When applied to revision control, this means doing away with -client-server, and changing to a parent-child model... essentially -peer-to-peer. On the developer's end, this also represents a -fundamental disruption in the standard workflow of changes, commits, -and merges. You will need to take a few minutes to think about -how to best work under BitKeeper, and re-optimize things a bit. -In some sense it is a bit radical, because it might described as -tossing changes out into a maelstrom and having them magically -land at the right destination... but I'm getting ahead of myself. - -Let's start with this progression: -Each BitKeeper source tree on disk is a repository unto itself. -Each repository has a parent (except the root/original, of course). -Each repository contains a set of a changesets ("csets"). -Each cset is one or more changed files, bundled together. - -Each tree is a repository, so all changes are checked into the local -tree. 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. This requires BK 3.x, though. - - bk export -tpatch -r`bk repogca bk://linux.bkbits.net/linux-2.5`,+ - diff --git a/Documentation/BK-usage/bk-make-sum b/Documentation/BK-usage/bk-make-sum deleted file mode 100755 index 58ca46a0f..000000000 --- a/Documentation/BK-usage/bk-make-sum +++ /dev/null @@ -1,34 +0,0 @@ -#!/bin/sh -e -# DIR=$HOME/BK/axp-2.5 -# cd $DIR - -LINUS_REPO=$1 -DIRBASE=`basename $PWD` - -{ -cat </dev/null - -cat < (:D: :I:)\n$each(:C:){ (:C:)\n}\n}' - - -} > /tmp/linus.txt - -cat < 13/02/2002 -# -# Add diffstat output after Changelog 21/02/2002 - -PROG=bksend - -usage() { - echo "usage: $PROG -r" - echo -e "\twhere is of the form '1.23', '1.23..', '1.23..1.27'," - echo -e "\tor '+' to indicate the most recent revision" - - exit 1 -} - -case $1 in --r) REV=$2; shift ;; --r*) REV=`echo $1 | sed 's/^-r//'` ;; -*) echo "$PROG: no revision given, you probably don't want that";; -esac - -[ -z "$REV" ] && usage - -echo "You can import this changeset into BK by piping this whole message to:" -echo "'| bk receive [path to repository]' or apply the patch as usual." - -SEP="\n===================================================================\n\n" -echo -e $SEP -bk changes -r$REV -echo -bk export -tpatch -du -h -r$REV | diffstat -echo; echo -bk export -tpatch -du -h -r$REV -echo -e $SEP -bk send -wgzip_uu -r$REV - diff --git a/Documentation/BK-usage/bz64wrap b/Documentation/BK-usage/bz64wrap deleted file mode 100755 index be7808768..000000000 --- a/Documentation/BK-usage/bz64wrap +++ /dev/null @@ -1,41 +0,0 @@ -#!/bin/sh - -# bz64wrap - the sending side of a bzip2 | base64 stream -# Andreas Dilger Jan 2002 - - -PATH=$PATH:/usr/bin:/usr/local/bin:/usr/freeware/bin - -# A program to generate base64 encoding on stdout -BASE64_ENCODE="uuencode -m /dev/stdout" -BASE64_BEGIN= -BASE64_END= - -BZIP=NO -BASE64=NO - -# Test if we have the bzip program installed -bzip2 -c /dev/null > /dev/null 2>&1 && BZIP=YES - -# Test if uuencode can handle the -m (MIME) encoding option -$BASE64_ENCODE < /dev/null > /dev/null 2>&1 && BASE64=YES - -if [ $BASE64 = NO ]; then - BASE64_ENCODE=mimencode - BASE64_BEGIN="begin-base64 644 -" - BASE64_END="====" - - $BASE64_ENCODE < /dev/null > /dev/null 2>&1 && BASE64=YES -fi - -if [ $BZIP = NO -o $BASE64 = NO ]; then - echo "$0: can't use bz64 encoding: bzip2=$BZIP, $BASE64_ENCODE=$BASE64" - exit 1 -fi - -# Sadly, mimencode does not appear to have good "begin" and "end" markers -# like uuencode does, and it is picky about getting the right start/end of -# the base64 stream, so we handle this internally. -echo "$BASE64_BEGIN" -bzip2 -9 | $BASE64_ENCODE -echo "$BASE64_END" diff --git a/Documentation/BK-usage/cpcset b/Documentation/BK-usage/cpcset deleted file mode 100755 index b8faca97d..000000000 --- a/Documentation/BK-usage/cpcset +++ /dev/null @@ -1,36 +0,0 @@ -#!/bin/sh -# -# Purpose: Copy changeset patch and description from one -# repository to another, unrelated one. -# -# usage: cpcset [revision] [from-repository] [to-repository] -# - -REV=$1 -FROM=$2 -TO=$3 -TMPF=/tmp/cpcset.$$ - -rm -f $TMPF* - -CWD_SAVE=`pwd` -cd $FROM -bk changes -r$REV | \ - grep -v '^ChangeSet' | \ - sed -e 's/^ //g' > $TMPF.log - -USERHOST=`bk changes -r$REV | grep '^ChangeSet' | awk '{print $4}'` -export BK_USER=`echo $USERHOST | awk '-F@' '{print $1}'` -export BK_HOST=`echo $USERHOST | awk '-F@' '{print $2}'` - -bk export -tpatch -hdu -r$REV > $TMPF.patch && \ -cd $CWD_SAVE && \ -cd $TO && \ -bk import -tpatch -CFR -y"`cat $TMPF.log`" $TMPF.patch . && \ -bk commit -y"`cat $TMPF.log`" - -rm -f $TMPF* - -echo changeset $REV copied. -echo "" - diff --git a/Documentation/BK-usage/cset-to-linus b/Documentation/BK-usage/cset-to-linus deleted file mode 100755 index d28a96f8c..000000000 --- a/Documentation/BK-usage/cset-to-linus +++ /dev/null @@ -1,49 +0,0 @@ -#!/usr/bin/perl -w - -use strict; - -my ($lhs, $rev, $tmp, $rhs, $s); -my @cset_text = (); -my @pipe_text = (); -my $have_cset = 0; - -while (<>) { - next if /^---/; - - if (($lhs, $tmp, $rhs) = (/^(ChangeSet\@)([^,]+)(, .*)$/)) { - &cset_rev if ($have_cset); - - $rev = $tmp; - $have_cset = 1; - - push(@cset_text, $_); - } - - elsif ($have_cset) { - push(@cset_text, $_); - } -} -&cset_rev if ($have_cset); -exit(0); - - -sub cset_rev { - my $empty_cset = 0; - - open PIPE, "bk export -tpatch -hdu -r $rev | diffstat -p1 2>/dev/null |" or die; - while ($s = ) { - $empty_cset = 1 if ($s =~ /0 files changed/); - push(@pipe_text, $s); - } - close(PIPE); - - if (!

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. Be sure - to test it thoroughly. - - - - diff --git a/Documentation/DocBook/scsidrivers.tmpl b/Documentation/DocBook/scsidrivers.tmpl deleted file mode 100644 index d058e65da..000000000 --- a/Documentation/DocBook/scsidrivers.tmpl +++ /dev/null @@ -1,193 +0,0 @@ - - - - - - SCSI Subsystem Interfaces - - - - Douglas - Gilbert - -

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 .

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.

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.

Only functions whose implementation is likely to -differ across board designs are required at this level. Some examples -include: - - - configuring card detect lines to generate interrupts - - sensing the legal voltage levels for inserted cards - - asserting the reset signal for a card - -Functions which are assumed to be the same across all designs are -performed within the generic socket driver itself. Some examples of these -kinds of operations include: - - - configuring memory access times based on the core clock frequency - - reads/writes on memory, byte swizzling, ... - -The current implementation allows the specific per-board set of low-level -operations to be determined at run time.

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/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).

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.

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 -

They are included in this release. - -Stable Release -2.2.0 Feb 01 2001 - o Bug fix in wancfg GUI configurator. - The edit function didn't work properly. - - -bata1-2.2.1 Feb 09 2001 - o WANPIPE TTY Driver emulation. - Two modes of operation Sync and Async. - Sync: Using the PPPD daemon, kernel SyncPPP layer - and the Wanpipe sync TTY driver: a PPP protocol - connection can be established via Sangoma adapter, over - a T1 leased line. - - The 2.4.0 kernel PPP layer supports MULTILINK - protocol, that can be used to bundle any number of Sangoma - adapters (T1 lines) into one, under a single IP address. - Thus, efficiently obtaining multiple T1 throughput. - - NOTE: The remote side must also implement MULTILINK PPP - protocol. - - Async:Using the PPPD daemon, kernel AsyncPPP layer - and the WANPIPE async TTY driver: a PPP protocol - connection can be established via Sangoma adapter and - a modem, over a telephone line. - - Thus, the WANPIPE async TTY driver simulates a serial - TTY driver that would normally be used to interface the - MODEM to the linux kernel. - - o WANPIPE PPP Backup Utility - This utility will monitor the state of the PPP T1 line. - In case of failure, a dial up connection will be established - via pppd daemon, ether via a serial tty driver (serial port), - or a WANPIPE async TTY driver (in case serial port is unavailable). - - Furthermore, while in dial up mode, the primary PPP T1 link - will be monitored for signs of life. - - If the PPP T1 link comes back to life, the dial up connection - will be shutdown and T1 line re-established. - - - o New Setup installation script. - Option to UPGRADE device drivers if the kernel source has - already been patched with WANPIPE. - - Option to COMPILE WANPIPE modules against the currently - running kernel, thus no need for manual kernel and module - re-compilatin. - - o Updates and Bug Fixes to wancfg utility. - -bata2-2.2.1 Feb 20 2001 - - o Bug fixes to the CHDLC device drivers. - The driver had compilation problems under kernels - 2.2.14 or lower. - - o Bug fixes to the Setup installation script. - The device drivers compilation options didn't work - properly. - - o Update to the wpbackupd daemon. - Optimized the cross-over times, between the primary - link and the backup dialup. - -beta3-2.2.1 Mar 02 2001 - o Patches for 2.4.2 kernel. - - o Bug fixes to util/ make files. - o Bug fixes to the Setup installation script. - - o Took out the backupd support and made it into - as separate package. - -beta4-2.2.1 Mar 12 2001 - - o Fix to the Frame Relay Device driver. - IPSAC sends a packet of zero length - header to the frame relay driver. The - driver tries to push its own 2 byte header - into the packet, which causes the driver to - crash. - - o Fix the WANPIPE re-configuration code. - Bug was found by trying to run the cfgft1 while the - interface was already running. - - o Updates to cfgft1. - Writes a wanpipe#.cfgft1 configuration file - once the CSU/DSU is configured. This file can - holds the current CSU/DSU configuration. - - - ->>>>>> END OF README <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< - - diff --git a/Documentation/scsi/ChangeLog b/Documentation/scsi/ChangeLog deleted file mode 100644 index dc88ee2ab..000000000 --- a/Documentation/scsi/ChangeLog +++ /dev/null @@ -1,2023 +0,0 @@ -Sat Jan 18 15:51:45 1997 Richard Henderson - - * Don't play with usage_count directly, instead hand around - the module header and use the module macros. - -Fri May 17 00:00:00 1996 Leonard N.

See http://www.xirlink.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.

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 .

It contains -a lot of extra information, a FAQ, and the binary plugin 'PWCX'. This plugin -contains decompression routines that allow you to use higher image sizes and -framerates; in addition the webcam uses less bandwidth on the USB bus (handy -if you want to run more than 1 camera simultaneously). 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.

Overview and features -======================== -This driver attempts to support the video and audio streaming capabilities 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 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 - your 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 - - # 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_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: int 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: debug -Type: int -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. -Default: 2 -------------------------------------------------------------------------------- - - -8. Optional device control through "sysfs" [1] -========================================== -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 12-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 0x00 or 0x01 Unknown meaning. The exact value depends on the chip. -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. - -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] 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. 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 SN9C10x PC camera controllers: - -Vendor ID Product ID ---------- ---------- -0x0c45 0x6001 -0x0c45 0x6005 -0x0c45 0x6009 -0x0c45 0x600d -0x0c45 0x6024 -0x0c45 0x6025 -0x0c45 0x6028 -0x0c45 0x6029 -0x0c45 0x602a -0x0c45 0x602b -0x0c45 0x602c -0x0c45 0x6030 -0x0c45 0x6080 -0x0c45 0x6082 -0x0c45 0x6083 -0x0c45 0x6088 -0x0c45 0x608a -0x0c45 0x608b -0x0c45 0x608c -0x0c45 0x608e -0x0c45 0x608f -0x0c45 0x60a0 -0x0c45 0x60a2 -0x0c45 0x60a3 -0x0c45 0x60a8 -0x0c45 0x60aa -0x0c45 0x60ab -0x0c45 0x60ac -0x0c45 0x60ae -0x0c45 0x60af -0x0c45 0x60b0 -0x0c45 0x60b2 -0x0c45 0x60b3 -0x0c45 0x60b8 -0x0c45 0x60ba -0x0c45 0x60bb -0x0c45 0x60bc -0x0c45 0x60be - -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 ------ ------------ -HV7131D Hynix Semiconductor, Inc. -MI-0343 Micron Technology, Inc. -PAS106B PixArt Imaging, Inc. -PAS202BCB PixArt Imaging, Inc. -TAS5110C1B Taiwan Advanced Sensor Corporation -TAS5130D1B Taiwan Advanced Sensor Corporation - -All the available control settings of each image sensor are supported through -the V4L2 interface. - -Donations of new models for further testing and support would be much -appreciated. Non-available hardware will not be supported by the author of this -driver. - - -10. How to add plug-in's for new image sensors -============================================== -It should be easy to write plug-in's for new sensors by using the small API -that has been created for this purpose, which is present in "sn9c102_sensor.h" -(documentation is included there). As an example, have a look at the code in -"sn9c102_pas106b.c", which uses the mentioned interface. - -At the moment, possible unsupported image sensors are: CIS-VF10 (VGA), -OV7620 (VGA), OV7630 (VGA). - - -11. 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). - - -12. 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. - - -13.

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. Once the driver is installed, -every time an application tries to open a recognized device, "w9968cf" checks -the presence of the "w9968cf-vpp" module and loads it automatically by default. - -Please keep in mind that official kernels do not include the second module for -performance purposes. However it is always recommended to download and install -the latest and complete release of the driver, replacing the existing one, if -present: it will be still even possible not to load the "w9968cf-vpp" module at -all, if you ever want to. Another important missing feature of the version in -the official Linux 2.4 kernels is the writeable /proc filesystem interface. - -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.

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.

Martin Mares - * - * Feb 6, 1998 : No longer using BIOS to find devices and device classes. [mj] - * - * May 1, 1998 : Support for peer host bridges. [mj] - * - * Jun 19, 1998 : Changed to use spinlocks, so that PCI configuration space - * can be accessed from interrupts even on SMP systems. [mj] - * - * August 1998 : Better support for peer host bridges and more paranoid - * checks for direct hardware access. Ugh, this file starts to look as - * a large gallery of common hardware bug workarounds (watch the comments) - * -- the PCI specs themselves are sane, but most implementors should be - * hit hard with \hammer scaled \magstep5. [mj] - * - * Jan 23, 1999 : More improvements to peer host bridge logic. i450NX fixup. [mj] - * - * Feb 8, 1999 : Added UM8886BF I/O address fixup. [mj] - * - * August 1999 : New resource management and configuration access stuff. [mj] - * - * Sep 19, 1999 : Use PCI IRQ routing tables for detection of peer host bridges. - * Based on ideas by Chris Frantz and David Hinds. [mj] - * - * Sep 28, 1999 : Handle unreported/unassigned IRQs. Thanks to Shuu Yamaguchi - * for a lot of patience during testing. [mj] - * - * Oct 8, 1999 : Split to pci-i386.c, pci-pc.c and pci-visws.c.

Distance pointers never point before the beginning of the output - stream. - 2. Distance pointers can point back across blocks, up to 32k away. - 3. There is an implied maximum of 7 bits for the bit length table and - 15 bits for the actual data. - 4. If only one code exists, then it is encoded using one bit. (Zero - would be more efficient, but perhaps a little confusing.) If two - codes exist, they are coded using one bit each (0 and 1). - 5. There is no way of sending zero distance codes--a dummy must be - sent if there are none. (History: a pre 2.0 version of PKZIP would - store blocks with no distance codes, but this was discovered to be - too harsh a criterion.) Valid only for 1.93a. 2.04c does allow - zero distance codes, which is sent as one code of zero bits in - length. - 6. There are up to 286 literal/length codes. Code 256 represents the - end-of-block. Note however that the static length tree defines - 288 codes just to fill out the Huffman codes. Codes 286 and 287 - cannot be used though, since there is no length base or extra bits - defined for them. Similarily, there are up to 30 distance codes. - However, static trees define 32 codes (all 5 bits) to fill out the - Huffman codes, but the last two had better not show up in the data. - 7. Unzip can check dynamic Huffman blocks for complete code sets. - The exception is that a single code would not be complete (see #4). - 8. The five bits following the block type is really the number of - literal codes sent minus 257. - 9. Length codes 8,16,16 are interpreted as 13 length codes of 8 bits - (1+6+6). Therefore, to output three times the length, you output - three codes (1+1+1), whereas to output four times the same length, - you only need two codes (1+3). Hmm. - 10. In the tree reconstruction algorithm, Code = Code + Increment - only if BitLength(i) is not zero. (Pretty obvious.) - 11. Correction: 4 Bits: # of Bit Length codes - 4 (4 - 19) - 12. Note: length code 284 can represent 227-258, but length code 285 - really is 258. The last length deserves its own, short code - since it gets used a lot in very redundant files. The length - 258 is special since 258 - 3 (the min match length) is 255. - 13. The literal/length and distance code bit lengths are read as a - single stream of lengths. It is possible (and advantageous) for - a repeat code (16, 17, or 18) to go across the boundary between - the two sets of lengths. - */ - - -local void inflate_blocks_reset( - inflate_blocks_statef *s, - z_stream *z, - uLongf *c -) -{ - if (s->checkfn != Z_NULL) - *c = s->check; - if (s->mode == BTREE || s->mode == DTREE) - ZFREE(z, s->sub.trees.blens, s->sub.trees.nblens * sizeof(uInt)); - if (s->mode == CODES) - { - inflate_codes_free(s->sub.decode.codes, z); - inflate_trees_free(s->sub.decode.td, z); - inflate_trees_free(s->sub.decode.tl, z); - } - s->mode = TYPE; - s->bitk = 0; - s->bitb = 0; - s->read = s->write = s->window; - if (s->checkfn != Z_NULL) - s->check = (*s->checkfn)(0L, Z_NULL, 0); - Trace((stderr, "inflate: blocks reset\n")); -} - - -local inflate_blocks_statef *inflate_blocks_new( - z_stream *z, - check_func c, - uInt w -) -{ - inflate_blocks_statef *s; - - if ((s = (inflate_blocks_statef *)ZALLOC - (z,1,sizeof(struct inflate_blocks_state))) == Z_NULL) - return s; - if ((s->window = (Bytef *)ZALLOC(z, 1, w)) == Z_NULL) - { - ZFREE(z, s, sizeof(struct inflate_blocks_state)); - return Z_NULL; - } - s->end = s->window + w; - s->checkfn = c; - s->mode = TYPE; - Trace((stderr, "inflate: blocks allocated\n")); - inflate_blocks_reset(s, z, &s->check); - return s; -} - - -local int inflate_blocks( - inflate_blocks_statef *s, - z_stream *z, - int r -) -{ - uInt t; /* temporary storage */ - uLong b; /* bit buffer */ - uInt k; /* bits in bit buffer */ - Bytef *p; /* input data pointer */ - uInt n; /* bytes available there */ - Bytef *q; /* output window write pointer */ - uInt m; /* bytes to end of window or read pointer */ - - /* copy input/output information to locals (UPDATE macro restores) */ - LOAD - - /* process input based on current state */ - while (1) switch (s->mode) - { - case TYPE: - NEEDBITS(3) - t = (uInt)b & 7; - s->last = t & 1; - switch (t >> 1) - { - case 0: /* stored */ - Trace((stderr, "inflate: stored block%s\n", - s->last ?

However, the time it takes - to build this table can also be a factor if the data being decoded - is not very long. The most common codes are necessarily the - shortest codes, so those codes dominate the decoding time, and hence - the speed. The idea is you can have a shorter table that decodes the - shorter, more probable codes, and then point to subsidiary tables for - the longer codes. The time it costs to decode the longer codes is - then traded against the time it takes to make longer tables. - - This results of this trade are in the variables lbits and dbits - below. lbits is the number of bits the first level table for literal/ - length codes can decode in one step, and dbits is the same thing for - the distance codes. Subsequent tables are also less than or equal to - those sizes. These values may be adjusted either when all of the - codes are shorter than that, in which case the longest code length in - bits is used, or when the shortest code is *longer* than the requested - table size, in which case the length of the shortest code in bits is - used. - - There are two different values for the two tables, since they code a - different number of possibilities each. The literal/length table - codes 286 possible values, or in a flat code, a little over eight - bits. The distance table codes 30 possible values, or a little less - than five bits, flat. The optimum values for speed end up being - about one bit more than those, so lbits is 8+1 and dbits is 5+1. - The optimum values may differ though from machine to machine, and - possibly even between compilers.

If you are enabling the cache, you must perform a - global invalidate. If you are disabling the cache, you must - flush the cache contents first. This routine takes care of - doing these things. When first enabling the cache, make sure - you pass in the L2CR you want, as well as passing in the - global invalidate bit set. A global invalidate will only be - performed if the L2I bit is set in applyThis. When enabling - the cache, you should also set the L2E bit in applyThis. If - you want to modify the L2CR contents after the cache has been - enabled, the recommended procedure is to first call - __setL2CR(0) to disable the cache and then call it again with - the new values for L2CR. Examples: - - _setL2CR(0) - disables the cache - _setL2CR(0xB3A04000) - enables my G3 upgrade card: - - L2E set to turn on the cache - - L2SIZ set to 1MB - - L2CLK set to 1:1 - - L2RAM set to pipelined synchronous late-write - - L2I set to perform a global invalidation - - L2OH set to 0.5 nS - - L2DF set because this upgrade card - requires it - - A similar call should work for your card. You need to know - the correct setting for your card and then place them in the - fields I have outlined above. Other fields support optional - features, such as L2DO which caches only data, or L2TS which - causes cache pushes from the L1 cache to go to the L2 cache - instead of to main memory. - -IMPORTANT: - Starting with the 7450, the bits in this register have moved - or behave differently.

Distance pointers never point before the beginning of the output - stream. - 2. Distance pointers can point back across blocks, up to 32k away. - 3. There is an implied maximum of 7 bits for the bit length table and - 15 bits for the actual data. - 4. If only one code exists, then it is encoded using one bit. (Zero - would be more efficient, but perhaps a little confusing.) If two - codes exist, they are coded using one bit each (0 and 1). - 5. There is no way of sending zero distance codes--a dummy must be - sent if there are none. (History: a pre 2.0 version of PKZIP would - store blocks with no distance codes, but this was discovered to be - too harsh a criterion.) Valid only for 1.93a. 2.04c does allow - zero distance codes, which is sent as one code of zero bits in - length. - 6. There are up to 286 literal/length codes. Code 256 represents the - end-of-block. Note however that the static length tree defines - 288 codes just to fill out the Huffman codes. Codes 286 and 287 - cannot be used though, since there is no length base or extra bits - defined for them. Similarily, there are up to 30 distance codes. - However, static trees define 32 codes (all 5 bits) to fill out the - Huffman codes, but the last two had better not show up in the data. - 7. Unzip can check dynamic Huffman blocks for complete code sets. - The exception is that a single code would not be complete (see #4). - 8. The five bits following the block type is really the number of - literal codes sent minus 257. - 9. Length codes 8,16,16 are interpreted as 13 length codes of 8 bits - (1+6+6). Therefore, to output three times the length, you output - three codes (1+1+1), whereas to output four times the same length, - you only need two codes (1+3). Hmm. - 10. In the tree reconstruction algorithm, Code = Code + Increment - only if BitLength(i) is not zero. (Pretty obvious.) - 11. Correction: 4 Bits: # of Bit Length codes - 4 (4 - 19) - 12. Note: length code 284 can represent 227-258, but length code 285 - really is 258. The last length deserves its own, short code - since it gets used a lot in very redundant files. The length - 258 is special since 258 - 3 (the min match length) is 255. - 13. The literal/length and distance code bit lengths are read as a - single stream of lengths. It is possible (and advantageous) for - a repeat code (16, 17, or 18) to go across the boundary between - the two sets of lengths. - */ - - -local void inflate_blocks_reset( - inflate_blocks_statef *s, - z_stream *z, - uLongf *c -) -{ - if (s->checkfn != Z_NULL) - *c = s->check; - if (s->mode == BTREE || s->mode == DTREE) - ZFREE(z, s->sub.trees.blens, s->sub.trees.nblens * sizeof(uInt)); - if (s->mode == CODES) - { - inflate_codes_free(s->sub.decode.codes, z); - inflate_trees_free(s->sub.decode.td, z); - inflate_trees_free(s->sub.decode.tl, z); - } - s->mode = TYPE; - s->bitk = 0; - s->bitb = 0; - s->read = s->write = s->window; - if (s->checkfn != Z_NULL) - s->check = (*s->checkfn)(0L, Z_NULL, 0); - Trace((stderr, "inflate: blocks reset\n")); -} - - -local inflate_blocks_statef *inflate_blocks_new( - z_stream *z, - check_func c, - uInt w -) -{ - inflate_blocks_statef *s; - - if ((s = (inflate_blocks_statef *)ZALLOC - (z,1,sizeof(struct inflate_blocks_state))) == Z_NULL) - return s; - if ((s->window = (Bytef *)ZALLOC(z, 1, w)) == Z_NULL) - { - ZFREE(z, s, sizeof(struct inflate_blocks_state)); - return Z_NULL; - } - s->end = s->window + w; - s->checkfn = c; - s->mode = TYPE; - Trace((stderr, "inflate: blocks allocated\n")); - inflate_blocks_reset(s, z, &s->check); - return s; -} - - -local int inflate_blocks( - inflate_blocks_statef *s, - z_stream *z, - int r -) -{ - uInt t; /* temporary storage */ - uLong b; /* bit buffer */ - uInt k; /* bits in bit buffer */ - Bytef *p; /* input data pointer */ - uInt n; /* bytes available there */ - Bytef *q; /* output window write pointer */ - uInt m; /* bytes to end of window or read pointer */ - - /* copy input/output information to locals (UPDATE macro restores) */ - LOAD - - /* process input based on current state */ - while (1) switch (s->mode) - { - case TYPE: - NEEDBITS(3) - t = (uInt)b & 7; - s->last = t & 1; - switch (t >> 1) - { - case 0: /* stored */ - Trace((stderr, "inflate: stored block%s\n", - s->last ?

However, the time it takes - to build this table can also be a factor if the data being decoded - is not very long. The most common codes are necessarily the - shortest codes, so those codes dominate the decoding time, and hence - the speed. The idea is you can have a shorter table that decodes the - shorter, more probable codes, and then point to subsidiary tables for - the longer codes. The time it costs to decode the longer codes is - then traded against the time it takes to make longer tables. - - This results of this trade are in the variables lbits and dbits - below. lbits is the number of bits the first level table for literal/ - length codes can decode in one step, and dbits is the same thing for - the distance codes. Subsequent tables are also less than or equal to - those sizes. These values may be adjusted either when all of the - codes are shorter than that, in which case the longest code length in - bits is used, or when the shortest code is *longer* than the requested - table size, in which case the length of the shortest code in bits is - used. - - There are two different values for the two tables, since they code a - different number of possibilities each. The literal/length table - codes 286 possible values, or in a flat code, a little over eight - bits. The distance table codes 30 possible values, or a little less - than five bits, flat. The optimum values for speed end up being - about one bit more than those, so lbits is 8+1 and dbits is 5+1. - The optimum values may differ though from machine to machine, and - possibly even between compilers.

I have noticed that - the Mitsumi 2x/4x drives are just less tolerant and the firmware is - not smart enough to drop speed, so let's just kludge it with software! - ****** THE 4X SPEED MITSUMI DRIVES HAVE THE SAME PROBLEM!!!!!! ****** - Anyone want to "DONATE" one to me?! ;) I hear sometimes they are - even WORSE! ;) - ** HINT... HINT... TAKE NOTES MITSUMI This could save some hassles with - certain "large" CD's that have data on the outside edge in your - DOS DRIVERS .... Accuracy counts... speed is secondary ;) - 17 June 95 Modifications By Andrew J. Kroll - 07 July 1995 Modifications by Andrew J. Kroll - - Bjorn Ekwall added unregister_blkdev to mcd_init() - - Michael K. Johnson added retries on open - for slow drives which take a while to recognize that they contain - a CD. - - November 1997 -- ported to the Uniform CD-ROM driver by Erik Andersen. - March 1999 -- made io base and irq CONFIG_ options (Tigran Aivazian). - - November 1999 -- Make kernel-parameter implementation work with 2.3.x - Removed init_module & cleanup_module in favor of - module_init & module_exit. - Torben Mathiasen - - September 2001 - Reformatted and cleaned up the code - Alan Cox -*/ - -#include - -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include - -/* #define REALLY_SLOW_IO */ -#include -#include -#include -#include -#include - -#include "mcd.h" - -/* I added A flag to drop to 1x speed if too many errors 0 = 1X ; 1 = 2X */ -static int mcdDouble; - -/* How many sectors to hold at 1x speed counter */ -static int mcd1xhold; - -/* Is the drive connected properly and responding??

See the GNU General Public License - for more details. - - You should have received a copy of the GNU General Public License along - with this program; if not write to the Free Software Foundation, Inc., - 675 Mass Ave, Cambridge, MA 02139, USA. - - -This document describes the software used with the Digi/Linux driver package. -The four user programs listed below are described in this document: - - 1. digiConfig -> Application that configures the Digi driver. - - 2. digiDload -> Application which initializes the Digi hardware. - - 3. buildPCI -> Application which provides the user a method of - building device nodes for PCI devices. - - 4. ditty -> Application which provides the user a method of - configuring terminal options on Digi hardware. - - - --------------------------------------------------------------------------- -1. Configuring driver/kernel for Digi products --------------------------------------------------------------------------- - - The Digi driver must be configured each time Digi hardware is added - or removed. There are two supported methods of doing this. The - first method configures the driver dynamically at boot time but requires - the user to utilize the lilo loader. This method is the preffered method - as it does not require the rebuilding of the kernel. In order to use lilo - to configure Digi boards at boot time an appropriate append command should - be added to /etc/lilo.conf below the appropriate label decleration. - See footer 4. The append commands format is a string of comma separated - identifiers or integers used to configure supported boards. These six - values in order are: - - Enable/Disable this card or Override, - Type of card: PC/Xe (AccelePort) (0), PC/Xeve (1), PC/Xem or PC/Xr (2), - EISA/Xem (3), PC/Xe (64K) (4), PC/Xi (5). - Enable/Disable alternate pin arrangement, - Number of ports on this card, - I/O Port where card is configured (in HEX if using string identifiers), - Base of memory window (in HEX if using string identifiers) - - A sample append command is given below which if used would configure and - enable a PC/Xe with 8 ports, at i/o address 200, memory address 0xd0000 - with alt pin turned off. The lilo.conf file should look like this: - - image = /vmlinuz - root = /dev/hda2 - label = vmlinuz - append="digiepca=E,PC/Xe,D,8,200,D0000" - - likewise the below will perform the same function: - - image = /vmlinuz - root = /dev/hda2 - label = vmlinuz - append="digiepca=1,0,0,8,512,851968" - - Note: - - PCI boards are auto-detected and configured (Hence their codes are - not given here). Do not attempt to configure PCI boards with the lilo - append command. - - If configuration data has been specified by using digiConfig (Described - below), and you wish to override this configuration using lilo without - specifying a specific card (Example if there are PCI cards in the system) - the following override command will accomplish this: - - -> append="digiepca=2" - - If lilo is not enabled, the second method of configuring Digi hardware - will have to be used. digiConfig is an application that can be used - to inform the system of any additions, deletions, or modifications - involving Digi hardware. To use this method the operator executes - digiConfig anytime an EISA or ISA card is added that he wishes to use. - This routine is also used to remove cards from the system, and to modify - parameters of those cards already present in the system. Upon being - executed digiConfig modifies files accessed by the Digi driver. To make - these changes permanent; the operating system must be recompiled. After - the operating system has been recompiled and booted, the changes made with - digiConfig will be introduced to the user. This program MUST be executed - every time Digi EISA/ISA hardware configuration changes. Note, it is not - necessary to execute digiConfig in order to configure the Digi PCI cards. - These cards are self-identifying and will be recognized by the driver. - They cannot be displayed using digiConfig nor will digiConfig build the - device nodes their device nodes. See footer 1. - - To execute digiConfig; simply type: digiConfig - - The application will query you for the type, memory address, port - address, number of ports, alt pin disposition and status of each board - that exist on the system. Note, currently this driver only supports - PC/Xe, PC/Xeve, PC/Xi, PC/Xr, and PC/Xem as well as their EISA and PCI - implementations if applicable. All supported cards (Other than PCI) that - are present should be registered via digiConfig. See footer 2. - - After all cards have been configured select exit. The system will then - inform you if any changes have been made, and ask you if it is okay to - make these changes permanent. If the data entered is correct, select okay. - Selecting cancel will prevent the changes from becoming active. digiConfig - can then be re-executed to configure the system again. - --------------------------------------------------------------------------- -2. Initializing Digi hardware with digiDload --------------------------------------------------------------------------- - - digiDload is the application executed after the Digi driver has been - loaded. It is responsible for initializing the hardware and leaving - it in a state such that the Digi board may be operated by the user. - The application may be placed anywhere on the path, but its related - support files must be located in /etc/digi. The related files are: - - sxfep.bin - sxbios.bin - xxfep.bin - xxbios.bin - - The format for this command is "digiDload [v]". If given the "v" - option turns on verbosity. If not given the application runs in quite - mode. To execute the program simply type: - - digiDload - - Upon completion digiDload will generate the below message: - - "digiDload complete: Card initialized" - - At this point the card is configured and ready for normal usage. See - technotes.doc for information on how how ports are determined and - assigned. - --------------------------------------------------------------------------- -3. Build PCI device nodes with buildPCI --------------------------------------------------------------------------- - - buildPCI is an application useful for building the necessary device nodes - for Digi PCI cards. It is reccomended that this tool be used because the - current digiConfig application does not provide this function for PCI cards - (Though it does build device nodes for non-PCI cards). To use this program - execute the following:first install the driver, and execute digiDload (See above). After digiDload - has successfully loaded, execute the following: - - buildPCI - - Where arg1 is the number of ports connected to Digi cards that are not PCI - (As shown by the digiConfig utility), and arg2 is the number of ports - connected to Digi cards that are PCI. - - Note, buildPCI only has to be ran once to build the necessary device - nodes. Though this program may be executed at anytime, we reccomend - delaying execution until the first time you install the package and after - digiDload has been executed. - --------------------------------------------------------------------------- -4. Setting Terminal Options with ditty --------------------------------------------------------------------------- - -ditty is a utility program that sets and displays the terminal options -for Digi intelligent serial products. See man ditty for detailed information. - - -Footnotes: - -1. The 1.2.x kernel does not provide a method of mapping the high - addresses (Normally higher than RAM) associated with PCI. For this - reason, this driver disables PCI support while running under the 1.2.x - kernels. - -2. PCI cards should not and cannot be registered with digiConfig. After - the driver has been loaded buildPCI may be executed to construct the - necessary device nodes. This step is not necessary for system not - having Digi PCI cards. - -3. This is because we forsee a time when buildPCI may auto-detect the - available Digi PCI cards and this would only work if the program is - executed after digiDload. - -4. A complete example is given in install.doc. - --------------CHANGES-------------------- - -All changes should be recorded here. All changes should be explained in -verbose detail. ------------------------------------------------------------------------ -Programmer : Ronnie Sanford -Date : June 1, 1996 -Description (Verbose) : Initial release of driver package. -Files affected : all -Release version : 1.0.0f (BETA) ------------------------------------------------------------------------ ------------------------------------------------------------------------ -Programmer : Ronnie Sanford -Date : August 7, 1996 -Description (Verbose) : Made several modifications to provide PCI and EISA - support: - - 1. We now allocate the termios structures based on - the maximum number of channels that COULD be - available to the system. We no longer use the - number of channels declared in epcaconfig.h - (NBDEVS) as the total channel number. This is - because this value does not represent channels - available to potential PCI cards. This new - larger value is also passed back to the os in - the num field of tty_driver. - - 2. Added code to copy the previous board structure - (Now called static_boards) into a new local - copy of the boards structure. This has been - done so that PCI cards may be added to this - board array and later referenced (And even - queried.). - - 3. Added code to pc_init that checks for supported - PCI cards. If found this code initializes a new - entry into the drivers local board structure - with the PCI cards address, and type, etc.. It - also bumps the card count (num_cards). - - 4. Modified code in post_fep_init so that when this - routine is executed the number of ports supported - by a particular PCI card will be determined and - loaded into the board structure. It would be - much better if this code was placed in pc_init - (Because we could then report to the os the true - number of ports available; not just the max), but - since the card has to be booted to determine the - number of ports it supports, we are forced to do it - after DIGI_INIT has called post_fep_init. In the - future we may attempt to read the num ports - attached directly (address 0x1ac). - - 5. Added board types to epca.h in support of various - PCI boards (Some of which do not exist yet). - Added procedures for these boards throughout the - code. Note, windowing is not necessary for PCI - boards. - - 6. Added code supporting the EISA/XEM. This included - modifying epca.h with the new board type and - adding this type into the driver. The EISA/XEM - is basically identical to the PC/XEM, other than - it's base address does not have to be (And cannot - be configured directly). - - 7. Modified digiConfig to prompt for EISA/XEM cards. - -Files affected : epca.c, epca.h, digi1.h, digiConfig -Release version : 1.0.0g (BETA) ------------------------------------------------------------------------ ------------------------------------------------------------------------ -Programmer : Ronnie Sanford -Date : August 21, 1996 -Description (Verbose) : Made the following modifications: - - 1. A problem affecting hard flow control was found - in the termios2digi_h routine. Specifically, - when the user activated hard flow control using - the CRTSCTS specification, the values used to - program hard flow control on the board were - incorrect. The solution was to change a line - that read "res |= ((ch->m_dtr) | (ch->m_rts));" - to "res |= ((ch->m_cts) | (ch->m_rts));" This - line only applies if cflag & CRTSCTS. Special - thanks to Matt Robinson (matt@mania.com.au) who - found and fixed this problem. - - 2. In previous betas the cud device was set to CLOCAL - on driver boot up. Likewise the ttyD device was - set to ~CLOCAL. This has been fixed in this driver. - Now ttyD is CLOCAL and cud is ~CLOCAL. The fix - for this can be found in pc_init. - - 3. In ditty.c many changes were made to eliminate bugs - and warning messages. Two ioctl calls were eliminated - as well a problem involving using the returned baud - index to determine the drivers baud rate. Newer - Linux kernels support higher baud rates by using - 0x1000 bit. When the returned value (ored with - 0x1000) was used to reference our fbaud table a - serious memory problem occurred. This has been fixed. - - 4. Added a request_region call to post_fep_init. This - should cause the i/o ports being used to be - registered with proc. - - 5. Modified digiConfig to set all cud and ttyD devices - to read/write all permission. - - 6. Developed a new apps called buildPCI that provides - an easy way to build device nodes for PCI cards. - - 7. Modified user.doc and technotes.doc document the - use of buildPCI. - -Files affected : epca.c, ditty.c, digiConfig, user.doc, technotes.doc -Release version : 1.0.0 (Official release) ------------------------------------------------------------------------ -Programmer : Ronnie Sanford -Date : August 21, 1996 -Description (Verbose) : Made the following modifications: - - 1. Removed code from pc_close which closes the - drivers line discipline and restores its original - line discipline. This is currently unnecessary, - though future fast cook enhancements may require - this. - - 2. Removed code in block_til_ready that set the - asyncflags to either ASYNC_CALLOUT_ACTIVE, or - ASYNC_NORMAL_ACTIVE. This code was redundant - as it already existed in block_til_ready. - - 3. Added code in block_til_ready to cause a return - prior to schedule being called if the device - was a CALLOUT device. CALLOUT devices never - block on CD. (This was a serious bug that - prevented the CALLOUT devices (ttyD) from - functioning properly in some instances. - - Make a change in the MODEMCHG_IND case of doevent - such that it does not require ASYNC_CALLOUT_ACTIVE - or ASYNC_NORMAL_ACTIVE to be set in order to - unblock an open (Using wait_interruptible). - - Thanks to Mike McLagan (mike.mclagan@linux.org) - for diagnosing and fixing this problem. - - 4. Made changes to the disposition of CLOCAL on - both SERIAL NORMAL and CALLOUT devices. Both - device types now have CLOCAL active at default. - This may be changed with a stty command. - - 5. Made changes to digiConfig such that it checks - major.h (If valid) for the correct major - numbers to use. - -Files affected : epca.c, digiConfig -Release version : 1.0.1a - - ------------------------------------------------------------------------ -Programmer : Ronnie Sanford -Date : September 17, 1996 -Description (Verbose) : Made the following modifications: - - 1. Modified pc_open such that it no longer checks - the cflag value returned by termios2digi_c for - CLOCAL. Digi hardware does not use this value - and thus termios2digi_c rightly screens this - value out. This driver checks for CLOCAL using - the drivers cflag value as known by the Linux OS. - (The value passed into termios2digi_c) - - 2. Modified termios2digi_c to screen out the - CBAUDEX in CBAUD. This error caused parity to - automaticaly be enabled on at higher baud rates. - - - 3. Added the "disable_bh()" call to the shutdown - subroutine. Hopefully this will allow the driver - to correctly clean up after itself when used as a - module. - - 4. Added support for the PC/XI and 64K PC/XE cards. - This involved primarily modifying digiDload to - initialize and boot the new cards; however - driver modifications were also required to - provide the proper windowing for the newly - supported cards. (Code was also added to - determine the memory segment of the XI card as - that card may have more than 64K. Currently - digiDload assumes a 64K XI card.) - - 5. Added subroutine called epca_setup that can be - called during LILO boot up. This provides the - user an easy way to change cards; without - running digiConfig and without recompiling the - kernel. Added code in pc_init and pc_open to - support the epca_setup routine. pc_init checks - the liloconfig flag (Which is set by epca_setup) - to determine if the driver is using the LILO - arguments. If not pc_init loads the board data - found in epcaconfig.h; if so it DOESN'T load - epcaconfig data depending on epca_setup to handle - board configuration. pc_open has been modified - such that it checks to ensure that no errors - occurred during the LILO boot process. If a - user attempts to boot the driver (via. LILO) - with incorrect data, the open will fail. - - 6. Modified the windowing routines pcxe_rxwinon - and pcxe_txwinon routines. A bug existed such - that those routines checked to see if the rxwin - and txwin flags were reset. If so they assumed - the board was an XI or 64K XE. Furthermore since - these flags were never initialized in our driver - sometimes they were 0 and therefore caused a - memory fault (Or at least a window overrun). This - code has been removed since the pcxe shares - nothing in common with the 64K XI and XE. - - 7. Added code in pc_init to set the memory_seg for - the various boards. This code was necessary to - correct a bug in the PCXE, PCXEVE code where - receive and transmit pointers were being calculated - from an uninitialized variable (memory_seg). - - 8. Modified digiConfig to allow 64K PC/XI and 64K - PC/XE cards to be configured. - - 9. Made changes to support the new 2.1.x development - kernel. In particular this required changing all - references to vremap to ioremap. - - 10. Modified digiConfig such that it now generates - node names corresponding to their internal - as opposed to the label on the port itself. Nodes - (ttyD?? and cud??) now start at 0. Example: - ttyD0 and cud0 represent port 1 on any supported - Digi product. A similar change has been made - in buildPCI.c. - - 12. At the early portion of post_fep_init if a PCI - card is detected a warning message could be given - incorrectly if 64 ports were attached to a PCI - card. The below line : - - epcaassert(bd->numports > 64,"PCI returned a invalid number of ports"); - - was changed to : - - epcaassert(bd->numports <= 64,"PCI returned a invalid number of ports"); - - Remember that epcaassert checks for NOT true. - Special thanks to Daniel Taylor for fixing this. - - 13. Modified the epcaparam routine. In version 100 - and 101a there was a line that looked like the - below: - - if (ch->omodem != mval) - - The problem with this line was that the first time - through omodem was not initialized. Secondly, since - many TIOC commands did not alter mval (They use - a different variable) changes made by these commands - could be lost. This line was changed to: - - mval ^= ch->modemfake & (mval ^ ch->modem); - - if (ch->omodem ^ mval) - - 14. Modified digiConfig in such a way that it checks - the version number of the kernel and if it finds - a 2.x.x kernel or higher it reads the necessary - major numbers for cud and ttyD devices from major.h. - This was also done in prior versions but these - versions required a #define which identified the - kernel as a version which did not have major numbers - assigned to Digi systems. This #define is no - longer required allowing the same source tree for - multiple kernel releases. - - 15. Used macros to replace kernel specific calls such - as put_fs_long, get_fs_long, put_user, and get_user - the kernel version is now detected and the macro - is defined as to correspond with the kernel it - is being compiled into. Again this was done to - allow one source tree for multiple kernel releases. - - 16. Added support for the new 2.1.x development kernels - to digiInstall. - -Files affected : epca.c, digiConfig -Release version : 1.1.0 ------------------------------------------------------------------------ -Programmer : Daniel Taylor -Date : April 25, 1997 -Description (Verbose) : Updated driver: - 1.

It monitors up - * to 8 voltages (including its own power source), up to three temperatures - * (its own plus up to two external ones) and up to two fans. The default - * configuration is 6 voltages, two temperatures and two fans (see below). - * Voltages are scaled internally with ratios such that the nominal value of - * each voltage correspond to a register value of 192 (which means a - * resolution of about 0.5% of the nominal value). Temperature values are - * reported with a 1 deg resolution and a 3-4 deg accuracy. Complete - * datasheet can be obtained from National's website at: - * http://www.national.com/pf/LM/LM87.html - * - * Some functions share pins, so not all functions are available at the same - * time. Which are depends on the hardware setup. This driver assumes that - * the BIOS configured the chip correctly. In that respect, it differs from - * the original driver (from lm_sensors for Linux 2.4), which would force the - * LM87 to an arbitrary, compile-time chosen mode, regardless of the actual - * chipset wiring. - * For reference, here is the list of exclusive functions: - * - in0+in5 (default) or temp3 - * - fan1 (default) or in6 - * - fan2 (default) or in7 - * - VID lines (default) or IRQ lines (not handled by this driver) - * - * The LM87 additionally features an analog output, supposedly usable to - * control the speed of a fan.

The LM90 is a sensor chip made by National - * Semiconductor. It reports up to two temperatures (its own plus up to - * one external one) with a 0.125 deg resolution (1 deg for local - * temperature) and a 3-4 deg accuracy. Complete datasheet can be - * obtained from National's website at: - * http://www.national.com/pf/LM/LM90.html - * - * This driver also supports the LM89 and LM99, two other sensor chips - * made by National Semiconductor. Both have an increased remote - * temperature measurement accuracy (1 degree), and the LM99 - * additionally shifts remote temperatures (measured and limits) by 16 - * degrees, which allows for higher temperatures measurement. The - * driver doesn't handle it since it can be done easily in user-space. - * Complete datasheets can be obtained from National's website at: - * http://www.national.com/pf/LM/LM89.html - * http://www.national.com/pf/LM/LM99.html - * Note that there is no way to differenciate between both chips. - * - * This driver also supports the LM86, another sensor chip made by - * National Semiconductor. It is exactly similar to the LM90 except it - * has a higher accuracy. - * Complete datasheet can be obtained from National's website at: - * http://www.national.com/pf/LM/LM86.html - * - * This driver also supports the ADM1032, a sensor chip made by Analog - * Devices. That chip is similar to the LM90, with a few differences - * that are not handled by this driver. Complete datasheet can be - * obtained from Analog's website at: - * http://products.analog.com/products/info.asp?product=ADM1032 - * Among others, it has a higher accuracy than the LM90, much like the - * LM86 does. - * - * This driver also supports the MAX6657, MAX6658 and MAX6659 sensor - * chips made by Maxim. These chips are similar to the LM86. Complete - * datasheet can be obtained at Maxim's website at: - * http://www.maxim-ic.com/quick_view2.cfm/qv_pk/2578 - * Note that there is no easy way to differenciate between the three - * variants. The extra address and features of the MAX6659 are not - * supported by this driver. - * - * This driver also supports the ADT7461 chip from Analog Devices but - * only in its "compatability mode". If an ADT7461 chip is found but - * is configured in non-compatible mode (where its temperature - * register values are decoded differently) it is ignored by this - * driver.

The luminance component (Y) is sampled at 13.5 MHz, while the two color difference signals, Cr and Cb are sampled at half that, or 6.75 MHz. The Cr and Cb samples are colocated with alternate Y samples, and they are taken at the same position on each line, such that one sample is coincident with the 50% point of the falling edge of analog sync.

If you can make the device raise an IRQ (and - that IRQ line isn't already being used), these routines will tell - you what IRQ line it's using -- perfect for those oh-so-cool boot-time - device probes! - - To use this, first call autoirq_setup(timeout). TIMEOUT is how many - 'jiffies' (1/100 sec.) to detect other devices that have active IRQ lines, - and can usually be zero at boot. 'autoirq_setup()' returns the bit - vector of nominally-available IRQ lines (lines may be physically in-use, - but not yet registered to a device). - Next, set up your device to trigger an interrupt. - Finally call autoirq_report(TIMEOUT) to find out which IRQ line was - most recently active. The TIMEOUT should usually be zero, but may - be set to the number of jiffies to wait for a slow device to raise an IRQ. - - The idea of using the setup timeout to filter out bogus IRQs came from - the serial driver. -*/ - - -#ifdef version -static const char *version= -"auto_irq.c:v1.11 Donald Becker (becker@scyld.com)"; -#endif - -#include -#include -#include -#include -#include -#include -#include - -static unsigned long irqs; - -void autoirq_setup(int waittime) -{ - irqs = probe_irq_on(); -} - -#define BUSY_LOOP_UNTIL(j) while ((long)(jiffies-(j)) < 0) ; -int autoirq_report(int waittime) -{ - unsigned long delay = jiffies + waittime; - BUSY_LOOP_UNTIL(delay) - return probe_irq_off(irqs); -} - -EXPORT_SYMBOL(autoirq_setup); -EXPORT_SYMBOL(autoirq_report); - - -/* - * Local variables: - * compile-command: "gcc -DKERNEL -Wall -O6 -fomit-frame-pointer -I/usr/src/linux/net/tcp -c auto_irq.c" - * version-control: t - * kept-new-versions: 5 - * c-indent-level: 4 - * tab-width: 4 - * End: - */ diff --git a/drivers/net/bagetlance.c b/drivers/net/bagetlance.c deleted file mode 100644 index 55a0f66f6..000000000 --- a/drivers/net/bagetlance.c +++ /dev/null @@ -1,1368 +0,0 @@ -/* - * bagetlance.c: Ethernet driver for VME Lance cards on Baget/MIPS - * This code stealed and adopted from linux/drivers/net/atarilance.c - * See that for author info - * - * Copyright (C) 1998 Gleb Raiko & Vladimir Roganov - */ - -/* - * Driver code for Baget/Lance taken from atarilance.c, which also - * works well in case of Besta.

Supported adapter types: - * - * S502A - * ES502A (S502E) - * S503 - * S507 - * S508 (S509) - * - * 3. S502A Notes: - * - * There is no separate DPM window enable/disable control in S502A. It - * opens immediately after a window number it written to the HMCR - * register. To close the window, HMCR has to be written a value - * ????1111b (e.g. 0x0F or 0xFF). - * - * S502A DPM window cannot be located at offset E000 (e.g. 0xAE000). - * - * There should be a delay of ??? before reading back S502A status - * register. - * - * 4. S502E Notes: - * - * S502E has a h/w bug: although default IRQ line state is HIGH, enabling - * interrupts by setting bit 1 of the control register (BASE) to '1' - * causes it to go LOW! Therefore, disabling interrupts by setting that - * bit to '0' causes low-to-high transition on IRQ line (ghosty - * interrupt). The same occurs when disabling CPU by resetting bit 0 of - * CPU control register (BASE+3) - see the next note. - * - * S502E CPU and DPM control is limited: - * - * o CPU cannot be stopped independently. Resetting bit 0 of the CPUi - * control register (BASE+3) shuts the board down entirely, including - * DPM; - * - * o DPM access cannot be controlled dynamically. Ones CPU is started, - * bit 1 of the control register (BASE) is used to enable/disable IRQ, - * so that access to shared memory cannot be disabled while CPU is - * running. - ****************************************************************************/ - -#define _LINUX_ - -#if defined(_LINUX_) /****** Linux *******************************/ - -#include -#include /* printk(), and other useful stuff */ -#include /* offsetof(), etc. */ -#include /* return codes */ -#include /* inline memset(), etc. */ -#include /* support for loadable modules */ -#include /* for jiffies, HZ, etc. */ -#include /* API definitions */ -#include /* SDLA firmware module definitions */ -#include /* SDLA PCI hardware definitions */ -#include /* PCI defines and function prototypes */ -#include /* for inb(), outb(), etc. */ - -#define _INB(port) (inb(port)) -#define _OUTB(port, byte) (outb((byte),(port))) -#define SYSTEM_TICK jiffies - -#include - - -#elif defined(_SCO_UNIX_) /****** SCO Unix ****************************/ - -#if !defined(INKERNEL) -#error This code MUST be compiled in kernel mode!

Specifically, -// every time a link re-init (e.g. LIP) takes place, all SCSI I/O has to be -// suspended until the login sequences have been completed. Login commands -// are frames just like SCSI commands are frames; they are subject to the same -// timeout issues and delays. Also, various specs provide up to 2 seconds for -// devices to log back in (i.e. respond with ACC to a login frame), so I/O to -// that device has to be suspended. -// A serious problem here occurs on highly loaded FC-AL systems. If our FC port -// has a low priority (e.g. high arbitrated loop physical address, alpa), and -// some other device is hogging bandwidth (permissible under FC-AL), we might -// time out thinking the link is hung, when it's simply busy. Many such -// considerations complicate the design. Although Tachyon assumes control -// (in silicon) for many link-specific issues, the Linux driver is left with the -// rest, which turns out to be a difficult, time critical chore. - -// These "worker" functions will handle things like FC Logins; all -// processes with I/O to our device must wait for the Login to complete -// and (if successful) I/O to resume. In the event of a malfunctioning or -// very busy loop, it may take hundreds of millisecs or even seconds to complete -// a frame send. We don't want to hang up the entire server (and all -// processes which don't depend on Fibre) during this wait. - -// The Tachyon chip can have around 30,000 I/O operations ("exchanges") -// open at one time. However, each exchange must be initiated -// synchronously (i.e. each of the 30k I/O had to be started one at a -// time by sending a starting frame via Tachyon's outbound que). - -// To accommodate kernel "module" build, this driver limits the exchanges -// to 256, because of the contiguous physical memory limitation of 128M. - -// Typical FC Exchanges are opened presuming the FC frames start without errors, -// while Exchange completion is handled in the interrupt handler. This -// optimizes performance for the "everything's working" case. -// However, when we have FC related errors or hot plugging of FC ports, we pause -// I/O and handle FC-specific tasks in the worker thread. These FC-specific -// functions will handle things like FC Logins and Aborts. As the Login sequence -// completes to each and every target, I/O can resume to that target. - -// Our kernel "worker thread" must share the HBA with threads calling -// "queuecommand". We define a "BoardLock" semaphore which indicates -// to "queuecommand" that the HBA is unavailable, and Cmnds are added to a -// board lock Q. When the worker thread finishes with the board, the board -// lock Q commands are completed with status causing immediate retry. -// Typically, the board is locked while Logins are in progress after an -// FC Link Down condition. When Cmnds are re-queued after board lock, the -// particular Scsi channel/target may or may not have logged back in. When -// the device is waiting for login, the "prli" flag is clear, in which case -// commands are passed to a Link Down Q. Whenever the login finally completes, -// the LinkDown Q is completed, again with status causing immediate retry. -// When FC devices are logged in, we build and start FC commands to the -// devices. - -// NOTE!!

It is however impractical to - * transmit/receive USB data directly into and out of the ring buffer, - * due to alignment and synchronisation issues. Instead, the ring buffer - * feeds a constant time delay line that handles the USB issues. - * - * Now we first try to find an alternate setting that exactly matches - * the sample format requested by the user. If we find one, we do not - * need to perform any sample rate conversions. If there is no matching - * altsetting, we choose the closest one and perform sample format - * conversions. We never do sample rate conversion; these are too - * expensive to be performed in the kernel. - * - * Current status: no known HCD-specific issues. - * - * Generally: Due to the brokenness of the Audio Class spec - * it seems generally impossible to write a generic Audio Class driver, - * so a reasonable driver should implement the features that are actually - * used. - * - * Parsing implementation issues - * - * One cannot reasonably parse the AudioClass descriptors linearly. - * Therefore the current implementation features routines to look - * for a specific descriptor in the descriptor list. - * - * How does the parsing work? First, all interfaces are searched - * for an AudioControl class interface. If found, the config descriptor - * that belongs to the current configuration is searched and - * the HEADER descriptor is found. It contains a list of - * all AudioStreaming and MIDIStreaming devices. This list is then walked, - * and all AudioStreaming interfaces are classified into input and output - * interfaces (according to the endpoint0 direction in altsetting1) (MIDIStreaming - * is currently not supported). The input & output list is then used - * to group inputs and outputs together and issued pairwise to the - * AudioStreaming class parser. Finally, all OUTPUT_TERMINAL descriptors - * are walked and issued to the mixer construction routine. - * - * The AudioStreaming parser simply enumerates all altsettings belonging - * to the specified interface. It looks for AS_GENERAL and FORMAT_TYPE - * class specific descriptors to extract the sample format/sample rate - * data. Only sample format types PCM and PCM8 are supported right now, and - * only FORMAT_TYPE_I is handled. The isochronous data endpoint needs to - * be the first endpoint of the interface, and the optional synchronisation - * isochronous endpoint the second one. - * - * Mixer construction works as follows: The various TERMINAL and UNIT - * descriptors span a tree from the root (OUTPUT_TERMINAL) through the - * intermediate nodes (UNITs) to the leaves (INPUT_TERMINAL). We walk - * that tree in a depth first manner. FEATURE_UNITs may contribute volume, - * bass and treble sliders to the mixer, MIXER_UNITs volume sliders. - * The terminal type encoded in the INPUT_TERMINALs feeds a heuristic - * to determine "meaningful" OSS slider numbers, however we will see - * how well this works in practice. Other features are not used at the - * moment, they seem less often used. Also, it seems difficult at least - * to construct recording source switches from SELECTOR_UNITs, but - * since there are not many USB ADC's available, we leave that for later. - */ - -/*****************************************************************************/ - -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include - -#include "audio.h" - -/* - * Version Information - */ -#define DRIVER_VERSION "v1.0.0" -#define DRIVER_AUTHOR "Alan Cox , Thomas Sailer (sailer@ife.ee.ethz.ch)" -#define DRIVER_DESC "USB Audio Class driver" - -#define AUDIO_DEBUG 1 - -#define SND_DEV_DSP16 5 - -#define dprintk(x) - -/* --------------------------------------------------------------------- */ - -/* - * Linked list of all audio devices... - */ -static struct list_head audiodevs = LIST_HEAD_INIT(audiodevs);

Well, it used to be simple, but alas... In this - module, 3 buffers schemes are used to get the data from the USB bus to - the user program. The first scheme involves the ISO buffers (called thus - since they transport ISO data from the USB controller), and not really - interesting. Suffices to say the data from this buffer is quickly - gathered in an interrupt handler (pwc_isoc_handler) and placed into the - frame buffer. - - The frame buffer is the second scheme, and is the central element here. - It collects the data from a single frame from the camera (hence, the - name). Frames are delimited by the USB camera with a short USB packet, - so that's easy to detect. The frame buffers form a list that is filled - by the camera+USB controller and drained by the user process through - either read() or mmap(). - - The image buffer is the third scheme, in which frames are decompressed - and converted into planar format. For mmap() there is more than - one image buffer available. - - The frame buffers provide the image buffering. In case the user process - is a bit slow, this introduces lag and some undesired side-effects. - The problem arises when the frame buffer is full. I used to drop the last - frame, which makes the data in the queue stale very quickly. But dropping - the frame at the head of the queue proved to be a litte bit more difficult. - I tried a circular linked scheme, but this introduced more problems than - it solved. - - Because filling and draining are completely asynchronous processes, this - requires some fiddling with pointers and mutexes. - - Eventually, I came up with a system with 2 lists: an 'empty' frame list - and a 'full' frame list: - * Initially, all frame buffers but one are on the 'empty' list; the one - remaining buffer is our initial fill frame. - * If a frame is needed for filling, we try to take it from the 'empty' - list, unless that list is empty, in which case we take the buffer at - the head of the 'full' list. - * When our fill buffer has been filled, it is appended to the 'full' - list. - * If a frame is needed by read() or mmap(), it is taken from the head of - the 'full' list, handled, and then appended to the 'empty' list. If no - buffer is present on the 'full' list, we wait. - The advantage is that the buffer that is currently being decompressed/ - converted, is on neither list, and thus not in our way (any other scheme - I tried had the problem of old data lingering in the queue). - - Whatever strategy you choose, it always remains a tradeoff: with more - frame buffers the chances of a missed frame are reduced. On the other - hand, on slower machines it introduces lag because the queue will - always be full. - */ - -/** - \brief Find next frame buffer to fill.

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. If - you want to turn the initialization and probing tracing off, set trace=0. - The default value for trace is 35 (0x23). - - - -Example: - - # modprobe pwc size=cif fps=15 power_save=1 - -The fbufs, mbufs and trace parameters are global and apply to all connected -cameras. Each camera has its own set of buffers. - -size and fps only specify defaults when you open() the device; this is to -accommodate some tools that don't set the size. You can change these -settings after open() with the Video4Linux ioctl() calls. The default of -defaults is QCIF size at 10 fps. - -The compression parameter is semiglobal; it sets the initial compression -preference for all camera's, but this parameter can be set per camera with -the VIDIOCPWCSCQUAL ioctl() call. - -All parameters are optional. - diff --git a/drivers/usb/media/pwc/pwc-ctrl.c b/drivers/usb/media/pwc/pwc-ctrl.c deleted file mode 100644 index 530991909..000000000 --- a/drivers/usb/media/pwc/pwc-ctrl.c +++ /dev/null @@ -1,1628 +0,0 @@ -/* Driver for Philips webcam - Functions that send various control messages to the webcam, including - video modes. - (C) 1999-2003 Nemosoft Unv. - (C) 2004 Luc Saillard (luc@saillard.org) - - NOTE: this version of pwc is an unofficial (modified) release of pwc & pcwx - driver and thus may have bugs that are not present in the original version. - Please send bug reports and support requests to . - - NOTE: this version of pwc is an unofficial (modified) release of pwc & pcwx - driver and thus may have bugs that are not present in the original version. - Please send bug reports and support requests to . - The decompression routines have been implemented by reverse-engineering the - Nemosoft binary pwcx module.

Well, it used to be simple, but alas... In this - module, 3 buffers schemes are used to get the data from the USB bus to - the user program. The first scheme involves the ISO buffers (called thus - since they transport ISO data from the USB controller), and not really - interesting. Suffices to say the data from this buffer is quickly - gathered in an interrupt handler (pwc_isoc_handler) and placed into the - frame buffer. - - The frame buffer is the second scheme, and is the central element here. - It collects the data from a single frame from the camera (hence, the - name). Frames are delimited by the USB camera with a short USB packet, - so that's easy to detect. The frame buffers form a list that is filled - by the camera+USB controller and drained by the user process through - either read() or mmap(). - - The image buffer is the third scheme, in which frames are decompressed - and converted into planar format. For mmap() there is more than - one image buffer available. - - The frame buffers provide the image buffering. In case the user process - is a bit slow, this introduces lag and some undesired side-effects. - The problem arises when the frame buffer is full. I used to drop the last - frame, which makes the data in the queue stale very quickly. But dropping - the frame at the head of the queue proved to be a litte bit more difficult. - I tried a circular linked scheme, but this introduced more problems than - it solved. - - Because filling and draining are completely asynchronous processes, this - requires some fiddling with pointers and mutexes. - - Eventually, I came up with a system with 2 lists: an 'empty' frame list - and a 'full' frame list: - * Initially, all frame buffers but one are on the 'empty' list; the one - remaining buffer is our initial fill frame. - * If a frame is needed for filling, we try to take it from the 'empty' - list, unless that list is empty, in which case we take the buffer at - the head of the 'full' list. - * When our fill buffer has been filled, it is appended to the 'full' - list. - * If a frame is needed by read() or mmap(), it is taken from the head of - the 'full' list, handled, and then appended to the 'empty' list. If no - buffer is present on the 'full' list, we wait. - The advantage is that the buffer that is currently being decompressed/ - converted, is on neither list, and thus not in our way (any other scheme - I tried had the problem of old data lingering in the queue). - - Whatever strategy you choose, it always remains a tradeoff: with more - frame buffers the chances of a missed frame are reduced. On the other - hand, on slower machines it introduces lag because the queue will - always be full. - */ - -/** - \brief Find next frame buffer to fill.
