f9f0..000000000 --- a/Documentation/cdrom/mcd +++ /dev/null @@ -1,4 +0,0 @@ -This driver does not support XA or MultiSession CDs (PhotoCDs).

All drivers, except system drivers, must call either register_con_driver() - or take_over_console(). register_con_driver() will just add the driver to - the console's internal list. It won't take over the - console. take_over_console(), as it name implies, will also take over (or - bind to) the console. - -2. All resources allocated during con->con_init() must be released in - con->con_deinit(). - -3. All resources allocated in con->con_startup() must be released when the - driver, which was previously bound, becomes unbound. The console layer - does not have a complementary call to con->con_startup() so it's up to the - driver to check when it's legal to release these resources. Calling - con_is_bound() in con->con_deinit() will help. If the call returned - false(), then it's safe to release the resources. This balance has to be - ensured because con->con_startup() can be called again when a request to - rebind the driver to the console arrives. - -4. Upon exit of the driver, ensure that the driver is totally unbound. If the - condition is satisfied, then the driver must call unregister_con_driver() - or give_up_console(). - -5. unregister_con_driver() can also be called on conditions which make it - impossible for the driver to service console requests. This can happen - with the framebuffer console that suddenly lost all of its drivers. - -The current crop of console drivers should still work correctly, but binding -and unbinding them may cause problems.

Compiling - -Since the driver is in the linux kernel, activating the driver in -your favorite config-environment should sufficient. I recommend -to compile the driver as module.

For myself -I used mplayer, dvbscan, tzap and kaxtv, they are working. Using the device -in vdr is working now also. - -2. Known problems and bugs - -- Don't remove the USB device while running an DVB application, your system will die. - -2.1. Adding support for devices - -It is not possible to determine the range of devices based on the DiBcom -reference designs. This is because the reference design of DiBcom can be sold -to thirds, without telling DiBcom (so done with the Twinhan VP7041 and -the HAMA device). - -When you think you have a device like this and the driver does not recognizes it, -please send the ****load*.inf and the ****cap*.inf of the Windows driver to me. - -Sometimes the Vendor or Product ID is identical to the ones of Twinhan, even -though it is not a Twinhan device (e.g. HAMA), then please send me the name -of the device. I will add it to this list in order to make this clear to -others. - -If you are familar with C you can also add the VID and PID of the device to -the dvb-dibusb-core.c-file and create a patch and send it over to me or to -the linux-dvb mailing list, _after_ you have tried compiling and modprobing -it. - -2.2. USB1.1 Bandwidth limitation - -Most of the currently supported devices are USB1.1 and thus they have a -maximum bandwidth of about 5-6 MBit/s when connected to a USB2.0 hub. -This is not enough for receiving the complete transport stream of a -DVB-T channel (which can be about 16 MBit/s). Normally this is not a -problem, if you only want to watch TV (this does not apply for HDTV), -but watching a channel while recording another channel on the same -frequency simply does not work very well. This applies to all USB1.1 -DVB-T devices, not just dibusb) - -Update: For the USB1.1 and VDR some work has been done (patches and comments -are still very welcome). Maybe the problem is solved in the meantime because I -now use the dmx_sw_filter function instead of dmx_sw_filter_packet. I hope the -linux-dvb software filter is able to get the best of the garbled TS. - -The bug, where the TS is distorted by a heavy usage of the device is gone -definitely. All dibusb-devices I was using (Twinhan, Kworld, DiBcom) are -working like charm now with VDR. Sometimes I even was able to record a channel -and watch another one. - -2.3. Comments - -Patches, comments and suggestions are very very welcome. - -3.

Both parameters are meant to be - used ad-hoc and for single devices only, i.e. not in modprobe.conf, - therefore the impact of this feature replacement should be low. -Who: Stefan Richter - ---------------------------- - -What: Video4Linux API 1 ioctls and video_decoder.h from Video devices. -When: July 2006 -Why: V4L1 AP1 was replaced by V4L2 API. during migration from 2.4 to 2.6 - series. The old API have lots of drawbacks and don't provide enough - means to work with all video and audio standards. The newer API is - already available on the main drivers and should be used instead. - Newer drivers should use v4l_compat_translate_ioctl function to handle - old calls, replacing to newer ones. - Decoder iocts are using internally to allow video drivers to - communicate with video decoders. This should also be improved to allow - V4L2 calls being translated into compatible internal ioctls. -Who: Mauro Carvalho Chehab - ---------------------------- - -What: PCMCIA control ioctl (needed for pcmcia-cs [cardmgr, cardctl]) -When: November 2005 -Files: drivers/pcmcia/: pcmcia_ioctl.c -Why: With the 16-bit PCMCIA subsystem now behaving (almost) like a - normal hotpluggable bus, and with it using the default kernel - infrastructure (hotplug, driver core, sysfs) keeping the PCMCIA - control ioctl needed by cardmgr and cardctl from pcmcia-cs is - unnecessary, and makes further cleanups and integration of the - PCMCIA subsystem into the Linux kernel device driver model more - difficult.

The Kernel interface is compatible, so the old - ip[6]tables "QUEUE" targets still work and will transparently handle - all packets into nfnetlink queue number 0. Userspace users will have - to link against API-compatible library on top of libnfnetlink_queue - instead of the current 'libipq'. -Who: Harald Welte - ---------------------------- - -What: remove EXPORT_SYMBOL(kernel_thread) -When: August 2006 -Files: arch/*/kernel/*_ksyms.c -Why: kernel_thread is a low-level implementation detail. Drivers should - use the API instead which shields them from - implementation details and provides a higherlevel interface that - prevents bugs and code duplication -Who: Christoph Hellwig - ---------------------------- - -What: CONFIG_FORCED_INLINING -When: June 2006 -Why: Config option is there to see if gcc is good enough.

This - was never done by Linux. The invalid (e.g. negative timevals) were - silently converted to more or less random timeouts and intervals. - Until the removal a per boot limited number of warnings is printed - and the timevals are sanitized. - -Who: Thomas Gleixner - ---------------------------- - -What: I2C interface of the it87 driver -When: January 2007 -Why: The ISA interface is faster and should be always available.

Userspace should - poll the /proc/mounts file instead to detect this properly. -Who: Greg Kroah-Hartman - ---------------------------- - -What: USB driver API moves to EXPORT_SYMBOL_GPL -When: Febuary 2008 -Files: include/linux/usb.h, drivers/usb/core/driver.c -Why: The USB subsystem has changed a lot over time, and it has been - possible to create userspace USB drivers using usbfs/libusb/gadgetfs - that operate as fast as the USB bus allows. Because of this, the USB - subsystem will not be allowing closed source kernel drivers to - register with it, after this grace period is over. If anyone needs - any help in converting their closed source drivers over to use the - userspace filesystems, please contact the - linux-usb-devel@lists.sourceforge.net mailing list, and the developers - there will be glad to help you out. -Who: Greg Kroah-Hartman - ---------------------------- - -What: find_trylock_page -When: January 2007 -Why: The interface no longer has any callers left in the kernel. It - is an odd interface (compared with other find_*_page functions), in - that it does not take a refcount to the page, only the page lock. - It should be replaced with find_get_page or find_lock_page if possible. - This feature removal can be reevaluated if users of the interface - cannot cleanly use something else. -Who: Nick Piggin - ---------------------------- - -What: Support for the MIPS EV96100 evaluation board -When: September 2006 -Why: Does no longer build since at least November 15, 2003, apparently - no userbase left. -Who: Ralf Baechle - ---------------------------- - -What: Support for the Momentum / PMC-Sierra Jaguar ATX evaluation board -When: September 2006 -Why: Does no longer build since quite some time, and was never popular, - due to the platform being replaced by successor models.

This feature removal can be reevaluated if - someone shows interest in the drivers, fixes them and takes over - maintenance. - http://marc.theaimsgroup.com/?l=linux-mips&m=115040510817448 -Who: Jean Delvare - ---------------------------- - -What: Bridge netfilter deferred IPv4/IPv6 output hook calling -When: January 2007 -Why: The deferred output hooks are a layering violation causing unusual - and broken behaviour on bridge devices. Examples of things they - break include QoS classifation using the MARK or CLASSIFY targets, - the IPsec policy match and connection tracking with VLANs on a - bridge.

This should instantiate that object in the cache if it can, or - return -ENOBUFS or -ENOMEM if it can't. - - (*) Increment object refcount [mandatory]: - - struct fscache_object *(*grab_object)(struct fscache_object *object) - - This method is called to increment the reference count on an object. It - may fail (for instance if the cache is being withdrawn) by returning NULL. - It should return the object pointer if successful. - - (*) Lock/Unlock object [mandatory]: - - void (*lock_object)(struct fscache_object *object) - void (*unlock_object)(struct fscache_object *object) - - These methods are used to exclusively lock an object. It must be possible - to schedule with the lock held, so a spinlock isn't sufficient. - - (*) Pin/Unpin object [optional]: - - int (*pin_object)(struct fscache_object *object) - void (*unpin_object)(struct fscache_object *object) - - These methods are used to pin an object into the cache. Once pinned an - object cannot be reclaimed to make space. Return -ENOSPC if there's not - enough space in the cache to permit this. - - (*) Update object [mandatory]: - - int (*update_object)(struct fscache_object *object) - - This is called to update the index entry for the specified object. The - new information should be in object->cookie->netfs_data. This can be - obtained by calling object->cookie->def->get_aux()/get_attr(). - - (*) Release object reference [mandatory]: - - void (*put_object)(struct fscache_object *object) - - This method is used to discard a reference to an object. The object may - be destroyed when all the references held by FS-Cache are released. - - (*) Synchronise a cache [mandatory]: - - void (*sync)(struct fscache_cache *cache) - - This is called to ask the backend to synchronise a cache with its backing - device. - - (*) Dissociate a cache [mandatory]: - - void (*dissociate_pages)(struct fscache_cache *cache) - - This is called to ask a cache to perform any page dissociations as part of - cache withdrawal. - - (*) Set the data size on a cache file [mandatory]: - - int (*set_i_size)(struct fscache_object *object, loff_t i_size); - - This is called to indicate to the cache the maximum size a file may reach. - The cache may use this to reserve space on the cache. It may also return - -ENOBUFS to indicate that insufficient space is available to expand the - metadata used to track the data. It should return 0 if successful or - -ENOMEM or -EIO on error. - - (*) Reserve cache space for an object's data [optional]: - - int (*reserve_space)(struct fscache_object *object, loff_t size); - - This is called to request that cache space be reserved to hold the data - for an object and the metadata used to track it. Zero size should be - taken as request to cancel a reservation. - - This should return 0 if successful, -ENOSPC if there isn't enough space - available, or -ENOMEM or -EIO on other errors. - - The reservation may exceed the size of the object, thus permitting future - expansion. If the amount of space consumed by an object would exceed the - reservation, it's permitted to refuse requests to allocate pages, but not - required. An object may be pruned down to its reservation size if larger - than that already. - - (*) Request page be read from cache [mandatory]: - - int (*read_or_alloc_page)(struct fscache_object *object, - struct page *page, - fscache_rw_complete_t end_io_func, - void *end_io_data, - gfp_t gfp) - - This is called to attempt to read a netfs page from the cache, or to - reserve a backing block if not. FS-Cache will have done as much checking - as it can before calling, but most of the work belongs to the backend. - - If there's no page in the cache, then -ENODATA should be returned if the - backend managed to reserve a backing block; -ENOBUFS, -ENOMEM or -EIO if - it didn't. - - If there is a page in the cache, then a read operation should be queued - and 0 returned. When the read finishes, end_io_func() should be called - with the following arguments: - - (*end_io_func)(object->cookie->netfs_data, - page, - end_io_data, - error); - - The mark_pages_cached() cookie operation should be called for the page if - any cache metadata is retained. This will indicate to the netfs that the - page needs explicit uncaching.

Such pages must also be removed from the pages list and nr_pages - decremented per page. - - If there was an error such as -ENOMEM, then that should be returned; else - if one or more pages couldn't be read or allocated, then -ENOBUFS should - be returned; else if one or more pages couldn't be read, then -ENODATA - should be returned. If all the pages are dispatched then 0 should be - returned. - - (*) Request page be allocated in the cache [mandatory]: - - int (*allocate_page)(struct fscache_object *object, - struct page *page, - gfp_t gfp) - - This is like read_or_alloc_page(), except that it shouldn't read from the - cache, even if there's data there that could be retrieved. It should, - however, set up any internal metadata required such that write_page() can - write to the cache. - - If there's no backing block available, then -ENOBUFS should be returned - (or -ENOMEM or -EIO if there were other problems). If a block is - successfully allocated, then the netfs page should be marked and 0 - returned. - - (*) Request page be written to cache [mandatory]: - - int (*write_page)(struct fscache_object *object, - struct page *page, - fscache_rw_complete_t end_io_func, - void *end_io_data, - gfp_t gfp) - - This is called to write from a page on which there was a previously - successful read_or_alloc_page() call. FS-Cache filters out pages that - don't have mappings. - - If there's no backing block available, then -ENOBUFS should be returned - (or -ENOMEM or -EIO if there were other problems). - - If the write operation could be queued, then 0 should be returned. When - the write completes, end_io_func() should be called with the following - arguments: - - (*end_io_func)(object->cookie->netfs_data, - page, - end_io_data, - error); - - (*) Discard retained per-page metadata [mandatory]: - - void (*uncache_pages)(struct fscache_object *object, - struct pagevec *pagevec) - - This is called when one or more netfs pages are being evicted from the - pagecache.

This means it can be -placed on the same medium as a live set of data, and will expand to make use of -spare space and automatically contract when the set of data requires more -space. - - -============ -REQUIREMENTS -============ - -The use of CacheFiles and its daemon requires the following features to be -available in the system and in the cache filesystem: - - - dnotify. - - - extended attributes (xattrs). - - - openat() and friends. - - - bmap() support on files in the filesystem (FIBMAP ioctl). - - - The use of bmap() to detect a partial page at the end of the file. - -It is strongly recommended that the "dir_index" option is enabled on Ext3 -filesystems being used as a cache. - - -============= -CONFIGURATION -============= - -The cache is configured by a script in /etc/cachefilesd.conf. These commands -set up cache ready for use. The following script commands are available: - - (*) brun % - (*) bcull % - (*) bstop % - - Configure the culling limits. Optional. See the section on culling - The defaults are 7%, 5% and 1% respectively. - - (*) dir - - Specify the directory containing the root of the cache. Mandatory. - - (*) tag - - Specify a tag to FS-Cache to use in distinguishing multiple caches. - Optional. The default is "CacheFiles". - - (*) debug - - Specify a numeric bitmask to control debugging in the kernel module. - Optional. The default is zero (all off).

The -kernel module contains its own very cut-down path walking facility that ignores -mountpoints, but the daemon can't avoid them. - -Do not create, rename or unlink files and directories in the cache whilst the -cache is active, as this may cause the state to become uncertain. - -Renaming files in the cache might make objects appear to be other objects (the -filename is part of the lookup key). - -Do not change or remove the extended attributes attached to cache files by the -cache as this will cause the cache state management to get confused. - -Do not create files or directories in the cache, lest the cache get confused or -serve incorrect data. - -Do not chmod files in the cache. The module creates things with minimal -permissions to prevent random users being able to access them directly. - - -============= -CACHE CULLING -============= - -The cache may need culling occasionally to make space. This involves -discarding objects from the cache that have been used less recently than -anything else. Culling is based on the access time of data objects. Empty -directories are culled if not in use. - -Cache culling is done on the basis of the percentage of blocks available in the -underlying filesystem. There are three "limits": - - (*) brun - - If the amount of available space in the cache rises above this limit, then - culling is turned off. - - (*) bcull - - If the amount of available space in the cache falls below this limit, then - culling is started. - - (*) bstop - - If the amount of available space in the cache falls below this limit, then - no further allocation of disk space is permitted until culling has raised - the amount above this limit again. - -These must be configured thusly: - - 0 <= bstop < bcull < brun < 100 - -Note that these are percentages of available space, and do _not_ appear as 100 -minus the percentage displayed by the "df" program. - -The userspace daemon scans the cache to build up a table of cullable objects. -These are then culled in least recently used order. A new scan of the cache is -started as soon as space is made in the table. Objects will be skipped if -their atimes have changed or if the kernel module says it is still using them. - - -=============== -CACHE STRUCTURE -=============== - -The CacheFiles module will create two directories in the directory it was -given: - - (*) cache/ - - (*) graveyard/ - -The active cache objects all reside in the first directory. The CacheFiles -kernel module moves any retired or culled objects that it can't simply unlink -to the graveyard from which the daemon will actually delete them. - -The daemon uses dnotify to monitor the graveyard directory, and will delete -anything that appears therein. - - -The module represents index objects as directories with the filename "I..." or -"J...". Note that the "cache/" directory is itself a special index. - -Data objects are represented as files if they have no children, or directories -if they do. Their filenames all begin "D..." or "E...". If represented as a -directory, data objects will have a file in the directory called "data" that -actually holds the data. - -Special objects are similar to data objects, except their filenames begin -"S..." or "T...". - - -If an object has children, then it will be represented as a directory. -Immediately in the representative directory are a collection of directories -named for hash values of the child object keys with an '@' prepended.

This is specified -using a record of the following structure: - - struct fscache_netfs { - uint32_t version; - const char *name; - struct fscache_netfs_operations *ops; - struct fscache_cookie *primary_index; - ... - }; - -This first three fields should be filled in before registration, and the fourth -will be filled in by the registration function; any other fields should just be -ignored and are for internal use only. - -The fields are: - - (1) The name of the netfs (used as the key in the toplevel index). - - (2) The version of the netfs (if the name matches but the version doesn't, the - entire in-cache hierarchy for this netfs will be scrapped and begun - afresh). - - (3) The operations table is defined as follows: - - struct fscache_netfs_operations { - }; - - Currently there aren't any functions here. - - (4) The cookie representing the primary index will be allocated according to - another parameter passed into the registration function. - -For example, kAFS (linux/fs/afs/) uses the following definitions to describe -itself: - - static struct fscache_netfs_operations afs_cache_ops = { - }; - - struct fscache_netfs afs_cache_netfs = { - .version = 0, - .name = "afs", - .ops = &afs_cache_ops, - }; - - -================ -INDEX DEFINITION -================ - -Indices are used for two purposes: - - (1) To aid the finding of a file based on a series of keys (such as AFS's - "cell", "volume ID", "vnode ID"). - - (2) To make it easier to discard a subset of all the files cached based around - a particular key - for instance to mirror the removal of an AFS volume. - -However, since it's unlikely that any two netfs's are going to want to define -their index hierarchies in quite the same way, FS-Cache tries to impose as few -restraints as possible on how an index is structured and where it is placed in -the tree. The netfs can even mix indices and data files at the same level, but -it's not recommended. - -Each index entry consists of a key of indeterminate length plus some auxilliary -data, also of indeterminate length. - -There are some limits on indices: - - (1) Any index containing non-index objects should be restricted to a single - cache. Any such objects created within an index will be created in the - first cache only. The cache in which an index is created can be - controlled by cache tags (see below). - - (2) The entry data must be atomically journallable, so it is limited to about - 400 bytes at present. At least 400 bytes will be available. - - (3) The depth of the index tree should be judged with care as the search - function is recursive. Too many layers will run the kernel out of stack. - - -================= -OBJECT DEFINITION -================= - -To define an object, a structure of the following type should be filled out: - - struct fscache_object_def - { - uint8_t name[16]; - uint8_t type; - - struct fscache_cache_tag *(*select_cache)( - const void *parent_netfs_data, - const void *cookie_netfs_data); - - uint16_t (*get_key)(const void *cookie_netfs_data, - void *buffer, - uint16_t bufmax); - - void (*get_attr)(const void *cookie_netfs_data, - uint64_t *size); - - uint16_t (*get_aux)(const void *cookie_netfs_data, - void *buffer, - uint16_t bufmax); - - fscache_checkaux_t (*check_aux)(void *cookie_netfs_data, - const void *data, - uint16_t datalen); - - void (*get_context)(void *cookie_netfs_data, void *context); - - void (*put_context)(void *cookie_netfs_data, void *context); - - void (*mark_pages_cached)(void *cookie_netfs_data, - struct address_space *mapping, - struct pagevec *cached_pvec); - - void (*now_uncached)(void *cookie_netfs_data); - }; - -This has the following fields: - - (1) The type of the object [mandatory]. - - This is one of the following values: - - (*) FSCACHE_COOKIE_TYPE_INDEX - - This defines an index, which is a special FS-Cache type. - - (*) FSCACHE_COOKIE_TYPE_DATAFILE - - This defines an ordinary data file. - - (*) Any other value between 2 and 255 - - This defines an extraordinary object such as an XATTR. - - (2) The name of the object type (NUL terminated unless all 16 chars are used) - [optional]. - - (3) A function to select the cache in which to store an index [optional]. - - This function is invoked when an index needs to be instantiated in a cache - during the instantiation of a non-index object. Only the immediate index - parent for the non-index object will be queried. Any indices above that - in the hierarchy may be stored in multiple caches. This function does not - need to be supplied for any non-index object or any index that will only - have index children. - - If this function is not supplied or if it returns NULL then the first - cache in the parent's list will be chosed, or failing that, the first - cache in the master list. - - (4) A function to retrieve an object's key from the netfs [mandatory]. - - This function will be called with the netfs data that was passed to the - cookie acquisition function and the maximum length of key data that it may - provide. It should write the required key data into the given buffer and - return the quantity it wrote. - - (5) A function to retrieve attribute data from the netfs [optional]. - - This function will be called with the netfs data that was passed to the - cookie acquisition function. It should return the size of the file if - this is a data file. The size may be used to govern how much cache must - be reserved for this file in the cache. - - If the function is absent, a file size of 0 is assumed. - - (6) A function to retrieve auxilliary data from the netfs [optional]. - - This function will be called with the netfs data that was passed to the - cookie acquisition function and the maximum length of auxilliary data that - it may provide. It should write the auxilliary data into the given buffer - and return the quantity it wrote. - - If this function is absent, the auxilliary data length will be set to 0. - - The length of the auxilliary data buffer may be dependent on the key - length. A netfs mustn't rely on being able to provide more than 400 bytes - for both. - - (7) A function to check the auxilliary data [optional]. - - This function will be called to check that a match found in the cache for - this object is valid. For instance with AFS it could check the auxilliary - data against the data version number returned by the server to determine - whether the index entry in a cache is still valid. - - If this function is absent, it will be assumed that matching objects in a - cache are always valid. - - If present, the function should return one of the following values: - - (*) FSCACHE_CHECKAUX_OKAY - the entry is okay as is - (*) FSCACHE_CHECKAUX_NEEDS_UPDATE - the entry requires update - (*) FSCACHE_CHECKAUX_OBSOLETE - the entry should be deleted - - This function can also be used to extract data from the auxilliary data in - the cache and copy it into the netfs's structures. - - (8) A pair of functions to manage contexts for the completion callback - [optional]. - - The cache read/write functions are passed a context which is then passed - to the I/O completion callback function. To ensure this context remains - valid until after the I/O completion is called, two functions may be - provided: one to get an extra reference on the context, and one to drop a - reference to it. - - If the context is not used or is a type of object that won't go out of - scope, then these functions are not required. These functions are not - required for indices as indices may not contain data. These functions may - be called in interrupt context and so may not sleep. - - (9) A function to mark a page as retaining cache metadata [mandatory]. - - This is called by the cache to indicate that it is retaining in-memory - information for this page and that the netfs should uncache the page when - it has finished. This does not indicate whether there's data on the disk - or not. Note that several pages at once may be presented for marking. - - kAFS and NFS use the PG_private bit on the page structure for this, but - that may not be appropriate in all cases. - - This function is not required for indices as they're not permitted data. - -(10) A function to unmark all the pages retaining cache metadata [mandatory]. - - This is called by FS-Cache to indicate that a backing store is being - unbound from a cookie and that all the marks on the pages should be - cleared to prevent confusion. Note that the cache will have torn down all - its tracking information so that the pages don't need to be explicitly - uncached. - - This function is not required for indices as they're not permitted data. - - -=================================== -NETWORK FILESYSTEM (UN)REGISTRATION -=================================== - -The first step is to declare the network filesystem to the cache. This also -involves specifying the layout of the primary index (for AFS, this would be the -"cell" level). - -The registration function is: - - int fscache_register_netfs(struct fscache_netfs *netfs); - -It just takes a pointer to the netfs definition. It returns 0 or an error as -appropriate. - -For kAFS, registration is done as follows: - - ret = fscache_register_netfs(&afs_cache_netfs); - -The last step is, of course, unregistration: - - void fscache_unregister_netfs(struct fscache_netfs *netfs); - - -================ -CACHE TAG LOOKUP -================ - -FS-Cache permits the use of more than one cache. To permit particular index -subtrees to be bound to particular caches, the second step is to look up cache -representation tags. This step is optional; it can be left entirely up to -FS-Cache as to which cache should be used. The problem with doing that is that -FS-Cache will always pick the first cache that was registered. - -To get the representation for a named tag: - - struct fscache_cache_tag *fscache_lookup_cache_tag(const char *name); - -This takes a text string as the name and returns a representation of a tag. It -will never return an error. It may return a dummy tag, however, if it runs out -of memory; this will inhibit caching with this tag. - -Any representation so obtained must be released by passing it to this function: - - void fscache_release_cache_tag(struct fscache_cache_tag *tag); - -The tag will be retrieved by FS-Cache when it calls the object definition -operation select_cache(). - - -================== -INDEX REGISTRATION -================== - -The third step is to inform FS-Cache about part of an index hierarchy that can -be used to locate files. This is done by requesting a cookie for each index in -the path to the file: - - struct fscache_cookie * - fscache_acquire_cookie(struct fscache_cookie *parent, - struct fscache_object_def *def, - void *netfs_data); - -This function creates an index entry in the index represented by parent, -filling in the index entry by calling the operations pointed to by def. - -Note that this function never returns an error - all errors are handled -internally. It may also return NULL to indicate no cookie. It is quite -acceptable to pass this token back to this function as the parent to another -acquisition (or even to the relinquish cookie, read page and write page -functions - see below). - -Note also that no indices are actually created in a cache until a non-index -object needs to be created somewhere down the hierarchy. Furthermore, an index -may be created in several different caches independently at different times. -This is all handled transparently, and the netfs doesn't see any of it. - -For example, with AFS, a cell would be added to the primary index. This index -entry would have a dependent inode containing a volume location index for the -volume mappings within this cell: - - cell->cache = - fscache_acquire_cookie(afs_cache_netfs.primary_index, - &afs_cell_cache_index_def, - cell); - -Then when a volume location was accessed, it would be entered into the cell's -index and an inode would be allocated that acts as a volume type and hash chain -combination: - - vlocation->cache = - fscache_acquire_cookie(cell->cache, - &afs_vlocation_cache_index_def, - vlocation); - -And then a particular flavour of volume (R/O for example) could be added to -that index, creating another index for vnodes (AFS inode equivalents): - - volume->cache = - fscache_acquire_cookie(vlocation->cache, - &afs_volume_cache_index_def, - volume); - - -====================== -DATA FILE REGISTRATION -====================== - -The fourth step is to request a data file be created in the cache. This is -identical to index cookie acquisition. The only difference is that the type in -the object definition should be something other than index type. - - vnode->cache = - fscache_acquire_cookie(volume->cache, - &afs_vnode_cache_object_def, - vnode); - - -================================= -MISCELLANEOUS OBJECT REGISTRATION -================================= - -An optional step is to request an object of miscellaneous type be created in -the cache. This is almost identical to index cookie acquisition. The only -difference is that the type in the object definition should be something other -than index type. Whilst the parent object could be an index, it's more likely -it would be some other type of object such as a data file. - - xattr->cache = - fscache_acquire_cookie(vnode->cache, - &afs_xattr_cache_object_def, - xattr); - -Miscellaneous objects might be used to store extended attributes or directory -entries for example. - - -========================== -SETTING THE DATA FILE SIZE -========================== - -The fifth step is to set the size of the file. This doesn't automatically -reserve any space in the cache, but permits the cache to adjust its metadata -for data tracking appropriately: - - int fscache_set_i_size(struct fscache_cookie *cookie, loff_t i_size); - -The cache will return -ENOBUFS if there is no backing cache or if there is no -space to allocate any extra metadata required in the cache. - -Note that attempts to read or write data pages in the cache over this size may -be rebuffed with -ENOBUFS. - - -===================== -PAGE READ/ALLOC/WRITE -===================== - -And the sixth step is to store and retrieve pages in the cache. There are -three functions that are used to do this. - -Note: - - (1) A page should not be re-read or re-allocated without uncaching it first. - - (2) A read or allocated page must be uncached when the netfs page is released - from the pagecache. - - (3) A page should only be written to the cache if previous read or allocated. - -This permits the cache to maintain its page tracking in proper order. - - -PAGE READ ---------- - -Firstly, the netfs should ask FS-Cache to examine the caches and read the -contents cached for a particular page of a particular file if present, or else -allocate space to store the contents if not: - - typedef - void (*fscache_rw_complete_t)(struct page *page, - void *context, - int error); - - int fscache_read_or_alloc_page(struct fscache_cookie *cookie, - struct page *page, - fscache_rw_complete_t end_io_func, - void *end_io_data, - gfp_t gfp); - -The cookie argument must specify a cookie for an object that isn't an index, -the page specified will have the data loaded into it (and is also used to -specify the page number), and the gfp argument is used to control how any -memory allocations made are satisfied. - -If the cookie indicates the inode is not cached: - - (1) The function will return -ENOBUFS. - -Else if there's a copy of the page resident in the cache: - - (1) The mark_pages_cached() cookie operation will be called on that page. - - (2) The function will submit a request to read the data from the cache's - backing device directly into the page specified. - - (3) The function will return 0. - - (4) When the read is complete, end_io_func() will be invoked with: - - (*) The netfs data supplied when the cookie was created. - - (*) The page descriptor. - - (*) The context argument passed to the above function. This will be - maintained with the get_context/put_context functions mentioned above. - - (*) An argument that's 0 on success or negative for an error code. - - If an error occurs, it should be assumed that the page contains no usable - data. - - end_io_func() will be called in process context if the read is results in - an error, but it might be called in interrupt context if the read is - successful. - -Otherwise, if there's not a copy available in cache, but the cache may be able -to store the page: - - (1) The mark_pages_cached() cookie operation will be called on that page. - - (2) A block may be reserved in the cache and attached to the object at the - appropriate place. - - (3) The function will return -ENODATA. - -This function may also return -ENOMEM or -EINTR, in which case it won't have -read any data from the cache. - - -PAGE ALLOCATE -------------- - -Alternatively, if there's not expected to be any data in the cache for a page -because the file has been extended, a block can simply be allocated instead: - - int fscache_alloc_page(struct fscache_cookie *cookie, - struct page *page, - gfp_t gfp); - -This is similar to the fscache_read_or_alloc_page() function, except that it -never reads from the cache. It will return 0 if a block has been allocated, -rather than -ENODATA as the other would. One or the other must be performed -before writing to the cache. - -The mark_pages_cached() cookie operation will be called on the page if -successful. - - -PAGE WRITE ----------- - -Secondly, if the netfs changes the contents of the page (either due to an -initial download or if a user performs a write), then the page should be -written back to the cache: - - int fscache_write_page(struct fscache_cookie *cookie, - struct page *page, - fscache_rw_complete_t end_io_func, - void *context, - gfp_t gfp); - -The cookie argument must specify a data file cookie, the page specified should -contain the data to be written (and is also used to specify the page number), -and the gfp argument is used to control how any memory allocations made are -satisfied. - -The page must have first been read or allocated successfully and must not have -been uncached before writing is performed. - -If the cookie indicates the inode is not cached then: - - (1) The function will return -ENOBUFS. - -Else if space can be allocated in the cache to hold this page: - - (1) The function will submit a request to write the data to cache's backing - device directly from the page specified. - - (2) The function will return 0. - - (3) When the write is complete the end_io_func() will be invoked with: - - (*) The netfs data supplied when the cookie was created. - - (*) The page descriptor. - - (*) The context argument passed to the function. This will be maintained - with the get_context/put_context functions mentioned above. - - (*) An argument that's 0 on success or negative for an error. - - If an error occurs, it can be assumed that the page has not been written - to the cache, and that either there's a block containing the old data or - no block at all in the cache. - - end_io_func() might be called in interrupt context. - -Else if there's no space available in the cache, -ENOBUFS will be returned. - - -MULTIPLE PAGE READ ------------------- - -A facility is provided to read several pages at once, as requested by the -readpages() address space operation: - - int fscache_read_or_alloc_pages(struct fscache_cookie *cookie, - struct address_space *mapping, - struct list_head *pages, - int *nr_pages, - fscache_rw_complete_t end_io_func, - void *context, - gfp_t gfp); - -This works in a similar way to fscache_read_or_alloc_page(), except: - - (1) Any page it can retrieve data for is removed from pages and nr_pages and - dispatched for reading to the disk. Reads of adjacent pages on disk may - be merged for greater efficiency. - - (2) The mark_pages_cached() cookie operation will be called on several pages - at once if they're being read or allocated. - - (3) If there was an general error, then that error will be returned. - - Else if some pages couldn't be allocated or read, then -ENOBUFS will be - returned. - - Else if some pages couldn't be read but were allocated, then -ENODATA will - be returned. - - Otherwise, if all pages had reads dispatched, then 0 will be returned, the - list will be empty and *nr_pages will be 0. - - (4) end_io_func will be called once for each page being read as the reads - complete. It will be called in process context if error != 0, but it may - be called in interrupt context if there is no error. - -Note that a return of -ENODATA, -ENOBUFS or any other error does not preclude -some of the pages being read and some being allocated. Those pages will have -been marked appropriately and will need uncaching. - - -============== -PAGE UNCACHING -============== - -To uncache a page, this function should be called: - - void fscache_uncache_page(struct fscache_cookie *cookie, - struct page *page); - -This function permits the cache to release any in-memory representation it -might be holding for this netfs page. This function must be called once for -each page on which the read or write page functions above have been called to -make sure the cache's in-memory tracking information gets torn down. - -Note that pages can't be explicitly deleted from the a data file. The whole -data file must be retired (see the relinquish cookie function below). - -Furthermore, note that this does not cancel the asynchronous read or write -operation started by the read/alloc and write functions. - -There is another unbinding operation similar to the above that takes a set of -pages to unbind in one go: - - void fscache_uncache_pagevec(struct fscache_cookie *cookie, - struct pagevec *pagevec); - - -========================== -INDEX AND DATA FILE UPDATE -========================== - -To request an update of the index data for an index or other object, the -following function should be called: - - void fscache_update_cookie(struct fscache_cookie *cookie); - -This function will refer back to the netfs_data pointer stored in the cookie by -the acquisition function to obtain the data to write into each revised index -entry. The update method in the parent index definition will be called to -transfer the data. - -Note that partial updates may happen automatically at other times, such as when -data blocks are added to a data file object. - - -=============================== -MISCELLANEOUS COOKIE OPERATIONS -=============================== - -There are a number of operations that can be used to control cookies: - - (*) Cookie pinning: - - int fscache_pin_cookie(struct fscache_cookie *cookie); - void fscache_unpin_cookie(struct fscache_cookie *cookie); - - These operations permit data cookies to be pinned into the cache and to - have the pinning removed. They are not permitted on index cookies. - - The pinning function will return 0 if successful, -ENOBUFS in the cookie - isn't backed by a cache, -EOPNOTSUPP if the cache doesn't support pinning, - -ENOSPC if there isn't enough space to honour the operation, -ENOMEM or - -EIO if there's any other problem. - - (*) Data space reservation: - - int fscache_reserve_space(struct fscache_cookie *cookie, loff_t size); - - This permits a netfs to request cache space be reserved to store up to the - given amount of a file. It is permitted to ask for more than the current - size of the file to allow for future file expansion. - - If size is given as zero then the reservation will be cancelled. - - The function will return 0 if successful, -ENOBUFS in the cookie isn't - backed by a cache, -EOPNOTSUPP if the cache doesn't support reservations, - -ENOSPC if there isn't enough space to honour the operation, -ENOMEM or - -EIO if there's any other problem. - - Note that this doesn't pin an object in a cache; it can still be culled to - make space if it's not in use. - - -===================== -COOKIE UNREGISTRATION -===================== - -To get rid of a cookie, this function should be called. - - void fscache_relinquish_cookie(struct fscache_cookie *cookie, - int retire); - -If retire is non-zero, then the object will be marked for recycling, and all -copies of it will be removed from all active caches in which it is present. -Not only that but all child objects will also be retired. - -If retire is zero, then the object may be available again when next the -acquisition function is called. Retirement here will overrule the pinning on a -cookie. - -One very important note - relinquish must NOT be called for a cookie unless all -the cookies for "child" indices, objects and pages have been relinquished -first. - - -================================ -INDEX AND DATA FILE INVALIDATION -================================ - -There is no direct way to invalidate an index subtree or a data file. To do -this, the caller should relinquish and retire the cookie they have, and then -acquire a new one. diff --git a/Documentation/filesystems/relay.txt b/Documentation/filesystems/relay.txt deleted file mode 100644 index d6788dae0..000000000 --- a/Documentation/filesystems/relay.txt +++ /dev/null @@ -1,479 +0,0 @@ -relay interface (formerly relayfs) -================================== - -The relay interface provides a means for kernel applications to -efficiently log and transfer large quantities of data from the kernel -to userspace via user-defined 'relay channels'. - -A 'relay channel' is a kernel->user data relay mechanism implemented -as a set of per-cpu kernel buffers ('channel buffers'), each -represented as a regular file ('relay file') in user space. Kernel -clients write into the channel buffers using efficient write -functions; these automatically log into the current cpu's channel -buffer. User space applications mmap() or read() from the relay files -and retrieve the data as it becomes available. The relay files -themselves are files created in a host filesystem, e.g. debugfs, and -are associated with the channel buffers using the API described below. - -The format of the data logged into the channel buffers is completely -up to the kernel client; the relay interface does however provide -hooks which allow kernel clients to impose some structure on the -buffer data. The relay interface doesn't implement any form of data -filtering - this also is left to the kernel client. The purpose is to -keep things as simple as possible. - -This document provides an overview of the relay interface API. The -details of the function parameters are documented along with the -functions in the relay interface code - please see that for details. - -Semantics -========= - -Each relay channel has one buffer per CPU, each buffer has one or more -sub-buffers. Messages are written to the first sub-buffer until it is -too full to contain a new message, in which case it it is written to -the next (if available). Messages are never split across sub-buffers. -At this point, userspace can be notified so it empties the first -sub-buffer, while the kernel continues writing to the next. - -When notified that a sub-buffer is full, the kernel knows how many -bytes of it are padding i.e. unused space occurring because a complete -message couldn't fit into a sub-buffer. Userspace can use this -knowledge to copy only valid data. - -After copying it, userspace can notify the kernel that a sub-buffer -has been consumed. - -A relay channel can operate in a mode where it will overwrite data not -yet collected by userspace, and not wait for it to be consumed. - -The relay channel itself does not provide for communication of such -data between userspace and kernel, allowing the kernel side to remain -simple and not impose a single interface on userspace. It does -provide a set of examples and a separate helper though, described -below. - -The read() interface both removes padding and internally consumes the -read sub-buffers; thus in cases where read(2) is being used to drain -the channel buffers, special-purpose communication between kernel and -user isn't necessary for basic operation. - -One of the major goals of the relay interface is to provide a low -overhead mechanism for conveying kernel data to userspace. While the -read() interface is easy to use, it's not as efficient as the mmap() -approach; the example code attempts to make the tradeoff between the -two approaches as small as possible. - -klog and relay-apps example code -================================ - -The relay interface itself is ready to use, but to make things easier, -a couple simple utility functions and a set of examples are provided. - -The relay-apps example tarball, available on the relay sourceforge -site, contains a set of self-contained examples, each consisting of a -pair of .c files containing boilerplate code for each of the user and -kernel sides of a relay application. When combined these two sets of -boilerplate code provide glue to easily stream data to disk, without -having to bother with mundane housekeeping chores. - -The 'klog debugging functions' patch (klog.patch in the relay-apps -tarball) provides a couple of high-level logging functions to the -kernel which allow writing formatted text or raw data to a channel, -regardless of whether a channel to write into exists or not, or even -whether the relay interface is compiled into the kernel or not. These -functions allow you to put unconditional 'trace' statements anywhere -in the kernel or kernel modules; only when there is a 'klog handler' -registered will data actually be logged (see the klog and kleak -examples for details). - -It is of course possible to use the relay interface from scratch, -i.e. without using any of the relay-apps example code or klog, but -you'll have to implement communication between userspace and kernel, -allowing both to convey the state of buffers (full, empty, amount of -padding). The read() interface both removes padding and internally -consumes the read sub-buffers; thus in cases where read(2) is being -used to drain the channel buffers, special-purpose communication -between kernel and user isn't necessary for basic operation. Things -such as buffer-full conditions would still need to be communicated via -some channel though. - -klog and the relay-apps examples can be found in the relay-apps -tarball on http://relayfs.sourceforge.net - -The relay interface user space API -================================== - -The relay interface implements basic file operations for user space -access to relay channel buffer data. Here are the file operations -that are available and some comments regarding their behavior: - -open() enables user to open an _existing_ channel buffer. - -mmap() results in channel buffer being mapped into the caller's - memory space. Note that you can't do a partial mmap - you - must map the entire file, which is NRBUF * SUBBUFSIZE. - -read() read the contents of a channel buffer. The bytes read are - 'consumed' by the reader, i.e. they won't be available - again to subsequent reads. If the channel is being used - in no-overwrite mode (the default), it can be read at any - time even if there's an active kernel writer. If the - channel is being used in overwrite mode and there are - active channel writers, results may be unpredictable - - users should make sure that all logging to the channel has - ended before using read() with overwrite mode. Sub-buffer - padding is automatically removed and will not be seen by - the reader. - -sendfile() transfer data from a channel buffer to an output file - descriptor. Sub-buffer padding is automatically removed - and will not be seen by the reader. - -poll() POLLIN/POLLRDNORM/POLLERR supported. User applications are - notified when sub-buffer boundaries are crossed. - -close() decrements the channel buffer's refcount. When the refcount - reaches 0, i.e. when no process or kernel client has the - buffer open, the channel buffer is freed. - -In order for a user application to make use of relay files, the -host filesystem must be mounted. For example, - - mount -t debugfs debugfs /debug - -NOTE: the host filesystem doesn't need to be mounted for kernel - clients to create or use channels - it only needs to be - mounted when user space applications need access to the buffer - data. - - -The relay interface kernel API -============================== - -Here's a summary of the API the relay interface provides to in-kernel clients: - -TBD(curr. line MT:/API/) - channel management functions: - - relay_open(base_filename, parent, subbuf_size, n_subbufs, - callbacks) - relay_close(chan) - relay_flush(chan) - relay_reset(chan) - - channel management typically called on instigation of userspace: - - relay_subbufs_consumed(chan, cpu, subbufs_consumed) - - write functions: - - relay_write(chan, data, length) - __relay_write(chan, data, length) - relay_reserve(chan, length) - - callbacks: - - subbuf_start(buf, subbuf, prev_subbuf, prev_padding) - buf_mapped(buf, filp) - buf_unmapped(buf, filp) - create_buf_file(filename, parent, mode, buf, is_global) - remove_buf_file(dentry) - - helper functions: - - relay_buf_full(buf) - subbuf_start_reserve(buf, length) - - -Creating a channel ------------------- - -relay_open() is used to create a channel, along with its per-cpu -channel buffers. Each channel buffer will have an associated file -created for it in the host filesystem, which can be and mmapped or -read from in user space. The files are named basename0...basenameN-1 -where N is the number of online cpus, and by default will be created -in the root of the filesystem (if the parent param is NULL). If you -want a directory structure to contain your relay files, you should -create it using the host filesystem's directory creation function, -e.g. debugfs_create_dir(), and pass the parent directory to -relay_open(). Users are responsible for cleaning up any directory -structure they create, when the channel is closed - again the host -filesystem's directory removal functions should be used for that, -e.g. debugfs_remove(). - -In order for a channel to be created and the host filesystem's files -associated with its channel buffers, the user must provide definitions -for two callback functions, create_buf_file() and remove_buf_file(). -create_buf_file() is called once for each per-cpu buffer from -relay_open() and allows the user to create the file which will be used -to represent the corresponding channel buffer. The callback should -return the dentry of the file created to represent the channel buffer. -remove_buf_file() must also be defined; it's responsible for deleting -the file(s) created in create_buf_file() and is called during -relay_close(). - -Here are some typical definitions for these callbacks, in this case -using debugfs: - -/* - * create_buf_file() callback. Creates relay file in debugfs. - */ -static struct dentry *create_buf_file_handler(const char *filename, - struct dentry *parent, - int mode, - struct rchan_buf *buf, - int *is_global) -{ - return debugfs_create_file(filename, mode, parent, buf, - &relay_file_operations); -} - -/* - * remove_buf_file() callback. Removes relay file from debugfs. - */ -static int remove_buf_file_handler(struct dentry *dentry) -{ - debugfs_remove(dentry); - - return 0; -} - -/* - * relay interface callbacks - */ -static struct rchan_callbacks relay_callbacks = -{ - .create_buf_file = create_buf_file_handler, - .remove_buf_file = remove_buf_file_handler, -}; - -And an example relay_open() invocation using them: - - chan = relay_open("cpu", NULL, SUBBUF_SIZE, N_SUBBUFS, &relay_callbacks); - -If the create_buf_file() callback fails, or isn't defined, channel -creation and thus relay_open() will fail. - -The total size of each per-cpu buffer is calculated by multiplying the -number of sub-buffers by the sub-buffer size passed into relay_open(). -The idea behind sub-buffers is that they're basically an extension of -double-buffering to N buffers, and they also allow applications to -easily implement random-access-on-buffer-boundary schemes, which can -be important for some high-volume applications. The number and size -of sub-buffers is completely dependent on the application and even for -the same application, different conditions will warrant different -values for these parameters at different times. Typically, the right -values to use are best decided after some experimentation; in general, -though, it's safe to assume that having only 1 sub-buffer is a bad -idea - you're guaranteed to either overwrite data or lose events -depending on the channel mode being used. - -The create_buf_file() implementation can also be defined in such a way -as to allow the creation of a single 'global' buffer instead of the -default per-cpu set. This can be useful for applications interested -mainly in seeing the relative ordering of system-wide events without -the need to bother with saving explicit timestamps for the purpose of -merging/sorting per-cpu files in a postprocessing step. - -To have relay_open() create a global buffer, the create_buf_file() -implementation should set the value of the is_global outparam to a -non-zero value in addition to creating the file that will be used to -represent the single buffer. In the case of a global buffer, -create_buf_file() and remove_buf_file() will be called only once. The -normal channel-writing functions, e.g. relay_write(), can still be -used - writes from any cpu will transparently end up in the global -buffer - but since it is a global buffer, callers should make sure -they use the proper locking for such a buffer, either by wrapping -writes in a spinlock, or by copying a write function from relay.h and -creating a local version that internally does the proper locking. - -Channel 'modes' ---------------- - -relay channels can be used in either of two modes - 'overwrite' or -'no-overwrite'. The mode is entirely determined by the implementation -of the subbuf_start() callback, as described below. The default if no -subbuf_start() callback is defined is 'no-overwrite' mode. If the -default mode suits your needs, and you plan to use the read() -interface to retrieve channel data, you can ignore the details of this -section, as it pertains mainly to mmap() implementations. - -In 'overwrite' mode, also known as 'flight recorder' mode, writes -continuously cycle around the buffer and will never fail, but will -unconditionally overwrite old data regardless of whether it's actually -been consumed. In no-overwrite mode, writes will fail, i.e. data will -be lost, if the number of unconsumed sub-buffers equals the total -number of sub-buffers in the channel. It should be clear that if -there is no consumer or if the consumer can't consume sub-buffers fast -enough, data will be lost in either case; the only difference is -whether data is lost from the beginning or the end of a buffer. - -As explained above, a relay channel is made of up one or more -per-cpu channel buffers, each implemented as a circular buffer -subdivided into one or more sub-buffers. Messages are written into -the current sub-buffer of the channel's current per-cpu buffer via the -write functions described below. Whenever a message can't fit into -the current sub-buffer, because there's no room left for it, the -client is notified via the subbuf_start() callback that a switch to a -new sub-buffer is about to occur. The client uses this callback to 1) -initialize the next sub-buffer if appropriate 2) finalize the previous -sub-buffer if appropriate and 3) return a boolean value indicating -whether or not to actually move on to the next sub-buffer. - -To implement 'no-overwrite' mode, the userspace client would provide -an implementation of the subbuf_start() callback something like the -following: - -static int subbuf_start(struct rchan_buf *buf, - void *subbuf, - void *prev_subbuf, - unsigned int prev_padding) -{ - if (prev_subbuf) - *((unsigned *)prev_subbuf) = prev_padding; - - if (relay_buf_full(buf)) - return 0; - - subbuf_start_reserve(buf, sizeof(unsigned int)); - - return 1; -} - -If the current buffer is full, i.e. all sub-buffers remain unconsumed, -the callback returns 0 to indicate that the buffer switch should not -occur yet, i.e. until the consumer has had a chance to read the -current set of ready sub-buffers. For the relay_buf_full() function -to make sense, the consumer is reponsible for notifying the relay -interface when sub-buffers have been consumed via -relay_subbufs_consumed(). Any subsequent attempts to write into the -buffer will again invoke the subbuf_start() callback with the same -parameters; only when the consumer has consumed one or more of the -ready sub-buffers will relay_buf_full() return 0, in which case the -buffer switch can continue. - -The implementation of the subbuf_start() callback for 'overwrite' mode -would be very similar: - -static int subbuf_start(struct rchan_buf *buf, - void *subbuf, - void *prev_subbuf, - unsigned int prev_padding) -{ - if (prev_subbuf) - *((unsigned *)prev_subbuf) = prev_padding; - - subbuf_start_reserve(buf, sizeof(unsigned int)); - - return 1; -} - -In this case, the relay_buf_full() check is meaningless and the -callback always returns 1, causing the buffer switch to occur -unconditionally. It's also meaningless for the client to use the -relay_subbufs_consumed() function in this mode, as it's never -consulted. - -The default subbuf_start() implementation, used if the client doesn't -define any callbacks, or doesn't define the subbuf_start() callback, -implements the simplest possible 'no-overwrite' mode, i.e. it does -nothing but return 0. - -Header information can be reserved at the beginning of each sub-buffer -by calling the subbuf_start_reserve() helper function from within the -subbuf_start() callback. This reserved area can be used to store -whatever information the client wants. In the example above, room is -reserved in each sub-buffer to store the padding count for that -sub-buffer. This is filled in for the previous sub-buffer in the -subbuf_start() implementation; the padding value for the previous -sub-buffer is passed into the subbuf_start() callback along with a -pointer to the previous sub-buffer, since the padding value isn't -known until a sub-buffer is filled. The subbuf_start() callback is -also called for the first sub-buffer when the channel is opened, to -give the client a chance to reserve space in it. In this case the -previous sub-buffer pointer passed into the callback will be NULL, so -the client should check the value of the prev_subbuf pointer before -writing into the previous sub-buffer. - -Writing to a channel --------------------- - -Kernel clients write data into the current cpu's channel buffer using -relay_write() or __relay_write(). relay_write() is the main logging -function - it uses local_irqsave() to protect the buffer and should be -used if you might be logging from interrupt context. If you know -you'll never be logging from interrupt context, you can use -__relay_write(), which only disables preemption. These functions -don't return a value, so you can't determine whether or not they -failed - the assumption is that you wouldn't want to check a return -value in the fast logging path anyway, and that they'll always succeed -unless the buffer is full and no-overwrite mode is being used, in -which case you can detect a failed write in the subbuf_start() -callback by calling the relay_buf_full() helper function. - -relay_reserve() is used to reserve a slot in a channel buffer which -can be written to later. This would typically be used in applications -that need to write directly into a channel buffer without having to -stage data in a temporary buffer beforehand. Because the actual write -may not happen immediately after the slot is reserved, applications -using relay_reserve() can keep a count of the number of bytes actually -written, either in space reserved in the sub-buffers themselves or as -a separate array. See the 'reserve' example in the relay-apps tarball -at http://relayfs.sourceforge.net for an example of how this can be -done. Because the write is under control of the client and is -separated from the reserve, relay_reserve() doesn't protect the buffer -at all - it's up to the client to provide the appropriate -synchronization when using relay_reserve(). - -Closing a channel ------------------ - -The client calls relay_close() when it's finished using the channel. -The channel and its associated buffers are destroyed when there are no -longer any references to any of the channel buffers. relay_flush() -forces a sub-buffer switch on all the channel buffers, and can be used -to finalize and process the last sub-buffers before the channel is -closed. - -Misc ----- - -Some applications may want to keep a channel around and re-use it -rather than open and close a new channel for each use. relay_reset() -can be used for this purpose - it resets a channel to its initial -state without reallocating channel buffer memory or destroying -existing mappings. It should however only be called when it's safe to -do so, i.e. when the channel isn't currently being written to. - -Finally, there are a couple of utility callbacks that can be used for -different purposes. buf_mapped() is called whenever a channel buffer -is mmapped from user space and buf_unmapped() is called when it's -unmapped. The client can use this notification to trigger actions -within the kernel application, such as enabling/disabling logging to -the channel. - - -Resources -========= - -For news, example code, mailing list, etc. see the relay interface homepage: - - http://relayfs.sourceforge.net - - -Credits -======= - -The ideas and specs for the relay interface came about as a result of -discussions on tracing involving the following: - -Michel Dagenais -Richard Moore -Bob Wisniewski -Karim Yaghmour -Tom Zanussi - -Also thanks to Hubertus Franke for a lot of useful suggestions and bug -reports. diff --git a/Documentation/filesystems/umsdos.txt b/Documentation/filesystems/umsdos.txt deleted file mode 100644 index c253708f3..000000000 --- a/Documentation/filesystems/umsdos.txt +++ /dev/null @@ -1,100 +0,0 @@ -Firstly, let me say that UMSDOS is going through some major code changes, -and has some KNOWN BUGS (and quite a few unknown :-).

The first addressing -level we will call banks. A bank holds data for one or more sensors. The data -in a bank for a sensor is one or more bytes large. - -The number of bytes is fixed for a given bank, you should always read or write -that many bytes, reading / writing more will fail, the results when writing -less then the number of bytes for a given bank are undetermined. - -See below for all known bank addresses, numbers of sensors in that bank, -number of bytes data per sensor and contents/meaning of those bytes. - -Although both this document and the kernel driver have kept the sensor -terminoligy for the addressing within a bank this is not 100% correct, in -bank 0x24 for example the addressing within the bank selects a PWM output not -a sensor. - -Notice that some banks have both a read and a write address this is how the -uGuru determines if a read from or a write to the bank is taking place, thus -when reading you should always use the read address and when writing the -write address. The write address is always one (1) more then the read address. - - -uGuru ready ------------ - -Before you can read from or write to the uGuru you must first put the uGuru -in "ready" mode. - -To put the uGuru in ready mode first write 0x00 to DATA and then wait for DATA -to hold 0x09, DATA should read 0x09 within 250 read cycles. - -Next CMD _must_ be read and should hold 0xAC, usually CMD will hold 0xAC the -first read but sometimes it takes a while before CMD holds 0xAC and thus it -has to be read a number of times (max 50). - -After reading CMD, DATA should hold 0x08 which means that the uGuru is ready -for input. As above DATA will usually hold 0x08 the first read but not always. -This step can be skipped, but it is undetermined what happens if the uGuru has -not yet reported 0x08 at DATA and you proceed with writing a bank address. - - -Sending bank and sensor addresses to the uGuru ----------------------------------------------- - -First the uGuru must be in "ready" mode as described above, DATA should hold -0x08 indicating that the uGuru wants input, in this case the bank address. - -Next write the bank address to DATA. After the bank address has been written -wait for to DATA to hold 0x08 again indicating that it wants / is ready for -more input (max 250 reads). - -Once DATA holds 0x08 again write the sensor address to CMD. - - -Reading -------- - -First send the bank and sensor addresses as described above. -Then for each byte of data you want to read wait for DATA to hold 0x01 -which indicates that the uGuru is ready to be read (max 250 reads) and once -DATA holds 0x01 read the byte from CMD. - -Once all bytes have been read data will hold 0x09, but there is no reason to -test for this.

If you see {driver_name}, replace -that with the respective name of the driver, such as saa7110.c , {driver_name} -= saa7110. - -------------------------------------------------------- - -Step 1: Include the right header file - -Perform the following change within the driver - -#include --> #include - -Step 2: Add and set the i2c modes - -Add the following code near the top of the driver - -static unsigned short normal_i2c[] = {34>>1, I2C_CLIENT_END }; -static unsigned short normal_i2c_range[] = { I2C_CLIENT_END }; -static unsigned short probe[2] = { I2C_CLIENT_END , I2C_CLIENT_END }; -static unsigned short probe_range[2] = { I2C_CLIENT_END , I2C_CLIENT_END }; -static unsigned short ignore[2] = { I2C_CLIENT_END , I2C_CLIENT_END }; -static unsigned short ignore_range[2] = { I2C_CLIENT_END, I2C_CLIENT_END }; -static unsigned short force[2] = { I2C_CLIENT_END , I2C_CLIENT_END }; - -static struct i2c_client_address_data addr_data = { - normal_i2c , normal_i2c_range, - probe , probe_range, - ignore , ignore_range, - force -}; - -static struct i2c_client client_template; - -Step 3: Modify the driver info struct - -Within the struct for the driver , such as struct {driver_name} , make the -following change , -struct i2c_bus *bus --> struct i2c_client *client - -Make changes where this change affects references within the file. - -Add a semaphore to the driver struct (as above) - -struct semaphore lock - -Step 5: Remove specific read and write functions - -Remove the driver specific write and read functions, usually in the form: -{driver_name}_write , {driver_name}_read , {driver_name}_write_block , etc. - -Step 6: Update the write and read functions for the current I2C API - -Replace all references of {driver_name}_write with i2c_smbus_write_byte_data -Replace all references of {driver_name}_read with i2c_smbus_read_byte_data or -i2c_smbus_read_byte , depending on args passed in. - -** Ensure that these functions pass in the i2c_client *client , NOT the -decoder/encoder that was passed in the driver specific write and read -functions. - -Step 7: Modify the driver's attach function - -Change the driver attach function prototype : -{driver_name}_attach(struct i2c_device *device) --> {driver_name}_attach(struct -i2c_adapter *adap, int addr , unsigned short flags, int kind) - -Create a i2c_client client... -Add the following (where "decoder" is a reference to a struct for the driver -info: - -struct i2c_client *client; -client = kmalloc(sizeof(*client), GFP_KERNEL); -if(client == NULL) - return -ENOMEM; -client_template.adapter = adap; -client_template.addr = addr; -memcpy(client, &client_template, sizeof(*client)); -strcpy(client->name , "{driver_name}"); -decoder->client = client; -client->data = decoder; -decoder->addr = addr; - -Towards the end of the function, add: - -init_MUTEX(&decoder->lock); -i2c_attach_client(client); - - -Step 8: Modify the driver's detach function - -Change the driver detach function prototype : -{driver_name}_detach(struct i2c_device *device) --> {driver_name}_detach(struct -i2c_client *client) - -In the beginning of the detach function, add: -i2c_detach_client(client); - -Towards the end of the detach function, add: -kfree(client->data); -kfree(client); - -Step 9: Modify the driver's command function - -Change the driver command function prototype : - -Step 10: Add the probe function after the driver's attach function. - -Add the following code: - -static int {driver_name}_probe(struct i2c_adapter *adap) -{ - return i2c_probe(adap, &addr_data, {driver_name}_attach); - -} - -Step 11: Modify the driver's i2c_driver - -Find the i2c_driver , such as -static struct i2c_driver i2c_driver_saa7110 -It is usually located towards the end of the driver -Replace the values from I2C_DRIVERID_{something} to {driver_name}_attach, and -add the following -I2C_DRIVERID_{driver_name} , // verify by looking in include/linux/i2c-id.h -I2C_DF_NOTIFY, -{driver_name}_probe, -.... - -Step 12: Adding the i2c_client - -Add the i2c_client to the driver. Add the following code: - -static struct i2c_client client_template = { - "{driver_name}_client", - -1, - 0, - 0, - NULL, - {i2c_driver reference} -}; - -Step 13: Registering and Unregistering - -Replace i2c_register_driver with i2c_add_driver -Replace i2c_unregister_driver with i2c_del_driver - -------------------------------------------------------- - -Example: - -The following patch provides the i2c coversion patch for the saa7110 driver -based on the above guide (for clarity). - - ---- drivers/media/video/saa7110.c.old Fri Jun 28 10:22:52 2002 -+++ drivers/media/video/saa7110.c Thu Jul 4 16:51:08 2002 -@@ -26,7 +26,7 @@ - #include - #include - --#include -+#include - #include - #include "linux/video_decoder.h" - -@@ -37,13 +37,31 @@ - - #define I2C_SAA7110 0x9C /* or 0x9E */ - -+#define IF_NAME "saa7110" - #define I2C_DELAY 10 /* 10 us or 100khz */ - -+static unsigned short normal_i2c[] = {34>>1, I2C_CLIENT_END };

The UC attribute is - used for memory-mapped I/O devices. The WC attribute is uncacheable - like UC is, but writes may be delayed and combined to increase - performance for things like frame buffers. - - The Itanium architecture requires that we avoid accessing the same - page with both a cacheable mapping and an uncacheable mapping[1]. - - The design of the chipset determines which attributes are supported - on which regions of the address space.

At boot-time, the kernel uses - the EFI GetMemoryMap() interface. ACPI can also describe memory - devices and the attributes they support, but Linux/ia64 currently - doesn't use this information. - - The kernel uses the efi_memmap table returned from GetMemoryMap() to - learn the attributes supported by each region of physical address - space. Unfortunately, this table does not completely describe the - address space because some machines omit some or all of the MMIO - regions from the map. - - The kernel maintains another table, kern_memmap, which describes the - memory Linux is actually using and the attribute for each region. - This contains only system memory; it does not contain MMIO space. - - The kern_memmap table typically contains only a subset of the system - memory described by the efi_memmap. Linux/ia64 can't use all memory - in the system because of constraints imposed by the identity mapping - scheme. - - The efi_memmap table is preserved unmodified because the original - boot-time information is required for kexec. - -KERNEL IDENTITY MAPPINGS - - Linux/ia64 identity mappings are done with large pages, currently - either 16MB or 64MB, referred to as "granules." Cacheable mappings - are speculative[2], so the processor can read any location in the - page at any time, independent of the programmer's intentions. This - means that to avoid attribute aliasing, Linux can create a cacheable - identity mapping only when the entire granule supports cacheable - access. - - Therefore, kern_memmap contains only full granule-sized regions that - can referenced safely by an identity mapping. - - Uncacheable mappings are not speculative, so the processor will - generate UC accesses only to locations explicitly referenced by - software. This allows UC identity mappings to cover granules that - are only partially populated, or populated with a combination of UC - and WB regions. - -USER MAPPINGS - - User mappings are typically done with 16K or 64K pages. The smaller - page size allows more flexibility because only 16K or 64K has to be - homogeneous with respect to memory attributes. - -POTENTIAL ATTRIBUTE ALIASING CASES - - There are several ways the kernel creates new mappings: - - mmap of /dev/mem - - This uses remap_pfn_range(), which creates user mappings. These - mappings may be either WB or UC. If the region being mapped - happens to be in kern_memmap, meaning that it may also be mapped - by a kernel identity mapping, the user mapping must use the same - attribute as the kernel mapping. - - If the region is not in kern_memmap, the user mapping should use - an attribute reported as being supported in the EFI memory map. - - Since the EFI memory map does not describe MMIO on some - machines, this should use an uncacheable mapping as a fallback. - - mmap of /sys/class/pci_bus/.../legacy_mem - - This is very similar to mmap of /dev/mem, except that legacy_mem - only allows mmap of the one megabyte "legacy MMIO" area for a - specific PCI bus. Typically this is the first megabyte of - physical address space, but it may be different on machines with - several VGA devices. - - "X" uses this to access VGA frame buffers. Using legacy_mem - rather than /dev/mem allows multiple instances of X to talk to - different VGA cards. - - The /dev/mem mmap constraints apply. - - However, since this is for mapping legacy MMIO space, WB access - does not make sense. This matters on machines without legacy - VGA support: these machines may have WB memory for the entire - first megabyte (or even the entire first granule). - - On these machines, we could mmap legacy_mem as WB, which would - be safe in terms of attribute aliasing, but X has no way of - knowing that it is accessing regular memory, not a frame buffer, - so the kernel should fail the mmap rather than doing it with WB. - - read/write of /dev/mem - - This uses copy_from_user(), which implicitly uses a kernel - identity mapping. This is obviously safe for things in - kern_memmap. - - There may be corner cases of things that are not in kern_memmap, - but could be accessed this way. For example, registers in MMIO - space are not in kern_memmap, but could be accessed with a UC - mapping. This would not cause attribute aliasing. But - registers typically can be accessed only with four-byte or - eight-byte accesses, and the copy_from_user() path doesn't allow - any control over the access size, so this would be dangerous. - - ioremap() - - This returns a kernel identity mapping for use inside the - kernel. - - If the region is in kern_memmap, we should use the attribute - specified there. Otherwise, if the EFI memory map reports that - the entire granule supports WB, we should use that (granules - that are partially reserved or occupied by firmware do not appear - in kern_memmap). Otherwise, we should use a UC mapping. - -PAST PROBLEM CASES - - mmap of various MMIO regions from /dev/mem by "X" on Intel platforms - - The EFI memory map may not report these MMIO regions. - - These must be allowed so that X will work. This means that - when the EFI memory map is incomplete, every /dev/mem mmap must - succeed. It may create either WB or UC user mappings, depending - on whether the region is in kern_memmap or the EFI memory map. - - mmap of 0x0-0xA0000 /dev/mem by "hwinfo" on HP sx1000 with VGA enabled - - See https://bugzilla.novell.com/show_bug.cgi?id=140858. - - The EFI memory map reports the following attributes: - 0x00000-0x9FFFF WB only - 0xA0000-0xBFFFF UC only (VGA frame buffer) - 0xC0000-0xFFFFF WB only - - This mmap is done with user pages, not kernel identity mappings, - so it is safe to use WB mappings. - - The kernel VGA driver may ioremap the VGA frame buffer at 0xA0000, - which will use a granule-sized UC mapping covering 0-0xFFFFF. This - granule covers some WB-only memory, but since UC is non-speculative, - the processor will never generate an uncacheable reference to the - WB-only areas unless the driver explicitly touches them. - - mmap of 0x0-0xFFFFF legacy_mem by "X" - - If the EFI memory map reports this entire range as WB, there - is no VGA MMIO hole, and the mmap should fail or be done with - a WB mapping. - - There's no easy way for X to determine whether the 0xA0000-0xBFFFF - region is a frame buffer or just memory, so I think it's best to - just fail this mmap request rather than using a WB mapping. As - far as I know, there's no need to map legacy_mem with WB - mappings. - - Otherwise, a UC mapping of the entire region is probably safe. - The VGA hole means the region will not be in kern_memmap.

Requirements - ------------ -1.1. Hardware - -------- - This release supports the connection of the Gigaset 307x/417x family of - ISDN DECT bases via Gigaset M101 Data, Gigaset M105 Data or direct USB - connection. The following devices are reported to be compatible: - 307x/417x: - Gigaset SX255isdn - Gigaset SX353isdn - Sinus 45 [AB] isdn (Deutsche Telekom) - Sinus 721X/XA - Vox Chicago 390 ISDN (KPN Telecom) - M101: - Sinus 45 Data 1 (Telekom) - M105: - Gigaset USB Adapter DECT - Sinus 45 Data 2 (Telekom) - Sinus 721 data - Chicago 390 USB (KPN) - See also http://www.erbze.info/sinus_gigaset.htm and - http://gigaset307x.sourceforge.net/ - - We had also reports from users of Gigaset M105 who could use the drivers - with SX 100 and CX 100 ISDN bases (only in unimodem mode, see section 2.4.) - If you have another device that works with our driver, please let us know. - For example, Gigaset SX205isdn/Sinus 721 X SE and Gigaset SX303isdn bases - are just versions without answering machine of models known to work, so - they should work just as well; but so far we are lacking positive reports - on these. - - Chances of getting an USB device to work are good if the output of - lsusb - at the command line contains one of the following: - ID 0681:0001 - ID 0681:0002 - ID 0681:0009 - ID 0681:0021 - ID 0681:0022 - -1.2. Software - -------- - The driver works with ISDN4linux and so can be used with any software - which is able to use ISDN4linux for ISDN connections (voice or data). - CAPI4Linux support is planned but not yet available. - - There are some user space tools available at - http://sourceforge.net/projects/gigaset307x/ - which provide access to additional device specific functions like SMS, - phonebook or call journal. - - -2. How to use the driver - --------------------- -2.1. Modules - ------- - To get the device working, you have to load the proper kernel module. You - can do this using - modprobe modulename - where modulename is usb_gigaset (M105) or bas_gigaset (direct USB - connection to the base). - -2.2. Device nodes for user space programs - ------------------------------------ - The device can be accessed from user space (eg. by the user space tools - mentioned in 1.2.) through the device nodes: - - - /dev/ttyGU0 for M105 (USB data boxes) - - /dev/ttyGB0 for the base driver (direct USB connection) - - You can also select a "default device" which is used by the frontends when - no device node is given as parameter, by creating a symlink /dev/ttyG to - one of them, eg.: - - ln -s /dev/ttyGB0 /dev/ttyG - -2.3. ISDN4linux - ---------- - This is the "normal" mode of operation. After loading the module you can - set up the ISDN system just as you'd do with any ISDN card. - Your distribution should provide some configuration utility. - If not, you can use some HOWTOs like - http://www.linuxhaven.de/dlhp/HOWTO/DE-ISDN-HOWTO-5.html - If this doesn't work, because you have some recent device like SX100 where - debug output (see section 3.2.) shows something like this when dialing - CMD Received: ERROR - Available Params: 0 - Connection State: 0, Response: -1 - gigaset_process_response: resp_code -1 in ConState 0 ! - Timeout occurred - you might need to use unimodem mode: - -2.4. Unimodem mode - ------------- - This is needed for some devices [e.g. SX100] as they have problems with - the "normal" commands. - - If you have installed the command line tool gigacontr, you can enter - unimodem mode using - gigacontr --mode unimodem - You can switch back using - gigacontr --mode isdn - - You can also load the driver using e.g. - modprobe usb_gigaset startmode=0 - to prevent the driver from starting in "isdn4linux mode". - - In this mode the device works like a modem connected to a serial port - (the /dev/ttyGU0, ... mentioned above) which understands the commands - ATZ init, reset - => OK or ERROR - ATD - ATDT dial - => OK, CONNECT, - BUSY, - NO DIAL TONE, - NO CARRIER, - NO ANSWER - +++ change to command mode when connected - ATH hangup - - You can use some configuration tool of your distribution to configure this - "modem" or configure pppd/wvdial manually. There are some example ppp - configuration files and chat scripts in the gigaset-VERSION/ppp directory - in the driver packages from http://sourceforge.net/projects/gigaset307x/. - Please note that the USB drivers are not able to change the state of the - control lines (the M105 driver can be configured to use some undocumented - control requests, if you really need the control lines, though). This means - you must use "Stupid Mode" if you are using wvdial or you should use the - nocrtscts option of pppd. - You must also assure that the ppp_async module is loaded with the parameter - flag_time=0. You can do this e.g. by adding a line like - - options ppp_async flag_time=0 - - to /etc/modprobe.conf. If your distribution has some local module - configuration file like /etc/modprobe.conf.local, - using that should be preferred. - -2.5. Call-ID (CID) mode - ------------------ - Call-IDs are numbers used to tag commands to, and responses from, the - Gigaset base in order to support the simultaneous handling of multiple - ISDN calls. Their use can be enabled ("CID mode") or disabled ("Unimodem - mode"). Without Call-IDs (in Unimodem mode), only a very limited set of - functions is available. It allows outgoing data connections only, but - does not signal incoming calls or other base events. - - DECT cordless data devices (M10x) permanently occupy the cordless - connection to the base while Call-IDs are activated. As the Gigaset - bases only support one DECT data connection at a time, this prevents - other DECT cordless data devices from accessing the base. - - During active operation, the driver switches to the necessary mode - automatically. However, for the reasons above, the mode chosen when - the device is not in use (idle) can be selected by the user. - - If you want to receive incoming calls, you can use the default - settings (CID mode). - - If you have several DECT data devices (M10x) which you want to use - in turn, select Unimodem mode by passing the parameter "cidmode=0" to - the driver ("modprobe usb_gigaset cidmode=0" or modprobe.conf). - - If you want both of these at once, you are out of luck. - - You can also use /sys/class/tty/ttyGxy/cidmode for changing the CID mode - setting (ttyGxy is ttyGU0 or ttyGB0). - - -3. Troubleshooting - --------------- -3.1. Solutions to frequently reported problems - ----------------------------------------- - Problem: - You have a slow provider and isdn4linux gives up dialing too early. - Solution: - Load the isdn module using the dialtimeout option. You can do this e.g. - by adding a line like - - options isdn dialtimeout=15 - - to /etc/modprobe.conf. If your distribution has some local module - configuration file like /etc/modprobe.conf.local, - using that should be preferred. - - Problem: - Your isdn script aborts with a message about isdnlog. - Solution: - Try deactivating (or commenting out) isdnlog. This driver does not - support it. - - Problem: - You have two or more DECT data adapters (M101/M105) and only the - first one you turn on works. - Solution: - Select Unimodem mode for all DECT data adapters. (see section 2.4.) - -3.2. Telling the driver to provide more information - ---------------------------------------------- - Building the driver with the "Gigaset debugging" kernel configuration - option (CONFIG_GIGASET_DEBUG) gives it the ability to produce additional - information useful for debugging. - - You can control the amount of debugging information the driver produces by - writing an appropriate value to /sys/module/gigaset/parameters/debug, e.g. - echo 0 > /sys/module/gigaset/parameters/debug - switches off debugging output completely, - echo 0x10a020 > /sys/module/gigaset/parameters/debug - enables the standard set of debugging output messages. These values are - bit patterns where every bit controls a certain type of debugging output. - See the constants DEBUG_* in the source file gigaset.h for details. - - The initial value can be set using the debug parameter when loading the - module "gigaset", e.g. by adding a line - options gigaset debug=0 - to /etc/modprobe.conf, ... - - Generated debugging information can be found - - as output of the command - dmesg - - in system log files written by your syslog daemon, usually - in /var/log/, e.g. /var/log/messages. - -3.3. Reporting problems and bugs - --------------------------- - If you can't solve problems with the driver on your own, feel free to - use one of the forums, bug trackers, or mailing lists on - http://sourceforge.net/projects/gigaset307x - or write an electronic mail to the maintainers. - - Try to provide as much information as possible, such as - - distribution - - kernel version (uname -r) - - gcc version (gcc --version) - - hardware architecture (uname -m, ...) - - type and firmware version of your device (base and wireless module, - if any) - - output of "lsusb -v" (if using an USB device) - - error messages - - relevant system log messages (it would help if you activate debug - output as described in 3.2.) - - For help with general configuration problems not specific to our driver, - such as isdn4linux and network configuration issues, please refer to the - appropriate forums and newsgroups. - -3.4. Reporting problem solutions - --------------------------- - If you solved a problem with our drivers, wrote startup scripts for your - distribution, ... feel free to contact us (using one of the places - mentioned in 3.3.). We'd like to add scripts, hints, documentation - to the driver and/or the project web page. - - -4.

(The validator -finds such dependencies in arbitrary complexity, i.e. there can be any -other locking sequence between the acquire-lock operations, the -validator will still track all dependencies between locks.) - -Furthermore, the following usage based lock dependencies are not allowed -between any two lock-classes: - - -> - -> - -The first rule comes from the fact the a hardirq-safe lock could be -taken by a hardirq context, interrupting a hardirq-unsafe lock - and -thus could result in a lock inversion deadlock. Likewise, a softirq-safe -lock could be taken by an softirq context, interrupting a softirq-unsafe -lock. - -The above rules are enforced for any locking sequence that occurs in the -kernel: when acquiring a new lock, the validator checks whether there is -any rule violation between the new lock and any of the held locks. - -When a lock-class changes its state, the following aspects of the above -dependency rules are enforced: - -- if a new hardirq-safe lock is discovered, we check whether it - took any hardirq-unsafe lock in the past. - -- if a new softirq-safe lock is discovered, we check whether it took - any softirq-unsafe lock in the past. - -- if a new hardirq-unsafe lock is discovered, we check whether any - hardirq-safe lock took it in the past. - -- if a new softirq-unsafe lock is discovered, we check whether any - softirq-safe lock took it in the past. - -(Again, we do these checks too on the basis that an interrupt context -could interrupt _any_ of the irq-unsafe or hardirq-unsafe locks, which -could lead to a lock inversion deadlock - even if that lock scenario did -not trigger in practice yet.) - -Exception: Nested data dependencies leading to nested locking -------------------------------------------------------------- - -There are a few cases where the Linux kernel acquires more than one -instance of the same lock-class. Such cases typically happen when there -is some sort of hierarchy within objects of the same type. In these -cases there is an inherent "natural" ordering between the two objects -(defined by the properties of the hierarchy), and the kernel grabs the -locks in this fixed order on each of the objects. - -An example of such an object hieararchy that results in "nested locking" -is that of a "whole disk" block-dev object and a "partition" block-dev -object; the partition is "part of" the whole device and as long as one -always takes the whole disk lock as a higher lock than the partition -lock, the lock ordering is fully correct. The validator does not -automatically detect this natural ordering, as the locking rule behind -the ordering is not static. - -In order to teach the validator about this correct usage model, new -versions of the various locking primitives were added that allow you to -specify a "nesting level". An example call, for the block device mutex, -looks like this: - -enum bdev_bd_mutex_lock_class -{ - BD_MUTEX_NORMAL, - BD_MUTEX_WHOLE, - BD_MUTEX_PARTITION -}; - - mutex_lock_nested(&bdev->bd_contains->bd_mutex, BD_MUTEX_PARTITION); - -In this case the locking is done on a bdev object that is known to be a -partition. - -The validator treats a lock that is taken in such a nested fasion as a -separate (sub)class for the purposes of validation. - -Note: When changing code to use the _nested() primitives, be careful and -check really thoroughly that the hiearchy is correctly mapped; otherwise -you can get false positives or false negatives. - -Proof of 100% correctness: --------------------------- - -The validator achieves perfect, mathematical 'closure' (proof of locking -correctness) in the sense that for every simple, standalone single-task -locking sequence that occured at least once during the lifetime of the -kernel, the validator proves it with a 100% certainty that no -combination and timing of these locking sequences can cause any class of -lock related deadlock. [*] - -I.e. complex multi-CPU and multi-task locking scenarios do not have to -occur in practice to prove a deadlock: only the simple 'component' -locking chains have to occur at least once (anytime, in any -task/context) for the validator to be able to prove correctness. (For -example, complex deadlocks that would normally need more than 3 CPUs and -a very unlikely constellation of tasks, irq-contexts and timings to -occur, can be detected on a plain, lightly loaded single-CPU system as -well!) - -This radically decreases the complexity of locking related QA of the -kernel: what has to be done during QA is to trigger as many "simple" -single-task locking dependencies in the kernel as possible, at least -once, to prove locking correctness - instead of having to trigger every -possible combination of locking interaction between CPUs, combined with -every possible hardirq and softirq nesting scenario (which is impossible -to do in practice). - -[*] assuming that the validator itself is 100% correct, and no other - part of the system corrupts the state of the validator in any way. - We also assume that all NMI/SMM paths [which could interrupt - even hardirq-disabled codepaths] are correct and do not interfere - with the validator. We also assume that the 64-bit 'chain hash' - value is unique for every lock-chain in the system. Also, lock - recursion must not be higher than 20. - -Performance: ------------- - -The above rules require _massive_ amounts of runtime checking. If we did -that for every lock taken and for every irqs-enable event, it would -render the system practically unusably slow. The complexity of checking -is O(N^2), so even with just a few hundred lock-classes we'd have to do -tens of thousands of checks for every event. - -This problem is solved by checking any given 'locking scenario' (unique -sequence of locks taken after each other) only once. A simple stack of -held locks is maintained, and a lightweight 64-bit hash value is -calculated, which hash is unique for every lock chain. The hash value, -when the chain is validated for the first time, is then put into a hash -table, which hash-table can be checked in a lockfree manner. If the -locking chain occurs again later on, the hash table tells us that we -dont have to validate the chain again. diff --git a/Documentation/memory-barriers.txt b/Documentation/memory-barriers.txt deleted file mode 100644 index 46b9b389d..000000000 --- a/Documentation/memory-barriers.txt +++ /dev/null @@ -1,2136 +0,0 @@ - ============================ - LINUX KERNEL MEMORY BARRIERS - ============================ - -By: David Howells - -Contents: - - (*) Abstract memory access model. - - - Device operations. - - Guarantees. - - (*) What are memory barriers? - - - Varieties of memory barrier. - - What may not be assumed about memory barriers? - - Data dependency barriers. - - Control dependencies. - - SMP barrier pairing. - - Examples of memory barrier sequences. - - Read memory barriers vs load speculation. - - (*) Explicit kernel barriers. - - - Compiler barrier. - - The CPU memory barriers. - - MMIO write barrier. - - (*) Implicit kernel memory barriers. - - - Locking functions. - - Interrupt disabling functions. - - Miscellaneous functions. - - (*) Inter-CPU locking barrier effects. - - - Locks vs memory accesses. - - Locks vs I/O accesses. - - (*) Where are memory barriers needed? - - - Interprocessor interaction. - - Atomic operations. - - Accessing devices. - - Interrupts. - - (*) Kernel I/O barrier effects. - - (*) Assumed minimum execution ordering model. - - (*) The effects of the cpu cache. - - - Cache coherency. - - Cache coherency vs DMA. - - Cache coherency vs MMIO. - - (*) The things CPUs get up to. - - - And then there's the Alpha. - - (*) References. - - -============================ -ABSTRACT MEMORY ACCESS MODEL -============================ - -Consider the following abstract model of the system: - - : : - : : - : : - +-------+ : +--------+ : +-------+ - | | : | | : | | - | | : | | : | | - | CPU 1 |<----->| Memory |<----->| CPU 2 | - | | : | | : | | - | | : | | : | | - +-------+ : +--------+ : +-------+ - ^ : ^ : ^ - | : | : | - | : | : | - | : v : | - | : +--------+ : | - | : | | : | - | : | | : | - +---------->| Device |<----------+ - : | | : - : | | : - : +--------+ : - : : - -Each CPU executes a program that generates memory access operations.

They impose a perceived partial -ordering over the memory operations on either side of the barrier. - -Such enforcement is important because the CPUs and other devices in a system -can use a variety of tricks to improve performance - including reordering, -deferral and combination of memory operations; speculative loads; speculative -branch prediction and various types of caching. Memory barriers are used to -override or suppress these tricks, allowing the code to sanely control the -interaction of multiple CPUs and/or devices. - - -VARIETIES OF MEMORY BARRIER ---------------------------- - -Memory barriers come in four basic varieties: - - (1) Write (or store) memory barriers. - - A write memory barrier gives a guarantee that all the STORE operations - specified before the barrier will appear to happen before all the STORE - operations specified after the barrier with respect to the other - components of the system. - - A write barrier is a partial ordering on stores only; it is not required - to have any effect on loads. - - A CPU can be viewed as committing a sequence of store operations to the - memory system as time progresses. All stores before a write barrier will - occur in the sequence _before_ all the stores after the write barrier. - - [!] Note that write barriers should normally be paired with read or data - dependency barriers; see the "SMP barrier pairing" subsection. - - - (2) Data dependency barriers. - - A data dependency barrier is a weaker form of read barrier. In the case - where two loads are performed such that the second depends on the result - of the first (eg: the first load retrieves the address to which the second - load will be directed), a data dependency barrier would be required to - make sure that the target of the second load is updated before the address - obtained by the first load is accessed. - - A data dependency barrier is a partial ordering on interdependent loads - only; it is not required to have any effect on stores, independent loads - or overlapping loads. - - As mentioned in (1), the other CPUs in the system can be viewed as - committing sequences of stores to the memory system that the CPU being - considered can then perceive. A data dependency barrier issued by the CPU - under consideration guarantees that for any load preceding it, if that - load touches one of a sequence of stores from another CPU, then by the - time the barrier completes, the effects of all the stores prior to that - touched by the load will be perceptible to any loads issued after the data - dependency barrier. - - See the "Examples of memory barrier sequences" subsection for diagrams - showing the ordering constraints. - - [!] Note that the first load really has to have a _data_ dependency and - not a control dependency. If the address for the second load is dependent - on the first load, but the dependency is through a conditional rather than - actually loading the address itself, then it's a _control_ dependency and - a full read barrier or better is required. See the "Control dependencies" - subsection for more information. - - [!] Note that data dependency barriers should normally be paired with - write barriers; see the "SMP barrier pairing" subsection. - - - (3) Read (or load) memory barriers. - - A read barrier is a data dependency barrier plus a guarantee that all the - LOAD operations specified before the barrier will appear to happen before - all the LOAD operations specified after the barrier with respect to the - other components of the system. - - A read barrier is a partial ordering on loads only; it is not required to - have any effect on stores. - - Read memory barriers imply data dependency barriers, and so can substitute - for them. - - [!] Note that read barriers should normally be paired with write barriers; - see the "SMP barrier pairing" subsection. - - - (4) General memory barriers. - - A general memory barrier gives a guarantee that all the LOAD and STORE - operations specified before the barrier will appear to happen before all - the LOAD and STORE operations specified after the barrier with respect to - the other components of the system. - - A general memory barrier is a partial ordering over both loads and stores. - - General memory barriers imply both read and write memory barriers, and so - can substitute for either. - - -And a couple of implicit varieties: - - (5) LOCK operations. - - This acts as a one-way permeable barrier. It guarantees that all memory - operations after the LOCK operation will appear to happen after the LOCK - operation with respect to the other components of the system. - - Memory operations that occur before a LOCK operation may appear to happen - after it completes. - - A LOCK operation should almost always be paired with an UNLOCK operation. - - - (6) UNLOCK operations. - - This also acts as a one-way permeable barrier. It guarantees that all - memory operations before the UNLOCK operation will appear to happen before - the UNLOCK operation with respect to the other components of the system. - - Memory operations that occur after an UNLOCK operation may appear to - happen before it completes. - - LOCK and UNLOCK operations are guaranteed to appear with respect to each - other strictly in the order specified. - - The use of LOCK and UNLOCK operations generally precludes the need for - other sorts of memory barrier (but note the exceptions mentioned in the - subsection "MMIO write barrier"). - - -Memory barriers are only required where there's a possibility of interaction -between two CPUs or between a CPU and a device. If it can be guaranteed that -there won't be any such interaction in any particular piece of code, then -memory barriers are unnecessary in that piece of code. - - -Note that these are the _minimum_ guarantees. Different architectures may give -more substantial guarantees, but they may _not_ be relied upon outside of arch -specific code. - - -WHAT MAY NOT BE ASSUMED ABOUT MEMORY BARRIERS? ----------------------------------------------- - -There are certain things that the Linux kernel memory barriers do not guarantee: - - (*) There is no guarantee that any of the memory accesses specified before a - memory barrier will be _complete_ by the completion of a memory barrier - instruction; the barrier can be considered to draw a line in that CPU's - access queue that accesses of the appropriate type may not cross. - - (*) There is no guarantee that issuing a memory barrier on one CPU will have - any direct effect on another CPU or any other hardware in the system. The - indirect effect will be the order in which the second CPU sees the effects - of the first CPU's accesses occur, but see the next point: - - (*) There is no guarantee that a CPU will see the correct order of effects - from a second CPU's accesses, even _if_ the second CPU uses a memory - barrier, unless the first CPU _also_ uses a matching memory barrier (see - the subsection on "SMP Barrier Pairing"). - - (*) There is no guarantee that some intervening piece of off-the-CPU - hardware[*] will not reorder the memory accesses. CPU cache coherency - mechanisms should propagate the indirect effects of a memory barrier - between CPUs, but might not do so in order. - - [*] For information on bus mastering DMA and coherency please read: - - Documentation/pci.txt - Documentation/DMA-mapping.txt - Documentation/DMA-API.txt - - -DATA DEPENDENCY BARRIERS ------------------------- - -The usage requirements of data dependency barriers are a little subtle, and -it's not always obvious that they're needed. To illustrate, consider the -following sequence of events: - - CPU 1 CPU 2 - =============== =============== - { A == 1, B == 2, C = 3, P == &A, Q == &C } - B = 4; - - P = &B - Q = P; - D = *Q; - -There's a clear data dependency here, and it would seem that by the end of the -sequence, Q must be either &A or &B, and that: - - (Q == &A) implies (D == 1) - (Q == &B) implies (D == 4) - -But! CPU 2's perception of P may be updated _before_ its perception of B, thus -leading to the following situation: - - (Q == &B) and (D == 2) ???? - -Whilst this may seem like a failure of coherency or causality maintenance, it -isn't, and this behaviour can be observed on certain real CPUs (such as the DEC -Alpha). - -To deal with this, a data dependency barrier or better must be inserted -between the address load and the data load: - - CPU 1 CPU 2 - =============== =============== - { A == 1, B == 2, C = 3, P == &A, Q == &C } - B = 4; - - P = &B - Q = P; - - D = *Q; - -This enforces the occurrence of one of the two implications, and prevents the -third possibility from arising. - -[!] Note that this extremely counterintuitive situation arises most easily on -machines with split caches, so that, for example, one cache bank processes -even-numbered cache lines and the other bank processes odd-numbered cache -lines. The pointer P might be stored in an odd-numbered cache line, and the -variable B might be stored in an even-numbered cache line. Then, if the -even-numbered bank of the reading CPU's cache is extremely busy while the -odd-numbered bank is idle, one can see the new value of the pointer P (&B), -but the old value of the variable B (2). - - -Another example of where data dependency barriers might by required is where a -number is read from memory and then used to calculate the index for an array -access: - - CPU 1 CPU 2 - =============== =============== - { M[0] == 1, M[1] == 2, M[3] = 3, P == 0, Q == 3 } - M[1] = 4; - - P = 1 - Q = P; - - D = M[Q]; - - -The data dependency barrier is very important to the RCU system, for example. -See rcu_dereference() in include/linux/rcupdate.h. This permits the current -target of an RCU'd pointer to be replaced with a new modified target, without -the replacement target appearing to be incompletely initialised. - -See also the subsection on "Cache Coherency" for a more thorough example. - - -CONTROL DEPENDENCIES --------------------- - -A control dependency requires a full read memory barrier, not simply a data -dependency barrier to make it work correctly. Consider the following bit of -code: - - q = &a; - if (p) - q = &b; - - x = *q; - -This will not have the desired effect because there is no actual data -dependency, but rather a control dependency that the CPU may short-circuit by -attempting to predict the outcome in advance. In such a case what's actually -required is: - - q = &a; - if (p) - q = &b; - - x = *q; - - -SMP BARRIER PAIRING -------------------- - -When dealing with CPU-CPU interactions, certain types of memory barrier should -always be paired. A lack of appropriate pairing is almost certainly an error. - -A write barrier should always be paired with a data dependency barrier or read -barrier, though a general barrier would also be viable. Similarly a read -barrier or a data dependency barrier should always be paired with at least an -write barrier, though, again, a general barrier is viable: - - CPU 1 CPU 2 - =============== =============== - a = 1; - - b = 2; x = b; - - y = a; - -Or: - - CPU 1 CPU 2 - =============== =============================== - a = 1; - - b = &a; x = b; - - y = *x; - -Basically, the read barrier always has to be there, even though it can be of -the "weaker" type. - -[!] Note that the stores before the write barrier would normally be expected to -match the loads after the read barrier or data dependency barrier, and vice -versa: - - CPU 1 CPU 2 - =============== =============== - a = 1; }---- --->{ v = c - b = 2; } \ / { w = d - \ - c = 3; } / \ { x = a; - d = 4; }---- --->{ y = b; - - -EXAMPLES OF MEMORY BARRIER SEQUENCES ------------------------------------- - -Firstly, write barriers act as a partial orderings on store operations. -Consider the following sequence of events: - - CPU 1 - ======================= - STORE A = 1 - STORE B = 2 - STORE C = 3 - - STORE D = 4 - STORE E = 5 - -This sequence of events is committed to the memory coherence system in an order -that the rest of the system might perceive as the unordered set of { STORE A, -STORE B, STORE C } all occurring before the unordered set of { STORE D, STORE E -}: - - +-------+ : : - | | +------+ - | |------>| C=3 | } /\ - | | : +------+ }----- \ -----> Events perceptible - | | : | A=1 | } \/ to rest of system - | | : +------+ } - | CPU 1 | : | B=2 | } - | | +------+ } - | | wwwwwwwwwwwwwwww } <--- At this point the write barrier - | | +------+ } requires all stores prior to the - | | : | E=5 | } barrier to be committed before - | | : +------+ } further stores may be take place. - | |------>| D=4 | } - | | +------+ - +-------+ : : - | - | Sequence in which stores are committed to the - | memory system by CPU 1 - V - - -Secondly, data dependency barriers act as a partial orderings on data-dependent -loads.

There are, however, three -circumstances in which reordering definitely _could_ be a problem: - - (*) Interprocessor interaction. - - (*) Atomic operations. - - (*) Accessing devices (I/O). - - (*) Interrupts. - - -INTERPROCESSOR INTERACTION --------------------------- - -When there's a system with more than one processor, more than one CPU in the -system may be working on the same data set at the same time. This can cause -synchronisation problems, and the usual way of dealing with them is to use -locks. Locks, however, are quite expensive, and so it may be preferable to -operate without the use of a lock if at all possible. In such a case -operations that affect both CPUs may have to be carefully ordered to prevent -a malfunction. - -Consider, for example, the R/W semaphore slow path. Here a waiting process is -queued on the semaphore, by virtue of it having a piece of its stack linked to -the semaphore's list of waiting processes: - - struct rw_semaphore { - ... - spinlock_t lock; - struct list_head waiters; - }; - - struct rwsem_waiter { - struct list_head list; - struct task_struct *task; - }; - -To wake up a particular waiter, the up_read() or up_write() functions have to: - - (1) read the next pointer from this waiter's record to know as to where the - next waiter record is; - - (4) read the pointer to the waiter's task structure; - - (3) clear the task pointer to tell the waiter it has been given the semaphore; - - (4) call wake_up_process() on the task; and - - (5) release the reference held on the waiter's task struct. - -In otherwords, it has to perform this sequence of events: - - LOAD waiter->list.next; - LOAD waiter->task; - STORE waiter->task; - CALL wakeup - RELEASE task - -and if any of these steps occur out of order, then the whole thing may -malfunction. - -Once it has queued itself and dropped the semaphore lock, the waiter does not -get the lock again; it instead just waits for its task pointer to be cleared -before proceeding. Since the record is on the waiter's stack, this means that -if the task pointer is cleared _before_ the next pointer in the list is read, -another CPU might start processing the waiter and might clobber the waiter's -stack before the up*() function has a chance to read the next pointer. - -Consider then what might happen to the above sequence of events: - - CPU 1 CPU 2 - =============================== =============================== - down_xxx() - Queue waiter - Sleep - up_yyy() - LOAD waiter->task; - STORE waiter->task; - Woken up by other event - - Resume processing - down_xxx() returns - call foo() - foo() clobbers *waiter - - LOAD waiter->list.next; - --- OOPS --- - -This could be dealt with using the semaphore lock, but then the down_xxx() -function has to needlessly get the spinlock again after being woken up. - -The way to deal with this is to insert a general SMP memory barrier: - - LOAD waiter->list.next; - LOAD waiter->task; - smp_mb(); - STORE waiter->task; - CALL wakeup - RELEASE task - -In this case, the barrier makes a guarantee that all memory accesses before the -barrier will appear to happen before all the memory accesses after the barrier -with respect to the other CPUs on the system. It does _not_ guarantee that all -the memory accesses before the barrier will be complete by the time the barrier -instruction itself is complete. - -On a UP system - where this wouldn't be a problem - the smp_mb() is just a -compiler barrier, thus making sure the compiler emits the instructions in the -right order without actually intervening in the CPU. Since there's only one -CPU, that CPU's dependency ordering logic will take care of everything else. - - -ATOMIC OPERATIONS ------------------ - -Whilst they are technically interprocessor interaction considerations, atomic -operations are noted specially as some of them imply full memory barriers and -some don't, but they're very heavily relied on as a group throughout the -kernel. - -Any atomic operation that modifies some state in memory and returns information -about the state (old or new) implies an SMP-conditional general memory barrier -(smp_mb()) on each side of the actual operation. These include: - - xchg(); - cmpxchg(); - atomic_cmpxchg(); - atomic_inc_return(); - atomic_dec_return(); - atomic_add_return(); - atomic_sub_return(); - atomic_inc_and_test(); - atomic_dec_and_test(); - atomic_sub_and_test(); - atomic_add_negative(); - atomic_add_unless(); - test_and_set_bit(); - test_and_clear_bit(); - test_and_change_bit(); - -These are used for such things as implementing LOCK-class and UNLOCK-class -operations and adjusting reference counters towards object destruction, and as -such the implicit memory barrier effects are necessary. - - -The following operation are potential problems as they do _not_ imply memory -barriers, but might be used for implementing such things as UNLOCK-class -operations: - - atomic_set(); - set_bit(); - clear_bit(); - change_bit(); - -With these the appropriate explicit memory barrier should be used if necessary -(smp_mb__before_clear_bit() for instance). - - -The following also do _not_ imply memory barriers, and so may require explicit -memory barriers under some circumstances (smp_mb__before_atomic_dec() for -instance)): - - atomic_add(); - atomic_sub(); - atomic_inc(); - atomic_dec(); - -If they're used for statistics generation, then they probably don't need memory -barriers, unless there's a coupling between statistical data. - -If they're used for reference counting on an object to control its lifetime, -they probably don't need memory barriers because either the reference count -will be adjusted inside a locked section, or the caller will already hold -sufficient references to make the lock, and thus a memory barrier unnecessary. - -If they're used for constructing a lock of some description, then they probably -do need memory barriers as a lock primitive generally has to do things in a -specific order. - - -Basically, each usage case has to be carefully considered as to whether memory -barriers are needed or not. - -[!] Note that special memory barrier primitives are available for these -situations because on some CPUs the atomic instructions used imply full memory -barriers, and so barrier instructions are superfluous in conjunction with them, -and in such cases the special barrier primitives will be no-ops. - -See Documentation/atomic_ops.txt for more information. - - -ACCESSING DEVICES ------------------ - -Many devices can be memory mapped, and so appear to the CPU as if they're just -a set of memory locations. To control such a device, the driver usually has to -make the right memory accesses in exactly the right order. - -However, having a clever CPU or a clever compiler creates a potential problem -in that the carefully sequenced accesses in the driver code won't reach the -device in the requisite order if the CPU or the compiler thinks it is more -efficient to reorder, combine or merge accesses - something that would cause -the device to malfunction. - -Inside of the Linux kernel, I/O should be done through the appropriate accessor -routines - such as inb() or writel() - which know how to make such accesses -appropriately sequential. Whilst this, for the most part, renders the explicit -use of memory barriers unnecessary, there are a couple of situations where they -might be needed: - - (1) On some systems, I/O stores are not strongly ordered across all CPUs, and - so for _all_ general drivers locks should be used and mmiowb() must be - issued prior to unlocking the critical section. - - (2) If the accessor functions are used to refer to an I/O memory window with - relaxed memory access properties, then _mandatory_ memory barriers are - required to enforce ordering. - -See Documentation/DocBook/deviceiobook.tmpl for more information. - - -INTERRUPTS ----------- - -A driver may be interrupted by its own interrupt service routine, and thus the -two parts of the driver may interfere with each other's attempts to control or -access the device. - -This may be alleviated - at least in part - by disabling local interrupts (a -form of locking), such that the critical operations are all contained within -the interrupt-disabled section in the driver. Whilst the driver's interrupt -routine is executing, the driver's core may not run on the same CPU, and its -interrupt is not permitted to happen again until the current interrupt has been -handled, thus the interrupt handler does not need to lock against that. - -However, consider a driver that was talking to an ethernet card that sports an -address register and a data register. If that driver's core talks to the card -under interrupt-disablement and then the driver's interrupt handler is invoked: - - LOCAL IRQ DISABLE - writew(ADDR, 3); - writew(DATA, y); - LOCAL IRQ ENABLE - - writew(ADDR, 4); - q = readw(DATA); - - -The store to the data register might happen after the second store to the -address register if ordering rules are sufficiently relaxed: - - STORE *ADDR = 3, STORE *ADDR = 4, STORE *DATA = y, q = LOAD *DATA - - -If ordering rules are relaxed, it must be assumed that accesses done inside an -interrupt disabled section may leak outside of it and may interleave with -accesses performed in an interrupt - and vice versa - unless implicit or -explicit barriers are used. - -Normally this won't be a problem because the I/O accesses done inside such -sections will include synchronous load operations on strictly ordered I/O -registers that form implicit I/O barriers. If this isn't sufficient then an -mmiowb() may need to be used explicitly. - - -A similar situation may occur between an interrupt routine and two routines -running on separate CPUs that communicate with each other. If such a case is -likely, then interrupt-disabling locks should be used to guarantee ordering. - - -========================== -KERNEL I/O BARRIER EFFECTS -========================== - -When accessing I/O memory, drivers should use the appropriate accessor -functions: - - (*) inX(), outX(): - - These are intended to talk to I/O space rather than memory space, but - that's primarily a CPU-specific concept. The i386 and x86_64 processors do - indeed have special I/O space access cycles and instructions, but many - CPUs don't have such a concept. - - The PCI bus, amongst others, defines an I/O space concept - which on such - CPUs as i386 and x86_64 cpus readily maps to the CPU's concept of I/O - space. However, it may also be mapped as a virtual I/O space in the CPU's - memory map, particularly on those CPUs that don't support alternate I/O - spaces. - - Accesses to this space may be fully synchronous (as on i386), but - intermediary bridges (such as the PCI host bridge) may not fully honour - that. - - They are guaranteed to be fully ordered with respect to each other. - - They are not guaranteed to be fully ordered with respect to other types of - memory and I/O operation. - - (*) readX(), writeX(): - - Whether these are guaranteed to be fully ordered and uncombined with - respect to each other on the issuing CPU depends on the characteristics - defined for the memory window through which they're accessing. On later - i386 architecture machines, for example, this is controlled by way of the - MTRR registers. - - Ordinarily, these will be guaranteed to be fully ordered and uncombined,, - provided they're not accessing a prefetchable device. - - However, intermediary hardware (such as a PCI bridge) may indulge in - deferral if it so wishes; to flush a store, a load from the same location - is preferred[*], but a load from the same device or from configuration - space should suffice for PCI. - - [*] NOTE! attempting to load from the same location as was written to may - cause a malfunction - consider the 16550 Rx/Tx serial registers for - example. - - Used with prefetchable I/O memory, an mmiowb() barrier may be required to - force stores to be ordered. - - Please refer to the PCI specification for more information on interactions - between PCI transactions. - - (*) readX_relaxed() - - These are similar to readX(), but are not guaranteed to be ordered in any - way. Be aware that there is no I/O read barrier available. - - (*) ioreadX(), iowriteX() - - These will perform as appropriate for the type of access they're actually - doing, be it inX()/outX() or readX()/writeX(). - - -======================================== -ASSUMED MINIMUM EXECUTION ORDERING MODEL -======================================== - -It has to be assumed that the conceptual CPU is weakly-ordered but that it will -maintain the appearance of program causality with respect to itself. Some CPUs -(such as i386 or x86_64) are more constrained than others (such as powerpc or -frv), and so the most relaxed case (namely DEC Alpha) must be assumed outside -of arch-specific code. - -This means that it must be considered that the CPU will execute its instruction -stream in any order it feels like - or even in parallel - provided that if an -instruction in the stream depends on the an earlier instruction, then that -earlier instruction must be sufficiently complete[*] before the later -instruction may proceed; in other words: provided that the appearance of -causality is maintained. - - [*] Some instructions have more than one effect - such as changing the - condition codes, changing registers or changing memory - and different - instructions may depend on different effects. - -A CPU may also discard any instruction sequence that winds up having no -ultimate effect. For example, if two adjacent instructions both load an -immediate value into the same register, the first may be discarded. - - -Similarly, it has to be assumed that compiler might reorder the instruction -stream in any way it sees fit, again provided the appearance of causality is -maintained. - - -============================ -THE EFFECTS OF THE CPU CACHE -============================ - -The way cached memory operations are perceived across the system is affected to -a certain extent by the caches that lie between CPUs and memory, and by the -memory coherence system that maintains the consistency of state in the system. - -As far as the way a CPU interacts with another part of the system through the -caches goes, the memory system has to include the CPU's caches, and memory -barriers for the most part act at the interface between the CPU and its cache -(memory barriers logically act on the dotted line in the following diagram): - - <--- CPU ---> : <----------- Memory -----------> - : - +--------+ +--------+ : +--------+ +-----------+ - | | | | : | | | | +--------+ - | CPU | | Memory | : | CPU | | | | | - | Core |--->| Access |----->| Cache |<-->| | | | - | | | Queue | : | | | |--->| Memory | - | | | | : | | | | | | - +--------+ +--------+ : +--------+ | | | | - : | Cache | +--------+ - : | Coherency | - : | Mechanism | +--------+ - +--------+ +--------+ : +--------+ | | | | - | | | | : | | | | | | - | CPU | | Memory | : | CPU | | |--->| Device | - | Core |--->| Access |----->| Cache |<-->| | | | - | | | Queue | : | | | | | | - | | | | : | | | | +--------+ - +--------+ +--------+ : +--------+ +-----------+ - : - : - -Although any particular load or store may not actually appear outside of the -CPU that issued it since it may have been satisfied within the CPU's own cache, -it will still appear as if the full memory access had taken place as far as the -other CPUs are concerned since the cache coherency mechanisms will migrate the -cacheline over to the accessing CPU and propagate the effects upon conflict. - -The CPU core may execute instructions in any order it deems fit, provided the -expected program causality appears to be maintained. Some of the instructions -generate load and store operations which then go into the queue of memory -accesses to be performed. The core may place these in the queue in any order -it wishes, and continue execution until it is forced to wait for an instruction -to complete. - -What memory barriers are concerned with is controlling the order in which -accesses cross from the CPU side of things to the memory side of things, and -the order in which the effects are perceived to happen by the other observers -in the system. - -[!] Memory barriers are _not_ needed within a given CPU, as CPUs always see -their own loads and stores as if they had happened in program order. - -[!] MMIO or other device accesses may bypass the cache system. This depends on -the properties of the memory window through which devices are accessed and/or -the use of any special device communication instructions the CPU may have. - - -CACHE COHERENCY ---------------- - -Life isn't quite as simple as it may appear above, however: for while the -caches are expected to be coherent, there's no guarantee that that coherency -will be ordered. This means that whilst changes made on one CPU will -eventually become visible on all CPUs, there's no guarantee that they will -become apparent in the same order on those other CPUs. - - -Consider dealing with a system that has pair of CPUs (1 & 2), each of which has -a pair of parallel data caches (CPU 1 has A/B, and CPU 2 has C/D): - - : - : +--------+ - : +---------+ | | - +--------+ : +--->| Cache A |<------->| | - | | : | +---------+ | | - | CPU 1 |<---+ | | - | | : | +---------+ | | - +--------+ : +--->| Cache B |<------->| | - : +---------+ | | - : | Memory | - : +---------+ | System | - +--------+ : +--->| Cache C |<------->| | - | | : | +---------+ | | - | CPU 2 |<---+ | | - | | : | +---------+ | | - +--------+ : +--->| Cache D |<------->| | - : +---------+ | | - : +--------+ - : - -Imagine the system has the following properties: - - (*) an odd-numbered cache line may be in cache A, cache C or it may still be - resident in memory; - - (*) an even-numbered cache line may be in cache B, cache D or it may still be - resident in memory; - - (*) whilst the CPU core is interrogating one cache, the other cache may be - making use of the bus to access the rest of the system - perhaps to - displace a dirty cacheline or to do a speculative load; - - (*) each cache has a queue of operations that need to be applied to that cache - to maintain coherency with the rest of the system; - - (*) the coherency queue is not flushed by normal loads to lines already - present in the cache, even though the contents of the queue may - potentially effect those loads. - -Imagine, then, that two writes are made on the first CPU, with a write barrier -between them to guarantee that they will appear to reach that CPU's caches in -the requisite order: - - CPU 1 CPU 2 COMMENT - =============== =============== ======================================= - u == 0, v == 1 and p == &u, q == &u - v = 2; - smp_wmb(); Make sure change to v visible before - change to p - v is now in cache A exclusively - p = &v; - p is now in cache B exclusively - -The write memory barrier forces the other CPUs in the system to perceive that -the local CPU's caches have apparently been updated in the correct order. But -now imagine that the second CPU that wants to read those values: - - CPU 1 CPU 2 COMMENT - =============== =============== ======================================= - ... - q = p; - x = *q; - -The above pair of reads may then fail to happen in expected order, as the -cacheline holding p may get updated in one of the second CPU's caches whilst -the update to the cacheline holding v is delayed in the other of the second -CPU's caches by some other cache event: - - CPU 1 CPU 2 COMMENT - =============== =============== ======================================= - u == 0, v == 1 and p == &u, q == &u - v = 2; - smp_wmb(); - - - p = &v; q = p; - - - - x = *q; - Reads from v before v updated in cache - - - -Basically, whilst both cachelines will be updated on CPU 2 eventually, there's -no guarantee that, without intervention, the order of update will be the same -as that committed on CPU 1. - - -To intervene, we need to interpolate a data dependency barrier or a read -barrier between the loads. This will force the cache to commit its coherency -queue before processing any further requests: - - CPU 1 CPU 2 COMMENT - =============== =============== ======================================= - u == 0, v == 1 and p == &u, q == &u - v = 2; - smp_wmb(); - - - p = &b; q = p; - - - - smp_read_barrier_depends() - - - x = *q; - Reads from v after v updated in cache - - -This sort of problem can be encountered on DEC Alpha processors as they have a -split cache that improves performance by making better use of the data bus. -Whilst most CPUs do imply a data dependency barrier on the read when a memory -access depends on a read, not all do, so it may not be relied on. - -Other CPUs may also have split caches, but must coordinate between the various -cachelets for normal memory accesss. The semantics of the Alpha removes the -need for coordination in absence of memory barriers. - - -CACHE COHERENCY VS DMA ----------------------- - -Not all systems maintain cache coherency with respect to devices doing DMA. In -such cases, a device attempting DMA may obtain stale data from RAM because -dirty cache lines may be resident in the caches of various CPUs, and may not -have been written back to RAM yet. To deal with this, the appropriate part of -the kernel must flush the overlapping bits of cache on each CPU (and maybe -invalidate them as well). - -In addition, the data DMA'd to RAM by a device may be overwritten by dirty -cache lines being written back to RAM from a CPU's cache after the device has -installed its own data, or cache lines simply present in a CPUs cache may -simply obscure the fact that RAM has been updated, until at such time as the -cacheline is discarded from the CPU's cache and reloaded. To deal with this, -the appropriate part of the kernel must invalidate the overlapping bits of the -cache on each CPU. - -See Documentation/cachetlb.txt for more information on cache management. - - -CACHE COHERENCY VS MMIO ------------------------ - -Memory mapped I/O usually takes place through memory locations that are part of -a window in the CPU's memory space that have different properties assigned than -the usual RAM directed window. - -Amongst these properties is usually the fact that such accesses bypass the -caching entirely and go directly to the device buses. This means MMIO accesses -may, in effect, overtake accesses to cached memory that were emitted earlier. -A memory barrier isn't sufficient in such a case, but rather the cache must be -flushed between the cached memory write and the MMIO access if the two are in -any way dependent. - - -========================= -THE THINGS CPUS GET UP TO -========================= - -A programmer might take it for granted that the CPU will perform memory -operations in exactly the order specified, so that if a CPU is, for example, -given the following piece of code to execute: - - a = *A; - *B = b; - c = *C; - d = *D; - *E = e; - -They would then expect that the CPU will complete the memory operation for each -instruction before moving on to the next one, leading to a definite sequence of -operations as seen by external observers in the system: - - LOAD *A, STORE *B, LOAD *C, LOAD *D, STORE *E. - - -Reality is, of course, much messier. With many CPUs and compilers, the above -assumption doesn't hold because: - - (*) loads are more likely to need to be completed immediately to permit - execution progress, whereas stores can often be deferred without a - problem; - - (*) loads may be done speculatively, and the result discarded should it prove - to have been unnecessary; - - (*) loads may be done speculatively, leading to the result having being - fetched at the wrong time in the expected sequence of events; - - (*) the order of the memory accesses may be rearranged to promote better use - of the CPU buses and caches; - - (*) loads and stores may be combined to improve performance when talking to - memory or I/O hardware that can do batched accesses of adjacent locations, - thus cutting down on transaction setup costs (memory and PCI devices may - both be able to do this); and - - (*) the CPU's data cache may affect the ordering, and whilst cache-coherency - mechanisms may alleviate this - once the store has actually hit the cache - - there's no guarantee that the coherency management will be propagated in - order to other CPUs. - -So what another CPU, say, might actually observe from the above piece of code -is: - - LOAD *A, ..., LOAD {*C,*D}, STORE *E, STORE *B - - (Where "LOAD {*C,*D}" is a combined load) - - -However, it is guaranteed that a CPU will be self-consistent: it will see its -_own_ accesses appear to be correctly ordered, without the need for a memory -barrier. For instance with the following code: - - U = *A; - *A = V; - *A = W; - X = *A; - *A = Y; - Z = *A; - -and assuming no intervention by an external influence, it can be assumed that -the final result will appear to be: - - U == the original value of *A - X == W - Z == Y - *A == Y - -The code above may cause the CPU to generate the full sequence of memory -accesses: - - U=LOAD *A, STORE *A=V, STORE *A=W, X=LOAD *A, STORE *A=Y, Z=LOAD *A - -in that order, but, without intervention, the sequence may have almost any -combination of elements combined or discarded, provided the program's view of -the world remains consistent. - -The compiler may also combine, discard or defer elements of the sequence before -the CPU even sees them. - -For instance: - - *A = V; - *A = W; - -may be reduced to: - - *A = W; - -since, without a write barrier, it can be assumed that the effect of the -storage of V to *A is lost. Similarly: - - *A = Y; - Z = *A; - -may, without a memory barrier, be reduced to: - - *A = Y; - Z = Y; - -and the LOAD operation never appear outside of the CPU. - - -AND THEN THERE'S THE ALPHA --------------------------- - -The DEC Alpha CPU is one of the most relaxed CPUs there is. Not only that, -some versions of the Alpha CPU have a split data cache, permitting them to have -two semantically related cache lines updating at separate times. This is where -the data dependency barrier really becomes necessary as this synchronises both -caches with the memory coherence system, thus making it seem like pointer -changes vs new data occur in the right order. - -The Alpha defines the Linux's kernel's memory barrier model. - -See the subsection on "Cache Coherency" above. - - -========== -REFERENCES -========== - -Alpha AXP Architecture Reference Manual, Second Edition (Sites & Witek, -Digital Press) - Chapter 5.2: Physical Address Space Characteristics - Chapter 5.4: Caches and Write Buffers - Chapter 5.5: Data Sharing - Chapter 5.6: Read/Write Ordering - -AMD64 Architecture Programmer's Manual Volume 2: System Programming - Chapter 7.1: Memory-Access Ordering - Chapter 7.4: Buffering and Combining Memory Writes - -IA-32 Intel Architecture Software Developer's Manual, Volume 3: -System Programming Guide - Chapter 7.1: Locked Atomic Operations - Chapter 7.2: Memory Ordering - Chapter 7.4: Serializing Instructions - -The SPARC Architecture Manual, Version 9 - Chapter 8: Memory Models - Appendix D: Formal Specification of the Memory Models - Appendix J: Programming with the Memory Models - -UltraSPARC Programmer Reference Manual - Chapter 5: Memory Accesses and Cacheability - Chapter 15: Sparc-V9 Memory Models - -UltraSPARC III Cu User's Manual - Chapter 9: Memory Models - -UltraSPARC IIIi Processor User's Manual - Chapter 8: Memory Models - -UltraSPARC Architecture 2005 - Chapter 9: Memory - Appendix D: Formal Specifications of the Memory Models - -UltraSPARC T1 Supplement to the UltraSPARC Architecture 2005 - Chapter 8: Memory Models - Appendix F: Caches and Cache Coherency - -Solaris Internals, Core Kernel Architecture, p63-68: - Chapter 3.3: Hardware Considerations for Locks and - Synchronization - -Unix Systems for Modern Architectures, Symmetric Multiprocessing and Caching -for Kernel Programmers: - Chapter 13: Other Memory Models - -Intel Itanium Architecture Software Developer's Manual: Volume 1: - Section 2.6: Speculation - Section 4.4: Memory Access diff --git a/Documentation/mkdev.cciss b/Documentation/mkdev.cciss deleted file mode 100644 index fbbaf30a7..000000000 --- a/Documentation/mkdev.cciss +++ /dev/null @@ -1,40 +0,0 @@ -#!/bin/sh -# Script to create device nodes for SMART array controllers -# Usage: -# mkdev.cciss [num controllers] [num log volumes] [num partitions] -# -# With no arguments, the script assumes 1 controller, 16 logical volumes, -# and 16 partitions/volume, which is adequate for most configurations. -# -# If you had 5 controllers and were planning on no more than 4 logical volumes -# each, using a maximum of 8 partitions per volume, you could say: -# -# mkdev.cciss 5 4 8 -# -# Of course, this has no real benefit over "mkdev.cciss 5" except that it -# doesn't create so many device nodes in /dev/cciss. - -NR_CTLR=${1-1} -NR_VOL=${2-16} -NR_PART=${3-16} - -if [ !

Although router's job may be as simple as taking your local network -traffic, converting it to WAN format and piping it through the WAN link, these -devices are notoriously expensive, with prices as much as 2 - 5 times higher -then the price of a typical PC box. - -Alternatively, considering robustness and multitasking capabilities of Linux, -an internal router can be built (most routers use some sort of stripped down -Unix-like operating system anyway). With a number of relatively inexpensive WAN -interface cards available on the market, a perfectly usable router can be -built for less than half a price of an external router. Yet a Linux box -acting as a router can still be used for other purposes, such as fire-walling, -running FTP, WWW or DNS server, etc. - -This kernel module introduces the notion of a WAN Link Driver (WLD) to Linux -operating system and provides generic hardware-independent services for such -drivers. Why can existing Linux network device interface not be used for -this purpose? Well, it can. However, there are a few key differences between -a typical network interface (e.g. Ethernet) and a WAN link. - -Many WAN protocols, such as X.25 and frame relay, allow for multiple logical -connections (known as `virtual circuits' in X.25 terminology) over a single -physical link. Each such virtual circuit may (and almost always does) lead -to a different geographical location and, therefore, different network. As a -result, it is the virtual circuit, not the physical link, that represents a -route and, therefore, a network interface in Linux terms. - -To further complicate things, virtual circuits are usually volatile in nature -(excluding so called `permanent' virtual circuits or PVCs). With almost no -time required to set up and tear down a virtual circuit, it is highly desirable -to implement on-demand connections in order to minimize network charges. So -unlike a typical network driver, the WAN driver must be able to handle multiple -network interfaces and cope as multiple virtual circuits come into existence -and go away dynamically. - -Last, but not least, WAN configuration is much more complex than that of say -Ethernet and may well amount to several dozens of parameters. Some of them -are "link-wide" while others are virtual circuit-specific. The same holds -true for WAN statistics which is by far more extensive and extremely useful -when troubleshooting WAN connections. Extending the ifconfig utility to suit -these needs may be possible, but does not seem quite reasonable. Therefore, a -WAN configuration utility and corresponding application programmer's interface -is needed for this purpose. - -Most of these problems are taken care of by this module. Its goal is to -provide a user with more-or-less standard look and feel for all WAN devices and -assist a WAN device driver writer by providing common services, such as: - - o User-level interface via /proc file system - o Centralized configuration - o Device management (setup, shutdown, etc.) - o Network interface management (dynamic creation/destruction) - o Protocol encapsulation/decapsulation - -To ba able to use the Linux WAN Router you will also need a WAN Tools package -available from - - ftp.sangoma.com/pub/linux/current_wanpipe/wanpipe-X.Y.Z.tgz - -where vX.Y.Z represent the wanpipe version number. - -For technical questions and/or comments please e-mail to ncorbic@sangoma.com. -For general inquiries please contact Sangoma Technologies Inc. by - - Hotline: 1-800-388-2475 (USA and Canada, toll free) - Phone: (905) 474-1990 ext: 106 - Fax: (905) 474-9223 - E-mail: dm@sangoma.com (David Mandelstam) - WWW: http://www.sangoma.com - - -INSTALLATION - -Please read the WanpipeForLinux.pdf manual on how to -install the WANPIPE tools and drivers properly. - - -After installing wanpipe package: /usr/local/wanrouter/doc. -On the ftp.sangoma.com : /linux/current_wanpipe/doc - - -COPYRIGHT AND LICENSING INFORMATION - -This program is free software; you can redistribute it and/or modify it under -the terms of the GNU General Public License as published by the Free Software -Foundation; either version 2, or (at your option) any later version. - -This program is distributed in the hope that it will be useful, but WITHOUT -ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS -FOR A PARTICULAR PURPOSE.

Success of the WANPIPE -together with the next major release of Linux kernel in summer 1996 commanded -adequate changes to the WANPIPE code to take full advantage of new Linux -features. - -Instead of continuing developing proprietary interface tied to Sangoma WAN -cards, we decided to separate all hardware-independent code into a separate -module and defined two levels of interfaces - one for user-level applications -and another for kernel-level WAN drivers. WANPIPE is now implemented as a -WAN driver compliant with the WAN Link Driver interface. Also a general -purpose WAN configuration utility and a set of shell scripts was developed to -support WAN router at the user level. - -Many useful ideas concerning hardware-independent interface implementation -were given by Mike McLagan and his implementation -of the Frame Relay router and drivers for Sangoma cards (dlci/sdla). - -With the new implementation of the APIs being incorporated into the WANPIPE, -a special thank goes to Alan Cox in providing insight into BSD sockets. - -Special thanks to all the WANPIPE users who performed field-testing, reported -bugs and made valuable comments and suggestions that help us to improve this -product. - - - -NEW IN THIS RELEASE - - o Updated the WANCFG utility - Calls the pppconfig to configure the PPPD - for async connections. - - o Added the PPPCONFIG utility - Used to configure the PPPD dameon for the - WANPIPE Async PPP and standard serial port. - The wancfg calls the pppconfig to configure - the pppd. - - o Fixed the PCI autodetect feature. - The SLOT 0 was used as an autodetect option - however, some high end PC's slot numbers start - from 0. - - o This release has been tested with the new backupd - daemon release. - - -PRODUCT COMPONENTS AND RELATED FILES - -/etc: (or user defined) - wanpipe1.conf default router configuration file -

At do_exit() time, all vmas are searched to see whether -they have a robust_head set. This approach has two fundamental problems -left: - - - it has quite complex locking and race scenarios. The vma-based - approach had been pending for years, but they are still not completely - reliable. - - - they have to scan _every_ vma at sys_exit() time, per thread! - -The second disadvantage is a real killer: pthread_exit() takes around 1 -microsecond on Linux, but with thousands (or tens of thousands) of vmas -every pthread_exit() takes a millisecond or more, also totally -destroying the CPU's L1 and L2 caches! - -This is very much noticeable even for normal process sys_exit_group() -calls: the kernel has to do the vma scanning unconditionally! (this is -because the kernel has no knowledge about how many robust futexes there -are to be cleaned up, because a robust futex might have been registered -in another task, and the futex variable might have been simply mmap()-ed -into this process's address space). - -This huge overhead forced the creation of CONFIG_FUTEX_ROBUST so that -normal kernels can turn it off, but worse than that: the overhead makes -robust futexes impractical for any type of generic Linux distribution. - -So something had to be done. - -New approach to robust futexes ------------------------------- - -At the heart of this new approach there is a per-thread private list of -robust locks that userspace is holding (maintained by glibc) - which -userspace list is registered with the kernel via a new syscall [this -registration happens at most once per thread lifetime]. At do_exit() -time, the kernel checks this user-space list: are there any robust futex -locks to be cleaned up? - -In the common case, at do_exit() time, there is no list registered, so -the cost of robust futexes is just a simple current->robust_list != NULL -comparison. If the thread has registered a list, then normally the list -is empty. If the thread/process crashed or terminated in some incorrect -way then the list might be non-empty: in this case the kernel carefully -walks the list [not trusting it], and marks all locks that are owned by -this thread with the FUTEX_OWNER_DIED bit, and wakes up one waiter (if -any). - -The list is guaranteed to be private and per-thread at do_exit() time, -so it can be accessed by the kernel in a lockless way. - -There is one race possible though: since adding to and removing from the -list is done after the futex is acquired by glibc, there is a few -instructions window for the thread (or process) to die there, leaving -the futex hung. To protect against this possibility, userspace (glibc) -also maintains a simple per-thread 'list_op_pending' field, to allow the -kernel to clean up if the thread dies after acquiring the lock, but just -before it could have added itself to the list. Glibc sets this -list_op_pending field before it tries to acquire the futex, and clears -it after the list-add (or list-remove) has finished. - -That's all that is needed - all the rest of robust-futex cleanup is done -in userspace [just like with the previous patches]. - -Ulrich Drepper has implemented the necessary glibc support for this new -mechanism, which fully enables robust mutexes. - -Key differences of this userspace-list based approach, compared to the -vma based method: - - - it's much, much faster: at thread exit time, there's no need to loop - over every vma (!), which the VM-based method has to do. Only a very - simple 'is the list empty' op is done. - - - no VM changes are needed - 'struct address_space' is left alone. - - - no registration of individual locks is needed: robust mutexes dont - need any extra per-lock syscalls. Robust mutexes thus become a very - lightweight primitive - so they dont force the application designer - to do a hard choice between performance and robustness - robust - mutexes are just as fast. - - - no per-lock kernel allocation happens. - - - no resource limits are needed. - - - no kernel-space recovery call (FUTEX_RECOVER) is needed. - - - the implementation and the locking is "obvious", and there are no - interactions with the VM. - -Performance ------------ - -I have benchmarked the time needed for the kernel to process a list of 1 -million (!) held locks, using the new method [on a 2GHz CPU]: - - - with FUTEX_WAIT set [contended mutex]: 130 msecs - - without FUTEX_WAIT set [uncontended mutex]: 30 msecs - -I have also measured an approach where glibc does the lock notification -[which it currently does for !pshared robust mutexes], and that took 256 -msecs - clearly slower, due to the 1 million FUTEX_WAKE syscalls -userspace had to do. - -(1 million held locks are unheard of - we expect at most a handful of -locks to be held at a time. Nevertheless it's nice to know that this -approach scales nicely.) - -Implementation details ----------------------- - -The patch adds two new syscalls: one to register the userspace list, and -one to query the registered list pointer: - - asmlinkage long - sys_set_robust_list(struct robust_list_head __user *head, - size_t len); - - asmlinkage long - sys_get_robust_list(int pid, struct robust_list_head __user **head_ptr, - size_t __user *len_ptr); - -List registration is very fast: the pointer is simply stored in -current->robust_list. [Note that in the future, if robust futexes become -widespread, we could extend sys_clone() to register a robust-list head -for new threads, without the need of another syscall.] - -So there is virtually zero overhead for tasks not using robust futexes, -and even for robust futex users, there is only one extra syscall per -thread lifetime, and the cleanup operation, if it happens, is fast and -straightforward. The kernel doesnt have any internal distinction between -robust and normal futexes. - -If a futex is found to be held at exit time, the kernel sets the -following bit of the futex word: - - #define FUTEX_OWNER_DIED 0x40000000 - -and wakes up the next futex waiter (if any). User-space does the rest of -the cleanup. - -Otherwise, robust futexes are acquired by glibc by putting the TID into -the futex field atomically. Waiters set the FUTEX_WAITERS bit: - - #define FUTEX_WAITERS 0x80000000 - -and the remaining bits are for the TID. - -Testing, architecture support ------------------------------ - -i've tested the new syscalls on x86 and x86_64, and have made sure the -parsing of the userspace list is robust [ ;-) ] even if the list is -deliberately corrupted. - -i386 and x86_64 syscalls are wired up at the moment, and Ulrich has -tested the new glibc code (on x86_64 and i386), and it works for his -robust-mutex testcases. - -All other architectures should build just fine too - but they wont have -the new syscalls yet. - -Architectures need to implement the new futex_atomic_cmpxchg_inatomic() -inline function before writing up the syscalls (that function returns --ENOSYS right now). diff --git a/Documentation/rt-mutex-design.txt b/Documentation/rt-mutex-design.txt deleted file mode 100644 index c472ffacc..000000000 --- a/Documentation/rt-mutex-design.txt +++ /dev/null @@ -1,781 +0,0 @@ -# -# Copyright (c) 2006 Steven Rostedt -# Licensed under the GNU Free Documentation License, Version 1.2 -# - -RT-mutex implementation design ------------------------------- - -This document tries to describe the design of the rtmutex.c implementation. -It doesn't describe the reasons why rtmutex.c exists. For that please see -Documentation/rt-mutex.txt. Although this document does explain problems -that happen without this code, but that is in the concept to understand -what the code actually is doing. - -The goal of this document is to help others understand the priority -inheritance (PI) algorithm that is used, as well as reasons for the -decisions that were made to implement PI in the manner that was done. - - -Unbounded Priority Inversion ----------------------------- - -Priority inversion is when a lower priority process executes while a higher -priority process wants to run. This happens for several reasons, and -most of the time it can't be helped. Anytime a high priority process wants -to use a resource that a lower priority process has (a mutex for example), -the high priority process must wait until the lower priority process is done -with the resource. This is a priority inversion. What we want to prevent -is something called unbounded priority inversion. That is when the high -priority process is prevented from running by a lower priority process for -an undetermined amount of time. - -The classic example of unbounded priority inversion is were you have three -processes, let's call them processes A, B, and C, where A is the highest -priority process, C is the lowest, and B is in between. A tries to grab a lock -that C owns and must wait and lets C run to release the lock. But in the -meantime, B executes, and since B is of a higher priority than C, it preempts C, -but by doing so, it is in fact preempting A which is a higher priority process. -Now there's no way of knowing how long A will be sleeping waiting for C -to release the lock, because for all we know, B is a CPU hog and will -never give C a chance to release the lock. This is called unbounded priority -inversion. - -Here's a little ASCII art to show the problem. - - grab lock L1 (owned by C) - | -A ---+ - C preempted by B - | -C +----+ - -B +--------> - B now keeps A from running. - - -Priority Inheritance (PI) -------------------------- - -There are several ways to solve this issue, but other ways are out of scope -for this document. Here we only discuss PI. - -PI is where a process inherits the priority of another process if the other -process blocks on a lock owned by the current process. To make this easier -to understand, let's use the previous example, with processes A, B, and C again. - -This time, when A blocks on the lock owned by C, C would inherit the priority -of A. So now if B becomes runnable, it would not preempt C, since C now has -the high priority of A. As soon as C releases the lock, it loses its -inherited priority, and A then can continue with the resource that C had. - -Terminology ------------ - -Here I explain some terminology that is used in this document to help describe -the design that is used to implement PI. - -PI chain - The PI chain is an ordered series of locks and processes that cause - processes to inherit priorities from a previous process that is - blocked on one of its locks. This is described in more detail - later in this document. - -mutex - In this document, to differentiate from locks that implement - PI and spin locks that are used in the PI code, from now on - the PI locks will be called a mutex. - -lock - In this document from now on, I will use the term lock when - referring to spin locks that are used to protect parts of the PI - algorithm. These locks disable preemption for UP (when - CONFIG_PREEMPT is enabled) and on SMP prevents multiple CPUs from - entering critical sections simultaneously. - -spin lock - Same as lock above. - -waiter - A waiter is a struct that is stored on the stack of a blocked - process. Since the scope of the waiter is within the code for - a process being blocked on the mutex, it is fine to allocate - the waiter on the process's stack (local variable). This - structure holds a pointer to the task, as well as the mutex that - the task is blocked on. It also has the plist node structures to - place the task in the waiter_list of a mutex as well as the - pi_list of a mutex owner task (described below). - - waiter is sometimes used in reference to the task that is waiting - on a mutex. This is the same as waiter->task. - -waiters - A list of processes that are blocked on a mutex. - -top waiter - The highest priority process waiting on a specific mutex. - -top pi waiter - The highest priority process waiting on one of the mutexes - that a specific process owns. - -Note: task and process are used interchangeably in this document, mostly to - differentiate between two processes that are being described together. - - -PI chain --------- - -The PI chain is a list of processes and mutexes that may cause priority -inheritance to take place. Multiple chains may converge, but a chain -would never diverge, since a process can't be blocked on more than one -mutex at a time. - -Example: - - Process: A, B, C, D, E - Mutexes: L1, L2, L3, L4 - - A owns: L1 - B blocked on L1 - B owns L2 - C blocked on L2 - C owns L3 - D blocked on L3 - D owns L4 - E blocked on L4 - -The chain would be: - - E->L4->D->L3->C->L2->B->L1->A - -To show where two chains merge, we could add another process F and -another mutex L5 where B owns L5 and F is blocked on mutex L5. - -The chain for F would be: - - F->L5->B->L1->A - -Since a process may own more than one mutex, but never be blocked on more than -one, the chains merge. - -Here we show both chains: - - E->L4->D->L3->C->L2-+ - | - +->B->L1->A - | - F->L5-+ - -For PI to work, the processes at the right end of these chains (or we may -also call it the Top of the chain) must be equal to or higher in priority -than the processes to the left or below in the chain. - -Also since a mutex may have more than one process blocked on it, we can -have multiple chains merge at mutexes. If we add another process G that is -blocked on mutex L2: - - G->L2->B->L1->A - -And once again, to show how this can grow I will show the merging chains -again. - - E->L4->D->L3->C-+ - +->L2-+ - | | - G-+ +->B->L1->A - | - F->L5-+ - - -Plist ------ - -Before I go further and talk about how the PI chain is stored through lists -on both mutexes and processes, I'll explain the plist. This is similar to -the struct list_head functionality that is already in the kernel. -The implementation of plist is out of scope for this document, but it is -very important to understand what it does. - -There are a few differences between plist and list, the most important one -being that plist is a priority sorted linked list. This means that the -priorities of the plist are sorted, such that it takes O(1) to retrieve the -highest priority item in the list. Obviously this is useful to store processes -based on their priorities. - -Another difference, which is important for implementation, is that, unlike -list, the head of the list is a different element than the nodes of a list. -So the head of the list is declared as struct plist_head and nodes that will -be added to the list are declared as struct plist_node. - - -Mutex Waiter List ------------------ - -Every mutex keeps track of all the waiters that are blocked on itself. The mutex -has a plist to store these waiters by priority. This list is protected by -a spin lock that is located in the struct of the mutex. This lock is called -wait_lock. Since the modification of the waiter list is never done in -interrupt context, the wait_lock can be taken without disabling interrupts. - - -Task PI List ------------- - -To keep track of the PI chains, each process has its own PI list. This is -a list of all top waiters of the mutexes that are owned by the process. -Note that this list only holds the top waiters and not all waiters that are -blocked on mutexes owned by the process. - -The top of the task's PI list is always the highest priority task that -is waiting on a mutex that is owned by the task. So if the task has -inherited a priority, it will always be the priority of the task that is -at the top of this list. - -This list is stored in the task structure of a process as a plist called -pi_list. This list is protected by a spin lock also in the task structure, -called pi_lock. This lock may also be taken in interrupt context, so when -locking the pi_lock, interrupts must be disabled. - - -Depth of the PI Chain ---------------------- - -The maximum depth of the PI chain is not dynamic, and could actually be -defined. But is very complex to figure it out, since it depends on all -the nesting of mutexes. Let's look at the example where we have 3 mutexes, -L1, L2, and L3, and four separate functions func1, func2, func3 and func4. -The following shows a locking order of L1->L2->L3, but may not actually -be directly nested that way. - -void func1(void) -{ - mutex_lock(L1); - - /* do anything */ - - mutex_unlock(L1); -} - -void func2(void) -{ - mutex_lock(L1); - mutex_lock(L2); - - /* do something */ - - mutex_unlock(L2); - mutex_unlock(L1); -} - -void func3(void) -{ - mutex_lock(L2); - mutex_lock(L3); - - /* do something else */ - - mutex_unlock(L3); - mutex_unlock(L2); -} - -void func4(void) -{ - mutex_lock(L3); - - /* do something again */ - - mutex_unlock(L3); -} - -Now we add 4 processes that run each of these functions separately. -Processes A, B, C, and D which run functions func1, func2, func3 and func4 -respectively, and such that D runs first and A last. With D being preempted -in func4 in the "do something again" area, we have a locking that follows: - -D owns L3 - C blocked on L3 - C owns L2 - B blocked on L2 - B owns L1 - A blocked on L1 - -And thus we have the chain A->L1->B->L2->C->L3->D. - -This gives us a PI depth of 4 (four processes), but looking at any of the -functions individually, it seems as though they only have at most a locking -depth of two. So, although the locking depth is defined at compile time, -it still is very difficult to find the possibilities of that depth. - -Now since mutexes can be defined by user-land applications, we don't want a DOS -type of application that nests large amounts of mutexes to create a large -PI chain, and have the code holding spin locks while looking at a large -amount of data. So to prevent this, the implementation not only implements -a maximum lock depth, but also only holds at most two different locks at a -time, as it walks the PI chain. More about this below. - - -Mutex owner and flags ---------------------- - -The mutex structure contains a pointer to the owner of the mutex. If the -mutex is not owned, this owner is set to NULL. Since all architectures -have the task structure on at least a four byte alignment (and if this is -not true, the rtmutex.c code will be broken!), this allows for the two -least significant bits to be used as flags. This part is also described -in Documentation/rt-mutex.txt, but will also be briefly described here. - -Bit 0 is used as the "Pending Owner" flag. This is described later. -Bit 1 is used as the "Has Waiters" flags. This is also described later - in more detail, but is set whenever there are waiters on a mutex. - - -cmpxchg Tricks --------------- - -Some architectures implement an atomic cmpxchg (Compare and Exchange). This -is used (when applicable) to keep the fast path of grabbing and releasing -mutexes short. - -cmpxchg is basically the following function performed atomically: - -unsigned long _cmpxchg(unsigned long *A, unsigned long *B, unsigned long *C) -{ - unsigned long T = *A; - if (*A == *B) { - *A = *C; - } - return T; -} -#define cmpxchg(a,b,c) _cmpxchg(&a,&b,&c) - -This is really nice to have, since it allows you to only update a variable -if the variable is what you expect it to be. You know if it succeeded if -the return value (the old value of A) is equal to B. - -The macro rt_mutex_cmpxchg is used to try to lock and unlock mutexes. If -the architecture does not support CMPXCHG, then this macro is simply set -to fail every time. But if CMPXCHG is supported, then this will -help out extremely to keep the fast path short. - -The use of rt_mutex_cmpxchg with the flags in the owner field help optimize -the system for architectures that support it. This will also be explained -later in this document. - - -Priority adjustments --------------------- - -The implementation of the PI code in rtmutex.c has several places that a -process must adjust its priority. With the help of the pi_list of a -process this is rather easy to know what needs to be adjusted. - -The functions implementing the task adjustments are rt_mutex_adjust_prio, -__rt_mutex_adjust_prio (same as the former, but expects the task pi_lock -to already be taken), rt_mutex_get_prio, and rt_mutex_setprio. - -rt_mutex_getprio and rt_mutex_setprio are only used in __rt_mutex_adjust_prio. - -rt_mutex_getprio returns the priority that the task should have. Either the -task's own normal priority, or if a process of a higher priority is waiting on -a mutex owned by the task, then that higher priority should be returned. -Since the pi_list of a task holds an order by priority list of all the top -waiters of all the mutexes that the task owns, rt_mutex_getprio simply needs -to compare the top pi waiter to its own normal priority, and return the higher -priority back. - -(Note: if looking at the code, you will notice that the lower number of - prio is returned. This is because the prio field in the task structure - is an inverse order of the actual priority. So a "prio" of 5 is - of higher priority than a "prio" of 10.) - -__rt_mutex_adjust_prio examines the result of rt_mutex_getprio, and if the -result does not equal the task's current priority, then rt_mutex_setprio -is called to adjust the priority of the task to the new priority. -Note that rt_mutex_setprio is defined in kernel/sched.c to implement the -actual change in priority. - -It is interesting to note that __rt_mutex_adjust_prio can either increase -or decrease the priority of the task. In the case that a higher priority -process has just blocked on a mutex owned by the task, __rt_mutex_adjust_prio -would increase/boost the task's priority. But if a higher priority task -were for some reason to leave the mutex (timeout or signal), this same function -would decrease/unboost the priority of the task. That is because the pi_list -always contains the highest priority task that is waiting on a mutex owned -by the task, so we only need to compare the priority of that top pi waiter -to the normal priority of the given task. - - -High level overview of the PI chain walk ----------------------------------------- - -The PI chain walk is implemented by the function rt_mutex_adjust_prio_chain. - -The implementation has gone through several iterations, and has ended up -with what we believe is the best. It walks the PI chain by only grabbing -at most two locks at a time, and is very efficient. - -The rt_mutex_adjust_prio_chain can be used either to boost or lower process -priorities. - -rt_mutex_adjust_prio_chain is called with a task to be checked for PI -(de)boosting (the owner of a mutex that a process is blocking on), a flag to -check for deadlocking, the mutex that the task owns, and a pointer to a waiter -that is the process's waiter struct that is blocked on the mutex (although this -parameter may be NULL for deboosting). - -For this explanation, I will not mention deadlock detection. This explanation -will try to stay at a high level. - -When this function is called, there are no locks held. That also means -that the state of the owner and lock can change when entered into this function. - -Before this function is called, the task has already had rt_mutex_adjust_prio -performed on it. This means that the task is set to the priority that it -should be at, but the plist nodes of the task's waiter have not been updated -with the new priorities, and that this task may not be in the proper locations -in the pi_lists and wait_lists that the task is blocked on. This function -solves all that. - -A loop is entered, where task is the owner to be checked for PI changes that -was passed by parameter (for the first iteration). The pi_lock of this task is -taken to prevent any more changes to the pi_list of the task. This also -prevents new tasks from completing the blocking on a mutex that is owned by this -task. - -If the task is not blocked on a mutex then the loop is exited. We are at -the top of the PI chain. - -A check is now done to see if the original waiter (the process that is blocked -on the current mutex) is the top pi waiter of the task. That is, is this -waiter on the top of the task's pi_list. If it is not, it either means that -there is another process higher in priority that is blocked on one of the -mutexes that the task owns, or that the waiter has just woken up via a signal -or timeout and has left the PI chain. In either case, the loop is exited, since -we don't need to do any more changes to the priority of the current task, or any -task that owns a mutex that this current task is waiting on. A priority chain -walk is only needed when a new top pi waiter is made to a task. - -The next check sees if the task's waiter plist node has the priority equal to -the priority the task is set at. If they are equal, then we are done with -the loop. Remember that the function started with the priority of the -task adjusted, but the plist nodes that hold the task in other processes -pi_lists have not been adjusted. - -Next, we look at the mutex that the task is blocked on. The mutex's wait_lock -is taken. This is done by a spin_trylock, because the locking order of the -pi_lock and wait_lock goes in the opposite direction. If we fail to grab the -lock, the pi_lock is released, and we restart the loop. - -Now that we have both the pi_lock of the task as well as the wait_lock of -the mutex the task is blocked on, we update the task's waiter's plist node -that is located on the mutex's wait_list. - -Now we release the pi_lock of the task. - -Next the owner of the mutex has its pi_lock taken, so we can update the -task's entry in the owner's pi_list. If the task is the highest priority -process on the mutex's wait_list, then we remove the previous top waiter -from the owner's pi_list, and replace it with the task. - -Note: It is possible that the task was the current top waiter on the mutex, - in which case the task is not yet on the pi_list of the waiter. This - is OK, since plist_del does nothing if the plist node is not on any - list. - -If the task was not the top waiter of the mutex, but it was before we -did the priority updates, that means we are deboosting/lowering the -task. In this case, the task is removed from the pi_list of the owner, -and the new top waiter is added. - -Lastly, we unlock both the pi_lock of the task, as well as the mutex's -wait_lock, and continue the loop again. On the next iteration of the -loop, the previous owner of the mutex will be the task that will be -processed. - -Note: One might think that the owner of this mutex might have changed - since we just grab the mutex's wait_lock. And one could be right. - The important thing to remember is that the owner could not have - become the task that is being processed in the PI chain, since - we have taken that task's pi_lock at the beginning of the loop. - So as long as there is an owner of this mutex that is not the same - process as the tasked being worked on, we are OK. - - Looking closely at the code, one might be confused. The check for the - end of the PI chain is when the task isn't blocked on anything or the - task's waiter structure "task" element is NULL. This check is - protected only by the task's pi_lock. But the code to unlock the mutex - sets the task's waiter structure "task" element to NULL with only - the protection of the mutex's wait_lock, which was not taken yet. - Isn't this a race condition if the task becomes the new owner? - - The answer is No! The trick is the spin_trylock of the mutex's - wait_lock. If we fail that lock, we release the pi_lock of the - task and continue the loop, doing the end of PI chain check again. - - In the code to release the lock, the wait_lock of the mutex is held - the entire time, and it is not let go when we grab the pi_lock of the - new owner of the mutex. So if the switch of a new owner were to happen - after the check for end of the PI chain and the grabbing of the - wait_lock, the unlocking code would spin on the new owner's pi_lock - but never give up the wait_lock. So the PI chain loop is guaranteed to - fail the spin_trylock on the wait_lock, release the pi_lock, and - try again. - - If you don't quite understand the above, that's OK. You don't have to, - unless you really want to make a proof out of it ;) - - -Pending Owners and Lock stealing --------------------------------- - -One of the flags in the owner field of the mutex structure is "Pending Owner". -What this means is that an owner was chosen by the process releasing the -mutex, but that owner has yet to wake up and actually take the mutex. - -Why is this important? Why can't we just give the mutex to another process -and be done with it? - -The PI code is to help with real-time processes, and to let the highest -priority process run as long as possible with little latencies and delays. -If a high priority process owns a mutex that a lower priority process is -blocked on, when the mutex is released it would be given to the lower priority -process. What if the higher priority process wants to take that mutex again. -The high priority process would fail to take that mutex that it just gave up -and it would need to boost the lower priority process to run with full -latency of that critical section (since the low priority process just entered -it). - -There's no reason a high priority process that gives up a mutex should be -penalized if it tries to take that mutex again. If the new owner of the -mutex has not woken up yet, there's no reason that the higher priority process -could not take that mutex away. - -To solve this, we introduced Pending Ownership and Lock Stealing. When a -new process is given a mutex that it was blocked on, it is only given -pending ownership. This means that it's the new owner, unless a higher -priority process comes in and tries to grab that mutex. If a higher priority -process does come along and wants that mutex, we let the higher priority -process "steal" the mutex from the pending owner (only if it is still pending) -and continue with the mutex. - - -Taking of a mutex (The walk through) ------------------------------------- - -OK, now let's take a look at the detailed walk through of what happens when -taking a mutex. - -The first thing that is tried is the fast taking of the mutex. This is -done when we have CMPXCHG enabled (otherwise the fast taking automatically -fails). Only when the owner field of the mutex is NULL can the lock be -taken with the CMPXCHG and nothing else needs to be done. - -If there is contention on the lock, whether it is owned or pending owner -we go about the slow path (rt_mutex_slowlock). - -The slow path function is where the task's waiter structure is created on -the stack. This is because the waiter structure is only needed for the -scope of this function. The waiter structure holds the nodes to store -the task on the wait_list of the mutex, and if need be, the pi_list of -the owner. - -The wait_lock of the mutex is taken since the slow path of unlocking the -mutex also takes this lock. - -We then call try_to_take_rt_mutex. This is where the architecture that -does not implement CMPXCHG would always grab the lock (if there's no -contention). - -try_to_take_rt_mutex is used every time the task tries to grab a mutex in the -slow path. The first thing that is done here is an atomic setting of -the "Has Waiters" flag of the mutex's owner field. Yes, this could really -be false, because if the the mutex has no owner, there are no waiters and -the current task also won't have any waiters. But we don't have the lock -yet, so we assume we are going to be a waiter. The reason for this is to -play nice for those architectures that do have CMPXCHG. By setting this flag -now, the owner of the mutex can't release the mutex without going into the -slow unlock path, and it would then need to grab the wait_lock, which this -code currently holds. So setting the "Has Waiters" flag forces the owner -to synchronize with this code. - -Now that we know that we can't have any races with the owner releasing the -mutex, we check to see if we can take the ownership. This is done if the -mutex doesn't have a owner, or if we can steal the mutex from a pending -owner. Let's look at the situations we have here. - - 1) Has owner that is pending - ---------------------------- - - The mutex has a owner, but it hasn't woken up and the mutex flag - "Pending Owner" is set. The first check is to see if the owner isn't the - current task. This is because this function is also used for the pending - owner to grab the mutex. When a pending owner wakes up, it checks to see - if it can take the mutex, and this is done if the owner is already set to - itself. If so, we succeed and leave the function, clearing the "Pending - Owner" bit. - - If the pending owner is not current, we check to see if the current priority is - higher than the pending owner. If not, we fail the function and return. - - There's also something special about a pending owner. That is a pending owner - is never blocked on a mutex. So there is no PI chain to worry about. It also - means that if the mutex doesn't have any waiters, there's no accounting needed - to update the pending owner's pi_list, since we only worry about processes - blocked on the current mutex. - - If there are waiters on this mutex, and we just stole the ownership, we need - to take the top waiter, remove it from the pi_list of the pending owner, and - add it to the current pi_list. Note that at this moment, the pending owner - is no longer on the list of waiters. This is fine, since the pending owner - would add itself back when it realizes that it had the ownership stolen - from itself. When the pending owner tries to grab the mutex, it will fail - in try_to_take_rt_mutex if the owner field points to another process. - - 2) No owner - ----------- - - If there is no owner (or we successfully stole the lock), we set the owner - of the mutex to current, and set the flag of "Has Waiters" if the current - mutex actually has waiters, or we clear the flag if it doesn't. See, it was - OK that we set that flag early, since now it is cleared. - - 3) Failed to grab ownership - --------------------------- - - The most interesting case is when we fail to take ownership. This means that - there exists an owner, or there's a pending owner with equal or higher - priority than the current task. - -We'll continue on the failed case. - -If the mutex has a timeout, we set up a timer to go off to break us out -of this mutex if we failed to get it after a specified amount of time. - -Now we enter a loop that will continue to try to take ownership of the mutex, or -fail from a timeout or signal. - -Once again we try to take the mutex. This will usually fail the first time -in the loop, since it had just failed to get the mutex. But the second time -in the loop, this would likely succeed, since the task would likely be -the pending owner. - -If the mutex is TASK_INTERRUPTIBLE a check for signals and timeout is done -here. - -The waiter structure has a "task" field that points to the task that is blocked -on the mutex. This field can be NULL the first time it goes through the loop -or if the task is a pending owner and had it's mutex stolen. If the "task" -field is NULL then we need to set up the accounting for it. - -Task blocks on mutex --------------------- - -The accounting of a mutex and process is done with the waiter structure of -the process. The "task" field is set to the process, and the "lock" field -to the mutex. The plist nodes are initialized to the processes current -priority. - -Since the wait_lock was taken at the entry of the slow lock, we can safely -add the waiter to the wait_list. If the current process is the highest -priority process currently waiting on this mutex, then we remove the -previous top waiter process (if it exists) from the pi_list of the owner, -and add the current process to that list. Since the pi_list of the owner -has changed, we call rt_mutex_adjust_prio on the owner to see if the owner -should adjust its priority accordingly. - -If the owner is also blocked on a lock, and had its pi_list changed -(or deadlock checking is on), we unlock the wait_lock of the mutex and go ahead -and run rt_mutex_adjust_prio_chain on the owner, as described earlier. - -Now all locks are released, and if the current process is still blocked on a -mutex (waiter "task" field is not NULL), then we go to sleep (call schedule). - -Waking up in the loop ---------------------- - -The schedule can then wake up for a few reasons. - 1) we were given pending ownership of the mutex. - 2) we received a signal and was TASK_INTERRUPTIBLE - 3) we had a timeout and was TASK_INTERRUPTIBLE - -In any of these cases, we continue the loop and once again try to grab the -ownership of the mutex. If we succeed, we exit the loop, otherwise we continue -and on signal and timeout, will exit the loop, or if we had the mutex stolen -we just simply add ourselves back on the lists and go back to sleep. - -Note: For various reasons, because of timeout and signals, the steal mutex - algorithm needs to be careful. This is because the current process is - still on the wait_list. And because of dynamic changing of priorities, - especially on SCHED_OTHER tasks, the current process can be the - highest priority task on the wait_list. - -Failed to get mutex on Timeout or Signal ----------------------------------------- - -If a timeout or signal occurred, the waiter's "task" field would not be -NULL and the task needs to be taken off the wait_list of the mutex and perhaps -pi_list of the owner. If this process was a high priority process, then -the rt_mutex_adjust_prio_chain needs to be executed again on the owner, -but this time it will be lowering the priorities. - - -Unlocking the Mutex -------------------- - -The unlocking of a mutex also has a fast path for those architectures with -CMPXCHG. Since the taking of a mutex on contention always sets the -"Has Waiters" flag of the mutex's owner, we use this to know if we need to -take the slow path when unlocking the mutex. If the mutex doesn't have any -waiters, the owner field of the mutex would equal the current process and -the mutex can be unlocked by just replacing the owner field with NULL. - -If the owner field has the "Has Waiters" bit set (or CMPXCHG is not available), -the slow unlock path is taken. - -The first thing done in the slow unlock path is to take the wait_lock of the -mutex. This synchronizes the locking and unlocking of the mutex. - -A check is made to see if the mutex has waiters or not. On architectures that -do not have CMPXCHG, this is the location that the owner of the mutex will -determine if a waiter needs to be awoken or not. On architectures that -do have CMPXCHG, that check is done in the fast path, but it is still needed -in the slow path too. If a waiter of a mutex woke up because of a signal -or timeout between the time the owner failed the fast path CMPXCHG check and -the grabbing of the wait_lock, the mutex may not have any waiters, thus the -owner still needs to make this check. If there are no waiters than the mutex -owner field is set to NULL, the wait_lock is released and nothing more is -needed. - -If there are waiters, then we need to wake one up and give that waiter -pending ownership. - -On the wake up code, the pi_lock of the current owner is taken. The top -waiter of the lock is found and removed from the wait_list of the mutex -as well as the pi_list of the current owner. The task field of the new -pending owner's waiter structure is set to NULL, and the owner field of the -mutex is set to the new owner with the "Pending Owner" bit set, as well -as the "Has Waiters" bit if there still are other processes blocked on the -mutex. - -The pi_lock of the previous owner is released, and the new pending owner's -pi_lock is taken. Remember that this is the trick to prevent the race -condition in rt_mutex_adjust_prio_chain from adding itself as a waiter -on the mutex. - -We now clear the "pi_blocked_on" field of the new pending owner, and if -the mutex still has waiters pending, we add the new top waiter to the pi_list -of the pending owner. - -Finally we unlock the pi_lock of the pending owner and wake it up. - - -Contact -------- - -For updates on this document, please email Steven Rostedt - - -Credits -------- - -Author: Steven Rostedt - -Reviewers: Ingo Molnar, Thomas Gleixner, Thomas Duetsch, and Randy Dunlap - -Updates -------- - -This document was originally written for 2.6.17-rc3-mm1 diff --git a/Documentation/rt-mutex.txt b/Documentation/rt-mutex.txt deleted file mode 100644 index 243393d88..000000000 --- a/Documentation/rt-mutex.txt +++ /dev/null @@ -1,79 +0,0 @@ -RT-mutex subsystem with PI support ----------------------------------- - -RT-mutexes with priority inheritance are used to support PI-futexes, -which enable pthread_mutex_t priority inheritance attributes -(PTHREAD_PRIO_INHERIT). [See Documentation/pi-futex.txt for more details -about PI-futexes.] - -This technology was developed in the -rt tree and streamlined for -pthread_mutex support. - -Basic principles: ------------------ - -RT-mutexes extend the semantics of simple mutexes by the priority -inheritance protocol. - -A low priority owner of a rt-mutex inherits the priority of a higher -priority waiter until the rt-mutex is released. If the temporarily -boosted owner blocks on a rt-mutex itself it propagates the priority -boosting to the owner of the other rt_mutex it gets blocked on. The -priority boosting is immediately removed once the rt_mutex has been -unlocked. - -This approach allows us to shorten the block of high-prio tasks on -mutexes which protect shared resources. Priority inheritance is not a -magic bullet for poorly designed applications, but it allows -well-designed applications to use userspace locks in critical parts of -an high priority thread, without losing determinism. - -The enqueueing of the waiters into the rtmutex waiter list is done in -priority order. For same priorities FIFO order is chosen. For each -rtmutex, only the top priority waiter is enqueued into the owner's -priority waiters list. This list too queues in priority order. Whenever -the top priority waiter of a task changes (for example it timed out or -got a signal), the priority of the owner task is readjusted. [The -priority enqueueing is handled by "plists", see include/linux/plist.h -for more details.] - -RT-mutexes are optimized for fastpath operations and have no internal -locking overhead when locking an uncontended mutex or unlocking a mutex -without waiters. The optimized fastpath operations require cmpxchg -support. [If that is not available then the rt-mutex internal spinlock -is used] - -The state of the rt-mutex is tracked via the owner field of the rt-mutex -structure: - -rt_mutex->owner holds the task_struct pointer of the owner. Bit 0 and 1 -are used to keep track of the "owner is pending" and "rtmutex has -waiters" state. - - owner bit1 bit0 - NULL 0 0 mutex is free (fast acquire possible) - NULL 0 1 invalid state - NULL 1 0 Transitional state* - NULL 1 1 invalid state - taskpointer 0 0 mutex is held (fast release possible) - taskpointer 0 1 task is pending owner - taskpointer 1 0 mutex is held and has waiters - taskpointer 1 1 task is pending owner and mutex has waiters - -Pending-ownership handling is a performance optimization: -pending-ownership is assigned to the first (highest priority) waiter of -the mutex, when the mutex is released. The thread is woken up and once -it starts executing it can acquire the mutex. Until the mutex is taken -by it (bit 0 is cleared) a competing higher priority thread can "steal" -the mutex which puts the woken up thread back on the waiters list. - -The pending-ownership optimization is especially important for the -uninterrupted workflow of high-prio tasks which repeatedly -takes/releases locks that have lower-prio waiters. Without this -optimization the higher-prio thread would ping-pong to the lower-prio -task [because at unlock time we always assign a new owner]. - -(*) The "mutex has waiters" bit gets set to take the lock. If the lock -doesn't already have an owner, this bit is quickly cleared if there are -no waiters.

Use this instead of passing memory_start, memory_end - around all over the place. - - * scsi.h, st.c, sr.c, sd.c, sg.c: Change *_init1 functions to use - scsi_init_malloc, remove all arguments, no return value. - - * scsi.h: Remove index field from Scsi_Device and Scsi_Cmnd - structs. - - * scsi.c (scsi_dev_init): Set up for scsi_init_malloc. - (scan_scsis): Get SDpnt from scsi_init_malloc, and refresh - when we discover a device. Free pointer before returning. - Change scsi_devices into a linked list. - - * scsi.c (scan_scsis): Change to only scan one host. - (scsi_dev_init): Loop over all detected hosts, and scan them. - - * hosts.c (scsi_init_free): Change so that number of extra bytes - is stored in struct, and we do not have to pass it each time. - - * hosts.h: Change Scsi_Host_Template struct to include "next" and - "release" functions. Initialize to NULL in all low level - adapters. - - * hosts.c: Rename scsi_hosts to builtin_scsi_hosts, create linked - list scsi_hosts, linked together with the new "next" field. - -Wed Jul 6 05:45:02 1994 Eric Youngdale (eric@esp22) - - * Linux 1.1.25 released. - - * aha152x.c: Changes from Juergen - cleanups and updates. - - * sd.c, sr.c: Use new check_media_change and revalidate - file_operations fields. - - * st.c, st.h: Add changes from Kai Makisara, dated Jun 22. - - * hosts.h: Change SG_ALL back to 0xff. Apparently soft error - in /dev/brain resulted in having this bumped up. - Change first parameter in bios_param function to be Disk * instead - of index into rscsi_disks. - - * sd_ioctl.c: Pass pointer to rscsi_disks element instead of index - to array. - - * sd.h: Add struct name "scsi_disk" to typedef for Scsi_Disk. - - * scsi.c: Remove redundant Maxtor XT8760S from blacklist. - In scsi_reset, add printk when DEBUG defined. - - * All low level drivers: Modify definitions of bios_param in - appropriate way. - -Thu Jun 16 10:31:59 1994 Eric Youngdale (eric@esp22) - - * Linux 1.1.20 released. - - * scsi_ioctl.c: Only pass down the actual number of characters - required to scsi_do_cmd, not the one rounded up to a even number - of sectors. - - * ultrastor.c: Changes from Caleb Epstein for 24f cards. Support - larger SG lists. - - * ultrastor.c: Changes from me - use scsi_register to register - host. Add some consistency checking, - -Wed Jun 1 21:12:13 1994 Eric Youngdale (eric@esp22) - - * Linux 1.1.19 released. - - * scsi.h: Add new return code for reset() function: - SCSI_RESET_PUNT. - - * scsi.c: Make SCSI_RESET_PUNT the same as SCSI_RESET_WAKEUP for - now. - - * aha1542.c: If the command responsible for the reset is not - pending, return SCSI_RESET_PUNT. - - * aha1740.c, buslogic.c, wd7000.c, ultrastor.c: Return - SCSI_RESET_PUNT instead of SCSI_RESET_SNOOZE. - -Tue May 31 19:36:01 1994 Eric Youngdale (eric@esp22) - - * buslogic.c: Do not print out message about "must be Adaptec" - if we have detected a buslogic card. Print out a warning message - if we are configuring for >16Mb, since the 445S at board level - D or earlier does not work right. The "D" level board can be made - to work by flipping an undocumented switch, but this is too subtle. - - Changes based upon patches in Yggdrasil distribution. - - * sg.c, sg.h: Return sense data to user. - - * aha1542.c, aha1740.c, buslogic.c: Do not panic if - sense buffer is wrong size. - - * hosts.c: Test for ultrastor card before any of the others. - - * scsi.c: Allow boot-time option for max_scsi_luns=? so that - buggy firmware has an easy work-around. - -Sun May 15 20:24:34 1994 Eric Youngdale (eric@esp22) - - * Linux 1.1.15 released. - - Post-codefreeze thaw... - - * buslogic.[c,h]: New driver from David Gentzel. - - * hosts.h: Add use_clustering field to explicitly say whether - clustering should be used for devices attached to this host - adapter. The buslogic board apparently supports large SG lists, - but it is apparently faster if sd.c condenses this into a smaller - list. - - * sd.c: Use this field instead of heuristic. - - * All host adapter include files: Add appropriate initializer for - use_clustering field. - - * scsi.h: Add #defines for return codes for the abort and reset - functions. There are now a specific set of return codes to fully - specify all of the possible things that the low-level adapter - could do. - - * scsi.c: Act based upon return codes from abort/reset functions. - - * All host adapter abort/reset functions: Return new return code. - - * Add code in scsi.c to help debug timeouts. Use #define - DEBUG_TIMEOUT to enable this. - - * scsi.c: If the host->irq field is set, use - disable_irq/enable_irq before calling queuecommand if we - are not already in an interrupt. Reduce races, and we - can be sloppier about cli/sti in the interrupt routines now - (reduce interrupt latency). - - * constants.c: Fix some things to eliminate warnings. Add some - sense descriptions that were omitted before. - - * aha1542.c: Watch for SCRD from host adapter - if we see it, set - a flag. Currently we only print out the number of pending - commands that might need to be restarted. - - * aha1542.c (aha1542_abort): Look for lost interrupts, OGMB still - full, and attempt to recover. Otherwise give up. - - * aha1542.c (aha1542_reset): Try BUS DEVICE RESET, and then pass - DID_RESET back up to the upper level code for all commands running - on this target (even on different LUNs). - -Sat May 7 14:54:01 1994 - - * Linux 1.1.12 released. - - * st.c, st.h: New version from Kai.

These routines fall -under a NDA, and may therefor not be distributed as source; however, its use -is completely optional. - -You can build this code either into your kernel, or as a module. I recommend -the latter, since it makes troubleshooting a lot easier. The built-in -microphone is supported through the USB Audio class. - -When you load the module you can set some default settings for the -camera; some programs depend on a particular image-size or -format and -don't know how to set it properly in the driver. The options are: - -size - Can be one of 'sqcif', 'qsif', 'qcif', 'sif', 'cif' or - 'vga', for an image size of resp. 128x96, 160x120, 176x144, - 320x240, 352x288 and 640x480 (of course, only for those cameras that - support these resolutions). - -fps - Specifies the desired framerate. Is an integer in the range of 4-30. - -fbufs - This paramter specifies the number of internal buffers to use for storing - frames from the cam. This will help if the process that reads images from - the cam is a bit slow or momentarely busy. However, on slow machines it - only introduces lag, so choose carefully. The default is 3, which is - reasonable. You can set it between 2 and 5. - -mbufs - This is an integer between 1 and 10. It will tell the module the number of - buffers to reserve for mmap(), VIDIOCCGMBUF, VIDIOCMCAPTURE and friends. - The default is 2, which is adequate for most applications (double - buffering). - - Should you experience a lot of 'Dumping frame...' messages during - grabbing with a tool that uses mmap(), you might want to increase if. - However, it doesn't really buffer images, it just gives you a bit more - slack when your program is behind. But you need a multi-threaded or - forked program to really take advantage of these buffers. - - The absolute maximum is 10, but don't set it too high! Every buffer takes - up 460 KB of RAM, so unless you have a lot of memory setting this to - something more than 4 is an absolute waste. This memory is only - allocated during open(), so nothing is wasted when the camera is not in - use. - -power_save - When power_save is enabled (set to 1), the module will try to shut down - the cam on close() and re-activate on open(). This will save power and - turn off the LED. Not all cameras support this though (the 645 and 646 - don't have power saving at all), and some models don't work either (they - will shut down, but never wake up). Consider this experimental. By - default this option is disabled. - -compression (only useful with the plugin) - With this option you can control the compression factor that the camera - uses to squeeze the image through the USB bus. You can set the - parameter between 0 and 3: - 0 = prefer uncompressed images; if the requested mode is not available - in an uncompressed format, the driver will silently switch to low - compression. - 1 = low compression. - 2 = medium compression. - 3 = high compression. - - High compression takes less bandwidth of course, but it could also - introduce some unwanted artefacts. The default is 2, medium compression. - See the FAQ on the website for an overview of which modes require - compression. - - The compression parameter does not apply to the 645 and 646 cameras - and OEM models derived from those (only a few). Most cams honour this - parameter. - -leds - This settings takes 2 integers, that define the on/off time for the LED - (in milliseconds). One of the interesting things that you can do with - this is let the LED blink while the camera is in use. This: - - leds=500,500 - - will blink the LED once every second. But with: - - leds=0,0 - - the LED never goes on, making it suitable for silent surveillance. - - By default the camera's LED is on solid while in use, and turned off - when the camera is not used anymore. - - This parameter works only with the ToUCam range of cameras (720, 730, 740, - 750) and OEMs. For other cameras this command is silently ignored, and - the LED cannot be controlled. - - Finally: this parameters does not take effect UNTIL the first time you - open the camera device. Until then, the LED remains on. - -dev_hint - A long standing problem with USB devices is their dynamic nature: you - never know what device a camera gets assigned; it depends on module load - order, the hub configuration, the order in which devices are plugged in, - and the phase of the moon (i.e. it can be random). With this option you - can give the driver a hint as to what video device node (/dev/videoX) it - should use with a specific camera. This is also handy if you have two - cameras of the same model. - - A camera is specified by its type (the number from the camera model, - like PCA645, PCVC750VC, etc) and optionally the serial number (visible - in /proc/bus/usb/devices). A hint consists of a string with the following - format: - - [type[.serialnumber]:]node - - The square brackets mean that both the type and the serialnumber are - optional, but a serialnumber cannot be specified without a type (which - would be rather pointless). The serialnumber is separated from the type - by a '.'; the node number by a ':'. - - This somewhat cryptic syntax is best explained by a few examples: - - dev_hint=3,5 The first detected cam gets assigned - /dev/video3, the second /dev/video5. Any - other cameras will get the first free - available slot (see below). - - dev_hint=645:1,680:2 The PCA645 camera will get /dev/video1, - and a PCVC680 /dev/video2. - - dev_hint=645.0123:3,645.4567:0 The PCA645 camera with serialnumber - 0123 goes to /dev/video3, the same - camera model with the 4567 serial - gets /dev/video0. - - dev_hint=750:1,4,5,6 The PCVC750 camera will get /dev/video1, the - next 3 Philips cams will use /dev/video4 - through /dev/video6. - - Some points worth knowing: - - Serialnumbers are case sensitive and must be written full, including - leading zeroes (it's treated as a string). - - If a device node is already occupied, registration will fail and - the webcam is not available. - - You can have up to 64 video devices; be sure to make enough device - nodes in /dev if you want to spread the numbers (this does not apply - to devfs). After /dev/video9 comes /dev/video10 (not /dev/videoA). - - If a camera does not match any dev_hint, it will simply get assigned - the first available device node, just as it used to be. - -trace - In order to better detect problems, it is now possible to turn on a - 'trace' of some of the calls the module makes; it logs all items in your - kernel log at debug level. - - The trace variable is a bitmask; each bit represents a certain feature. - If you want to trace something, look up the bit value(s) in the table - below, add the values together and supply that to the trace variable. - - Value Value Description Default - (dec) (hex) - 1 0x1 Module initialization; this will log messages On - while loading and unloading the module - - 2 0x2 probe() and disconnect() traces On - - 4 0x4 Trace open() and close() calls Off - - 8 0x8 read(), mmap() and associated ioctl() calls Off - - 16 0x10 Memory allocation of buffers, etc. Off - - 32 0x20 Showing underflow, overflow and Dumping frame On - messages - - 64 0x40 Show viewport and image sizes Off - - 128 0x80 PWCX debugging Off - - For example, to trace the open() & read() fuctions, sum 8 + 4 = 12, - so you would supply trace=12 during insmod or modprobe.

Event flags register interest in particular -events; when an event happens and an engine has the right event flag -set, it gets a callback. Action flags change the normal behavior of -the thread. The action flags available are: - - UTRACE_ACTION_QUIESCE - - The thread will stay quiescent (see below). - As long as any engine asserts the QUIESCE action flag, - the thread will not resume running in user mode. - (Usually it will be in TASK_TRACED state.) - Nothing will wake the thread up except for SIGKILL - (and implicit SIGKILLs such as a core dump in - another thread sharing the same address space, or a - group exit or fatal signal in another thread in the - same thread group). - - UTRACE_ACTION_SINGLESTEP - - When the thread runs, it will run one instruction - and then trap. (Exiting a system call or entering a - signal handler is considered "an instruction" for this.) - This can be used only if ARCH_HAS_SINGLE_STEP #define'd - by and evaluates to nonzero. - - UTRACE_ACTION_BLOCKSTEP - - When the thread runs, it will run until the next branch, - and then trap. (Exiting a system call or entering a - signal handler is considered a branch for this.) - When the SINGLESTEP flag is set, BLOCKSTEP has no effect. - This is only available on some machines (actually none yet). - This can be used only if ARCH_HAS_BLOCK_STEP #define'd - by and evaluates to nonzero. - - UTRACE_ACTION_NOREAP - - When the thread exits or stops for job control, its - parent process will not receive a SIGCHLD and the - parent's wait calls will not wake up or report the - child as dead. A well-behaved tracing engine does not - want to interfere with the parent's normal notifications. - This is provided mainly for the ptrace compatibility - code to implement the traditional behavior. - -Event flags are specified using the macro UTRACE_EVENT(TYPE). -Each event type is associated with a report_* callback in struct -utrace_engine_ops. A tracing engine can leave unused callbacks NULL. -The only callbacks required are those used by the event flags it sets. - -Many engines can be attached to each thread. When a thread has an -event, each engine gets a report_* callback if it has set the event flag -for that event type. Engines are called in the order they attached. - -Each callback takes arguments giving the details of the particular -event. The first two arguments two every callback are the struct -utrace_attached_engine and struct task_struct pointers for the engine -and the thread producing the event. Usually this will be the current -thread that is running the callback functions. - -The return value of report_* callbacks is a bitmask. Some bits are -common to all callbacks, and some are particular to that callback and -event type. The value zero (UTRACE_ACTION_RESUME) always means the -simplest thing: do what would have happened with no tracing engine here. -These are the flags that can be set in any report_* return value: - - UTRACE_ACTION_NEWSTATE - - Update the action state flags, described above. Those - bits from the return value (UTRACE_ACTION_STATE_MASK) - replace those bits in the engine's flags. This has the - same effect as calling utrace_set_flags, but is a more - efficient short-cut. To change the event flags, you must - call utrace_set_flags. - - UTRACE_ACTION_DETACH - - Detach this engine. This has the effect of calling - utrace_detach, but is a more efficient short-cut. - - UTRACE_ACTION_HIDE - - Hide this event from other tracing engines. This is - only appropriate to do when the event was induced by - some action of this engine, such as a breakpoint trap. - Some events cannot be hidden, since every engine has to - know about them: exit, death, reap. - -The return value bits in UTRACE_ACTION_OP_MASK indicate a change to the -normal behavior of the event taking place. If zero, the thread does -whatever that event normally means. For report_signal, other values -control the disposition of the signal. - - - Quiescence - ---------- - -To control another thread and access its state, it must be "quiescent". -This means that it is stopped and won't start running again while we access -it. A quiescent thread is stopped in a place close to user mode, where the -user state can be accessed safely; either it's about to return to user -mode, or it's just entered the kernel from user mode, or it has already -finished exiting (TASK_ZOMBIE). Setting the UTRACE_ACTION_QUIESCE action -flag will force the attached thread to become quiescent soon. After -setting the flag, an engine must wait for an event callback when the thread -becomes quiescent. The thread may be running on another CPU, or may be in -an uninterruptible wait. When it is ready to be examined, it will make -callbacks to engines that set the UTRACE_EVENT(QUIESCE) event flag. - -As long as some engine has UTRACE_ACTION_QUIESCE set, then the thread will -remain stopped. SIGKILL will wake it up, but it will not run user code. -When the flag is cleared via utrace_set_flags or a callback return value, -the thread starts running again. - -During the event callbacks (report_*), the thread in question makes the -callback from a safe place. It is not quiescent, but it can safely access -its own state. Callbacks can access thread state directly without setting -the QUIESCE action flag. If a callback does want to prevent the thread -from resuming normal execution, it *must* use the QUIESCE action state -rather than simply blocking; see "Core Events & Callbacks", below. - - - Thread control - ------ ------- - -These calls must be made on a quiescent thread (or the current thread): - - int utrace_inject_signal(struct task_struct *target, - struct utrace_attached_engine *engine, - u32 action, siginfo_t *info, - const struct k_sigaction *ka); - -Cause a specified signal delivery in the target thread.

The -info and ka arguments serve the same purposes as their counterparts in -a report_signal callback. - - const struct utrace_regset * - utrace_regset(struct task_struct *target, - struct utrace_attached_engine *engine, - const struct utrace_regset_view *view, - int which); - -Get access to machine state for the thread.

But to be a good citizen, -callback code should never block for long periods. It is fine to block in -kmalloc and the like, but never wait for i/o or for user mode to do -something. If you need the thread to wait, set UTRACE_ACTION_QUIESCE and -return from the callback quickly. When your i/o finishes or whatever, you -can use utrace_set_flags to resume the thread. - -Well-behaved callbacks are important to maintain two essential properties -of the interface. The first of these is that unrelated tracing engines not -interfere with each other. If your engine's event callback does not return -quickly, then another engine won't get the event notification in a timely -manner. The second important property is that tracing be as noninvasive as -possible to the normal operation of the system overall and of the traced -thread in particular. That is, attached tracing engines should not perturb -a thread's behavior, except to the extent that changing its user-visible -state is explicitly what you want to do. (Obviously some perturbation is -unavoidable, primarily timing changes, ranging from small delays due to the -overhead of tracing, to arbitrary pauses in user code execution when a user -stops a thread with a debugger for examination. When doing asynchronous -utrace_attach to a thread doing a system call, more troublesome side -effects are possible.) Even when you explicitly want the pertrubation of -making the traced thread block, just blocking directly in your callback has -more unwanted effects. For example, the CLONE event callbacks are called -when the new child thread has been created but not yet started running; the -child can never be scheduled until the CLONE tracing callbacks return. -(This allows engines tracing the parent to attach to the child.) If a -CLONE event callback blocks the parent thread, it also prevents the child -thread from running (even to process a SIGKILL). If what you want is to -make both the parent and child block, then use utrace_attach on the child -and then set the QUIESCE action state flag on both threads. A more crucial -problem with blocking in callbacks is that it can prevent SIGKILL from -working. A thread that is blocking due to UTRACE_ACTION_QUIESCE will still -wake up and die immediately when sent a SIGKILL, as all threads should. -Relying on the utrace infrastructure rather than on private synchronization -calls in event callbacks is an important way to help keep tracing robustly -noninvasive. - - -EVENT(REAP) Dead thread has been reaped -Callback: - void (*report_reap)(struct utrace_attached_engine *engine, - struct task_struct *tsk); - -This means the parent called wait, or else this was a detached thread or -a process whose parent ignores SIGCHLD. This cannot happen while the -UTRACE_ACTION_NOREAP flag is set. This is the only callback you are -guaranteed to get (if you set the flag). - -Unlike other callbacks, this can be called from the parent's context -rather than from the traced thread itself--it must not delay the parent by -blocking. This callback is different from all others, it returns void. -Once you get this callback, your engine is automatically detached and you -cannot access this thread or use this struct utrace_attached_engine handle -any longer. This is the place to clean up your data structures and -synchronize with your code that might try to make utrace_* calls using this -engine data structure. The struct is still valid during this callback, -but will be freed soon after it returns (via RCU). - -In all other callbacks, the return value is as described above. -The common UTRACE_ACTION_* flags in the return value are always observed. -Unless otherwise specified below, other bits in the return value are ignored. - - -EVENT(QUIESCE) Thread is quiescent -Callback: - u32 (*report_quiesce)(struct utrace_attached_engine *engine, - struct task_struct *tsk); - -This is the least interesting callback. It happens at any safe spot, -including after any other event callback.

The new process is fully formed, but not yet -running. During this callback, other tracing engines are prevented from -using utrace_attach asynchronously on the child, so that engines tracing -the parent get the first opportunity to attach. After this callback -returns, the child will start and the parent's system call will return. -If CLONE_VFORK is set, the parent will block before returning. - -EVENT(VFORK_DONE) Finished waiting for CLONE_VFORK child -Callback: - u32 (*report_vfork_done)(struct utrace_attached_engine *engine, - struct task_struct *parent, pid_t child_pid); - -Event reported for parent using CLONE_VFORK or vfork system call. -The child has died or exec'd, so the vfork parent has unblocked -and is about to return child_pid. - -UTRACE_EVENT(EXEC) Completed exec -Callback: - u32 (*report_exec)(struct utrace_attached_engine *engine, - struct task_struct *tsk, - const struct linux_binprm *bprm, - struct pt_regs *regs); - -An execve system call has succeeded and the new program is about to -start running. The initial user register state is handy to be tweaked -directly, or utrace_regset can be used for full machine state access. - -UTRACE_EVENT(EXIT) Thread is exiting -Callback: - u32 (*report_exit)(struct utrace_attached_engine *engine, - struct task_struct *tsk, - long orig_code, long *code); - -The thread is exiting and cannot be prevented from doing so, but all its -state is still live. The *code value will be the wait result seen by -the parent, and can be changed by this engine or others. The orig_code -value is the real status, not changed by any tracing engine. - -UTRACE_EVENT(DEATH) Thread has finished exiting -Callback: - u32 (*report_death)(struct utrace_attached_engine *engine, - struct task_struct *tsk); - -The thread is really dead now. If the UTRACE_ACTION_NOREAP flag is set -after this callback, it remains an unreported zombie. Otherwise, it might -be reaped by its parent, or self-reap immediately.

Introduction - - This is a driver for STMicroelectronics's CPiA2 (second generation -Colour Processor Interface ASIC) based cameras. This camera outputs an MJPEG -stream at up to vga size. It implements the Video4Linux interface as much as -possible. Since the V4L interface does not support compressed formats, only -an mjpeg enabled application can be used with the camera. We have modified the -gqcam application to view this stream. - - The driver is implemented as two kernel modules. The cpia2 module -contains the camera functions and the V4L interface. The cpia2_usb module -contains usb specific functions. The main reason for this was the size of the -module was getting out of hand, so I separted them. It is not likely that -there will be a parallel port version. - -FEATURES: - - Supports cameras with the Vision stv6410 (CIF) and stv6500 (VGA) cmos - sensors. I only have the vga sensor, so can't test the other. - - Image formats: VGA, QVGA, CIF, QCIF, and a number of sizes in between. - VGA and QVGA are the native image sizes for the VGA camera. CIF is done - in the coprocessor by scaling QVGA. All other sizes are done by clipping. - - Palette: YCrCb, compressed with MJPEG. - - Some compression parameters are settable. - - Sensor framerate is adjustable (up to 30 fps CIF, 15 fps VGA). - - Adjust brightness, color, contrast while streaming. - - Flicker control settable for 50 or 60 Hz mains frequency. - -2. Making and installing the stv672 driver modules: - - Requirements: - ------------- - This should work with 2.4 (2.4.23 and later) and 2.6 kernels, but has -only been tested on 2.6. Video4Linux must be either compiled into the kernel or -available as a module. Video4Linux2 is automatically detected and made -available at compile time. - - Compiling: - ---------- - As root, do a make install. This will compile and install the modules -into the media/video directory in the module tree. For 2.4 kernels, use -Makefile_2.4 (aka do make -f Makefile_2.4 install). - - Setup: - ------ - Use 'modprobe cpia2' to load and 'modprobe -r cpia2' to unload. This -may be done automatically by your distribution. - -3. Driver options - - Option Description - ------ ----------- - video_nr video device to register (0=/dev/video0, etc) - range -1 to 64. default is -1 (first available) - If you have more than 1 camera, this MUST be -1. - buffer_size Size for each frame buffer in bytes (default 68k) - num_buffers Number of frame buffers (1-32, default 3) - alternate USB Alternate (2-7, default 7) - flicker_freq Frequency for flicker reduction(50 or 60, default 60) - flicker_mode 0 to disable, or 1 to enable flicker reduction. - (default 0). This is only effective if the camera - uses a stv0672 coprocessor. - - Setting the options: - -------------------- - If you are using modules, edit /etc/modules.conf and add an options -line like this: - options cpia2 num_buffers=3 buffer_size=65535 - - If the driver is compiled into the kernel, at boot time specify them -like this: - cpia2.num_buffers=3 cpia2.buffer_size=65535 - - What buffer size should I use? - ------------------------------ - The maximum image size depends on the alternate you choose, and the -frame rate achieved by the camera. If the compression engine is able to -keep up with the frame rate, the maximum image size is given by the table -below. - The compression engine starts out at maximum compression, and will -increase image quality until it is close to the size in the table. As long -as the compression engine can keep up with the frame rate, after a short time -the images will all be about the size in the table, regardless of resolution. - At low alternate settings, the compression engine may not be able to -compress the image enough and will reduce the frame rate by producing larger -images. - The default of 68k should be good for most users. This will handle -any alternate at frame rates down to 15fps. For lower frame rates, it may -be necessary to increase the buffer size to avoid having frames dropped due -to insufficient space. - - Image size(bytes) - Alternate bytes/ms 15fps 30fps - 2 128 8533 4267 - 3 384 25600 12800 - 4 640 42667 21333 - 5 768 51200 25600 - 6 896 59733 29867 - 7 1023 68200 34100 - - How many buffers should I use? - ------------------------------ - For normal streaming, 3 should give the best results. With only 2, -it is possible for the camera to finish sending one image just after a -program has started reading the other. If this happens, the driver must drop -a frame. The exception to this is if you have a heavily loaded machine. In -this case use 2 buffers. You are probably not reading at the full frame rate. -If the camera can send multiple images before a read finishes, it could -overwrite the third buffer before the read finishes, leading to a corrupt -image. Single and double buffering have extra checks to avoid overwriting. - -4. Using the camera - - We are providing a modified gqcam application to view the output. In -order to avoid confusion, here it is called mview. There is also the qx5view -program which can also control the lights on the qx5 microscope. MJPEG Tools -(http://mjpeg.sourceforge.net) can also be used to record from the camera. - -5. Notes to developers: - - - This is a driver version stripped of the 2.4 back compatibility - and old MJPEG ioctl API. See cpia2.sf.net for 2.4 support. - -6. Thanks: - - - Peter Pregler , - Scott J.

This means it has a DMA -engine to efficiently transfer large volumes of data between the card and main -memory without requiring help from a CPU. Like most hardware, it must operate -on contiguous physical memory. This is difficult to come by in large quantities -on virtual memory machines. - -Therefore, it also supports a technique called "scatter-gather". The card can -transfer multiple buffers in one operation. Instead of allocating one large -contiguous buffer, the driver can allocate several smaller buffers. - -In practice, I've seen the average transfer to be roughly 80K, but transfers -above 128K were not uncommon, particularly at startup. The 128K figure is -important, because that is the largest block that the kernel can normally -allocate. Even still, 128K blocks are hard to come by, so the driver writer is -urged to choose a smaller block size and learn the scatter-gather technique. - -Mailbox #10 is reserved for DMA transfer information. - -Flow -==== - -This section describes, in general, the order of events when handling DMA -transfers. Detailed information follows this section. - -- The card raises the Encoder interrupt. -- The driver reads the transfer type, offset and size from Mailbox #10. -- The driver constructs the scatter-gather array from enough free dma buffers - to cover the size. -- The driver schedules the DMA transfer via the ScheduleDMAtoHost API call. -- The card raises the DMA Complete interrupt. -- The driver checks the DMA status register for any errors. -- The driver post-processes the newly transferred buffers. - -NOTE!

Host -addresses are the physical memory location of the target DMA buffer. - -Each S-G array element is a struct of three 32-bit words. The first word is -the source address, the second is the destination address. Both take up the -entire 32 bits. The lowest 16 bits of the third word is the transfer byte -count. The high-bit of the third word is the "last" flag. The last-flag tells -the card to raise the DMA_DONE interrupt. From hard personal experience, if -you forget to set this bit, the card will still "work" but the stream will -most likely get corrupted. - -The transfer count must be a multiple of 256.

Overview and features -======================== -This driver supports the video interface of the devices mounting the ET61X151 -or ET61X251 PC Camera Controllers. - -It's worth to note that Etoms Electronics has never collaborated with the -author during the development of this project; despite several requests, -Etoms Electronics also refused to release enough detailed specifications of -the video compression engine. - -The driver relies on the Video4Linux2 and USB core modules. It has been -designed to run properly on SMP systems as well. - -The latest version of the ET61X[12]51 driver can be found at the following URL: -http://www.linux-projects.org/ - -Some of the features of the driver are: - -- full compliance with the Video4Linux2 API (see also "Notes for V4L2 - application developers" paragraph); -- available mmap or read/poll methods for video streaming through isochronous - data transfers; -- automatic detection of image sensor; -- support for any window resolutions and optional panning within the maximum - pixel area of image sensor; -- image downscaling with arbitrary scaling factors from 1 and 2 in both - directions (see "Notes for V4L2 application developers" paragraph); -- two different video formats for uncompressed or compressed data in low or - high compression quality (see also "Notes for V4L2 application developers" - paragraph); -- full support for the capabilities of every possible image sensors that can - be connected to the ET61X[12]51 bridges, including, for istance, red, green, - blue and global gain adjustments and exposure control (see "Supported - devices" paragraph for details); -- use of default color settings for sunlight conditions; -- dynamic I/O interface for both ET61X[12]51 and image sensor control (see - "Optional device control through 'sysfs'" paragraph); -- dynamic driver control thanks to various module parameters (see "Module - parameters" paragraph); -- up to 64 cameras can be handled at the same time; they can be connected and - disconnected from the host many times without turning off the computer, if - the system supports hotplugging; -- no known bugs. - - -5. Module dependencies -====================== -For it to work properly, the driver needs kernel support for Video4Linux and -USB. - -The following options of the kernel configuration file must be enabled and -corresponding modules must be compiled: - - # Multimedia devices - # - CONFIG_VIDEO_DEV=m - -To enable advanced debugging functionality on the device through /sysfs: - - # Multimedia devices - # - CONFIG_VIDEO_ADV_DEBUG=y - - # USB support - # - CONFIG_USB=m - -In addition, depending on the hardware being used, the modules below are -necessary: - - # USB Host Controller Drivers - # - CONFIG_USB_EHCI_HCD=m - CONFIG_USB_UHCI_HCD=m - CONFIG_USB_OHCI_HCD=m - -And finally: - - # USB Multimedia devices - # - CONFIG_USB_ET61X251=m - - -6. Module loading -================= -To use the driver, it is necessary to load the "et61x251" module into memory -after every other module required: "videodev", "usbcore" and, depending on -the USB host controller you have, "ehci-hcd", "uhci-hcd" or "ohci-hcd". - -Loading can be done as shown below: - - [root@localhost home]# modprobe et61x251 - -At this point the devices should be recognized. You can invoke "dmesg" to -analyze kernel messages and verify that the loading process has gone well: - - [user@localhost home]$ dmesg - - -7. Module parameters -==================== -Module parameters are listed below: -------------------------------------------------------------------------------- -Name: video_nr -Type: short array (min = 0, max = 64) -Syntax: <-1|n[,...]> -Description: Specify V4L2 minor mode number: - -1 = use next available - n = use minor number n - You can specify up to 64 cameras this way. - For example: - video_nr=-1,2,-1 would assign minor number 2 to the second - registered camera and use auto for the first one and for every - other camera. -Default: -1 -------------------------------------------------------------------------------- -Name: force_munmap -Type: bool array (min = 0, max = 64) -Syntax: <0|1[,...]> -Description: Force the application to unmap previously mapped buffer memory - before calling any VIDIOC_S_CROP or VIDIOC_S_FMT ioctl's. Not - all the applications support this feature. This parameter is - specific for each detected camera. - 0 = do not force memory unmapping - 1 = force memory unmapping (save memory) -Default: 0 -------------------------------------------------------------------------------- -Name: frame_timeout -Type: uint array (min = 0, max = 64) -Syntax: -Description: Timeout for a video frame in seconds. This parameter is - specific for each detected camera. This parameter can be - changed at runtime thanks to the /sys filesystem interface. -Default: 2 -------------------------------------------------------------------------------- -Name: debug -Type: ushort -Syntax: -Description: Debugging information level, from 0 to 3: - 0 = none (use carefully) - 1 = critical errors - 2 = significant informations - 3 = more verbose messages - Level 3 is useful for testing only, when only one device - is used at the same time. It also shows some more informations - about the hardware being detected. This module parameter can be - changed at runtime thanks to the /sys filesystem interface. -Default: 2 -------------------------------------------------------------------------------- - - -8. Optional device control through "sysfs" -========================================== -If the kernel has been compiled with the CONFIG_VIDEO_ADV_DEBUG option enabled, -it is possible to read and write both the ET61X[12]51 and the image sensor -registers by using the "sysfs" filesystem interface. - -There are four files in the /sys/class/video4linux/videoX directory for each -registered camera: "reg", "val", "i2c_reg" and "i2c_val". The first two files -control the ET61X[12]51 bridge, while the other two control the sensor chip. -"reg" and "i2c_reg" hold the values of the current register index where the -following reading/writing operations are addressed at through "val" and -"i2c_val". Their use is not intended for end-users, unless you know what you -are doing. Remember that you must be logged in as root before writing to them. - -As an example, suppose we were to want to read the value contained in the -register number 1 of the sensor register table - which is usually the product -identifier - of the camera registered as "/dev/video0": - - [root@localhost #] cd /sys/class/video4linux/video0 - [root@localhost #] echo 1 > i2c_reg - [root@localhost #] cat i2c_val - -Note that if the sensor registers can not be read, "cat" will fail. -To avoid race conditions, all the I/O accesses to the files are serialized. - - -9. Supported devices -==================== -None of the names of the companies as well as their products will be mentioned -here. They have never collaborated with the author, so no advertising. - -From the point of view of a driver, what unambiguously identify a device are -its vendor and product USB identifiers.

Notes for V4L2 application developers -========================================= -This driver follows the V4L2 API specifications. In particular, it enforces two -rules: - -- exactly one I/O method, either "mmap" or "read", is associated with each -file descriptor. Once it is selected, the application must close and reopen the -device to switch to the other I/O method; - -- although it is not mandatory, previously mapped buffer memory should always -be unmapped before calling any "VIDIOC_S_CROP" or "VIDIOC_S_FMT" ioctl's. -The same number of buffers as before will be allocated again to match the size -of the new video frames, so you have to map the buffers again before any I/O -attempts on them. - -Consistently with the hardware limits, this driver also supports image -downscaling with arbitrary scaling factors from 1 and 2 in both directions. -However, the V4L2 API specifications don't correctly define how the scaling -factor can be chosen arbitrarily by the "negotiation" of the "source" and -"target" rectangles. To work around this flaw, we have added the convention -that, during the negotiation, whenever the "VIDIOC_S_CROP" ioctl is issued, the -scaling factor is restored to 1. - -This driver supports two different video formats: the first one is the "8-bit -Sequential Bayer" format and can be used to obtain uncompressed video data -from the device through the current I/O method, while the second one provides -"raw" compressed video data (without frame headers not related to the -compressed data). The current compression quality may vary from 0 to 1 and can -be selected or queried thanks to the VIDIOC_S_JPEGCOMP and VIDIOC_G_JPEGCOMP -V4L2 ioctl's. - - -11.

See http://www.xirlink.com/ -(renamed to http://www.veo.com), http://www.ibmpccamera.com, -or http://www.c-itnow.com/ for details and pictures. - -This very chipset ("X Chip", as marked at the factory) -is used in several other cameras, and they are supported -as well: - -- IBM NetCamera -- Veo Stingray - -The Linux driver was developed with camera with following -model number (or FCC ID): KSX-XVP510. This camera has three -interfaces, each with one endpoint (control, iso, iso). This -type of cameras is referred to as "model 1". These cameras are -no longer manufactured. - -Xirlink now manufactures new cameras which are somewhat different. -In particular, following models [FCC ID] belong to that category: - -XVP300 [KSX-X9903] -XVP600 [KSX-X9902] -XVP610 [KSX-X9902] - -(see http://www.xirlink.com/ibmpccamera/ for updates, they refer -to these new cameras by Windows driver dated 12-27-99, v3005 BETA) -These cameras have two interfaces, one endpoint in each (iso, bulk). -Such type of cameras is referred to as "model 2". They are supported -(with exception of 352x288 native mode). - -Some IBM NetCameras (Model 4) are made to generate only compressed -video streams. This is great for performance, but unfortunately -nobody knows how to decompress the stream :-( Therefore, these -cameras are *unsupported* and if you try to use one of those, all -you get is random colored horizontal streaks, not the image! -If you have one of those cameras, you probably should return it -to the store and get something that is supported. - -Tell me more about all that "model" business --------------------------------------------- - -I just invented model numbers to uniquely identify flavors of the -hardware/firmware that were sold. It was very confusing to use -brand names or some other internal numbering schemes. So I found -by experimentation that all Xirlink chipsets fall into four big -classes, and I called them "models". Each model is programmed in -its own way, and each model sends back the video in its own way. - -Quirks of Model 2 cameras: -------------------------- - -Model 2 does not have hardware contrast control. Corresponding V4L -control is implemented in software, which is not very nice to your -CPU, but at least it works. - -This driver provides 352x288 mode by switching the camera into -quasi-352x288 RGB mode (800 Kbits per frame) essentially limiting -this mode to 10 frames per second or less, in ideal conditions on -the bus (USB is shared, after all). The frame rate -has to be programmed very conservatively. Additional concern is that -frame rate depends on brightness setting; therefore the picture can -be good at one brightness and broken at another! I did not want to fix -the frame rate at slowest setting, but I had to move it pretty much down -the scale (so that framerate option barely matters). I also noticed that -camera after first powering up produces frames slightly faster than during -consecutive uses. All this means that if you use 352x288 (which is -default), be warned - you may encounter broken picture on first connect; -try to adjust brightness - brighter image is slower, so USB will be able -to send all data. However if you regularly use Model 2 cameras you may -prefer 176x144 which makes perfectly good I420, with no scaling and -lesser demands on USB (300 Kbits per second, or 26 frames per second). - -Another strange effect of 352x288 mode is the fine vertical grid visible -on some colored surfaces. I am sure it is caused by me not understanding -what the camera is trying to say. Blame trade secrets for that. - -The camera that I had also has a hardware quirk: if disconnected, -it needs few minutes to "relax" before it can be plugged in again -(poorly designed USB processor reset circuit?) - -[Veo Stingray with Product ID 0x800C is also Model 2, but I haven't -observed this particular flaw in it.] - -Model 2 camera can be programmed for very high sensitivity (even starlight -may be enough), this makes it convenient for tinkering with. The driver -code has enough comments to help a programmer to tweak the camera -as s/he feels necessary. - -WHAT YOU NEED: - -- A supported IBM PC (C-it) camera (model 1 or 2) - -- A Linux box with USB support (2.3/2.4; 2.2 w/backport may work) - -- A Video4Linux compatible frame grabber program such as xawtv. - -HOW TO COMPILE THE DRIVER: - -You need to compile the driver only if you are a developer -or if you want to make changes to the code. Most distributions -precompile all modules, so you can go directly to the next -section "HOW TO USE THE DRIVER". - -The ibmcam driver uses usbvideo helper library (module), -so if you are studying the ibmcam code you will be led there. - -The driver itself consists of only one file in usb/ directory: -ibmcam.c. This file is included into the Linux kernel build -process if you configure the kernel for CONFIG_USB_IBMCAM. -Run "make xconfig" and in USB section you will find the IBM -camera driver. Select it, save the configuration and recompile. - -HOW TO USE THE DRIVER: - -I recommend to compile driver as a module. This gives you an -easier access to its configuration. The camera has many more -settings than V4L can operate, so some settings are done using -module options. - -To begin with, on most modern Linux distributions the driver -will be automatically loaded whenever you plug the supported -camera in. Therefore, you don't need to do anything. However -if you want to experiment with some module parameters then -you can load and unload the driver manually, with camera -plugged in or unplugged. - -Typically module is installed with command 'modprobe', like this: - -# modprobe ibmcam framerate=1 - -Alternatively you can use 'insmod' in similar fashion: - -# insmod /lib/modules/2.x.y/usb/ibmcam.o framerate=1 - -Module can be inserted with camera connected or disconnected. - -The driver can have options, though some defaults are provided. - -Driver options: (* indicates that option is model-dependent) - -Name Type Range [default] Example --------------- -------------- -------------- ------------------ -debug Integer 0-9 [0] debug=1 -flags Integer 0-0xFF [0] flags=0x0d -framerate Integer 0-6 [2] framerate=1 -hue_correction Integer 0-255 [128] hue_correction=115 -init_brightness Integer 0-255 [128] init_brightness=100 -init_contrast Integer 0-255 [192] init_contrast=200 -init_color Integer 0-255 [128] init_color=130 -init_hue Integer 0-255 [128] init_hue=115 -lighting Integer 0-2* [1] lighting=2 -sharpness Integer 0-6* [4] sharpness=3 -size Integer 0-2* [2] size=1 - -Options for Model 2 only: - -Name Type Range [default] Example --------------- -------------- -------------- ------------------ -init_model2_rg Integer 0..255 [0x70] init_model2_rg=128 -init_model2_rg2 Integer 0..255 [0x2f] init_model2_rg2=50 -init_model2_sat Integer 0..255 [0x34] init_model2_sat=65 -init_model2_yb Integer 0..255 [0xa0] init_model2_yb=200 - -debug You don't need this option unless you are a developer. - If you are a developer then you will see in the code - what values do what. 0=off. - -flags This is a bit mask, and you can combine any number of - bits to produce what you want. Usually you don't want - any of extra features this option provides: - - FLAGS_RETRY_VIDIOCSYNC 1 This bit allows to retry failed - VIDIOCSYNC ioctls without failing. - Will work with xawtv, will not - with xrealproducer. Default is - not set. - FLAGS_MONOCHROME 2 Activates monochrome (b/w) mode. - FLAGS_DISPLAY_HINTS 4 Shows colored pixels which have - magic meaning to developers. - FLAGS_OVERLAY_STATS 8 Shows tiny numbers on screen, - useful only for debugging. - FLAGS_FORCE_TESTPATTERN 16 Shows blue screen with numbers. - FLAGS_SEPARATE_FRAMES 32 Shows each frame separately, as - it was received from the camera. - Default (not set) is to mix the - preceding frame in to compensate - for occasional loss of Isoc data - on high frame rates. - FLAGS_CLEAN_FRAMES 64 Forces "cleanup" of each frame - prior to use; relevant only if - FLAGS_SEPARATE_FRAMES is set. - Default is not to clean frames, - this is a little faster but may - produce flicker if frame rate is - too high and Isoc data gets lost. - FLAGS_NO_DECODING 128 This flag turns the video stream - decoder off, and dumps the raw - Isoc data from the camera into - the reading process. Useful to - developers, but not to users. - -framerate This setting controls frame rate of the camera. This is - an approximate setting (in terms of "worst" ... "best") - because camera changes frame rate depending on amount - of light available. Setting 0 is slowest, 6 is fastest. - Beware - fast settings are very demanding and may not - work well with all video sizes. Be conservative. - -hue_correction This highly optional setting allows to adjust the - hue of the image in a way slightly different from - what usual "hue" control does. Both controls affect - YUV colorspace: regular "hue" control adjusts only - U component, and this "hue_correction" option similarly - adjusts only V component. However usually it is enough - to tweak only U or V to compensate for colored light or - color temperature; this option simply allows more - complicated correction when and if it is necessary. - -init_brightness These settings specify _initial_ values which will be -init_contrast used to set up the camera. If your V4L application has -init_color its own controls to adjust the picture then these -init_hue controls will be used too. These options allow you to - preconfigure the camera when it gets connected, before - any V4L application connects to it. Good for webcams. - -init_model2_rg These initial settings alter color balance of the -init_model2_rg2 camera on hardware level. All four settings may be used -init_model2_sat to tune the camera to specific lighting conditions. These -init_model2_yb settings only apply to Model 2 cameras. - -lighting This option selects one of three hardware-defined - photosensitivity settings of the camera. 0=bright light, - 1=Medium (default), 2=Low light. This setting affects - frame rate: the dimmer the lighting the lower the frame - rate (because longer exposition time is needed). The - Model 2 cameras allow values more than 2 for this option, - thus enabling extremely high sensitivity at cost of frame - rate, color saturation and imaging sensor noise. - -sharpness This option controls smoothing (noise reduction) - made by camera. Setting 0 is most smooth, setting 6 - is most sharp. Be aware that CMOS sensor used in the - camera is pretty noisy, so if you choose 6 you will - be greeted with "snowy" image. Default is 4. Model 2 - cameras do not support this feature. - -size This setting chooses one of several image sizes that are - supported by this driver. Cameras may support more, but - it's difficult to reverse-engineer all formats. - Following video sizes are supported: - - size=0 128x96 (Model 1 only) - size=1 160x120 - size=2 176x144 - size=3 320x240 (Model 2 only) - size=4 352x240 (Model 2 only) - size=5 352x288 - size=6 640x480 (Model 3 only) - - The 352x288 is the native size of the Model 1 sensor - array, so it's the best resolution the camera can - yield. The best resolution of Model 2 is 176x144, and - larger images are produced by stretching the bitmap. - Model 3 has sensor with 640x480 grid, and it works too, - but the frame rate will be exceptionally low (1-2 FPS); - it may be still OK for some applications, like security. - Choose the image size you need. The smaller image can - support faster frame rate. Default is 352x288. - -For more information and the Troubleshooting FAQ visit this URL: - - http://www.linux-usb.org/ibmcam/ - -WHAT NEEDS TO BE DONE: - -- The button on the camera is not used. I don't know how to get to it. - I know now how to read button on Model 2, but what to do with it? - -- Camera reports its status back to the driver; however I don't know - what returned data means.

Right click for the options dialog. - -MODULE PARAMETERS: - - You can set these with: insmod ov511 NAME=VALUE - There is currently no way to set these on a per-camera basis. - - NAME: autobright - TYPE: integer (Boolean) - DEFAULT: 1 - DESC: Brightness is normally under automatic control and can't be set - manually by the video app. Set to 0 for manual control. - - NAME: autogain - TYPE: integer (Boolean) - DEFAULT: 1 - DESC: Auto Gain Control enable. This feature is not yet implemented. - - NAME: autoexp - TYPE: integer (Boolean) - DEFAULT: 1 - DESC: Auto Exposure Control enable. This feature is not yet implemented. - - NAME: debug - TYPE: integer (0-6) - DEFAULT: 3 - DESC: Sets the threshold for printing debug messages. The higher the value, - the more is printed. The levels are cumulative, and are as follows: - 0=no debug messages - 1=init/detection/unload and other significant messages - 2=some warning messages - 3=config/control function calls - 4=most function calls and data parsing messages - 5=highly repetitive mesgs - - NAME: snapshot - TYPE: integer (Boolean) - DEFAULT: 0 - DESC: Set to 1 to enable snapshot mode. read()/VIDIOCSYNC will block until - the snapshot button is pressed. Note: enabling this mode disables - /proc/video/ov511//button - - NAME: cams - TYPE: integer (1-4 for OV511, 1-31 for OV511+) - DEFAULT: 1 - DESC: Number of cameras allowed to stream simultaneously on a single bus. - Values higher than 1 reduce the data rate of each camera, allowing two - or more to be used at once. If you have a complicated setup involving - both OV511 and OV511+ cameras, trial-and-error may be necessary for - finding the optimum setting. - - NAME: compress - TYPE: integer (Boolean) - DEFAULT: 0 - DESC: Set this to 1 to turn on the camera's compression engine. This can - potentially increase the frame rate at the expense of quality, if you - have a fast CPU. You must load the proper compression module for your - camera before starting your application (ov511_decomp or ov518_decomp). - - NAME: testpat - TYPE: integer (Boolean) - DEFAULT: 0 - DESC: This configures the camera's sensor to transmit a colored test-pattern - instead of an image. This does not work correctly yet. - - NAME: dumppix - TYPE: integer (0-2) - DEFAULT: 0 - DESC: Dumps raw pixel data and skips post-processing and format conversion. - It is for debugging purposes only. Options are: - 0: Disable (default) - 1: Dump raw data from camera, excluding headers and trailers - 2: Dumps data exactly as received from camera - - NAME: led - TYPE: integer (0-2) - DEFAULT: 1 (Always on) - DESC: Controls whether the LED (the little light) on the front of the camera - is always off (0), always on (1), or only on when driver is open (2). - This is not supported with the OV511, and might only work with certain - cameras (ones that actually have the LED wired to the control pin, and - not just hard-wired to be on all the time). - - NAME: dump_bridge - TYPE: integer (Boolean) - DEFAULT: 0 - DESC: Dumps the bridge (OV511[+] or OV518[+]) register values to the system - log. Only useful for serious debugging/development purposes. - - NAME: dump_sensor - TYPE: integer (Boolean) - DEFAULT: 0 - DESC: Dumps the sensor register values to the system log. Only useful for - serious debugging/development purposes. - - NAME: printph - TYPE: integer (Boolean) - DEFAULT: 0 - DESC: Setting this to 1 will dump the first 12 bytes of each isoc frame. This - is only useful if you are trying to debug problems with the isoc data - stream (i.e.: camera initializes, but vidcat hangs until Ctrl-C). Be - warned that this dumps a large number of messages to your kernel log. - - NAME: phy, phuv, pvy, pvuv, qhy, qhuv, qvy, qvuv - TYPE: integer (0-63 for phy and phuv, 0-255 for rest) - DEFAULT: OV511 default values - DESC: These are registers 70h - 77h of the OV511, which control the - prediction ranges and quantization thresholds of the compressor, for - the Y and UV channels in the horizontal and vertical directions. See - the OV511 or OV511+ data sheet for more detailed descriptions. These - normally do not need to be changed. - - NAME: lightfreq - TYPE: integer (0, 50, or 60) - DEFAULT: 0 (use sensor default) - DESC: Sets the sensor to match your lighting frequency. This can reduce the - appearance of "banding", i.e. horizontal lines or waves of light and - dark that are often caused by artificial lighting. Valid values are: - 0 - Use default (depends on sensor, most likely 60 Hz) - 50 - For European and Asian 50 Hz power - 60 - For American 60 Hz power - - NAME: bandingfilter - TYPE: integer (Boolean) - DEFAULT: 0 (off) - DESC: Enables the sensor´s banding filter exposure algorithm. This reduces - or stabilizes the "banding" caused by some artificial light sources - (especially fluorescent). You might have to set lightfreq correctly for - this to work right. As an added bonus, this sometimes makes it - possible to capture your monitor´s output. - - NAME: fastset - TYPE: integer (Boolean) - DEFAULT: 0 (off) - DESC: Allows picture settings (brightness, contrast, color, and hue) to take - effect immediately, even in the middle of a frame. This reduces the - time to change settings, but can ruin frames during the change. Only - affects OmniVision sensors. - - NAME: force_palette - TYPE: integer (Boolean) - DEFAULT: 0 (off) - DESC: Forces the palette (color format) to a specific value. If an - application requests a different palette, it will be rejected, thereby - forcing it to try others until it succeeds. This is useful for forcing - greyscale mode with a color camera, for example. Supported modes are: - 0 (Allows all the following formats) - 1 VIDEO_PALETTE_GREY (Linear greyscale) - 10 VIDEO_PALETTE_YUV420 (YUV 4:2:0 Planar) - 15 VIDEO_PALETTE_YUV420P (YUV 4:2:0 Planar, same as 10) - - NAME: backlight - TYPE: integer (Boolean) - DEFAULT: 0 (off) - DESC: Setting this flag changes the exposure algorithm for OmniVision sensors - such that objects in the camera's view (i.e. your head) can be clearly - seen when they are illuminated from behind. It reduces or eliminates - the sensor's auto-exposure function, so it should only be used when - needed. Additionally, it is only supported with the OV6620 and OV7620. - - NAME: unit_video - TYPE: Up to 16 comma-separated integers - DEFAULT: 0,0,0... (automatically assign the next available minor(s)) - DESC: You can specify up to 16 minor numbers to be assigned to ov511 devices. - For example, "unit_video=1,3" will make the driver use /dev/video1 and - /dev/video3 for the first two devices it detects. Additional devices - will be assigned automatically starting at the first available device - node (/dev/video0 in this case). Note that you cannot specify 0 as a - minor number. This feature requires kernel version 2.4.5 or higher. - - NAME: remove_zeros - TYPE: integer (Boolean) - DEFAULT: 0 (do not skip any incoming data) - DESC: Setting this to 1 will remove zero-padding from incoming data. This - will compensate for the blocks of corruption that can appear when the - camera cannot keep up with the speed of the USB bus (eg. at low frame - resolutions). This feature is always enabled when compression is on. - - NAME: mirror - TYPE: integer (Boolean) - DEFAULT: 0 (off) - DESC: Setting this to 1 will reverse ("mirror") the image horizontally. This - might be necessary if your camera has a custom lens assembly. This has - no effect with video capture devices. - - NAME: ov518_color - TYPE: integer (Boolean) - DEFAULT: 0 (off) - DESC: Enable OV518 color support. This is off by default since it doesn't - work most of the time. If you want to try it, you must also load - ov518_decomp with the "nouv=0" parameter. If you get improper colors or - diagonal lines through the image, restart your video app and try again. - Repeat as necessary. - -WORKING FEATURES: - o Color streaming/capture at most widths and heights that are multiples of 8. - o Monochrome (use force_palette=1 to enable) - o Setting/getting of saturation, contrast, brightness, and hue (only some of - them work the OV7620 and OV7620AE) - o /proc status reporting - o SAA7111A video capture support at 320x240 and 640x480 - o Compression support - o SMP compatibility - -HOW TO CONTACT ME: - -You can email me at mark@alpha.dyndns.org .

Overview and features -======================== -This driver attempts to support the video interface of the devices mounting the -SONiX SN9C101, SN9C102 and SN9C103 PC Camera Controllers. - -It's worth to note that SONiX has never collaborated with the author during the -development of this project, despite several requests for enough detailed -specifications of the register tables, compression engine and video data format -of the above chips. Nevertheless, these informations are no longer necessary, -becouse all the aspects related to these chips are known and have been -described in detail in this documentation. - -The driver relies on the Video4Linux2 and USB core modules. It has been -designed to run properly on SMP systems as well. - -The latest version of the SN9C10x driver can be found at the following URL: -http://www.linux-projects.org/ - -Some of the features of the driver are: - -- full compliance with the Video4Linux2 API (see also "Notes for V4L2 - application developers" paragraph); -- available mmap or read/poll methods for video streaming through isochronous - data transfers; -- automatic detection of image sensor; -- support for built-in microphone interface; -- support for any window resolutions and optional panning within the maximum - pixel area of image sensor; -- image downscaling with arbitrary scaling factors from 1, 2 and 4 in both - directions (see "Notes for V4L2 application developers" paragraph); -- two different video formats for uncompressed or compressed data in low or - high compression quality (see also "Notes for V4L2 application developers" - and "Video frame formats" paragraphs); -- full support for the capabilities of many of the possible image sensors that - can be connected to the SN9C10x bridges, including, for istance, red, green, - blue and global gain adjustments and exposure (see "Supported devices" - paragraph for details); -- use of default color settings for sunlight conditions; -- dynamic I/O interface for both SN9C10x and image sensor control and - monitoring (see "Optional device control through 'sysfs'" paragraph); -- dynamic driver control thanks to various module parameters (see "Module - parameters" paragraph); -- up to 64 cameras can be handled at the same time; they can be connected and - disconnected from the host many times without turning off the computer, if - the system supports hotplugging; -- no known bugs. - - -5. Module dependencies -====================== -For it to work properly, the driver needs kernel support for Video4Linux and -USB. - -The following options of the kernel configuration file must be enabled and -corresponding modules must be compiled: - - # Multimedia devices - # - CONFIG_VIDEO_DEV=m - -To enable advanced debugging functionality on the device through /sysfs: - - # Multimedia devices - # - CONFIG_VIDEO_ADV_DEBUG=y - - # USB support - # - CONFIG_USB=m - -In addition, depending on the hardware being used, the modules below are -necessary: - - # USB Host Controller Drivers - # - CONFIG_USB_EHCI_HCD=m - CONFIG_USB_UHCI_HCD=m - CONFIG_USB_OHCI_HCD=m - -The SN9C103 controller also provides a built-in microphone interface. It is -supported by the USB Audio driver thanks to the ALSA API: - - # Sound - # - CONFIG_SOUND=y - - # Advanced Linux Sound Architecture - # - CONFIG_SND=m - - # USB devices - # - CONFIG_SND_USB_AUDIO=m - -And finally: - - # USB Multimedia devices - # - CONFIG_USB_SN9C102=m - - -6. Module loading -================= -To use the driver, it is necessary to load the "sn9c102" module into memory -after every other module required: "videodev", "usbcore" and, depending on -the USB host controller you have, "ehci-hcd", "uhci-hcd" or "ohci-hcd". - -Loading can be done as shown below: - - [root@localhost home]# modprobe sn9c102 - -At this point the devices should be recognized. You can invoke "dmesg" to -analyze kernel messages and verify that the loading process has gone well: - - [user@localhost home]$ dmesg - - -7. Module parameters -==================== -Module parameters are listed below: -------------------------------------------------------------------------------- -Name: video_nr -Type: short array (min = 0, max = 64) -Syntax: <-1|n[,...]> -Description: Specify V4L2 minor mode number: - -1 = use next available - n = use minor number n - You can specify up to 64 cameras this way. - For example: - video_nr=-1,2,-1 would assign minor number 2 to the second - recognized camera and use auto for the first one and for every - other camera. -Default: -1 -------------------------------------------------------------------------------- -Name: force_munmap -Type: bool array (min = 0, max = 64) -Syntax: <0|1[,...]> -Description: Force the application to unmap previously mapped buffer memory - before calling any VIDIOC_S_CROP or VIDIOC_S_FMT ioctl's. Not - all the applications support this feature. This parameter is - specific for each detected camera. - 0 = do not force memory unmapping - 1 = force memory unmapping (save memory) -Default: 0 -------------------------------------------------------------------------------- -Name: frame_timeout -Type: uint array (min = 0, max = 64) -Syntax: -Description: Timeout for a video frame in seconds. This parameter is - specific for each detected camera. This parameter can be - changed at runtime thanks to the /sys filesystem interface. -Default: 2 -------------------------------------------------------------------------------- -Name: debug -Type: ushort -Syntax: -Description: Debugging information level, from 0 to 3: - 0 = none (use carefully) - 1 = critical errors - 2 = significant informations - 3 = more verbose messages - Level 3 is useful for testing only, when only one device - is used. It also shows some more informations about the - hardware being detected. This parameter can be changed at - runtime thanks to the /sys filesystem interface. -Default: 2 -------------------------------------------------------------------------------- - - -8. Optional device control through "sysfs" [1] -========================================== -If the kernel has been compiled with the CONFIG_VIDEO_ADV_DEBUG option enabled, -it is possible to read and write both the SN9C10x and the image sensor -registers by using the "sysfs" filesystem interface. - -Every time a supported device is recognized, a write-only file named "green" is -created in the /sys/class/video4linux/videoX directory. You can set the green -channel's gain by writing the desired value to it. The value may range from 0 -to 15 for SN9C101 or SN9C102 bridges, from 0 to 127 for SN9C103 bridges. -Similarly, only for SN9C103 controllers, blue and red gain control files are -available in the same directory, for which accepted values may range from 0 to -127. - -There are other four entries in the directory above for each registered camera: -"reg", "val", "i2c_reg" and "i2c_val". The first two files control the -SN9C10x bridge, while the other two control the sensor chip. "reg" and -"i2c_reg" hold the values of the current register index where the following -reading/writing operations are addressed at through "val" and "i2c_val". Their -use is not intended for end-users. Note that "i2c_reg" and "i2c_val" will not -be created if the sensor does not actually support the standard I2C protocol or -its registers are not 8-bit long. Also, remember that you must be logged in as -root before writing to them. - -As an example, suppose we were to want to read the value contained in the -register number 1 of the sensor register table - which is usually the product -identifier - of the camera registered as "/dev/video0": - - [root@localhost #] cd /sys/class/video4linux/video0 - [root@localhost #] echo 1 > i2c_reg - [root@localhost #] cat i2c_val - -Note that "cat" will fail if sensor registers cannot be read. - -Now let's set the green gain's register of the SN9C101 or SN9C102 chips to 2: - - [root@localhost #] echo 0x11 > reg - [root@localhost #] echo 2 > val - -Note that the SN9C10x always returns 0 when some of its registers are read. -To avoid race conditions, all the I/O accesses to the above files are -serialized. - -The sysfs interface also provides the "frame_header" entry, which exports the -frame header of the most recent requested and captured video frame. The header -is always 18-bytes long and is appended to every video frame by the SN9C10x -controllers. As an example, this additional information can be used by the user -application for implementing auto-exposure features via software. - -The following table describes the frame header: - -Byte # Value Description ------- ----- ----------- -0x00 0xFF Frame synchronisation pattern. -0x01 0xFF Frame synchronisation pattern. -0x02 0x00 Frame synchronisation pattern. -0x03 0xC4 Frame synchronisation pattern. -0x04 0xC4 Frame synchronisation pattern. -0x05 0x96 Frame synchronisation pattern. -0x06 0xXX Unknown meaning. The exact value depends on the chip; - possible values are 0x00, 0x01 and 0x20. -0x07 0xXX Variable value, whose bits are ff00uzzc, where ff is a - frame counter, u is unknown, zz is a size indicator - (00 = VGA, 01 = SIF, 10 = QSIF) and c stands for - "compression enabled" (1 = yes, 0 = no). -0x08 0xXX Brightness sum inside Auto-Exposure area (low-byte). -0x09 0xXX Brightness sum inside Auto-Exposure area (high-byte). - For a pure white image, this number will be equal to 500 - times the area of the specified AE area. For images - that are not pure white, the value scales down according - to relative whiteness. -0x0A 0xXX Brightness sum outside Auto-Exposure area (low-byte). -0x0B 0xXX Brightness sum outside Auto-Exposure area (high-byte). - For a pure white image, this number will be equal to 125 - times the area outside of the specified AE area. For - images that are not pure white, the value scales down - according to relative whiteness. - according to relative whiteness. - -The following bytes are used by the SN9C103 bridge only: - -0x0C 0xXX Unknown meaning -0x0D 0xXX Unknown meaning -0x0E 0xXX Unknown meaning -0x0F 0xXX Unknown meaning -0x10 0xXX Unknown meaning -0x11 0xXX Unknown meaning - -The AE area (sx, sy, ex, ey) in the active window can be set by programming the -registers 0x1c, 0x1d, 0x1e and 0x1f of the SN9C10x controllers, where one unit -corresponds to 32 pixels. - -[1] Part of the meaning of the frame header has been documented by Bertrik - Sikken. - - -9. Supported devices -==================== -None of the names of the companies as well as their products will be mentioned -here.

Notes for V4L2 application developers -========================================= -This driver follows the V4L2 API specifications. In particular, it enforces two -rules: - -- exactly one I/O method, either "mmap" or "read", is associated with each -file descriptor. Once it is selected, the application must close and reopen the -device to switch to the other I/O method; - -- although it is not mandatory, previously mapped buffer memory should always -be unmapped before calling any "VIDIOC_S_CROP" or "VIDIOC_S_FMT" ioctl's. -The same number of buffers as before will be allocated again to match the size -of the new video frames, so you have to map the buffers again before any I/O -attempts on them. - -Consistently with the hardware limits, this driver also supports image -downscaling with arbitrary scaling factors from 1, 2 and 4 in both directions. -However, the V4L2 API specifications don't correctly define how the scaling -factor can be chosen arbitrarily by the "negotiation" of the "source" and -"target" rectangles. To work around this flaw, we have added the convention -that, during the negotiation, whenever the "VIDIOC_S_CROP" ioctl is issued, the -scaling factor is restored to 1. - -This driver supports two different video formats: the first one is the "8-bit -Sequential Bayer" format and can be used to obtain uncompressed video data -from the device through the current I/O method, while the second one provides -"raw" compressed video data (without frame headers not related to the -compressed data). The compression quality may vary from 0 to 1 and can be -selected or queried thanks to the VIDIOC_S_JPEGCOMP and VIDIOC_G_JPEGCOMP V4L2 -ioctl's. For maximum flexibility, both the default active video format and the -default compression quality depend on how the image sensor being used is -initialized (as described in the documentation of the API for the image sensors -supplied by this driver). - - -11. Video frame formats [1] -======================= -The SN9C10x PC Camera Controllers can send images in two possible video -formats over the USB: either native "Sequential RGB Bayer" or Huffman -compressed. The latter is used to achieve high frame rates. The current video -format may be selected or queried from the user application by calling the -VIDIOC_S_FMT or VIDIOC_G_FMT ioctl's, as described in the V4L2 API -specifications. - -The name "Sequential Bayer" indicates the organization of the red, green and -blue pixels in one video frame. Each pixel is associated with a 8-bit long -value and is disposed in memory according to the pattern shown below: - -B[0] G[1] B[2] G[3] ... B[m-2] G[m-1] -G[m] R[m+1] G[m+2] R[m+2] ... G[2m-2] R[2m-1] -... -... B[(n-1)(m-2)] G[(n-1)(m-1)] -... G[n(m-2)] R[n(m-1)] - -The above matrix also represents the sequential or progressive read-out mode of -the (n, m) Bayer color filter array used in many CCD/CMOS image sensors. - -One compressed video frame consists of a bitstream that encodes for every R, G, -or B pixel the difference between the value of the pixel itself and some -reference pixel value. Pixels are organised in the Bayer pattern and the Bayer -sub-pixels are tracked individually and alternatingly. For example, in the -first line values for the B and G1 pixels are alternatingly encoded, while in -the second line values for the G2 and R pixels are alternatingly encoded. - -The pixel reference value is calculated as follows: -- the 4 top left pixels are encoded in raw uncompressed 8-bit format; -- the value in the top two rows is the value of the pixel left of the current - pixel; -- the value in the left column is the value of the pixel above the current - pixel; -- for all other pixels, the reference value is the average of the value of the - pixel on the left and the value of the pixel above the current pixel; -- there is one code in the bitstream that specifies the value of a pixel - directly (in 4-bit resolution); -- pixel values need to be clamped inside the range [0..255] for proper - decoding. - -The algorithm purely describes the conversion from compressed Bayer code used -in the SN9C10x chips to uncompressed Bayer. Additional steps are required to -convert this to a color image (i.e. a color interpolation algorithm). - -The following Huffman codes have been found: -0: +0 (relative to reference pixel value) -100: +4 -101: -4? -1110xxxx: set absolute value to xxxx.0000 -1101: +11 -1111: -11 -11001: +20 -110000: -20 -110001: ??? - these codes are apparently not used - -[1] The Huffman compression algorithm has been reverse-engineered and - documented by Bertrik Sikken. - - -12.

Overview -=========== -This driver supports the video streaming capabilities of the devices mounting -Winbond W9967CF and Winbond W9968CF JPEG USB Dual Mode Camera Chips. OV681 -based cameras should be supported as well. - -The driver is divided into two modules: the basic one, "w9968cf", is needed for -the supported devices to work; the second one, "w9968cf-vpp", is an optional -module, which provides some useful video post-processing functions like video -decoding, up-scaling and colour conversions. - -Note that the official kernels do neither include nor support the second -module for performance purposes. Therefore, it is always recommended to -download and install the latest and complete release of the driver, -replacing the existing one, if present. - -The latest and full-featured version of the W996[87]CF driver can be found at: -http://www.linux-projects.org. Please refer to the documentation included in -that package, if you are going to use it. - -Up to 32 cameras can be handled at the same time. They can be connected and -disconnected from the host many times without turning off the computer, if -your system supports the hotplug facility. - -To change the default settings for each camera, many parameters can be passed -through command line when the module is loaded into memory. - -The driver relies on the Video4Linux, USB and I2C core modules. It has been -designed to run properly on SMP systems as well. An additional module, -"ovcamchip", is mandatory; it provides support for some OmniVision image -sensors connected to the W996[87]CF chips; if found in the system, the module -will be automatically loaded by default (provided that the kernel has been -compiled with the automatic module loading option). - - -5. Supported devices -==================== -At the moment, known W996[87]CF and OV681 based devices are: -- Aroma Digi Pen VGA Dual Mode ADG-5000 (unknown image sensor) -- AVerMedia AVerTV USB (SAA7111A, Philips FI1216Mk2 tuner, PT2313L audio chip) -- Creative Labs Video Blaster WebCam Go (OmniVision OV7610 sensor) -- Creative Labs Video Blaster WebCam Go Plus (OmniVision OV7620 sensor) -- Lebon LDC-035A (unknown image sensor) -- Ezonics EZ-802 EZMega Cam (OmniVision OV8610C sensor) -- OmniVision OV8610-EDE (OmniVision OV8610 sensor) -- OPCOM Digi Pen VGA Dual Mode Pen Camera (unknown image sensor) -- Pretec Digi Pen-II (OmniVision OV7620 sensor) -- Pretec DigiPen-480 (OmniVision OV8610 sensor) - -If you know any other W996[87]CF or OV681 based cameras, please contact me. - -The list above does not imply that all those devices work with this driver: up -until now only webcams that have an image sensor supported by the "ovcamchip" -module work. Kernel messages will always tell you whether this is case. - -Possible external microcontrollers of those webcams are not supported: this -means that still images cannot be downloaded from the device memory. - -Furthermore, it's worth to note that I was only able to run tests on my -"Creative Labs Video Blaster WebCam Go". Donations of other models, for -additional testing and full support, would be much appreciated. - - -6. Module dependencies -====================== -For it to work properly, the driver needs kernel support for Video4Linux, USB -and I2C, and the "ovcamchip" module for the image sensor. Make sure you are not -actually using any external "ovcamchip" module, given that the W996[87]CF -driver depends on the version of the module present in the official kernels. - -The following options of the kernel configuration file must be enabled and -corresponding modules must be compiled: - - # Multimedia devices - # - CONFIG_VIDEO_DEV=m - - # I2C support - # - CONFIG_I2C=m - -The I2C core module can be compiled statically in the kernel as well. - - # OmniVision Camera Chip support - # - CONFIG_VIDEO_OVCAMCHIP=m - - # USB support - # - CONFIG_USB=m - -In addition, depending on the hardware being used, only one of the modules -below is necessary: - - # USB Host Controller Drivers - # - CONFIG_USB_EHCI_HCD=m - CONFIG_USB_UHCI_HCD=m - CONFIG_USB_OHCI_HCD=m - -And finally: - - # USB Multimedia devices - # - CONFIG_USB_W9968CF=m - - -7. Module loading -================= -To use the driver, it is necessary to load the "w9968cf" module into memory -after every other module required. - -Loading can be done this way, from root: - - [root@localhost home]# modprobe usbcore - [root@localhost home]# modprobe i2c-core - [root@localhost home]# modprobe videodev - [root@localhost home]# modprobe w9968cf - -At this point the pertinent devices should be recognized: "dmesg" can be used -to analyze kernel messages: - - [user@localhost home]$ dmesg - -There are a lot of parameters the module can use to change the default -settings for each device. To list every possible parameter with a brief -explanation about them and which syntax to use, it is recommended to run the -"modinfo" command: - - [root@locahost home]# modinfo w9968cf - - -8.

Overview and features -======================== -This driver supports the video interface of the devices mounting the ZC0301 or -ZC0301P Image Processors and Control Chips. - -The driver relies on the Video4Linux2 and USB core modules. It has been -designed to run properly on SMP systems as well. - -The latest version of the ZC0301[P] driver can be found at the following URL: -http://www.linux-projects.org/ - -Some of the features of the driver are: - -- full compliance with the Video4Linux2 API (see also "Notes for V4L2 - application developers" paragraph); -- available mmap or read/poll methods for video streaming through isochronous - data transfers; -- automatic detection of image sensor; -- video format is standard JPEG; -- dynamic driver control thanks to various module parameters (see "Module - parameters" paragraph); -- up to 64 cameras can be handled at the same time; they can be connected and - disconnected from the host many times without turning off the computer, if - the system supports hotplugging; - - -5. Module dependencies -====================== -For it to work properly, the driver needs kernel support for Video4Linux and -USB. - -The following options of the kernel configuration file must be enabled and -corresponding modules must be compiled: - - # Multimedia devices - # - CONFIG_VIDEO_DEV=m - - # USB support - # - CONFIG_USB=m - -In addition, depending on the hardware being used, the modules below are -necessary: - - # USB Host Controller Drivers - # - CONFIG_USB_EHCI_HCD=m - CONFIG_USB_UHCI_HCD=m - CONFIG_USB_OHCI_HCD=m - -The ZC0301 controller also provides a built-in microphone interface. It is -supported by the USB Audio driver thanks to the ALSA API: - - # Sound - # - CONFIG_SOUND=y - - # Advanced Linux Sound Architecture - # - CONFIG_SND=m - - # USB devices - # - CONFIG_SND_USB_AUDIO=m - -And finally: - - # V4L USB devices - # - CONFIG_USB_ZC0301=m - - -6. Module loading -================= -To use the driver, it is necessary to load the "zc0301" module into memory -after every other module required: "videodev", "usbcore" and, depending on -the USB host controller you have, "ehci-hcd", "uhci-hcd" or "ohci-hcd". - -Loading can be done as shown below: - - [root@localhost home]# modprobe zc0301 - -At this point the devices should be recognized. You can invoke "dmesg" to -analyze kernel messages and verify that the loading process has gone well: - - [user@localhost home]$ dmesg - - -7. Module parameters -==================== -Module parameters are listed below: -------------------------------------------------------------------------------- -Name: video_nr -Type: short array (min = 0, max = 64) -Syntax: <-1|n[,...]> -Description: Specify V4L2 minor mode number: - -1 = use next available - n = use minor number n - You can specify up to 64 cameras this way. - For example: - video_nr=-1,2,-1 would assign minor number 2 to the second - registered camera and use auto for the first one and for every - other camera. -Default: -1 -------------------------------------------------------------------------------- -Name: force_munmap -Type: bool array (min = 0, max = 64) -Syntax: <0|1[,...]> -Description: Force the application to unmap previously mapped buffer memory - before calling any VIDIOC_S_CROP or VIDIOC_S_FMT ioctl's. Not - all the applications support this feature. This parameter is - specific for each detected camera. - 0 = do not force memory unmapping - 1 = force memory unmapping (save memory) -Default: 0 -------------------------------------------------------------------------------- -Name: frame_timeout -Type: uint array (min = 0, max = 64) -Syntax: -Description: Timeout for a video frame in seconds. This parameter is - specific for each detected camera. This parameter can be - changed at runtime thanks to the /sys filesystem interface. -Default: 2 -------------------------------------------------------------------------------- -Name: debug -Type: ushort -Syntax: -Description: Debugging information level, from 0 to 3: - 0 = none (use carefully) - 1 = critical errors - 2 = significant informations - 3 = more verbose messages - Level 3 is useful for testing only, when only one device - is used at the same time. It also shows some more informations - about the hardware being detected. This module parameter can be - changed at runtime thanks to the /sys filesystem interface. -Default: 2 -------------------------------------------------------------------------------- - - -8. Supported devices -==================== -None of the names of the companies as well as their products will be mentioned -here. They have never collaborated with the author, so no advertising. - -From the point of view of a driver, what unambiguously identify a device are -its vendor and product USB identifiers. Below is a list of known identifiers of -devices mounting the ZC0301 Image Processor and Control Chips: - -Vendor ID Product ID ---------- ---------- -0x041e 0x4017 -0x041e 0x401c -0x041e 0x401e -0x041e 0x401f -0x041e 0x4022 -0x041e 0x4034 -0x041e 0x4035 -0x041e 0x4036 -0x041e 0x403a -0x0458 0x7007 -0x0458 0x700C -0x0458 0x700f -0x046d 0x08ae -0x055f 0xd003 -0x055f 0xd004 -0x046d 0x08ae -0x0ac8 0x0301 -0x0ac8 0x301b -0x0ac8 0x303b -0x10fd 0x0128 -0x10fd 0x8050 -0x10fd 0x804e - -The list above does not imply that all those devices work with this driver: up -until now only the ones that mount the following image sensors are supported; -kernel messages will always tell you whether this is the case: - -Model Manufacturer ------ ------------ -PAS202BCB PixArt Imaging, Inc. -PB-0330 Photobit Corporation - - -9. Notes for V4L2 application developers -======================================== -This driver follows the V4L2 API specifications. In particular, it enforces two -rules: - -- exactly one I/O method, either "mmap" or "read", is associated with each -file descriptor. Once it is selected, the application must close and reopen the -device to switch to the other I/O method; - -- although it is not mandatory, previously mapped buffer memory should always -be unmapped before calling any "VIDIOC_S_CROP" or "VIDIOC_S_FMT" ioctl's. -The same number of buffers as before will be allocated again to match the size -of the new video frames, so you have to map the buffers again before any I/O -attempts on them. - - -10. Contact information -======================= -The author may be contacted by e-mail at . - -GPG/PGP encrypted e-mail's are accepted. The GPG key ID of the author is -'FCE635A4'; the public 1024-bit key should be available at any keyserver; -the fingerprint is: '88E8 F32F 7244 68BA 3958 5D40 99DA 5D2A FCE6 35A4'. - - -11.

Maybe this should be more adaptive some day... - * - * Revision 1.35 2000/09/20 10:36:08 johana - * Typo in get_lsr_info() - * - * Revision 1.34 2000/09/20 10:29:59 johana - * Let rs_chars_in_buffer() check fifo content as well. - * get_lsr_info() might work now (not tested). - * Easier to change the port to debug. - * - * Revision 1.33 2000/09/13 07:52:11 torbjore - * Support RS485 - * - * Revision 1.32 2000/08/31 14:45:37 bjornw - * After sending a break we need to reset the transmit DMA channel - * - * Revision 1.31 2000/06/21 12:13:29 johana - * Fixed wait for all chars sent when closing port. - * (Used to always take 1 second!) - * Added shadows for directions of status/ctrl signals. - * - * Revision 1.30 2000/05/29 16:27:55 bjornw - * Simulator ifdef moved a bit - * - * Revision 1.29 2000/05/09 09:40:30 mattias - * * Added description of dma registers used in timeout_interrupt - * * Removed old code - * - * Revision 1.28 2000/05/08 16:38:58 mattias - * * Bugfix for flushing fifo in timeout_interrupt - * Problem occurs when bluetooth stack waits for a small number of bytes - * containing an event acknowledging free buffers in bluetooth HW - * As before, data was stuck in fifo until more data came on uart and - * flushed it up to the stack. - * - * Revision 1.27 2000/05/02 09:52:28 jonasd - * Added fix for peculiar etrax behaviour when eop is forced on an empty - * fifo. This is used when flashing the IRMA chip. Disabled by default. - * - * Revision 1.26 2000/03/29 15:32:02 bjornw - * 2.0.34 updates - * - * Revision 1.25 2000/02/16 16:59:36 bjornw - * * Receive DMA directly into the flip-buffer, eliminating an intermediary - * receive buffer and a memcpy. Will avoid some overruns. - * * Error message on debug port if an overrun or flip buffer overrun occurs. - * * Just use the first byte in the flag flip buffer for errors. - * * Check for timeout on the serial ports only each 5/100 s, not 1/100. - * - * Revision 1.24 2000/02/09 18:02:28 bjornw - * * Clear serial errors (overrun, framing, parity) correctly. Before, the - * receiver would get stuck if an error occurred and we did not restart - * the input DMA. - * * Cosmetics (indentation, some code made into inlines) - * * Some more debug options - * * Actually shut down the serial port (DMA irq, DMA reset, receiver stop) - * when the last open is closed. Corresponding fixes in startup(). - * * rs_close() "tx FIFO wait" code moved into right place, bug & -> && fixed - * and make a special case out of port 1 (R_DMA_CHx_STATUS is broken for that) - * * e100_disable_rx/enable_rx just disables/enables the receiver, not RTS - * - * Revision 1.23 2000/01/24 17:46:19 johana - * Wait for flush of DMA/FIFO when closing port. - * - * Revision 1.22 2000/01/20 18:10:23 johana - * Added TIOCMGET ioctl to return modem status. - * Implemented modem status/control that works with the extra signals - * (DTR, DSR, RI,CD) as well. - * 3 different modes supported: - * ser0 on PB (Bundy), ser1 on PB (Lisa) and ser2 on PA (Bundy) - * Fixed DEF_TX value that caused the serial transmitter pin (txd) to go to 0 when - * closing the last filehandle, NASTY!. - * Added break generation, not tested though! - * Use SA_SHIRQ when request_irq() for ser2 and ser3 (shared with) par0 and par1. - * You can't use them at the same time (yet..), but you can hopefully switch - * between ser2/par0, ser3/par1 with the same kernel config. - * Replaced some magic constants with defines - * - * - */ - -static char *serial_version = "$Revision: 1.20 $"; - -#include -#include - -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include - -#include -#include -#include -#include -#include -#include - -#include - -/* non-arch dependent serial structures are in linux/serial.h */ -#include -/* while we keep our own stuff (struct e100_serial) in a local .h file */ -#include "serial.h" -#include - -#ifdef CONFIG_ETRAX_SERIAL_FAST_TIMER -#ifndef CONFIG_ETRAX_FAST_TIMER -#error "Enable FAST_TIMER to use SERIAL_FAST_TIMER" -#endif -#endif - -#if defined(CONFIG_ETRAX_SERIAL_RX_TIMEOUT_TICKS) && \ - (CONFIG_ETRAX_SERIAL_RX_TIMEOUT_TICKS == 0) -#error "RX_TIMEOUT_TICKS == 0 not allowed, use 1" -#endif - -#if defined(CONFIG_ETRAX_RS485_ON_PA) && defined(CONFIG_ETRAX_RS485_ON_PORT_G) -#error "Disable either CONFIG_ETRAX_RS485_ON_PA or CONFIG_ETRAX_RS485_ON_PORT_G" -#endif - -/* - * All of the compatibilty code so we can compile serial.c against - * older kernels is hidden in serial_compat.h - */ -#if defined(LOCAL_HEADERS) -#include "serial_compat.h" -#endif - -#define _INLINE_ inline - -struct tty_driver *serial_driver; - -/* serial subtype definitions */ -#ifndef SERIAL_TYPE_NORMAL -#define SERIAL_TYPE_NORMAL 1 -#endif - -/* number of characters left in xmit buffer before we ask for more */ -#define WAKEUP_CHARS 256 - -//#define SERIAL_DEBUG_INTR -//#define SERIAL_DEBUG_OPEN -//#define SERIAL_DEBUG_FLOW -//#define SERIAL_DEBUG_DATA -//#define SERIAL_DEBUG_THROTTLE -//#define SERIAL_DEBUG_IO /* Debug for Extra control and status pins */ -//#define SERIAL_DEBUG_LINE 0 /* What serport we want to debug */ - -/* Enable this to use serial interrupts to handle when you - expect the first received event on the serial port to - be an error, break or similar.

Turned and into function pointers. - v1.31 - 19990212 Zoltán Böszörményi - Major rewrite of cyrix_arr_init(): do not touch ARRs, - leave them as the BIOS have set them up. - Enable usage of all 8 ARRs. - Avoid multiplications by 3 everywhere and other - code clean ups/speed ups. - 19990213 Zoltán Böszörményi - Set up other Cyrix processors identical to the boot cpu. - Since Cyrix don't support Intel APIC, this is l'art pour l'art. - Weigh ARRs by size: - If size <= 32M is given, set up ARR# we were given. - If size > 32M is given, set up ARR7 only if it is free, - fail otherwise. - 19990214 Zoltán Böszörményi - Also check for size >= 256K if we are to set up ARR7, - mtrr_add() returns the value it gets from set_mtrr() - 19990218 Zoltán Böszörményi - Remove Cyrix "coma bug" workaround from here. - Moved to linux/arch/i386/kernel/setup.c and - linux/include/asm-i386/bugs.h - 19990228 Richard Gooch - Added MTRRIOC_KILL_ENTRY ioctl(2) - Trap for counter underflow in . - Trap for 4 MiB aligned regions for PPro, stepping <= 7. - 19990301 Richard Gooch - Created hook. - 19990305 Richard Gooch - Temporarily disable AMD support now MTRR capability flag is set. - v1.32 - 19990308 Zoltán Böszörményi - Adjust my changes (19990212-19990218) to Richard Gooch's - latest changes. (19990228-19990305) - v1.33 - 19990309 Richard Gooch - Fixed typo in message. - 19990310 Richard Gooch - Support K6-II/III based on Alan Cox's patches. - v1.34 - 19990511 Bart Hartgers - Support Centaur C6 MCR's. - 19990512 Richard Gooch - Minor cleanups. - v1.35 - 19990707 Zoltán Böszörményi - Check whether ARR3 is protected in cyrix_get_free_region() - and mtrr_del(). The code won't attempt to delete or change it - from now on if the BIOS protected ARR3. It silently skips ARR3 - in cyrix_get_free_region() or returns with an error code from - mtrr_del(). - 19990711 Zoltán Böszörményi - Reset some bits in the CCRs in cyrix_arr_init() to disable SMM - if ARR3 isn't protected. This is needed because if SMM is active - and ARR3 isn't protected then deleting and setting ARR3 again - may lock up the processor. With SMM entirely disabled, it does - not happen. - 19990812 Zoltán Böszörményi - Rearrange switch() statements so the driver accomodates to - the fact that the AMD Athlon handles its MTRRs the same way - as Intel does. - 19990814 Zoltán Böszörményi - Double check for Intel in mtrr_add()'s big switch() because - that revision check is only valid for Intel CPUs. - 19990819 Alan Cox - Tested Zoltan's changes on a pre production Athlon - 100% - success. - 19991008 Manfred Spraul - replaced spin_lock_reschedule() with a normal semaphore. - v1.36 - 20000221 Richard Gooch - Compile fix if procfs and devfs not enabled. - Formatting changes. - v1.37 - 20001109 H. Peter Anvin - Use the new centralized CPU feature detects. - - v1.38 - 20010309 Dave Jones - Add support for Cyrix III. - - v1.39 - 20010312 Dave Jones - Ugh, I broke AMD support. - Reworked fix by Troels Walsted Hansen - - v1.40 - 20010327 Dave Jones - Adapted Cyrix III support to include VIA C3. - - v2.0 - 20020306 Patrick Mochel - Split mtrr.c -> mtrr/*.c - Converted to Linux Kernel Coding Style - Fixed several minor nits in form - Moved some SMP-only functions out, so they can be used - for power management in the future. - TODO: Fix user interface cruft. diff --git a/arch/i386/kernel/cpu/mtrr/main-xen.c b/arch/i386/kernel/cpu/mtrr/main-xen.c deleted file mode 100644 index 4c65427f0..000000000 --- a/arch/i386/kernel/cpu/mtrr/main-xen.c +++ /dev/null @@ -1,197 +0,0 @@ -#include -#include -#include -#include -#include -#include -#include - -#include -#include "mtrr.h" - -static DEFINE_MUTEX(mtrr_mutex);
