--------------------------------------------------------------------------
-Release Notes for Linux on Intel's IXP4xx Network Processor
-
-Maintained by Deepak Saxena <dsaxena@plexity.net>
--------------------------------------------------------------------------
-
-1. Overview
-
-Intel's IXP4xx network processor is a highly integrated SOC that
-is targeted for network applications, though it has become popular
-in industrial control and other areas due to low cost and power
-consumption. The IXP4xx family currently consists of several processors
-that support different network offload functions such as encryption,
-routing, firewalling, etc. For more information on the various
-versions of the CPU, see:
-
- http://developer.intel.com/design/network/products/npfamily/ixp4xx.htm
-
-Intel also made the IXCP1100 CPU for sometime which is an IXP4xx
-stripped of much of the network intelligence.
-
-2. Linux Support
-
-Linux currently supports the following features on the IXP4xx chips:
-
-- Dual serial ports
-- PCI interface
-- Flash access (MTD/JFFS)
-- I2C through GPIO
-- GPIO for input/output/interrupts
- See include/asm-arm/arch-ixp4xx/platform.h for access functions.
-- Timers (watchdog, OS)
-
-The following components of the chips are not supported by Linux and
-require the use of Intel's propietary CSR softare:
-
-- USB device interface
-- Network interfaces (HSS, Utopia, NPEs, etc)
-- Network offload functionality
-
-If you need to use any of the above, you need to download Intel's
-software from:
-
- http://developer.intel.com/design/network/products/npfamily/ixp425swr1.htm
-
-DO NOT POST QUESTIONS TO THE LINUX MAILING LISTS REGARDING THE PROPIETARY
-SOFTWARE.
-
-There are several websites that provide directions/pointers on using
-Intel's software:
-
-http://ixp4xx-osdg.sourceforge.net/
- Open Source Developer's Guide for using uClinux and the Intel libraries
-
-http://gatewaymaker.sourceforge.net/
- Simple one page summary of building a gateway using an IXP425 and Linux
-
-http://ixp425.sourceforge.net/
- ATM device driver for IXP425 that relies on Intel's libraries
-
-3. Known Issues/Limitations
-
-3a. Limited inbound PCI window
-
-The IXP4xx family allows for up to 256MB of memory but the PCI interface
-can only expose 64MB of that memory to the PCI bus. This means that if
-you are running with > 64MB, all PCI buffers outside of the accessible
-range will be bounced using the routines in arch/arm/common/dmabounce.c.
-
-3b. Limited outbound PCI window
-
-IXP4xx provides two methods of accessing PCI memory space:
-
-1) A direct mapped window from 0x48000000 to 0x4bffffff (64MB).
- To access PCI via this space, we simply ioremap() the BAR
- into the kernel and we can use the standard read[bwl]/write[bwl]
- macros. This is the preffered method due to speed but it
- limits the system to just 64MB of PCI memory. This can be
- problamatic if using video cards and other memory-heavy devices.
-
-2) If > 64MB of memory space is required, the IXP4xx can be
- configured to use indirect registers to access PCI This allows
- for up to 128MB (0x48000000 to 0x4fffffff) of memory on the bus.
- The disadvantadge of this is that every PCI access requires
- three local register accesses plus a spinlock, but in some
- cases the performance hit is acceptable. In addition, you cannot
- mmap() PCI devices in this case due to the indirect nature
- of the PCI window.
-
-By default, the direct method is used for performance reasons. If
-you need more PCI memory, enable the IXP4XX_INDIRECT_PCI config option.
-
-3c. GPIO as Interrupts
-
-Currently the code only handles level-sensitive GPIO interrupts
-
-4. Supported platforms
-
-ADI Engineering Coyote Gateway Reference Platform
-http://www.adiengineering.com/productsCoyote.html
-
- The ADI Coyote platform is reference design for those building
- small residential/office gateways. One NPE is connected to a 10/100
- interface, one to 4-port 10/100 switch, and the third to and ADSL
- interface. In addition, it also supports to POTs interfaces connected
- via SLICs. Note that those are not supported by Linux ATM. Finally,
- the platform has two mini-PCI slots used for 802.11[bga] cards.
- Finally, there is an IDE port hanging off the expansion bus.
-
-Gateworks Avila Network Platform
-http://www.gateworks.com/avila_sbc.htm
-
- The Avila platform is basically and IXDP425 with the 4 PCI slots
- replaced with mini-PCI slots and a CF IDE interface hanging off
- the expansion bus.
-
-Intel IXDP425 Development Platform
-http://developer.intel.com/design/network/products/npfamily/ixdp425.htm
-
- This is Intel's standard reference platform for the IXDP425 and is
- also known as the Richfield board. It contains 4 PCI slots, 16MB
- of flash, two 10/100 ports and one ADSL port.
-
-Motorola PrPMC1100 Processor Mezanine Card
-http://www.fountainsys.com/datasheet/PrPMC1100.pdf
-
- The PrPMC1100 is based on the IXCP1100 and is meant to plug into
- and IXP2400/2800 system to act as the system controller. It simply
- contains a CPU and 16MB of flash on the board and needs to be
- plugged into a carrier board to function. Currently Linux only
- supports the Motorola PrPMC carrier board for this platform.
- See https://mcg.motorola.com/us/ds/pdf/ds0144.pdf for info
- on the carrier board.
-
-5. TODO LIST
-
-- Add support for Coyote IDE
-- Add support for edge-based GPIO interrupts
-- Add support for CF IDE on expansion bus
-
-6. Thanks

-README on the SDRAM Controller for the LH7a40X
-==============================================
-
-The standard configuration for the SDRAM controller generates a sparse
-memory array. The precise layout is determined by the SDRAM chips. A
-default kernel configuration assembles the discontiguous memory
-regions into separate memory nodes via the NUMA (Non-Uniform Memory
-Architecture) facilities. In this default configuration, the kernel
-is forgiving about the precise layout. As long as it is given an
-accurate picture of available memory by the bootloader the kernel will
-execute correctly.
-
-The SDRC supports a mode where some of the chip select lines are
-swapped in order to make SDRAM look like a synchronous ROM. Setting
-this bit means that the RAM will present as a contiguous array. Some
-programmers prefer this to the discontiguous layout. Be aware that
-may be a penalty for this feature where some some configurations of
-memory are significantly reduced; i.e. 64MiB of RAM appears as only 32
-MiB.
-
-There are a couple of configuration options to override the default
-behavior. When the SROMLL bit is set and memory appears as a
-contiguous array, there is no reason to support NUMA.
-CONFIG_LH7A40X_CONTIGMEM disables NUMA support. When physical memory
-is discontiguous, the memory tables are organized such that there are
-two banks per nodes with a small gap between them. This layout wastes
-some kernel memory for page tables representing non-existent memory.
-CONFIG_LH7A40X_ONE_BANK_PER_NODE optimizes the node tables such that
-there are no gaps. These options control the low level organization
-of the memory management tables in ways that may prevent the kernel
-from booting or may cause the kernel to allocated excessively large
-page tables. Be warned. Only change these options if you know what
-you are doing. The default behavior is a reasonable compromise that
-will suit all users.
-
---
-
-A typical 32MiB system with the default configuration options will
-find physical memory managed as follows.
-
- node 0: 0xc0000000 4MiB
- 0xc1000000 4MiB
- node 1: 0xc4000000 4MiB
- 0xc5000000 4MiB
- node 2: 0xc8000000 4MiB
- 0xc9000000 4MiB
- node 3: 0xcc000000 4MiB
- 0xcd000000 4MiB
-
-Setting CONFIG_LH7A40X_ONE_BANK_PER_NODE will put each bank into a
-separate node.

-Release notes for Linux Kernel VFP support code
------------------------------------------------
-
-Date: 20 May 2004
-Author: Russell King
-
-This is the first release of the Linux Kernel VFP support code. It
-provides support for the exceptions bounced from VFP hardware found
-on ARM926EJ-S.
-
-This release has been validated against the SoftFloat-2b library by
-John R. Hauser using the TestFloat-2a test suite. Details of this
-library and test suite can be found at:
-
- http://www.cs.berkeley.edu/~jhauser/arithmetic/SoftFloat.html
-
-The operations which have been tested with this package are:
-
- - fdiv
- - fsub
- - fadd
- - fmul
- - fcmp
- - fcmpe
- - fcvtd
- - fcvts
- - fsito
- - ftosi
- - fsqrt
-
-All the above pass softfloat tests with the following exceptions:
-
-- fadd/fsub shows some differences in the handling of +0 / -0 results
- when input operands differ in signs.
-- the handling of underflow exceptions is slightly different. If a
- result underflows before rounding, but becomes a normalised number
- after rounding, we do not signal an underflow exception.
-
-Other operations which have been tested by basic assembly-only tests
-are:
-
- - fcpy
- - fabs
- - fneg
- - ftoui
- - ftosiz
- - ftouiz
-
-The combination operations have not been tested:
-
- - fmac
- - fnmac
- - fmsc
- - fnmsc
- - fnmul

-Anticipatory IO scheduler
--------------------------
-Nick Piggin <piggin@cyberone.com.au> 13 Sep 2003
-
-Attention! Database servers, especially those using "TCQ" disks should
-investigate performance with the 'deadline' IO scheduler. Any system with high
-disk performance requirements should do so, in fact.
-
-If you see unusual performance characteristics of your disk systems, or you
-see big performance regressions versus the deadline scheduler, please email
-me. Database users don't bother unless you're willing to test a lot of patches
-from me ;) its a known issue.
-
-Also, users with hardware RAID controllers, doing striping, may find
-highly variable performance results with using the as-iosched. The
-as-iosched anticipatory implementation is based on the notion that a disk
-device has only one physical seeking head. 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.

-Deadline IO scheduler tunables
-==============================
-
-This little file attempts to document how the deadline io scheduler works.
-In particular, it will clarify the meaning of the exposed tunables that may be
-of interest to power users.
-
-Each io queue has a set of io scheduler tunables associated with it. These
-tunables control how the io scheduler works. You can find these entries
-in:
-
-/sys/block/<device>/iosched
-
-assuming that you have sysfs mounted on /sys. If you don't have sysfs mounted,
-you can do so by typing:
-
-# mount none /sys -t sysfs
-
-
-********************************************************************************
-
-
-read_expire (in ms)
------------
-
-The goal of the deadline io scheduler is to attempt to guarentee a start
-service time for a request. As we focus mainly on read latencies, this is
-tunable. When a read request first enters the io scheduler, it is assigned
-a deadline that is the current time + the read_expire value in units of
-miliseconds.
-
-
-write_expire (in ms)
------------
-
-Similar to read_expire mentioned above, but for writes.
-
-
-fifo_batch
-----------
-
-When a read request expires its deadline, we must move some requests from
-the sorted io scheduler list to the block device dispatch queue. fifo_batch
-controls how many requests we move, based on the cost of each request. A
-request is either qualified as a seek or a stream. The io scheduler knows
-the last request that was serviced by the drive (or will be serviced right
-before this one). See seek_cost and stream_unit.
-
-
-write_starved (number of dispatches)
--------------
-
-When we have to move requests from the io scheduler queue to the block
-device dispatch queue, we always give a preference to reads. However, we
-don't want to starve writes indefinitely either. So writes_starved controls
-how many times we give preference to reads over writes. When that has been
-done writes_starved number of times, we dispatch some writes based on the
-same criteria as reads.
-
-
-front_merges (bool)
-------------
-
-Sometimes it happens that a request enters the io scheduler that is contigious
-with a request that is already on the queue. Either it fits in the back of that
-request, or it fits at the front. That is called either a back merge candidate
-or a front merge candidate. Due to the way files are typically laid out,
-back merges are much more common than front merges. For some work loads, you
-may even know that it is a waste of time to spend any time attempting to
-front merge requests. Setting front_merges to 0 disables this functionality.
-Front merges may still occur due to the cached last_merge hint, but since
-that comes at basically 0 cost we leave that on. We simply disable the
-rbtree front sector lookup when the io scheduler merge function is called.

-Dm-io can read from one io_region or write to one or more io_regions. Writes
-to multiple regions are specified by an array of io_region structures.
-
-The first I/O service type takes a list of memory pages as the data buffer for

-The third I/O service type takes a pointer to a vmalloc'd memory buffer as the

-memory pages.

-Callers of the asynchronous I/O services must include the name of a completion
-callback routine and a pointer to some context data for the I/O.
-
- typedef void (*io_notify_fn)(unsigned long error, void *context);
-
-The "error" parameter in this callback, as well as the "*error" parameter in
-all of the synchronous versions, is a bitset (instead of a simple error value).
-In the case of an write-I/O to multiple regions, this bitset allows dm-io to
-indicate success or failure on each individual region.
-
-Before using any of the dm-io services, the user should call dm_io_get()
-and specify the number of pages they expect to perform I/O on concurrently.
-Dm-io will attempt to resize its mempool to make sure enough pages are
-always available in order to avoid unnecessary waiting while performing I/O.
-
-When the user is finished using the dm-io services, they should call
-dm_io_put() and specify the same number of pages that were given on the
-dm_io_get() call.

-kcopyd
-======
-
-Kcopyd provides the ability to copy a range of sectors from one block-device
-to one or more other block-devices, with an asynchronous completion
-notification. It is used by dm-snapshot and dm-mirror.
-
-Users of kcopyd must first create a client and indicate how many memory pages
-to set aside for their copy jobs. This is done with a call to
-kcopyd_client_create().
-
- int kcopyd_client_create(unsigned int num_pages,
- struct kcopyd_client **result);
-
-To start a copy job, the user must set up io_region structures to describe
-the source and destinations of the copy. Each io_region indicates a
-block-device along with the starting sector and size of the region. The source
-of the copy is given as one io_region structure, and the destinations of the
-copy are given as an array of io_region structures.
-
- struct io_region {
- struct block_device *bdev;
- sector_t sector;
- sector_t count;
- };
-
-To start the copy, the user calls kcopyd_copy(), passing in the client
-pointer, pointers to the source and destination io_regions, the name of a
-completion callback routine, and a pointer to some context data for the copy.
-
- int kcopyd_copy(struct kcopyd_client *kc, struct io_region *from,

- unsigned int flags, kcopyd_notify_fn fn, void *context);
-
- typedef void (*kcopyd_notify_fn)(int read_err, unsigned int write_err,
- void *context);
-
-When the copy completes, kcopyd will call the user's completion routine,
-passing back the user's context pointer. It will also indicate if a read or
-write error occurred during the copy.
-
-When a user is done with all their copy jobs, they should call
-kcopyd_client_destroy() to delete the kcopyd client, which will release the
-associated memory pages.
-
- void kcopyd_client_destroy(struct kcopyd_client *kc);

-dm-zero
-=======
-
-Device-Mapper's "zero" target provides a block-device that always returns
-zero'd data on reads and silently drops writes. This is similar behavior to
-/dev/zero, but as a block-device instead of a character-device.
-
-Dm-zero has no target-specific parameters.
-
-One very interesting use of dm-zero is for creating "sparse" devices in
-conjunction with dm-snapshot. A sparse device reports a device-size larger
-than the amount of actual storage space available for that device. A user can
-write data anywhere within the sparse device and read it back like a normal
-device. Reads to previously unwritten areas will return a zero'd buffer. When
-enough data has been written to fill up the actual storage space, the sparse
-device is deactivated. This can be very useful for testing device and
-filesystem limitations.
-
-To create a sparse device, start by creating a dm-zero device that's the
-desired size of the sparse device. For this example, we'll assume a 10TB
-sparse device.
-
-TEN_TERABYTES=`expr 10 \* 1024 \* 1024 \* 1024 \* 2` # 10 TB in sectors
-echo "0 $TEN_TERABYTES zero" | dmsetup create zero1
-
-Then create a snapshot of the zero device, using any available block-device as
-the COW device. The size of the COW device will determine the amount of real
-space available to the sparse device. For this example, we'll assume /dev/sdb1
-is an available 10GB partition.
-
-echo "0 $TEN_TERABYTES snapshot /dev/mapper/zero1 /dev/sdb1 p 128" | \
- dmsetup create sparse1
-
-This will create a 10TB sparse device called /dev/mapper/sparse1 that has
-10GB of actual storage space available. If more than 10GB of data is written
-to this device, it will start returning I/O errors.

-
-What is sisfb?
-==============
-
-sisfb is a framebuffer device driver for SiS (Silicon Integrated Systems)
-graphics chips. Supported are:
-
-- SiS 300 series: SiS 300/305, 540, 630(S), 730(S)
-- SiS 315 series: SiS 315/H/PRO, 55x, (M)65x, 740, (M)661(F/M)X, (M)741(GX)
-- SiS 330 series: SiS 330 ("Xabre"), (M)760
-
-
-Why do I need a framebuffer driver?
-===================================
-
-sisfb is eg. useful if you want a high-resolution text console. Besides that,
-sisfb is required to run DirectFB (which comes with an additional, dedicated
-driver for the 315 series).
-
-On the 300 series, sisfb on kernels older than 2.6.3 furthermore plays an
-important role in connection with DRM/DRI: Sisfb manages the memory heap
-used by DRM/DRI for 3D texture and other data. This memory management is
-required for using DRI/DRM.
-
-Kernels >= around 2.6.3 do not need sisfb any longer for DRI/DRM memory
-management. The SiS DRM driver has been updated and features a memory manager
-of its own (which will be used if sisfb is not compiled). So unless you want
-a graphical console, you don't need sisfb on kernels >=2.6.3.
-
-Sidenote: Since this seems to be a commonly made mistake: sisfb and vesafb
-cannot be active at the same time! Do only select one of them in your kernel
-configuration.
-
-
-How are parameters passed to sisfb?
-===================================
-
-Well, it depends: If compiled statically into the kernel, use lilo's append
-statement to add the parameters to the kernel command line. Please see lilo's
-(or GRUB's) documentation for more information. If sisfb is a kernel module,
-parameters are given with the modprobe (or insmod) command.
-
-Example for sisfb as part of the static kernel: Add the following line to your
-lilo.conf:
-
- append="video=sisfb:mode:1024x768x16,mem:12288,rate:75"
-
-Example for sisfb as a module: Start sisfb by typing
-
- modprobe sisfb mode=1024x768x16 rate=75 mem=12288
-
-A common mistake is that folks use a wrong parameter format when using the
-driver compiled into the kernel. Please note: If compiled into the kernel,
-the parameter format is video=sisfb:mode:none or video=sisfb:mode:1024x768x16
-(or whatever mode you want to use, alternatively using any other format
-described above or the vesa keyword instead of mode). If compiled as a module,
-the parameter format reads mode=none or mode=1024x768x16 (or whatever mode you
-want to use). Using a "=" for a ":" (and vice versa) is a huge difference!
-Additionally: If you give more than one argument to the in-kernel sisfb, the
-arguments are separated with ",". For example:
-
- video=sisfb:mode:1024x768x16,rate:75,mem:12288
-
-
-How do I use it?
-================
-
-Preface statement: This file only covers very little of the driver's
-capabilities and features. Please refer to the author's and maintainer's
-website at http://www.winischhofer.net/linuxsisvga.shtml for more
-information. Additionally, "modinfo sisfb" gives an overview over all
-supported options including some explanation.
-
-The desired display mode can be specified using the keyword "mode" with
-a parameter in one of the follwing formats:
- - XxYxDepth or
- - XxY-Depth or
- - XxY-Depth@Rate or
- - XxY
- - or simply use the VESA mode number in hexadecimal or decimal.
-
-For example: 1024x768x16, 1024x768-16@75, 1280x1024-16. If no depth is
-specified, it defaults to 8. If no rate is given, it defaults to 60Hz. Depth 32
-means 24bit color depth (but 32 bit framebuffer depth, which is not relevant
-to the user).
-
-Additionally, sisfb understands the keyword "vesa" followed by a VESA mode
-number in decimal or hexadecimal. For example: vesa=791 or vesa=0x117. Please
-use either "mode" or "vesa" but not both.
-
-Linux 2.4 only: If no mode is given, sisfb defaults to "no mode" (mode=none) if
-compiled as a module; if sisfb is statically compiled into the kernel, it
-defaults to 800x600x8 unless CRT2 type is LCD, in which case the LCD's native
-resolution is used. If you want to switch to a different mode, use the fbset
-shell command.
-
-Linux 2.6 only: If no mode is given, sisfb defaults to 800x600x8 unless CRT2
-type is LCD, in which case it defaults to the LCD's native resolution. If
-you want to switch to another mode, use the stty shell command.
-
-You should compile in both vgacon (to boot if you remove you SiS card from
-your system) and sisfb (for graphics mode). Under Linux 2.6, also "Framebuffer
-console support" (fbcon) is needed for a graphical console.
-
-You should *not* compile-in vesafb. And please do not use the "vga=" keyword
-in lilo's or grub's configuration file; mode selection is done using the
-"mode" or "vesa" keywords as a parameter. See above and below.
-
-
-X11
-===
-
-If using XFree86 or X.org, it is recommended that you don't use the "fbdev"
-driver but the dedicated "sis" X driver. The "sis" X driver and sisfb are
-developed by the same person (Thomas Winischhofer) and cooperate well with
-each other.
-
-
-SVGALib
-=======
-
-SVGALib, if directly accessing the hardware, never restores the screen
-correctly, especially on laptops or if the output devices are LCD or TV.
-Therefore, use the chipset "FBDEV" in SVGALib configuration. This will make
-SVGALib use the framebuffer device for mode switches and restoration.
-
-
-Configuration
-=============
-
-(Some) accepted options:
-
-off - Disable sisfb. This option is only understood if sisfb is
- in-kernel, not a module.
-mem:X - size of memory for the console, rest will be used for DRI/DRM. X
- is in kilobytes. On 300 series, the default is 4096, 8192 or
- 16384 (each in kilobyte) depending on how much video ram the card
- has. On 315/330 series, the default is the maximum available ram
- (since DRI/DRM is not supported for these chipsets).
-noaccel - do not use 2D acceleration engine. (Default: use acceleration)
-noypan - disable y-panning and scroll by redrawing the entire screen.
- This is much slower than y-panning. (Default: use y-panning)
-vesa:X - selects startup videomode. X is number from 0 to 0x1FF and
- represents the VESA mode number (can be given in decimal or
- hexadecimal form, the latter prefixed with "0x").
-mode:X - selects startup videomode. Please see above for the format of
- "X".
-
-Boolean options such as "noaccel" or "noypan" are to be given without a
-parameter if sisfb is in-kernel (for example "video=sisfb:noypan). If
-sisfb is a module, these are to be set to 1 (for example "modprobe sisfb
-noypan=1").

-Support is available for filesystems that wish to do automounting support (such
-as kAFS which can be found in fs/afs/). This facility includes allowing
-in-kernel mounts to be performed and mountpoint degradation to be
-requested. The latter can also be requested by userspace.
-
-
-======================
-IN-KERNEL AUTOMOUNTING
-======================
-
-A filesystem can now mount another filesystem on one of its directories by the
-following procedure:
-
- (1) Give the directory a follow_link() operation.
-
- When the directory is accessed, the follow_link op will be called, and
- it will be provided with the location of the mountpoint in the nameidata
- structure (vfsmount and dentry).
-
- (2) Have the follow_link() op do the following steps:
-
- (a) Call do_kern_mount() to call the appropriate filesystem to set up a
- superblock and gain a vfsmount structure representing it.
-
- (b) Copy the nameidata provided as an argument and substitute the dentry
- argument into it the copy.
-
- (c) Call do_add_mount() to install the new vfsmount into the namespace's
- mountpoint tree, thus making it accessible to userspace. Use the
- nameidata set up in (b) as the destination.
-
- If the mountpoint will be automatically expired, then do_add_mount()
- should also be given the location of an expiration list (see further
- down).
-
- (d) Release the path in the nameidata argument and substitute in the new
- vfsmount and its root dentry. The ref counts on these will need
- incrementing.
-
-Then from userspace, you can just do something like:
-
- [root@andromeda root]# mount -t afs \#root.afs. /afs
- [root@andromeda root]# ls /afs
- asd cambridge cambridge.redhat.com grand.central.org
- [root@andromeda root]# ls /afs/cambridge
- afsdoc
- [root@andromeda root]# ls /afs/cambridge/afsdoc/
- ChangeLog html LICENSE pdf RELNOTES-1.2.2
-
-And then if you look in the mountpoint catalogue, you'll see something like:
-
- [root@andromeda root]# cat /proc/mounts
- ...
- #root.afs. /afs afs rw 0 0
- #root.cell. /afs/cambridge.redhat.com afs rw 0 0
- #afsdoc. /afs/cambridge.redhat.com/afsdoc afs rw 0 0
-
-
-===========================
-AUTOMATIC MOUNTPOINT EXPIRY
-===========================
-
-Automatic expiration of mountpoints is easy, provided you've mounted the
-mountpoint to be expired in the automounting procedure outlined above.
-
-To do expiration, you need to follow these steps:
-
- (3) Create at least one list off which the vfsmounts to be expired can be
- hung. Access to this list will be governed by the vfsmount_lock.
-
- (4) In step (2c) above, the call to do_add_mount() should be provided with a
- pointer to this list. It will hang the vfsmount off of it if it succeeds.
-
- (5) When you want mountpoints to be expired, call mark_mounts_for_expiry()
- with a pointer to this list. This will process the list, marking every
- vfsmount thereon for potential expiry on the next call.
-
- If a vfsmount was already flagged for expiry, and if its usage count is 1
- (it's only referenced by its parent vfsmount), then it will be deleted
- from the namespace and thrown away (effectively unmounted).
-
- It may prove simplest to simply call this at regular intervals, using
- some sort of timed event to drive it.
-
-The expiration flag is cleared by calls to mntput. This means that expiration
-will only happen on the second expiration request after the last time the
-mountpoint was accessed.
-
-If a mountpoint is moved, it gets removed from the expiration list. If a bind
-mount is made on an expirable mount, the new vfsmount will not be on the
-expiration list and will not expire.
-
-If a namespace is copied, all mountpoints contained therein will be copied,
-and the copies of those that are on an expiration list will be added to the
-same expiration list.
-
-
-=======================
-USERSPACE DRIVEN EXPIRY
-=======================
-
-As an alternative, it is possible for userspace to request expiry of any
-mountpoint (though some will be rejected - the current process's idea of the
-rootfs for example). It does this by passing the MNT_EXPIRE flag to
-umount(). This flag is considered incompatible with MNT_FORCE and MNT_DETACH.
-
-If the mountpoint in question is in referenced by something other than
-umount() or its parent mountpoint, an EBUSY error will be returned and the
-mountpoint will not be marked for expiration or unmounted.
-
-If the mountpoint was not already marked for expiry at that time, an EAGAIN
-error will be given and it won't be unmounted.
-
-Otherwise if it was already marked and it wasn't referenced, unmounting will
-take place as usual.
-
-Again, the expiration flag is cleared every time anything other than umount()

- High Precision Event Timer Driver for Linux
-
-The High Precision Event Timer (HPET) hardware is the future replacement for the 8254 and Real
-Time Clock (RTC) periodic timer functionality. Each HPET can have up two 32 timers. It is possible
-to configure the first two timers as legacy replacements for 8254 and RTC periodic. A specification
-done by INTEL and Microsoft can be found at http://www.intel.com/labs/platcomp/hpet/hpetspec.htm.
-
-The driver supports detection of HPET driver allocation and initialization of the HPET before the
-driver module_init routine is called. This enables platform code which uses timer 0 or 1 as the
-main timer to intercept HPET initialization. An example of this initialization can be found in
-arch/i386/kernel/time_hpet.c.
-
-The driver provides two APIs which are very similar to the API found in the rtc.c driver.
-There is a user space API and a kernel space API. An example user space program is provided
-below.

-The kernel API has three interfaces exported from the driver:
-
- hpet_register(struct hpet_task *tp, int periodic)
- hpet_unregister(struct hpet_task *tp)
- hpet_control(struct hpet_task *tp, unsigned int cmd, unsigned long arg)
-
-The kernel module using this interface fills in the ht_func and ht_data members of the
-hpet_task structure before calling hpet_register. hpet_control simply vectors to the hpet_ioctl
-routine and has the same commands and respective arguments as the user API. hpet_unregister
-is used to terminate usage of the HPET timer reserved by hpet_register.

-==================
-i2c-parport driver
-==================
-
-2004-07-06, Jean Delvare
-
-This is a unified driver for several i2c-over-parallel-port adapters,
-such as the ones made by Philips, Velleman or ELV. This driver is
-meant as a replacement for the older, individual drivers:
- * i2c-philips-par
- * i2c-elv
- * i2c-velleman
- * video/i2c-parport (NOT the same as this one, dedicated to home brew
- teletext adapters)
-
-It currently supports the following devices:
- * Philips adapter
- * home brew teletext adapter
- * Velleman K8000 adapter
- * ELV adapter
- * Analog Devices evaluation boards (ADM1025, ADM1030, ADM1031, ADM1032)
-
-These devices use different pinout configurations, so you have to tell
-the driver what you have, using the type module parameter. There is no
-way to autodetect the devices. Support for different pinout configurations
-can be easily added when needed.
-
-
-Building your own adapter
--------------------------
-
-If you want to build you own i2c-over-parallel-port adapter, here is
-a sample electronics schema (credits go to Sylvain Munaut):

- the i2c-parport module might be a good safety since data line state
- prior to init may be unknown.
- - This is 5V!
- - Obviously you cannot read SCL (so it's not really standard-compliant).
- Pretty easy to add, just copy the SDA part and use another input pin.
- That would give (ELV compatible pinout):

-Similar (but different) drivers
--------------------------------
-
-This driver is NOT the same as the i2c-pport driver found in the i2c package.
-The i2c-pport driver makes use of modern parallel port features so that
-you don't need additional electronics. It has other restrictions however, and
-was not ported to Linux 2.6 (yet).
-
-This driver is also NOT the same as the i2c-pcf-epp driver found in the
-lm_sensors package. The i2c-pcf-epp driver doesn't use the parallel port
-as an I2C bus directly. Instead, it uses it to control an external I2C bus
-master. That driver was not ported to Linux 2.6 (yet) either.

-Useful links:
-Velleman http://www.velleman.be/

-The project has lead to new libs for the Velleman K8000 and K8005:
- LIBK8000 v1.99.1 and LIBK8005 v0.21
-With these libs, you can control the K8000 interface card and the K8005

----------------------------------------------------------------------------
-1. Driver Introduction:
-
-This is the device driver for the IBM Hypervisor Virtual Console Server,
-"hvcs". The IBM hvcs provides a tty driver interface to allow Linux user
-space applications access to the system consoles of logically partitioned
-operating systems (Linux and AIX) running on the same partitioned Power5
-ppc64 system. Physical hardware consoles per partition are not practical
-on this hardware so system consoles are accessed by this driver using
-firmware interfaces to virtual terminal devices.
-
----------------------------------------------------------------------------
-2. System Requirements:
-
-This device driver was written using 2.6.4 Linux kernel APIs and will only
-build and run on kernels of this version or later.
-
-This driver was written to operate solely on IBM Power5 ppc64 hardware
-though some care was taken to abstract the architecture dependent firmware
-calls from the driver code.
-
-Sysfs must be mounted on the system so that the user can determine which
-major and minor numbers are associated with each vty-server. Directions
-for sysfs mounting are outside the scope of this document.
-
----------------------------------------------------------------------------
-3. Build Options:
-
-The hvcs driver registers itself as a tty driver. The tty layer
-dynamically allocates a block of major and minor numbers in a quantity
-requested by the registering driver. The hvcs driver asks the tty layer
-for 64 of these major/minor numbers by default to use for hvcs device node
-entries.
-
-If the default number of device entries is adequate then this driver can be
-built into the kernel. If not, the default can be over-ridden by inserting
-the driver as a module with insmod parameters.
-
----------------------------------------------------------------------------
-3.1 Built-in:
-
-The following menuconfig example demonstrates selecting to build this
-driver into the kernel.
-
- Device Drivers --->
- Character devices --->
- <*> IBM Hypervisor Virtual Console Server Support
-
-Begin the kernel make process.
-
----------------------------------------------------------------------------
-3.2 Module:
-
-The following menuconfig example demonstrates selecting to build this
-driver as a kernel module.
-
- Device Drivers --->
- Character devices --->
- <M> IBM Hypervisor Virtual Console Server Support
-
-The make process will build the following kernel modules:
-
- hvcs.ko
- hvcserver.ko
-
-To insert the module with the default allocation execute the following
-commands in the order they appear:
-
- insmod hvcserver.ko
- insmod hvcs.ko
-
-The hvcserver module contains architecture specific firmware calls and must
-be inserted first, otherwise the hvcs module will not find some of the
-symbols it expects.
-
-To override the default use an insmod parameter as follows (requesting 4
-tty devices as an example):
-
- insmod hvcs.ko hvcs_parm_num_devs=4
-
-There is a maximum number of dev entries that can be specified on insmod.
-We think that 1024 is currently a decent maximum number of server adapters
-to allow. This can always be changed by modifying the constant in the
-source file before building.
-
-NOTE: The length of time it takes to insmod the driver seems to be related
-to the number of tty interfaces the registering driver requests.
-
-In order to remove the driver module execute the following command:
-
- rmmod hvcs.ko
-
-The recommended method for installing hvcs as a module is to use depmod to
-build a current modules.dep file in /lib/modules/`uname -r` and then
-execute:
-
-modprobe hvcs hvcs_parm_num_devs=4
-
-The modules.dep file indicates that hvcserver.ko needs to be inserted
-before hvcs.ko and modprobe uses this file to smartly insert the modules in
-the proper order.
-
-The following modprobe command is used to remove hvcs and hvcserver in the
-proper order:
-
-modprobe -r hvcs
-
----------------------------------------------------------------------------
-4. Installation:
-
-The tty layer creates sysfs entries which contain the major and minor
-numbers allocated for the hvcs driver. The following snippet of "tree"
-output of the sysfs directory shows where these numbers are presented:
-
- sys/
- |-- *other sysfs base dirs*
- |
- |-- class
- | |-- *other classes of devices*
- | |
- | `-- tty
- | |-- *other tty devices*
- | |
- | |-- hvcs0
- | | `-- dev
- | |-- hvcs1
- | | `-- dev
- | |-- hvcs2
- | | `-- dev
- | |-- hvcs3
- | | `-- dev
- | |
- | |-- *other tty devices*
- |
- |-- *other sysfs base dirs*
-
-For the above examples the following output is a result of cat'ing the
-"dev" entry in the hvcs directory:
-
- Pow5:/sys/class/tty/hvcs0/ # cat dev
- 254:0
-
- Pow5:/sys/class/tty/hvcs1/ # cat dev
- 254:1
-
- Pow5:/sys/class/tty/hvcs2/ # cat dev
- 254:2
-
- Pow5:/sys/class/tty/hvcs3/ # cat dev
- 254:3
-
-The output from reading the "dev" attribute is the char device major and
-minor numbers that the tty layer has allocated for this driver's use. Most
-systems running hvcs will already have the device entries created or udev
-will do it automatically.
-
-Given the example output above, to manually create a /dev/hvcs* node entry
-mknod can be used as follows:
-
- mknod /dev/hvcs0 c 254 0
- mknod /dev/hvcs1 c 254 1
- mknod /dev/hvcs2 c 254 2
- mknod /dev/hvcs3 c 254 3
-
-Using mknod to manually create the device entries makes these device nodes
-persistent. Once created they will exist prior to the driver insmod.
-
-Attempting to connect an application to /dev/hvcs* prior to insertion of
-the hvcs module will result in an error message similar to the following:
-
- "/dev/hvcs*: No such device".
-
-NOTE: Just because there is a device node present doesn't mean that there
-is a vty-server device configured for that node.
-
----------------------------------------------------------------------------
-5. Connection
-
-Since this driver controls devices that provide a tty interface a user can
-interact with the device node entries using any standard tty-interactive
-method (e.g. "cat", "dd", "echo"). The intent of this driver however, is
-to provide real time console interaction with a Linux partition's console,
-which requires the use of applications that provide bi-directional,
-interactive I/O with a tty device.
-
-Applications (e.g. "minicom" and "screen") that act as terminal emulators
-or perform terminal type control sequence conversion on the data being
-passed through them are NOT acceptable for providing interactive console
-I/O. These programs often emulate antiquated terminal types (vt100 and
-ANSI) and expect inbound data to take the form of one of these supported
-terminal types but they either do not convert, or do not _adequately_
-convert, outbound data into the terminal type of the terminal which invoked
-them (though screen makes an attempt and can apparently be configured with
-much termcap wrestling.)
-
-For this reason kermit and cu are two of the recommended applications for
-interacting with a Linux console via an hvcs device. These programs simply
-act as a conduit for data transfer to and from the tty device. They do not
-require inbound data to take the form of a particular terminal type, nor do
-they cook outbound data to a particular terminal type.
-
-In order to ensure proper functioning of console applications one must make
-sure that once connected to a /dev/hvcs console that the console's $TERM
-env variable is set to the exact terminal type of the terminal emulator
-used to launch the interactive I/O application. If one is using xterm and
-kermit to connect to /dev/hvcs0 when the console prompt becomes available
-one should "export TERM=xterm" on the console. This tells ncurses
-applications that are invoked from the console that they should output
-control sequences that xterm can understand.
-
-As a precautionary measure an hvcs user should always "exit" from their
-session before disconnecting an application such as kermit from the device
-node. If this is not done, the next user to connect to the console will
-continue using the previous user's logged in session which includes
-using the $TERM variable that the previous user supplied.
-
----------------------------------------------------------------------------
-6. Disconnection
-
-As a security feature to prevent the delivery of stale data to an
-unintended target the Power5 system firmware disables the fetching of data
-and discards that data when a connection between a vty-server and a vty has
-been severed. As an example, when a vty-server is immediately disconnected
-from a vty following output of data to the vty the vty adapter may not have
-enough time between when it received the data interrupt and when the
-connection was severed to fetch the data from firmware before the fetch is
-disabled by firmware.
-
-When hvcs is being used to serve consoles this behavior is not a huge issue
-because the adapter stays connected for large amounts of time following
-almost all data writes. When hvcs is being used as a tty conduit to tunnel
-data between two partitions [see Q & A below] this is a huge problem
-because the standard Linux behavior when cat'ing or dd'ing data to a device
-is to open the tty, send the data, and then close the tty. If this driver
-manually terminated vty-server connections on tty close this would close
-the vty-server and vty connection before the target vty has had a chance to
-fetch the data.
-
-Additionally, disconnecting a vty-server and vty only on module removal or
-adapter removal is impractical because other vty-servers in other
-partitions may require the usage of the target vty at any time.
-
-Due to this behavioral restriction disconnection of vty-servers from the
-connected vty is a manual procedure using a write to a sysfs attribute
-outlined below, on the other hand the initial vty-server connection to a
-vty is established automatically by this driver. Manual vty-server
-connection is never required.
-
-In order to terminate the connection between a vty-server and vty the
-"vterm_state" sysfs attribute within each vty-server's sysfs entry is used.
-Reading this attribute reveals the current connection state of the
-vty-server adapter. A zero means that the vty-server is not connected to a
-vty. A one indicates that a connection is active.
-
-Writing a '0' (zero) to the vterm_state attribute will disconnect the VTERM
-connection between the vty-server and target vty ONLY if the vterm_state
-previously read '1'. The write directive is ignored if the vterm_state
-read '0' or if any value other than '0' was written to the vterm_state
-attribute. The following example will show the method used for verifying
-the vty-server connection status and disconnecting a vty-server connection.
-
- Pow5:/sys/bus/vio/drivers/hvcs/30000004 # cat vterm_state
- 1
-
- Pow5:/sys/bus/vio/drivers/hvcs/30000004 # echo 0 > vterm_state
-
- Pow5:/sys/bus/vio/drivers/hvcs/30000004 # cat vterm_state
- 0
-
-All vty-server connections are automatically terminated when the device is
-hotplug removed and when the module is removed.
-
----------------------------------------------------------------------------
-7. Configuration
-
-Each vty-server has a sysfs entry in the /sys/devices/vio directory, which
-is symlinked in several other sysfs tree directories, notably under the
-hvcs driver entry, which looks like the following example:
-
- Pow5:/sys/bus/vio/drivers/hvcs # ls
- . .. 30000003 30000004 rescan
-
-By design, firmware notifies the hvcs driver of vty-server lifetimes and
-partner vty removals but not the addition of partner vtys. Since an HMC
-Super Admin can add partner info dynamically we have provided the hvcs
-driver sysfs directory with the "rescan" update attribute which will query
-firmware and update the partner info for all the vty-servers that this
-driver manages. Writing a '1' to the attribute triggers the update. An
-explicit example follows:
-
- Pow5:/sys/bus/vio/drivers/hvcs # echo 1 > rescan
-
-Reading the attribute will indicate a state of '1' or '0'. A one indicates
-that an update is in process. A zero indicates that an update has
-completed or was never executed.
-
-Vty-server entries in this directory are a 32 bit partition unique unit
-address that is created by firmware. An example vty-server sysfs entry
-looks like the following:
-
- Pow5:/sys/bus/vio/drivers/hvcs/30000004 # ls
- . current_vty devspec partner_clcs vterm_state
- .. detach_state name partner_vtys
-
-Each entry is provided, by default with a "name" attribute. Reading the
-"name" attribute will reveal the device type as shown in the following
-example:
-
- Pow5:/sys/bus/vio/drivers/hvcs/30000003 # cat name
- vty-server
-
-Each entry is also provided, by default, with a "devspec" attribute which
-reveals the full device specification when read, as shown in the following
-example:
-
- Pow5:/sys/bus/vio/drivers/hvcs/30000004 # cat devspec
- /vdevice/vty-server@30000004
-
-Each vty-server sysfs dir is provided with two read-only attributes that
-provide lists of easily parsed partner vty data: "partner_vtys" and
-"partner_clcs".
-
- Pow5:/sys/bus/vio/drivers/hvcs/30000004 # cat partner_vtys
- 30000000
- 30000001
- 30000002
- 30000000
- 30000000
-
- Pow5:/sys/bus/vio/drivers/hvcs/30000004 # cat partner_clcs
- U5112.428.103048A-V3-C0
- U5112.428.103048A-V3-C2
- U5112.428.103048A-V3-C3
- U5112.428.103048A-V4-C0
- U5112.428.103048A-V5-C0
-
-Reading partner_vtys returns a list of partner vtys. Vty unit address
-numbering is only per-partition-unique so entries will frequently repeat.
-
-Reading partner_clcs returns a list of "converged location codes" which are
-composed of a system serial number followed by "-V*", where the '*' is the
-target partition number, and "-C*", where the '*' is the slot of the
-adapter. The first vty partner corresponds to the first clc item, the
-second vty partner to the second clc item, etc.
-
-A vty-server can only be connected to a single vty at a time. The entry,
-"current_vty" prints the clc of the currently selected partner vty when
-read.
-
-The current_vty can be changed by writing a valid partner clc to the entry
-as in the following example:
-
- Pow5:/sys/bus/vio/drivers/hvcs/30000004 # echo U5112.428.10304
- 8A-V4-C0 > current_vty
-
-Changing the current_vty when a vty-server is already connected to a vty
-does not affect the current connection. The change takes effect when the
-currently open connection is freed.
-
-Information on the "vterm_state" attribute was covered earlier on the
-chapter entitled "disconnection".

----------------------------------------------------------------------------
-8. Questions & Answers:
-===========================================================================
-Q: What are the security concerns involving hvcs?
-
-A: There are three main security concerns:
-
- 1. The creator of the /dev/hvcs* nodes has the ability to restrict
- the access of the device entries to certain users or groups. It
- may be best to create a special hvcs group privilege for providing
- access to system consoles.
-
- 2. To provide network security when grabbing the console it is
- suggested that the user connect to the console hosting partition
- using a secure method, such as SSH or sit at a hardware console.
-
- 3. Make sure to exit the user session when done with a console or
- the next vty-server connection (which may be from another
- partition) will experience the previously logged in session.
-
----------------------------------------------------------------------------
-Q: How do I multiplex a console that I grab through hvcs so that other
-people can see it:
-
-A: You can use "screen" to directly connect to the /dev/hvcs* device and
-setup a session on your machine with the console group privileges. As
-pointed out earlier by default screen doesn't provide the termcap settings
-for most terminal emulators to provide adequate character conversion from
-term type "screen" to others. This means that curses based programs may
-not display properly in screen sessions.
-
----------------------------------------------------------------------------
-Q: Why are the colors all messed up?
-Q: Why are the control characters acting strange or not working?
-Q: Why is the console output all strange and unintelligible?
-
-A: Please see the preceding section on "Connection" for a discussion of how
-applications can affect the display of character control sequences.
-Additionally, just because you logged into the console using and xterm
-doesn't mean someone else didn't log into the console with the HMC console
-(vt320) before you and leave the session logged in. The best thing to do
-is to export TERM to the terminal type of your terminal emulator when you
-get the console. Additionally make sure to "exit" the console before you
-disconnect from the console. This will ensure that the next user gets
-their own TERM type set when they login.
-
----------------------------------------------------------------------------
-Q: When I try to CONNECT kermit to an hvcs device I get:
-"Sorry, can't open connection: /dev/hvcs*"What is happening?
-
-A: Some other Power5 console mechanism has a connection to the vty and
-isn't giving it up. You can try to force disconnect the consoles from the
-HMC by right clicking on the partition and then selecting "close terminal".
-Otherwise you have to hunt down the people who have console authority. It
-is possible that you already have the console open using another kermit
-session and just forgot about it. Please review the console options for
-Power5 systems to determine the many ways a system console can be held.
-
-OR
-
-A: Another user may not have a connectivity method currently attached to a
-/dev/hvcs device but the vterm_state may reveal that they still have the
-vty-server connection established. They need to free this using the method
-outlined in the section on "Disconnection" in order for others to connect
-to the target vty.
-
-OR
-
-A: The user profile you are using to execute kermit probably doesn't have
-permissions to use the /dev/hvcs* device.
-
-OR
-
-A: You probably haven't inserted the hvcs.ko module yet but the /dev/hvcs*
-entry still exists (on systems without udev).
-
-OR
-
-A: There is not a corresponding vty-server device that maps to an existing
-/dev/hvcs* entry.
-
----------------------------------------------------------------------------
-Q: When I try to CONNECT kermit to an hvcs device I get:
-"Sorry, write access to UUCP lockfile directory denied."
-
-A: The /dev/hvcs* entry you have specified doesn't exist where you said it
-does? Maybe you haven't inserted the module (on systems with udev).
-
----------------------------------------------------------------------------
-Q: If I already have one Linux partition installed can I use hvcs on said
-partition to provide the console for the install of a second Linux
-partition?
-
-A: Yes granted that your are connected to the /dev/hvcs* device using
-kermit or cu or some other program that doesn't provide terminal emulation.
-
----------------------------------------------------------------------------
-Q: Can I connect to more than one partition's console at a time using this
-driver?
-
-A: Yes. Of course this means that there must be more than one vty-server
-configured for this partition and each must point to a disconnected vty.
-
----------------------------------------------------------------------------
-Q: Does the hvcs driver support dynamic (hotplug) addition of devices?
-
-A: Yes, if you have dlpar and hotplug enabled for your system and it has
-been built into the kernel the hvcs drivers is configured to dynamically
-handle additions of new devices and removals of unused devices.
-
----------------------------------------------------------------------------
-Q: Can I use /dev/hvcs* as a conduit to another partition and use a tty
-device on that partition as the other end of the pipe?
-
-A: Yes, on Power5 platforms the hvc_console driver provides a tty interface
-for extra /dev/hvc* devices (where /dev/hvc0 is most likely the console).
-In order to get a tty conduit working between the two partitions the HMC
-Super Admin must create an additional "serial server" for the target
-partition with the HMC gui which will show up as /dev/hvc* when the target
-partition is rebooted.
-
-The HMC Super Admin then creates an additional "serial client" for the
-current partition and points this at the target partition's newly created
-"serial server" adapter (remember the slot). This shows up as an
-additional /dev/hvcs* device.
-
-Now a program on the target system can be configured to read or write to
-/dev/hvc* and another program on the current partition can be configured to
-read or write to /dev/hvcs*. Now you have a tty conduit between two
-partitions.

- - The port is named mpc52xxx, and config options are PPC_MPC52xx. The MGT5100
- is not supported, and I'm not sure anyone is interesting in working on it

- nothing to do with the MPC5200. I also included the 'MPC' for the same
- reason.
- - Of course, I inspired myself from the 2.4 port. If you think I forgot to
- mention you/your company in the copyright of some code, I'll correct it
- ASAP.
- - The codes wants the MBAR to be set at 0xf0000000 by the bootloader. It's
- mapped 1:1 with the MMU. If for whatever reason, you want to change this,
- beware that some code depends on the 0xf0000000 address and other depends
- on the 1:1 mapping.
- - Most of the code assumes that port multiplexing, frequency selection, ...
- has already been done. IMHO this should be done as early as possible, in
- the bootloader. If for whatever reason you can't do it there, do it in the
- platform setup code (if U-Boot) or in the arch/ppc/boot/simple/... (if

-Each CPU has a "base" scheduling domain (struct sched_domain). These are
-accessed via cpu_sched_domain(i) and this_sched_domain() macros. The domain
-hierarchy is built from these base domains via the ->parent pointer. ->parent
-MUST be NULL terminated, and domain structures should be per-CPU as they
-are locklessly updated.
-
-Each scheduling domain spans a number of CPUs (stored in the ->span field).
-A domain's span MUST be a superset of it child's span, and a base domain
-for CPU i MUST span at least i. The top domain for each CPU will generally
-span all CPUs in the system although strictly it doesn't have to, but this
-could lead to a case where some CPUs will never be given tasks to run unless
-the CPUs allowed mask is explicitly set. A sched domain's span means "balance
-process load among these CPUs".
-
-Each scheduling domain must have one or more CPU groups (struct sched_group)
-which are organised as a circular one way linked list from the ->groups
-pointer. The union of cpumasks of these groups MUST be the same as the
-domain's span. The intersection of cpumasks from any two of these groups
-MUST be the empty set. The group pointed to by the ->groups pointer MUST
-contain the CPU to which the domain belongs. Groups may be shared among
-CPUs as they contain read only data after they have been set up.
-
-Balancing within a sched domain occurs between groups. That is, each group
-is treated as one entity. The load of a group is defined as the sum of the
-load of each of its member CPUs, and only when the load of a group becomes
-out of balance are tasks moved between groups.
-
-In kernel/sched.c, rebalance_tick is run periodically on each CPU. This
-function takes its CPU's base sched domain and checks to see if has reached
-its rebalance interval. If so, then it will run load_balance on that domain.
-rebalance_tick then checks the parent sched_domain (if it exists), and the
-parent of the parent and so forth.
-
-*** Implementing sched domains ***
-The "base" domain will "span" the first level of the hierarchy. In the case
-of SMT, you'll span all siblings of the physical CPU, with each group being
-a single virtual CPU.
-
-In SMP, the parent of the base domain will span all physical CPUs in the
-node. Each group being a single physical CPU. Then with NUMA, the parent
-of the SMP domain will span the entire machine, with each group having the
-cpumask of a node. Or, you could do multi-level NUMA or Opteron, for example,
-might have just one domain covering its one NUMA level.
-
-The implementor should read comments in include/linux/sched.h:
-struct sched_domain fields, SD_FLAG_*, SD_*_INIT to get an idea of
-the specifics and what to tune.
-
-Implementors should change the line
-#undef SCHED_DOMAIN_DEBUG
-to
-#define SCHED_DOMAIN_DEBUG
-in kernel/sched.c as this enables an error checking parse of the sched domains
-which should catch most possible errors (described above). It also prints out
-the domain structure in a visual format.

- Sound Blaster Audigy mixer / default DSP code
- ===========================================
-
-This is based on SB-Live-mixer.txt.
-
-The EMU10K2 chips have a DSP part which can be programmed to support
-various ways of sample processing, which is described here.
-(This acticle does not deal with the overall functionality of the
-EMU10K2 chips. See the manuals section for further details.)
-
-The ALSA driver programs this portion of chip by default code
-(can be altered later) which offers the following functionality:
-
-
-1) Digital mixer controls
--------------------------
-
-These controls are built using the DSP instructions. They offer extended
-functionality. Only the default build-in code in the ALSA driver is described
-here. Note that the controls work as attenuators: the maximum value is the
-neutral position leaving the signal unchanged. Note that if the same destination
-is mentioned in multiple controls, the signal is accumulated and can be wrapped
-(set to maximal or minimal value without checking of overflow).
-
-
-Explanation of used abbreviations:
-
-DAC - digital to analog converter
-ADC - analog to digital converter
-I2S - one-way three wire serial bus for digital sound by Philips Semiconductors
- (this standard is used for connecting standalone DAC and ADC converters)
-LFE - low frequency effects (subwoofer signal)
-AC97 - a chip containing an analog mixer, DAC and ADC converters
-IEC958 - S/PDIF
-FX-bus - the EMU10K2 chip has an effect bus containing 64 accumulators.
- Each of the synthesizer voices can feed its output to these accumulators
- and the DSP microcontroller can operate with the resulting sum.

-
-
-3. Overview
-===========
-This driver attempts to support the video streaming capabilities of the devices
-mounting the SONiX SN9C101 or SONiX SN9C102 PC Camera Controllers.
-
-- It's worth to note that SONiX has never collaborated with me during the
-development of this project, despite of several requests for enough detailed
-specifications of the register tables, compression engine and video data format
-of the above chips -
-
-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 the hotplug facility.
-
-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 SN9C10[12] driver can be found at the following URL:
-http://go.lamarinapunto.com/
-
-
-4. 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
-
-
-5. 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 usbcore
- [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
-
-
-6. Module parameters
-====================
-Module parameters are listed below:
--------------------------------------------------------------------------------
-Name: video_nr
-Type: int array (min = 0, max = 32)
-Syntax: <-1|n[,...]>
-Description: Specify V4L2 minor mode number:
- -1 = use next available
- n = use minor number n
- You can specify up to 32 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: debug
-Type: int
-Syntax: <n>
-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 just one device
- is used.
-Default: 2
--------------------------------------------------------------------------------
-
-
-7. Device control through "sysfs"
-=================================
-It is possible to read and write both the SN9C10[12] and the image sensor
-registers by using the "sysfs" filesystem interface.
-
-Every time a supported device is recognized, read-only files named "redblue"
-and "green" are created in the /sys/class/video4linux/videoX directory. You can
-set the red, blue and green channel's gain by writing the desired value to
-them. The value may range from 0 to 15 for each channel; this means that
-"redblue" accepts 8-bit values, where the low 4 bits are reserved for red and
-the others for blue.
-
-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
-SN9C10[12] bridge, while the other two control the sensor chip. "reg" and
-"i2c_reg" hold the values of the current register index where the following
-reading/writing operations are addressed at through "val" and "i2c_val". Their
-use is not intended for end-users, unless you know what you are doing. Note
-that "i2c_reg" and "i2c_val" won't be created if the sensor does not actually
-support the standard I2C protocol. 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 usually is 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
-
-Now let's set the green gain's register of the SN9C10[12] chip to 2:
-
- [root@localhost #] echo 0x11 > reg
- [root@localhost #] echo 2 > val
-
-Note that the SN9C10[12] always returns 0 when some of its registers are read.
-To avoid race conditions, all the I/O accesses to the files are serialized.
-
-
-8. Supported devices
-====================
-- I won't mention any of the names of the companies as well as their products
-here. They have never collaborated with me, 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 SN9C10[12] PC camera controllers:
-
-Vendor ID Product ID
---------- ----------
-0xc45 0x6001
-0xc45 0x6005
-0xc45 0x6009
-0xc45 0x600d
-0xc45 0x6024
-0xc45 0x6025
-0xc45 0x6028
-0xc45 0x6029
-0xc45 0x602a
-0xc45 0x602c
-0xc45 0x8001
-
-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
------ ------------
-PAS106B PixArt Imaging Inc.
-TAS5110C1B Taiwan Advanced Sensor Corporation
-TAS5130D1B Taiwan Advanced Sensor Corporation
-
-If you think your camera is based on the above hardware and is not actually
-listed in the above table, you may try to add the specific USB VendorID and
-ProductID identifiers to the sn9c102_id_table[] in the file "sn9c102_sensor.h";
-then compile, load the module again and look at the kernel output.
-If this works, please send an email to me reporting the kernel messages, so
-that I will add a new entry in the list of supported devices.
-
-Donations of new models for further testing and support would be much
-appreciated. I won't add official support for hardware that I don't actually
-have.
-
-
-9. How to add support for new image sensors
-===========================================
-It should be easy to write code for new sensors by using the small API that I
-have 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, not yet supported image sensors are: PAS202B (VGA),
-HV7131[D|E1] (VGA), MI03 (VGA), OV7620 (VGA).
-
-
-10. Note for V4L2 developers
-============================
-This driver follows the V4L2 API specifications. In particular, it enforces two
-rules:
-
-1) 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.
-
-2) Previously mapped buffer memory must always be unmapped before calling any
-of the "VIDIOC_S_CROP", "VIDIOC_TRY_FMT" and "VIDIOC_S_FMT" ioctl's. In case,
-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 them again before any I/O attempts.
-
-
-11. Contact information
-=======================
-I may be contacted by e-mail at <luca.risolia@studio.unibo.it>.
-
-I can accept GPG/PGP encrypted e-mail. My GPG key ID is 'FCE635A4'.
-My public 1024-bit key should be available at any keyserver; the fingerprint
-is: '88E8 F32F 7244 68BA 3958 5D40 99DA 5D2A FCE6 35A4'.

- IXP4xx provides two methods of accessing PCI memory space:
-
- 1) A direct mapped window from 0x48000000 to 0x4bffffff (64MB).
- To access PCI via this space, we simply ioremap() the BAR
- into the kernel and we can use the standard read[bwl]/write[bwl]
- macros. This is the preffered method due to speed but it
- limits the system to just 64MB of PCI memory. This can be
- problamatic if using video cards and other memory-heavy devices.
-
- 2) If > 64MB of memory space is required, the IXP4xx can be
- configured to use indirect registers to access PCI This allows
- for up to 128MB (0x48000000 to 0x4fffffff) of memory on the bus.
- The disadvantadge of this is that every PCI access requires
- three local register accesses plus a spinlock, but in some
- cases the performance hit is acceptable. In addition, you cannot
- mmap() PCI devices in this case due to the indirect nature
- of the PCI window.
-
- By default, the direct method is used. Choose this option if you
- need to use the indirect method instead. If you don't know
- what you need, leave this option unselected.

- * Detailed Description:
- *
- * This block implements the I2C interface to the slave devices like the
- * Atmel 24C32 EEPROM and the MAX 1619 Sensors device. The I2C Master interface
- * can be controlled by the SCMB block. And the SCMB block kicks in only when
- * using the Ethernet Mode of operation and __not__ the SysAD mode
- *
- * The SCMB controls the two modes: MDIO and the I2C. The MDIO mode is used to
- * communicate with the Quad-PHY from Marvel. The I2C is used to communicate
- * with the I2C slave devices. It seems that the driver does not explicitly
- * deal with the control of SDA and SCL serial lines. So, the driver will set
- * the slave address, drive the command and then the data. The SCMB will then
- * control the two serial lines as required.
- *
- * It seems the documents are very unclear abt this. Hence, I took some time
- * out to write the desciption to have an idea of how the I2C can actually
- * work. Currently, this Linux driver wont be integrated into the generic Linux
- * I2C framework. And finally, the I2C interface is also known as the 2BI
- * interface. 2BI means 2-bit interface referring to SDA and SCL serial lines
- * respectively.

- * inbound write transaction and PCI outbound read transaction can result in a

- * to be used by the API for internal management purposes, including managing
- * the sg list and allocating memory for the sgl descriptors. One page should

- *
- * Interrupt notes:
- * Each sgl descriptor has a copy of the DMA control word which the DMA engine
- * loads in the control register. The control word has a "global" interrupt
- * enable bit for that channel. Interrupts are further qualified by a few bits
- * in the sgl descriptor count register. In order to setup an sgl, we have to
- * know ahead of time whether or not interrupts will be enabled at the completion
- * of the transfers. Thus, enable_dma_interrupt()/disable_dma_interrupt() MUST
- * be called before calling alloc_dma_handle(). If the interrupt mode will never
- * change after powerup, then enable_dma_interrupt()/disable_dma_interrupt()
- * do not have to be called -- interrupts will be enabled or disabled based
- * on how the channel was configured after powerup by the hw_init_dma_channel()
- * function. Each sgl descriptor will be setup to interrupt if an error occurs;
- * however, only the last descriptor will be setup to interrupt. Thus, an
- * interrupt will occur (if interrupts are enabled) only after the complete
- * sgl transfer is done.

- your box. Other bus systems are ISA, EISA, MicroChannel (MCA) or
- VESA. If you have PCI, say Y, otherwise N.

- Enable this option if your platform does not have a CPU cache which

- will see better performance if you can say 'N', because the PCI DMA
- code will not have to flush the CPU's caches. If you have a PCI host
- bridge integrated with your SH CPU, refer carefully to the chip specs
- to see if you can say 'N' here. Otherwise, leave it as 'Y'.

- If you say Y here, you will have some control over the system even
- if the system crashes for example during kernel debugging (e.g., you
- will be able to flush the buffer cache to disk, reboot the system
- immediately or dump some status information). This is accomplished
- by pressing various keys while holding SysRq (Alt+PrintScreen). It
- also works on a serial console (on PC hardware at least), if you
- send a BREAK and then within 5 seconds a command keypress. The
- keys are documented in Documentation/sysrq.txt. Don't say Y unless

- If you say Y here the resulting kernel image will be slightly larger

- to solve problems without frame pointers.

- FIXME : What if usecs_per_tick is moving around too much, e.g. if an adjtime

- we have calibrated the scaling factor? This will result in either a jump at
- the end of a tick period, or a wrap backwards at the start of the next one,
- if the application is reading the time of day often enough. I think we
- ought to do better than this. For this reason, usecs_per_jiffy is left

- *
- * In other cases, such as the interrupt/exception path, we can poke around
- * the sp/fp.
- *
- * Notably, this entire approach is somewhat error prone, and in the event
- * that the previous frame cannot be determined, that's all we can do.
- * Either way, this still leaves us with a more correct backtrace then what

-! Fast SH memcpy
-!
-! by Toshiyasu Morita (tm@netcom.com)
-! hacked by J"orn Rernnecke (joern.rennecke@superh.com) ("o for o-umlaut)
-! SH5 code Copyright 2002 SuperH Ltd.
-!
-! Entry: ARG0: destination pointer
-! ARG1: source pointer
-! ARG2: byte count
-!
-! Exit: RESULT: destination pointer
-! any other registers in the range r0-r7: trashed
-!
-! Notes: Usually one wants to do small reads and write a longword, but
-! unfortunately it is difficult in some cases to concatanate bytes
-! into a longword on the SH, so this does a longword read and small
-! writes.
-!
-! This implementation makes two assumptions about how it is called:
-!
-! 1.: If the byte count is nonzero, the address of the last byte to be
-! copied is unsigned greater than the address of the first byte to
-! be copied. This could be easily swapped for a signed comparison,
-! but the algorithm used needs some comparison.
-!
-! 2.: When there are two or three bytes in the last word of an 11-or-more
-! bytes memory chunk to b copied, the rest of the word can be read
-! without side effects.
-! This could be easily changed by increasing the minumum size of
-! a fast memcpy and the amount subtracted from r7 before L_2l_loop be 2,
-! however, this would cost a few extra cyles on average.
-! For SHmedia, the assumption is that any quadword can be read in its
-! enirety if at least one byte is included in the copy.
-
-/* Imported into Linux kernel by Richard Curnow. This is used to implement the
- __copy_user function in the general case, so it has to be a distinct
- function from intra-kernel memcpy to allow for exception fix-ups in the
- event that the user pointer is bad somewhere in the copy (e.g. due to
- running off the end of the vma).
-
- Note, this algorithm will be slightly wasteful in the case where the source
- and destination pointers are equally aligned, because the stlo/sthi pairs
- could then be merged back into single stores. If there are a lot of cache
- misses, this is probably offset by the stall lengths on the preloads.

- Tight version of memset for the case of just clearing a page. It turns out
- that having the alloco's spaced out slightly due to the increment/branch
- pair causes them to contend less for access to the cache. Similarly,
- keeping the stores apart from the allocos causes less contention. => Do two
- separate loops. Do multiple stores per loop to amortise the
- increment/branch cost a little.
-
- Parameters:
- r2 : source effective address (start of page)

- Always clears 4096 bytes.

- Tight version of mempy for the case of just copying a page.
- Prefetch strategy empirically optimised against RTL simulations
- of SH5-101 cut2 eval chip with Cayman board DDR memory.
-
- Parameters:
- r2 : source effective address (start of page)
- r3 : destination effective address (start of page)
-
- Always copies 4096 bytes.
-
- Points to review.
- * Currently the prefetch is 4 lines ahead and the alloco is 2 lines ahead.
- It seems like the prefetch needs to be at at least 4 lines ahead to get
- the data into the cache in time, and the allocos contend with outstanding
- prefetches for the same cache set, so it's better to have the numbers
- different.

- - tag inspection overhead
- - (especially for small ranges)
- - potential cost of setting up/tearing down page mapping for
- every line that matches the range
- * cost partly independent of range size
-
- 4. walk all the lines in the cache, check the tags, if a match

- innocent victims) by natural eviction
- + no tlb mapping overheads

- - spurious evictions

- for small ranges. The choice between (3), (4) and (5) for large
- ranges and the range size for the large/small boundary need

- * caller-save regiseters that are not part of the restricted save set. Also, it means that
- * code in this file must not make calls to functions elsewhere in the kernel, or else the
- * excepting context will see corruption in its caller-save registers. Plus, the entry.S save
- * area is non-reentrant, so this code has to run with SR.BL==1, i.e. no interrupts taken inside
- * it and panic on any exception.

- * DS1286 Real Time Clock interface for Linux
- *
- * Copyright (C) 1998, 1999, 2000 Ralf Baechle
- *
- * Based on code written by Paul Gortmaker.
- *
- * This driver allows use of the real time clock (built into nearly all
- * computers) from user space. It exports the /dev/rtc interface supporting
- * various ioctl() and also the /proc/rtc pseudo-file for status
- * information.
- *
- * The ioctls can be used to set the interrupt behaviour and generation rate
- * from the RTC via IRQ 8. Then the /dev/rtc interface can be used to make
- * use of these timer interrupts, be they interval or alarm based.
- *
- * The /dev/rtc interface will block on reads until an interrupt has been
- * received. If a RTC interrupt has already happened, it will output an
- * unsigned long and then block. The output value contains the interrupt
- * status in the low byte and the number of interrupts since the last read
- * in the remaining high bytes. The /dev/rtc interface can also be used with
- * the select(2) call.
- *
- * 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 of the License, or (at your
- * option) any later version.

- *
- * Author(s) : Ryan S. Arnold <rsa@us.ibm.com>
- *
- * This is the device driver for the IBM Hypervisor Virtual Console Server,
- * "hvcs". The IBM hvcs provides a tty driver interface to allow Linux
- * user space applications access to the system consoles of logically
- * partitioned operating systems, e.g. Linux, running on the same partitioned
- * Power5 ppc64 system. Physical hardware consoles per partition are not
- * practical on this hardware so system consoles are accessed by this driver
- * using inter-partition firmware interfaces to virtual terminal devices.
- *
- * A vty is known to the HMC as a "virtual serial server adapter". It is a
- * virtual terminal device that is created by firmware upon partition creation
- * to act as a partitioned OS's console device.
- *
- * Firmware dynamically (via hotplug) exposes vty-servers to a running ppc64
- * Linux system upon their creation by the HMC or their exposure during boot.
- * The non-user interactive backend of this driver is implemented as a vio
- * device driver so that it can receive notification of vty-server lifetimes
- * after it registers with the vio bus to handle vty-server probe and remove
- * callbacks.
- *
- * Many vty-servers can be configured to connect to one vty, but a vty can
- * only be actively connected to by a single vty-server, in any manner, at one
- * time. If the HMC is currently hosting the console for a target Linux
- * partition; attempts to open the tty device to the partition's console using
- * the hvcs on any partition will return -EBUSY with every open attempt until
- * the HMC frees the connection between its vty-server and the desired
- * partition's vty device. Conversely, a vty-server may only be connected to
- * a single vty at one time even though it may have several configured vty
- * partner possibilities.
- *
- * Firmware does not provide notification of vty partner changes to this
- * driver. This means that an HMC Super Admin may add or remove partner vtys
- * from a vty-server's partner list but the changes will not be signaled to
- * the vty-server. Firmware only notifies the driver when a vty-server is
- * added or removed from the system. To compensate for this deficiency, this
- * driver implements a sysfs update attribute which provides a method for
- * rescanning partner information upon a user's request.
- *
- * Each vty-server, prior to being exposed to this driver is reference counted
- * using the 2.6 Linux kernel kobject construct. This kobject is also used by
- * the vio bus to provide a vio device sysfs entry that this driver attaches
- * device specific attributes to, including partner information. The vio bus
- * framework also provides a sysfs entry for each vio driver. The hvcs driver
- * provides driver attributes in this entry.
- *
- * For direction on installation and usage of this driver please reference
- * Documentation/powerpc/hvcs.txt.

- * 1.0.0 -> 1.1.0 Added kernel_thread scheduling methodology to driver to
- * replace wait_task constructs.
- *
- * 1.1.0 -> 1.2.0 Moved pi_buff initialization out of arch code into driver code
- * and added locking to share this buffer between hvcs_struct instances. This
- * is because the page_size kmalloc can't be done with a spin_lock held.
- *
- * Also added sysfs attribute to manually disconnect the vty-server from the vty
- * due to stupid firmware behavior when opening the connection then sending data
- * then then quickly closing the connection would cause data loss on the
- * receiving side. This required some reordering of the termination code.
- *
- * Fixed the hangup scenario and fixed memory leaks on module_exit.
- *
- * 1.2.0 -> 1.3.0 Moved from manual kernel thread creation & execution to
- * kthread construct which replaced in-kernel IPC for thread termination with
- * kthread_stop and kthread_should_stop. Explicit wait_queue handling was
- * removed because kthread handles this. Minor bug fix to postpone partner_info
- * clearing on hvcs_close until adapter removal to preserve context data for
- * printk on partner connection free. Added lock to protect hvcs_structs so
- * that hvcs_struct instances aren't added or removed during list traversal.
- * Cleaned up comment style, added spaces after commas, and broke function
- * declaration lines to be under 80 columns.

- * Intel's IXP4xx XScale NPU chipsets (IXP420, 421, 422, 425) do not have
- * an on board I2C controller but provide 16 GPIO pins that are often
- * used to create an I2C bus. This driver provides an i2c_adapter
- * interface that plugs in under algo_bit and drives the GPIO pins
- * as instructed by the alogorithm driver.

- * NOTE: Since different platforms will use different GPIO pins for
- * I2C, this driver uses an IXP4xx-specific platform_data
- * pointer to pass the GPIO numbers to the driver. This
- * allows us to support all the different IXP4xx platforms
- * w/o having to put #ifdefs in this driver.
- *
- * See arch/arm/mach-ixp4xx/ixdp425.c for an example of building a
- * device list and filling in the ixp4xx_i2c_pins data structure
- * that is passed as the platform_data to this driver.

- * The ADM1025 is a sensor chip made by Analog Devices. It reports up to 6
- * voltages (including its own power source) and up to two temperatures
- * (its own plus up to one external one). Voltages are scaled internally
- * (which is not the common way) 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 deg accuracy. Complete
- * datasheet can be obtained from Analog's website at:
- * http://www.analog.com/Analog_Root/productPage/productHome/0,2121,ADM1025,00.html
- *
- * This driver also supports the ADM1025A, which differs from the ADM1025
- * only in that it has "open-drain VID inputs while the ADM1025 has
- * on-chip 100k pull-ups on the VID inputs". It doesn't make any
- * difference for us.
- *
- * This driver also supports the NE1619, a sensor chip made by Philips.
- * That chip is similar to the ADM1025A, with a few differences. The only
- * difference that matters to us is that the NE1619 has only two possible
- * addresses while the ADM1025A has a third one. Complete datasheet can be
- * obtained from Philips's website at:
- * http://www.semiconductors.philips.com/pip/NE1619DS.html
- *
- * Since the ADM1025 was the first chipset supported by this driver, most
- * comments will refer to this chipset, but are actually general and
- * concern all supported chipsets, unless mentioned otherwise.

-/*-----------------------------------------------------------------
- * Region hash
- *
- * The mirror splits itself up into discrete regions. Each
- * region can be in one of three states: clean, dirty,
- * nosync. There is no need to put clean regions in the hash.
- *
- * In addition to being present in the hash table a region _may_
- * be present on one of three lists.
- *
- * clean_regions: Regions on this list have no io pending to
- * them, they are in sync, we are no longer interested in them,
- * they are dull. rh_update_states() will remove them from the
- * hash table.
- *
- * quiesced_regions: These regions have been spun down, ready
- * for recovery. rh_recovery_start() will remove regions from
- * this list and hand them to kmirrord, which will schedule the
- * recovery io with kcopyd.
- *
- * recovered_regions: Regions that kcopyd has successfully
- * recovered. rh_update_states() will now schedule any delayed
- * io, up the recovery_count, and remove the region from the
- * hash.
- *
- * There are 2 locks:
- * A rw spin lock 'hash_lock' protects just the hash table,
- * this is never held in write mode from interrupt context,
- * which I believe means that we only have to disable irqs when
- * doing a write lock.
- *
- * An ordinary spin lock 'region_lock' that protects the three
- * lists in the region_hash, with the 'state', 'list' and
- * 'bhs_delayed' fields of the regions. This is used from irq
- * context, so all other uses will have to suspend local irqs.

- * drivers/mtd/nand.c
- *
- * Overview:
- * This is the generic MTD driver for NAND flash devices. It should be
- * capable of working with almost all NAND chips currently available.
- * Basic support for AG-AND chips is provided.
- *
- * Additional technical information is available on
- * http://www.linux-mtd.infradead.org/tech/nand.html
- *
- * Copyright (C) 2000 Steven J. Hill (sjhill@realitydiluted.com)
- * 2002 Thomas Gleixner (tglx@linutronix.de)
- *
- * 02-08-2004 tglx: support for strange chips, which cannot auto increment
- * pages on read / read_oob
- *
- * 03-17-2004 tglx: Check ready before auto increment check. Simon Bayes
- * pointed this out, as he marked an auto increment capable chip
- * as NOAUTOINCR in the board driver.
- * Make reads over block boundaries work too
- *
- * 04-14-2004 tglx: first working version for 2k page size chips
- *
- * 05-19-2004 tglx: Basic support for Renesas AG-AND chips
- *
- * Credits:
- * David Woodhouse for adding multichip support
- *
- * Aleph One Ltd. and Toby Churchill Ltd. for supporting the
- * rework for 2K page size chips
- *
- * TODO:
- * Enable cached programming for 2k page size chips
- * Check, if mtd->ecctype should be set to MTD_ECC_HW
- * if we have HW ecc support.
- * The AG-AND chips have nice features for speed improvement,
- * which are not supported yet. Read / program 4 pages in one go.

- *
- * Description:
- *
- * When nand_scan_bbt is called, then it tries to find the bad block table
- * depending on the options in the bbt descriptor(s). If a bbt is found
- * then the contents are read and the memory based bbt is created. If a
- * mirrored bbt is selected then the mirror is searched too and the
- * versions are compared. If the mirror has a greater version number
- * than the mirror bbt is used to build the memory based bbt.
- * If the tables are not versioned, then we "or" the bad block information.
- * If one of the bbt's is out of date or does not exist it is (re)created.
- * If no bbt exists at all then the device is scanned for factory marked
- * good / bad blocks and the bad block tables are created.
- *
- * For manufacturer created bbts like the one found on M-SYS DOC devices
- * the bbt is searched and read but never created
- *
- * The autogenerated bad block table is located in the last good blocks
- * of the device. The table is mirrored, so it can be updated eventually.
- * The table is marked in the oob area with an ident pattern and a version
- * number which indicates which of both tables is more up to date.
- *
- * The table uses 2 bits per block
- * 11b: block is good
- * 00b: block is factory marked bad
- * 01b, 10b: block is marked bad due to wear
- *
- * The memory bad block table uses the following scheme:
- * 00b: block is good
- * 01b: block is marked bad due to wear
- * 10b: block is reserved (to protect the bbt area)
- * 11b: block is factory marked bad
- *
- * Multichip devices like DOC store the bad block info per floor.
- *
- * Following assumptions are made:
- * - bbts start at a page boundary, if autolocated on a block boundary
- * - the space neccecary for a bbt in FLASH does not exceed a block boundary
- *

-/* Probe for various non-shared-memory ethercards.
-
- NEx000-clone boards have a Station Address PROM (SAPROM) in the packet
- buffer memory space. NE2000 clones have 0x57,0x57 in bytes 0x0e,0x0f of
- the SAPROM, while other supposed NE2000 clones must be detected by their
- SA prefix.
-
- Reading the SAPROM from a word-wide card with the 8390 set in byte-wide
- mode results in doubled values, which can be detected and compensated for.
-
- The probe is also responsible for initializing the card and filling
- in the 'dev' and 'ei_status' structures.
-
- We use the minimum memory size for some ethercard product lines, iff we can't
- distinguish models. You can increase the packet buffer size by setting
- PACKETBUF_MEMSIZE. Reported Cabletron packet buffer locations are:

-* sym53c500_cs.c Bob Tracy (rct@frus.com)
-*
-* A rewrite of the pcmcia-cs add-on driver for newer (circa 1997)
-* New Media Bus Toaster PCMCIA SCSI cards using the Symbios Logic
-* 53c500 controller: intended for use with 2.6 and later kernels.
-* The pcmcia-cs add-on version of this driver is not supported
-* beyond 2.4. It consisted of three files with history/copyright
-* information as follows:
-*
-* SYM53C500.h
-* Bob Tracy (rct@frus.com)
-* Original by Tom Corner (tcorner@via.at).
-* Adapted from NCR53c406a.h which is Copyrighted (C) 1994
-* Normunds Saumanis (normunds@rx.tech.swh.lv)
-*
-* SYM53C500.c
-* Bob Tracy (rct@frus.com)
-* Original driver by Tom Corner (tcorner@via.at) was adapted
-* from NCR53c406a.c which is Copyrighted (C) 1994, 1995, 1996
-* Normunds Saumanis (normunds@fi.ibm.com)
-*
-* sym53c500.c
-* Bob Tracy (rct@frus.com)
-* Original by Tom Corner (tcorner@via.at) was adapted from a
-* driver for the Qlogic SCSI card written by

- Cleaned up 26/10/2002 by Alan Cox <alan@redhat.com> as part of the 2.5

- - Some layering violations with its pcmcia stub

- are deemed to be part of the source code.

- * Driver for the PSC of the Freescale MPC52xx PSCs configured as UARTs.
- *
- * FIXME According to the usermanual the status bits in the status register
- * are only updated when the peripherals access the FIFO and not when the
- * CPU access them. So since we use this bits to know when we stop writing
- * and reading, they may not be updated in-time and a race condition may
- * exists. But I haven't be able to prove this and I don't care. But if
- * any problem arises, it might worth checking. The TX/RX FIFO Stats
- * registers should be used in addition.
- * Update: Actually, they seem updated ... At least the bits we use.
- *
- *

-/* OCP Usage :
- *
- * This drivers uses the OCP model. To load the serial driver for one of the
- * PSCs, just add this to the core_ocp table :
- *
- * {
- * .vendor = OCP_VENDOR_FREESCALE,
- * .function = OCP_FUNC_PSC_UART,
- * .index = 0,
- * .paddr = MPC52xx_PSC1,
- * .irq = MPC52xx_PSC1_IRQ,
- * .pm = OCP_CPM_NA,
- * },
- *
- * This is for PSC1, replace the paddr and irq according to the PSC you want to
- * use. The driver all necessary registers to place the PSC in uart mode without
- * DCD. However, the pin multiplexing aren't changed and should be set either
- * by the bootloader or in the platform init code.
- * The index field must be equal to the PSC index ( e.g. 0 for PSC1, 1 for PSC2,
- * and so on). So the PSC1 is mapped to /dev/ttyS0, PSC2 to /dev/ttyS1 and so
- * on. But be warned, it's an ABSOLUTE REQUIREMENT ! This is needed mainly for
- * the console code : without this 1:1 mapping, at early boot time, when we are
- * parsing the kernel args console=ttyS?, we wouldn't know wich PSC it will be
- * mapped to because OCP stuff is not yet initialized.

-/* OVERVIEW.
- This is a small interface that allows you to add support for any CCD/CMOS
- image sensors connected to the SN9C10X bridges. The entire API is documented
- below. In the most general case, to support a sensor there are three steps
- you have to follow:
- 1) define the main "sn9c102_sensor" structure by setting the basic fields;
- 2) write a probing function to be called by the core module when the USB
- camera is recognized, then add both the USB ids and the name of that
- function to the two corresponding tables SENSOR_TABLE and ID_TABLE (see
- below);
- 3) implement the methods that you want/need (and fill the rest of the main
- structure accordingly).
- "sn9c102_pas106b.c" is an example of all this stuff. Remember that you do
- NOT need to touch the source code of the core module for the things to work
- properly, unless you find bugs or flaws in it. Finally, do not forget to
- read the V4L2 API for completeness. */

- the hardware we have. The bounds of the source rectangle _must_ be
- multiple of 16 and must use the same coordinate system as indicated
- before; their centers shall align initially.
- If necessary, the sensor chip must be initialized during init() to
- set the bounds of the active sensor window; however, by default, it
- usually covers the largest achievable area (maxwidth x maxheight)
- of pixels, so no particular initialization is needed, if you have
- defined the correct default bounds in the structures.

- * frame buffer driver for Asiliant 69000 chip
- * Copyright (C) 2001-2003 Saito.K & Jeanne
- *
- * from driver/video/chipsfb.c and,
- *
- * drivers/video/asiliantfb.c -- frame buffer device for
- * Asiliant 69030 chip (formerly Intel, formerly Chips & Technologies)
- * Author: apc@agelectronics.co.uk
- * Copyright (C) 2000 AG Electronics
- * Note: the data sheets don't seem to be available from Asiliant.
- * They are available by searching developer.intel.com, but are not otherwise
- * linked to.
- *
- * This driver should be portable with minimal effort to the 69000 display
- * chip, and to the twin-display mode of the 69030.
- * Contains code from Thomas Hhenleitner <th@visuelle-maschinen.de> (thanks)
- *
- * Derived from the CT65550 driver chipsfb.c:
- * Copyright (C) 1998 Paul Mackerras
- * ...which was derived from the Powermac "chips" driver:

- /* HACK:
- The GBE hardware uses a tiled memory to screen mapping. Tiles are
- blocks of 512x128, 256x128 or 128x128 pixels, respectively for 8bit,
- 16bit and 32 bit modes (64 kB). They cover the screen with partial
- tiles on the right and/or bottom of the screen if needed.
- For exemple in 640x480 8 bit mode the mapping is:
-
- <-------- 640 ----->
- <---- 512 ----><128|384 offscreen>
- ^ ^
- | 128 [tile 0] [tile 1]
- | v
- ^
- 4 128 [tile 2] [tile 3]
- 8 v
- 0 ^
- 128 [tile 4] [tile 5]
- | v
- | ^
- v 96 [tile 6] [tile 7]
- 32 offscreen
-
- Tiles have the advantage that they can be allocated individually in
- memory. However, this mapping is not linear at all, which is not
- really convienient. In order to support linear addressing, the GBE
- DMA hardware is fooled into thinking the screen is only one tile
- large and but has a greater height, so that the DMA transfer covers
- the same region.
- Tiles are still allocated as independent chunks of 64KB of
- continuous physical memory and remapped so that the kernel sees the
- framebuffer as a continuous virtual memory. The GBE tile table is
- set up so that each tile references one of these 64k blocks:
-
- GBE -> tile list framebuffer TLB <------------ CPU
- [ tile 0 ] -> [ 64KB ] <- [ 16x 4KB page entries ] ^
- ... ... ... linear virtual FB
- [ tile n ] -> [ 64KB ] <- [ 16x 4KB page entries ] v
-
-
- The GBE hardware is then told that the buffer is 512*tweaked_height,
- with tweaked_height = real_width*real_height/pixels_per_tile.
- Thus the GBE hardware will scan the first tile, filing the first 64k
- covered region of the screen, and then will proceed to the next
- tile, until the whole screen is covered.
-
- Here is what would happen at 640x480 8bit:
-
- normal tiling linear
- ^ 11111111111111112222 11111111111111111111 ^
- 128 11111111111111112222 11111111111111111111 102 lines
- 11111111111111112222 11111111111111111111 v
- V 11111111111111112222 11111111222222222222
- 33333333333333334444 22222222222222222222
- 33333333333333334444 22222222222222222222
- < 512 > < 256 > 102*640+256 = 64k
-
- NOTE: The only mode for which this is not working is 800x600 8bit,
- as 800*600/512 = 937.5 which is not integer and thus causes
- flickering.
- I guess this is not so important as one can use 640x480 8bit or
- 800x600 16bit anyway.

- * IXP4xx provides two methods of accessing PCI memory space:

- *
- * 2) If > 64MB of memory space is required, the IXP4xx can be configured
- * to use indirect registers to access PCI (as we do below for I/O
- * transactions). This allows for up to 128MB (0x48000000 to 0x4fffffff)
- * of memory on the bus. The disadvantadge of this is that every
- * PCI access requires three local register accesses plus a spinlock,

- * you cannot mmap() PCI devices in this case.

- * Also, many kernel routines increase the page count before a critical

- * becomes free and so that we can also use atomic_inc_and_test to atomically
- * detect when we just tried to grab a ref on a page which some other CPU has

- *
- * For the non-reserved pages, page_count(page) denotes a reference count.
- * page_count() == 0 means the page is free.
- * page_count() == 1 means the page is used for exactly one purpose
- * (e.g. a private data page of one process).
- *
- * A page may be used for kmalloc() or anyone else who does a
- * __get_free_page(). In this case the page_count() is at least 1, and
- * all other fields are unused but should be 0 or NULL. The
- * management of this page is the responsibility of the one who uses
- * it.
- *
- * The other pages (we may call them "process pages") are completely
- * managed by the Linux memory manager: I/O, buffers, swapping etc.
- * The following discussion applies only to them.
- *
- * A page may belong to an inode's memory mapping. In this case,
- * page->mapping is the pointer to the inode, and page->index is the
- * file offset of the page, in units of PAGE_CACHE_SIZE.
- *
- * A page contains an opaque `private' member, which belongs to the
- * page's address_space. Usually, this is the address of a circular
- * list of the page's disk buffers.
- *
- * For pages belonging to inodes, the page_count() is the number of
- * attaches, plus 1 if `private' contains something, plus one for
- * the page cache itself.
- *
- * All pages belonging to an inode are in these doubly linked lists:
- * mapping->clean_pages, mapping->dirty_pages and mapping->locked_pages;
- * using the page->list list_head. These fields are also used for
- * freelist managemet (when page_count()==0).
- *
- * There is also a per-mapping radix tree mapping index to the page
- * in memory if present. The tree is rooted at mapping->root.
- *
- * All process pages can do I/O:
- * - inode pages may need to be read from disk,
- * - inode pages which have been modified and are MAP_SHARED may need
- * to be written to disk,
- * - private pages which have been modified may need to be swapped out
- * to swap space and (later) to be read back into memory.

- * Simple NUMA memory policy for the Linux kernel.
- *
- * Copyright 2003,2004 Andi Kleen, SuSE Labs.
- * Subject to the GNU Public License, version 2.
- *
- * NUMA policy allows the user to give hints in which node(s) memory should
- * be allocated.
- *
- * Support four policies per VMA and per process:
- *
- * The VMA policy has priority over the process policy for a page fault.
- *
- * interleave Allocate memory interleaved over a set of nodes,
- * with normal fallback if it fails.
- * For VMA based allocations this interleaves based on the
- * offset into the backing object or offset into the mapping
- * for anonymous memory. For process policy an process counter
- * is used.
- * bind Only allocate memory on a specific set of nodes,
- * no fallback.
- * preferred Try a specific node first before normal fallback.
- * As a special case node -1 here means do the allocation
- * on the local CPU. This is normally identical to default,
- * but useful to set in a VMA when you have a non default
- * process policy.
- * default Allocate on the local node first, or when on a VMA
- * use the process policy. This is what Linux always did
- * in a NUMA aware kernel and still does by, ahem, default.
- *
- * The process policy is applied for most non interrupt memory allocations
- * in that process' context. Interrupts ignore the policies and always
- * try to allocate on the local CPU. The VMA policy is only applied for memory
- * allocations for a VMA in the VM.
- *
- * Currently there are a few corner cases in swapping where the policy
- * is not applied, but the majority should be handled. When process policy
- * is used it is not remembered over swap outs/swap ins.
- *
- * Only the highest zone in the zone hierarchy gets policied. Allocations
- * requesting a lower zone just use default policy. This implies that
- * on systems with highmem kernel lowmem allocation don't get policied.
- * Same with GFP_DMA allocations.
- *
- * For shmfs/tmpfs/hugetlbfs shared memory the policy is shared between
- * all users and remembered even when nobody has memory mapped.
- */

-/* Notebook:
- fix mmap readahead to honour policy and enable policy for any page cache
- object
- statistics for bigpages
- global policy for page cache? currently it uses process policy. Requires
- first item above.
- handle mremap for shared memory (currently ignored for the policy)
- grows down?
- make bind policy root only? It can trigger oom much faster and the
- kernel is not always grateful with that.
- could replace all the switch()es with a mempolicy_ops structure.

- * Freeing function for a buddy system allocator.

- * The concept of a buddy system is to maintain direct-mapped table

- * The bottom level table contains the map for the smallest allocatable
- * units of memory (here, pages), and each level above it describes

- * At a high level, all that happens here is marking the table entry
- * at the bottom level available, and propagating the changes upward
- * as necessary, plus some accounting needed to play nicely with other
- * parts of the VM system.
- * At each level, we keep one bit for each pair of blocks, which
- * is set to 1 iff only one of the pair is allocated. So when we
- * are allocating or freeing one, we can derive the state of the
- * other. That is, if we allocate a small block, and both were
- * free, the remainder of the region must be split into blocks.
- * If a block is freed, and its buddy is also free, then this
- * triggers coalescing into a block of larger size.

- * A clever mix of heap and radix trees forms a radix priority search tree (PST)
- * which is useful for storing intervals, e.g, we can consider a vma as a closed
- * interval of file pages [offset_begin, offset_end], and store all vmas that
- * map a file in a PST. Then, using the PST, we can answer a stabbing query,
- * i.e., selecting a set of stored intervals (vmas) that overlap with (map) a
- * given input interval X (a set of consecutive file pages), in "O(log n + m)"
- * time where 'log n' is the height of the PST, and 'm' is the number of stored
- * intervals (vmas) that overlap (map) with the input interval X (the set of
- * consecutive file pages).
- *
- * In our implementation, we store closed intervals of the form [radix_index,
- * heap_index]. We assume that always radix_index <= heap_index. McCreight's PST
- * is designed for storing intervals with unique radix indices, i.e., each
- * interval have different radix_index. However, this limitation can be easily
- * overcome by using the size, i.e., heap_index - radix_index, as part of the
- * index, so we index the tree using [(radix_index,size), heap_index].
- *
- * When the above-mentioned indexing scheme is used, theoretically, in a 32 bit
- * machine, the maximum height of a PST can be 64. We can use a balanced version
- * of the priority search tree to optimize the tree height, but the balanced
- * tree proposed by McCreight is too complex and memory-hungry for our purpose.
