+This document describes m[g]flash support in linux.
+
+Contents
+ 1. Overview
+ 2. Reserved area configuration
+ 3. Example of mflash platform driver registration
+
+1. Overview
+
+Mflash and gflash are embedded flash drive. The only difference is mflash is
+MCP(Multi Chip Package) device. These two device operate exactly same way.
+So the rest mflash repersents mflash and gflash altogether.
+
+Internally, mflash has nand flash and other hardware logics and supports
+2 different operation (ATA, IO) modes. ATA mode doesn't need any new
+driver and currently works well under standard IDE subsystem. Actually it's
+one chip SSD. IO mode is ATA-like custom mode for the host that doesn't have
+IDE interface.
+
+Followings are brief descriptions about IO mode.
+A. IO mode based on ATA protocol and uses some custom command. (read confirm,
+write confirm)
+B. IO mode uses SRAM bus interface.
+C. IO mode supports 4kB boot area, so host can boot from mflash.
+
+2. Reserved area configuration
+If host boot from mflash, usually needs raw area for boot loader image. All of
+the mflash's block device operation will be taken this value as start offset.
+Note that boot loader's size of reserved area and kernel configuration value
+must be same.
+
+3. Example of mflash platform driver registration
+Working mflash is very straight forward. Adding platform device stuff to board
+configuration file is all. Here is some pseudo example.
+
+static struct mg_drv_data mflash_drv_data = {
+ /* If you want to polling driver set to 1 */
+ .use_polling = 0,
+ /* device attribution */
+ .dev_attr = MG_BOOT_DEV

+

+ /* Base address of mflash */
+ [0] = {
+ .start = 0x08000000,
+ .end = 0x08000000 + SZ_64K - 1,
+ .flags = IORESOURCE_MEM
+ },
+ /* mflash interrupt pin */
+ [1] = {
+ .start = IRQ_GPIO(84),
+ .end = IRQ_GPIO(84),
+ .flags = IORESOURCE_IRQ
+ },
+ /* mflash reset pin */
+ [2] = {
+ .start = 43,
+ .end = 43,
+ .name = MG_RST_PIN,
+ .flags = IORESOURCE_IO
+ },
+ /* mflash reset-out pin
+ * If you use mflash as storage device (i.e. other than MG_BOOT_DEV),
+ * should assign this */

+
+cpuacct controller uses percpu_counter interface to collect user and

+
+- It is theoretically possible to see wrong values for user and system times.
+ This is because percpu_counter_read() on 32bit systems isn't safe
+ against concurrent writes.
+- It is possible to see slightly outdated values for user and system times
+ due to the batch processing nature of percpu_counter.

+Kernel NFS Server Statistics
+============================
+
+This document describes the format and semantics of the statistics
+which the kernel NFS server makes available to userspace. These
+statistics are available in several text form pseudo files, each of
+which is described separately below.
+
+In most cases you don't need to know these formats, as the nfsstat(8)
+program from the nfs-utils distribution provides a helpful command-line
+interface for extracting and printing them.
+
+All the files described here are formatted as a sequence of text lines,
+separated by newline '\n' characters. Lines beginning with a hash
+'#' character are comments intended for humans and should be ignored
+by parsing routines. All other lines contain a sequence of fields
+separated by whitespace.
+
+/proc/fs/nfsd/pool_stats
+------------------------
+
+This file is available in kernels from 2.6.30 onwards, if the
+/proc/fs/nfsd filesystem is mounted (it almost always should be).
+
+The first line is a comment which describes the fields present in
+all the other lines. The other lines present the following data as
+a sequence of unsigned decimal numeric fields. One line is shown
+for each NFS thread pool.
+
+All counters are 64 bits wide and wrap naturally. There is no way
+to zero these counters, instead applications should do their own
+rate conversion.
+
+pool
+ The id number of the NFS thread pool to which this line applies.
+ This number does not change.
+
+ Thread pool ids are a contiguous set of small integers starting
+ at zero. The maximum value depends on the thread pool mode, but
+ currently cannot be larger than the number of CPUs in the system.
+ Note that in the default case there will be a single thread pool
+ which contains all the nfsd threads and all the CPUs in the system,
+ and thus this file will have a single line with a pool id of "0".
+
+packets-arrived
+ Counts how many NFS packets have arrived. More precisely, this
+ is the number of times that the network stack has notified the
+ sunrpc server layer that new data may be available on a transport
+ (e.g. an NFS or UDP socket or an NFS/RDMA endpoint).
+
+ Depending on the NFS workload patterns and various network stack
+ effects (such as Large Receive Offload) which can combine packets
+ on the wire, this may be either more or less than the number
+ of NFS calls received (which statistic is available elsewhere).
+ However this is a more accurate and less workload-dependent measure
+ of how much CPU load is being placed on the sunrpc server layer
+ due to NFS network traffic.
+
+sockets-enqueued
+ Counts how many times an NFS transport is enqueued to wait for
+ an nfsd thread to service it, i.e. no nfsd thread was considered
+ available.
+
+ The circumstance this statistic tracks indicates that there was NFS
+ network-facing work to be done but it couldn't be done immediately,
+ thus introducing a small delay in servicing NFS calls. The ideal
+ rate of change for this counter is zero; significantly non-zero
+ values may indicate a performance limitation.
+
+ This can happen either because there are too few nfsd threads in the
+ thread pool for the NFS workload (the workload is thread-limited),
+ or because the NFS workload needs more CPU time than is available in
+ the thread pool (the workload is CPU-limited). In the former case,
+ configuring more nfsd threads will probably improve the performance
+ of the NFS workload. In the latter case, the sunrpc server layer is
+ already choosing not to wake idle nfsd threads because there are too
+ many nfsd threads which want to run but cannot, so configuring more
+ nfsd threads will make no difference whatsoever. The overloads-avoided
+ statistic (see below) can be used to distinguish these cases.
+
+threads-woken
+ Counts how many times an idle nfsd thread is woken to try to
+ receive some data from an NFS transport.
+
+ This statistic tracks the circumstance where incoming
+ network-facing NFS work is being handled quickly, which is a good
+ thing. The ideal rate of change for this counter will be close
+ to but less than the rate of change of the packets-arrived counter.
+
+overloads-avoided
+ Counts how many times the sunrpc server layer chose not to wake an
+ nfsd thread, despite the presence of idle nfsd threads, because
+ too many nfsd threads had been recently woken but could not get
+ enough CPU time to actually run.
+
+ This statistic counts a circumstance where the sunrpc layer
+ heuristically avoids overloading the CPU scheduler with too many
+ runnable nfsd threads. The ideal rate of change for this counter
+ is zero. Significant non-zero values indicate that the workload
+ is CPU limited. Usually this is associated with heavy CPU usage
+ on all the CPUs in the nfsd thread pool.
+
+ If a sustained large overloads-avoided rate is detected on a pool,
+ the top(1) utility should be used to check for the following
+ pattern of CPU usage on all the CPUs associated with the given
+ nfsd thread pool.
+
+ - %us ~= 0 (as you're *NOT* running applications on your NFS server)
+
+ - %wa ~= 0
+
+ - %id ~= 0
+
+ - %sy + %hi + %si ~= 100
+
+ If this pattern is seen, configuring more nfsd threads will *not*
+ improve the performance of the workload. If this patten is not
+ seen, then something more subtle is wrong.
+
+threads-timedout
+ Counts how many times an nfsd thread triggered an idle timeout,
+ i.e. was not woken to handle any incoming network packets for
+ some time.
+
+ This statistic counts a circumstance where there are more nfsd
+ threads configured than can be used by the NFS workload. This is
+ a clue that the number of nfsd threads can be reduced without
+ affecting performance. Unfortunately, it's only a clue and not
+ a strong indication, for a couple of reasons:
+
+ - Currently the rate at which the counter is incremented is quite
+ slow; the idle timeout is 60 minutes. Unless the NFS workload
+ remains constant for hours at a time, this counter is unlikely
+ to be providing information that is still useful.
+
+ - It is usually a wise policy to provide some slack,
+ i.e. configure a few more nfsds than are currently needed,
+ to allow for future spikes in load.
+
+
+Note that incoming packets on NFS transports will be dealt with in
+one of three ways. An nfsd thread can be woken (threads-woken counts
+this case), or the transport can be enqueued for later attention
+(sockets-enqueued counts this case), or the packet can be temporarily
+deferred because the transport is currently being used by an nfsd
+thread. This last case is not very interesting and is not explicitly
+counted, but can be inferred from the other counters thus:
+
+packets-deferred = packets-arrived - ( sockets-enqueued + threads-woken )
+
+
+More
+----
+Descriptions of the other statistics file should go here.

+NFSv4.1 Server Implementation
+
+Server support for minorversion 1 can be controlled using the
+/proc/fs/nfsd/versions control file. The string output returned
+by reading this file will contain either "+4.1" or "-4.1"
+correspondingly.
+
+Currently, server support for minorversion 1 is disabled by default.
+It can be enabled at run time by writing the string "+4.1" to
+the /proc/fs/nfsd/versions control file. Note that to write this
+control file, the nfsd service must be taken down. Use your user-mode
+nfs-utils to set this up; see rpc.nfsd(8)
+
+The NFSv4 minorversion 1 (NFSv4.1) implementation in nfsd is based
+on the latest NFSv4.1 Internet Draft:
+http://tools.ietf.org/html/draft-ietf-nfsv4-minorversion1-29
+
+From the many new features in NFSv4.1 the current implementation
+focuses on the mandatory-to-implement NFSv4.1 Sessions, providing
+"exactly once" semantics and better control and throttling of the
+resources allocated for each client.
+
+Other NFSv4.1 features, Parallel NFS operations in particular,
+are still under development out of tree.
+See http://wiki.linux-nfs.org/wiki/index.php/PNFS_prototype_design
+for more information.
+
+The table below, taken from the NFSv4.1 document, lists
+the operations that are mandatory to implement (REQ), optional
+(OPT), and NFSv4.0 operations that are required not to implement (MNI)
+in minor version 1. The first column indicates the operations that
+are not supported yet by the linux server implementation.
+
+The OPTIONAL features identified and their abbreviations are as follows:
+ pNFS Parallel NFS
+ FDELG File Delegations
+ DDELG Directory Delegations
+
+The following abbreviations indicate the linux server implementation status.
+ I Implemented NFSv4.1 operations.
+ NS Not Supported.
+ NS* unimplemented optional feature.
+ P pNFS features implemented out of tree.

+NILFS2
+------
+
+NILFS2 is a log-structured file system (LFS) supporting continuous
+snapshotting. In addition to versioning capability of the entire file
+system, users can even restore files mistakenly overwritten or
+destroyed just a few seconds ago. Since NILFS2 can keep consistency
+like conventional LFS, it achieves quick recovery after system
+crashes.
+
+NILFS2 creates a number of checkpoints every few seconds or per
+synchronous write basis (unless there is no change). Users can select
+significant versions among continuously created checkpoints, and can
+change them into snapshots which will be preserved until they are
+changed back to checkpoints.
+
+There is no limit on the number of snapshots until the volume gets
+full. Each snapshot is mountable as a read-only file system
+concurrently with its writable mount, and this feature is convenient
+for online backup.
+
+The userland tools are included in nilfs-utils package, which is
+available from the following download page. At least "mkfs.nilfs2",
+"mount.nilfs2", "umount.nilfs2", and "nilfs_cleanerd" (so called
+cleaner or garbage collector) are required. Details on the tools are
+described in the man pages included in the package.
+
+Project web page: http://www.nilfs.org/en/
+Download page: http://www.nilfs.org/en/download.html
+Git tree web page: http://www.nilfs.org/git/
+NILFS mailing lists: http://www.nilfs.org/mailman/listinfo/users
+
+Caveats
+=======
+
+Features which NILFS2 does not support yet:
+
+ - atime
+ - extended attributes
+ - POSIX ACLs
+ - quotas
+ - writable snapshots
+ - remote backup (CDP)
+ - data integrity
+ - defragmentation
+
+Mount options
+=============
+
+NILFS2 supports the following mount options:
+(*) == default
+
+barrier=on(*) This enables/disables barriers. barrier=off disables
+ it, barrier=on enables it.
+errors=continue(*) Keep going on a filesystem error.
+errors=remount-ro Remount the filesystem read-only on an error.
+errors=panic Panic and halt the machine if an error occurs.
+cp=n Specify the checkpoint-number of the snapshot to be
+ mounted. Checkpoints and snapshots are listed by lscp
+ user command. Only the checkpoints marked as snapshot
+ are mountable with this option. Snapshot is read-only,
+ so a read-only mount option must be specified together.
+order=relaxed(*) Apply relaxed order semantics that allows modified data
+ blocks to be written to disk without making a
+ checkpoint if no metadata update is going. This mode
+ is equivalent to the ordered data mode of the ext3
+ filesystem except for the updates on data blocks still
+ conserve atomicity. This will improve synchronous
+ write performance for overwriting.
+order=strict Apply strict in-order semantics that preserves sequence
+ of all file operations including overwriting of data
+ blocks. That means, it is guaranteed that no
+ overtaking of events occurs in the recovered file
+ system after a crash.
+
+NILFS2 usage
+============
+
+To use nilfs2 as a local file system, simply:
+
+ # mkfs -t nilfs2 /dev/block_device
+ # mount -t nilfs2 /dev/block_device /dir
+
+This will also invoke the cleaner through the mount helper program
+(mount.nilfs2).
+
+Checkpoints and snapshots are managed by the following commands.
+Their manpages are included in the nilfs-utils package above.
+
+ lscp list checkpoints or snapshots.
+ mkcp make a checkpoint or a snapshot.
+ chcp change an existing checkpoint to a snapshot or vice versa.
+ rmcp invalidate specified checkpoint(s).
+
+To mount a snapshot,
+
+ # mount -t nilfs2 -r -o cp=<cno> /dev/block_device /snap_dir
+
+where <cno> is the checkpoint number of the snapshot.
+
+To unmount the NILFS2 mount point or snapshot, simply:
+
+ # umount /dir
+
+Then, the cleaner daemon is automatically shut down by the umount
+helper program (umount.nilfs2).
+
+Disk format
+===========
+
+A nilfs2 volume is equally divided into a number of segments except
+for the super block (SB) and segment #0. A segment is the container
+of logs. Each log is composed of summary information blocks, payload
+blocks, and an optional super root block (SR):
+
+ ______________________________________________________
+ | |SB| | Segment | Segment | Segment | ... | Segment | |
+ |_|__|_|____0____|____1____|____2____|_____|____N____|_|
+ 0 +1K +4K +8M +16M +24M +(8MB x N)
+ . . (Typical offsets for 4KB-block)
+ . .
+ .______________________.
+ | log | log |... | log |
+ |__1__|__2__|____|__m__|
+ . .
+ . .
+ . .
+ .______________________________.
+ | Summary | Payload blocks |SR|
+ |_blocks__|_________________|__|
+
+The payload blocks are organized per file, and each file consists of
+data blocks and B-tree node blocks:
+
+ |<--- File-A --->|<--- File-B --->|
+ _______________________________________________________________
+ | Data blocks | B-tree blocks | Data blocks | B-tree blocks | ...
+ _|_____________|_______________|_____________|_______________|_
+
+
+Since only the modified blocks are written in the log, it may have
+files without data blocks or B-tree node blocks.
+
+The organization of the blocks is recorded in the summary information
+blocks, which contains a header structure (nilfs_segment_summary), per
+file structures (nilfs_finfo), and per block structures (nilfs_binfo):
+
+ _________________________________________________________________________
+ | Summary | finfo | binfo | ... | binfo | finfo | binfo | ... | binfo |...
+ |_blocks__|___A___|_(A,1)_|_____|(A,Na)_|___B___|_(B,1)_|_____|(B,Nb)_|___
+
+
+The logs include regular files, directory files, symbolic link files
+and several meta data files. The mata data files are the files used
+to maintain file system meta data. The current version of NILFS2 uses
+the following meta data files:
+
+ 1) Inode file (ifile) -- Stores on-disk inodes
+ 2) Checkpoint file (cpfile) -- Stores checkpoints
+ 3) Segment usage file (sufile) -- Stores allocation state of segments
+ 4) Data address translation file -- Maps virtual block numbers to usual
+ (DAT) block numbers. This file serves to
+ make on-disk blocks relocatable.
+
+The following figure shows a typical organization of the logs:
+
+ _________________________________________________________________________
+ | Summary | regular file | file | ... | ifile | cpfile | sufile | DAT |SR|
+ |_blocks__|_or_directory_|_______|_____|_______|________|________|_____|__|
+
+
+To stride over segment boundaries, this sequence of files may be split
+into multiple logs. The sequence of logs that should be treated as
+logically one log, is delimited with flags marked in the segment
+summary. The recovery code of nilfs2 looks this boundary information
+to ensure atomicity of updates.
+
+The super root block is inserted for every checkpoints. It includes
+three special inodes, inodes for the DAT, cpfile, and sufile. Inodes
+of regular files, directories, symlinks and other special files, are
+included in the ifile. The inode of ifile itself is included in the
+corresponding checkpoint entry in the cpfile. Thus, the hierarchy
+among NILFS2 files can be depicted as follows:
+
+ Super block (SB)
+ |
+ v
+ Super root block (the latest cno=xx)
+ |-- DAT
+ |-- sufile
+ `-- cpfile
+ |-- ifile (cno=c1)
+ |-- ifile (cno=c2) ---- file (ino=i1)
+ : : |-- file (ino=i2)
+ `-- ifile (cno=xx) |-- file (ino=i3)
+ : :
+ `-- file (ino=yy)
+ ( regular file, directory, or symlink )
+
+For detail on the format of each file, please see include/linux/nilfs2_fs.h.

+Kernel driver g760a
+===================
+
+Supported chips:
+ * Global Mixed-mode Technology Inc. G760A
+ Prefix: 'g760a'
+ Datasheet: Publicly available at the GMT website
+ http://www.gmt.com.tw/datasheet/g760a.pdf
+
+Author: Herbert Valerio Riedel <hvr@gnu.org>
+
+Description
+-----------
+
+The GMT G760A Fan Speed PWM Controller is connected directly to a fan
+and performs closed-loop control of the fan speed.
+
+The fan speed is programmed by setting the period via 'pwm1' of two
+consecutive speed pulses. The period is defined in terms of clock
+cycle counts of an assumed 32kHz clock source.
+
+Setting a period of 0 stops the fan; setting the period to 255 sets
+fan to maximum speed.
+
+The measured fan rotation speed returned via 'fan1_input' is derived
+from the measured speed pulse period by assuming again a 32kHz clock
+source and a 2 pulse-per-revolution fan.

+Datagram vs Connected modes
+
+ The IPoIB driver supports two modes of operation: datagram and
+ connected. The mode is set and read through an interface's
+ /sys/class/net/<intf name>/mode file.
+
+ In datagram mode, the IB UD (Unreliable Datagram) transport is used
+ and so the interface MTU has is equal to the IB L2 MTU minus the
+ IPoIB encapsulation header (4 bytes). For example, in a typical IB
+ fabric with a 2K MTU, the IPoIB MTU will be 2048 - 4 = 2044 bytes.
+
+ In connected mode, the IB RC (Reliable Connected) transport is used.
+ Connected mode is to takes advantage of the connected nature of the
+ IB transport and allows an MTU up to the maximal IP packet size of
+ 64K, which reduces the number of IP packets needed for handling
+ large UDP datagrams, TCP segments, etc and increases the performance
+ for large messages.
+
+ In connected mode, the interface's UD QP is still used for multicast
+ and communication with peers that don't support connected mode. In
+ this case, RX emulation of ICMP PMTU packets is used to cause the
+ networking stack to use the smaller UD MTU for these neighbours.
+
+Stateless offloads
+
+ If the IB HW supports IPoIB stateless offloads, IPoIB advertises
+ TCP/IP checksum and/or Large Send (LSO) offloading capability to the
+ network stack.
+
+ Large Receive (LRO) offloading is also implemented and may be turned
+ on/off using ethtool calls. Currently LRO is supported only for
+ checksum offload capable devices.
+
+ Stateless offloads are supported only in datagram mode.
+
+Interrupt moderation
+
+ If the underlying IB device supports CQ event moderation, one can
+ use ethtool to set interrupt mitigation parameters and thus reduce
+ the overhead incurred by handling interrupts. The main code path of
+ IPoIB doesn't use events for TX completion signaling so only RX
+ moderation is supported.

+rotary-encoder - a generic driver for GPIO connected devices
+Daniel Mack <daniel@caiaq.de>, Feb 2009
+
+0. Function
+-----------
+
+Rotary encoders are devices which are connected to the CPU or other
+peripherals with two wires. The outputs are phase-shifted by 90 degrees
+and by triggering on falling and rising edges, the turn direction can
+be determined.
+
+The phase diagram of these two outputs look like this:
+
+ _____ _____ _____
+ | | | | | |
+ Channel A ____| |_____| |_____| |____
+
+ : : : : : : : : : : : :
+ __ _____ _____ _____

+ one step
+
+
+For more information, please see
+ http://en.wikipedia.org/wiki/Rotary_encoder
+
+
+1. Events / state machine
+-------------------------
+
+a) Rising edge on channel A, channel B in low state
+ This state is used to recognize a clockwise turn
+
+b) Rising edge on channel B, channel A in high state
+ When entering this state, the encoder is put into 'armed' state,
+ meaning that there it has seen half the way of a one-step transition.
+
+c) Falling edge on channel A, channel B in high state
+ This state is used to recognize a counter-clockwise turn
+
+d) Falling edge on channel B, channel A in low state
+ Parking position. If the encoder enters this state, a full transition
+ should have happend, unless it flipped back on half the way. The
+ 'armed' state tells us about that.
+
+2. Platform requirements
+------------------------
+
+As there is no hardware dependent call in this driver, the platform it is
+used with must support gpiolib. Another requirement is that IRQs must be
+able to fire on both edges.
+
+
+3. Board integration
+--------------------
+
+To use this driver in your system, register a platform_device with the
+name 'rotary-encoder' and associate the IRQs and some specific platform
+data with it.
+
+struct rotary_encoder_platform_data is declared in
+include/linux/rotary-encoder.h and needs to be filled with the number of
+steps the encoder has and can carry information about externally inverted
+signals (because of used invertig buffer or other reasons).
+
+Because GPIO to IRQ mapping is platform specific, this information must
+be given in seperately to the driver. See the example below.

2.1. Modules
-------
- To get the device working, you have to load the proper kernel module. You
- can do this using
- modprobe modulename
- where modulename is ser_gigaset (M101), usb_gigaset (M105), or
- bas_gigaset (direct USB connection to the base).
+ For the devices to work, the proper kernel modules have to be loaded.

+ device (base, M105) or when the line discipline is attached (M101). It
+ can also be triggered manually using the modprobe(8) command, for example
+ for troubleshooting or to pass module parameters.
The module ser_gigaset provides a serial line discipline N_GIGASET_M101
- which drives the device through the regular serial line driver. To use it,
- run the Gigaset M101 daemon "gigasetm101d" (also available from
- http://sourceforge.net/projects/gigaset307x/) with the device file of the
- RS232 port to the M101 as an argument, for example:
- gigasetm101d /dev/ttyS1
- This will open the device file, set its line discipline to N_GIGASET_M101,
- and then sleep in the background, keeping the device open so that the
- line discipline remains active. To deactivate it, kill the daemon, for
- example with
- killall gigasetm101d
- before disconnecting the device.

+=== 7 Kbuild syntax for exported headers
+
+The kernel include a set of headers that is exported to userspace.
+Many headers can be exported as-is but other headers requires a
+minimal pre-processing before they are ready for user-space.
+The pre-processing does:
+- drop kernel specific annotations
+- drop include of compiler.h
+- drop all sections that is kernel internat (guarded by ifdef __KERNEL__)
+
+Each relevant directory contain a file name "Kbuild" which specify the
+headers to be exported.
+See subsequent chapter for the syntax of the Kbuild file.
+
+ --- 7.1 header-y
+
+ header-y specify header files to be exported.
+
+ Example:
+ #include/linux/Kbuild
+ header-y += usb/
+ header-y += aio_abi.h
+
+ The convention is to list one file per line and
+ preferably in alphabetic order.
+
+ header-y also specify which subdirectories to visit.
+ A subdirectory is identified by a trailing '/' which
+ can be seen in the example above for the usb subdirectory.
+
+ Subdirectories are visited before their parent directories.
+
+ --- 7.2 objhdr-y
+
+ objhdr-y specifies generated files to be exported.
+ Generated files are special as they need to be looked
+ up in another directory when doing 'make O=...' builds.
+
+ Example:
+ #include/linux/Kbuild
+ objhdr-y += version.h
+
+ --- 7.3 destination-y
+
+ When an architecture have a set of exported headers that needs to be
+ exported to a different directory destination-y is used.
+ destination-y specify the destination directory for all exported
+ headers in the file where it is present.
+
+ Example:
+ #arch/xtensa/platforms/s6105/include/platform/Kbuild
+ destination-y := include/linux
+
+ In the example above all exported headers in the Kbuild file
+ will be located in the directory "include/linux" when exported.

+ASoC jack detection
+===================
+
+ALSA has a standard API for representing physical jacks to user space,
+the kernel side of which can be seen in include/sound/jack.h. ASoC
+provides a version of this API adding two additional features:
+
+ - It allows more than one jack detection method to work together on one
+ user visible jack. In embedded systems it is common for multiple
+ to be present on a single jack but handled by separate bits of
+ hardware.
+
+ - Integration with DAPM, allowing DAPM endpoints to be updated
+ automatically based on the detected jack status (eg, turning off the
+ headphone outputs if no headphones are present).
+
+This is done by splitting the jacks up into three things working
+together: the jack itself represented by a struct snd_soc_jack, sets of
+snd_soc_jack_pins representing DAPM endpoints to update and blocks of
+code providing jack reporting mechanisms.
+
+For example, a system may have a stereo headset jack with two reporting
+mechanisms, one for the headphone and one for the microphone. Some
+systems won't be able to use their speaker output while a headphone is
+connected and so will want to make sure to update both speaker and
+headphone when the headphone jack status changes.
+
+The jack - struct snd_soc_jack
+==============================
+
+This represents a physical jack on the system and is what is visible to
+user space. The jack itself is completely passive, it is set up by the
+machine driver and updated by jack detection methods.
+
+Jacks are created by the machine driver calling snd_soc_jack_new().
+
+snd_soc_jack_pin
+================
+
+These represent a DAPM pin to update depending on some of the status
+bits supported by the jack. Each snd_soc_jack has zero or more of these
+which are updated automatically. They are created by the machine driver
+and associated with the jack using snd_soc_jack_add_pins(). The status
+of the endpoint may configured to be the opposite of the jack status if
+required (eg, enabling a built in microphone if a microphone is not
+connected via a jack).
+
+Jack detection methods
+======================
+
+Actual jack detection is done by code which is able to monitor some
+input to the system and update a jack by calling snd_soc_jack_report(),
+specifying a subset of bits to update. The jack detection code should
+be set up by the machine driver, taking configuration for the jack to
+update and the set of things to report when the jack is connected.
+
+Often this is done based on the status of a GPIO - a handler for this is
+provided by the snd_soc_jack_add_gpio() function. Other methods are
+also available, for example integrated into CODECs. One example of
+CODEC integrated jack detection can be see in the WM8350 driver.
+
+Each jack may have multiple reporting mechanisms, though it will need at
+least one to be useful.
+
+Machine drivers
+===============
+
+These are all hooked together by the machine driver depending on the
+system hardware. The machine driver will set up the snd_soc_jack and
+the list of pins to update then set up one or more jack detection
+mechanisms to update that jack based on their current status.

+
+Constraints
+-----------
+ a) Image size for YUV422P format
+ All YUV422P images are enforced to have width x height % 16 = 0.
+ This is due to DMA constraints, which transfers only planes of 8 byte
+ multiples.
+
+
+Global video workflow
+---------------------
+ a) QCI stopped
+ Initialy, the QCI interface is stopped.
+ When a buffer is queued (pxa_videobuf_ops->buf_queue), the QCI starts.
+
+ b) QCI started
+ More buffers can be queued while the QCI is started without halting the
+ capture. The new buffers are "appended" at the tail of the DMA chain, and
+ smoothly captured one frame after the other.
+
+ Once a buffer is filled in the QCI interface, it is marked as "DONE" and
+ removed from the active buffers list. It can be then requeud or dequeued by
+ userland application.
+
+ Once the last buffer is filled in, the QCI interface stops.
+
+
+DMA usage
+---------
+ a) DMA flow
+ - first buffer queued for capture
+ Once a first buffer is queued for capture, the QCI is started, but data
+ transfer is not started. On "End Of Frame" interrupt, the irq handler
+ starts the DMA chain.
+ - capture of one videobuffer
+ The DMA chain starts transfering data into videobuffer RAM pages.
+ When all pages are transfered, the DMA irq is raised on "ENDINTR" status
+ - finishing one videobuffer
+ The DMA irq handler marks the videobuffer as "done", and removes it from
+ the active running queue
+ Meanwhile, the next videobuffer (if there is one), is transfered by DMA
+ - finishing the last videobuffer
+ On the DMA irq of the last videobuffer, the QCI is stopped.
+
+ b) DMA prepared buffer will have this structure
+
+ +------------+-----+---------------+-----------------+
+ | desc-sg[0] | ... | desc-sg[last] | finisher/linker |
+ +------------+-----+---------------+-----------------+
+
+ This structure is pointed by dma->sg_cpu.
+ The descriptors are used as follows :
+ - desc-sg[i]: i-th descriptor, transfering the i-th sg
+ element to the video buffer scatter gather
+ - finisher: has ddadr=DADDR_STOP, dcmd=ENDIRQEN
+ - linker: has ddadr= desc-sg[0] of next video buffer, dcmd=0
+
+ For the next schema, let's assume d0=desc-sg[0] .. dN=desc-sg[N],
+ "f" stands for finisher and "l" for linker.
+ A typical running chain is :
+
+ Videobuffer 1 Videobuffer 2
+ +---------+----+---+ +----+----+----+---+
+ | d0 | .. | dN | l | | d0 | .. | dN | f |
+ +---------+----+-|-+ ^----+----+----+---+
+ | |
+ +----+
+
+ After the chaining is finished, the chain looks like :
+
+ Videobuffer 1 Videobuffer 2 Videobuffer 3
+ +---------+----+---+ +----+----+----+---+ +----+----+----+---+
+ | d0 | .. | dN | l | | d0 | .. | dN | l | | d0 | .. | dN | f |
+ +---------+----+-|-+ ^----+----+----+-|-+ ^----+----+----+---+
+ | | | |
+ +----+ +----+
+ new_link
+
+ c) DMA hot chaining timeslice issue
+
+ As DMA chaining is done while DMA _is_ running, the linking may be done
+ while the DMA jumps from one Videobuffer to another. On the schema, that
+ would be a problem if the following sequence is encountered :
+
+ - DMA chain is Videobuffer1 + Videobuffer2
+ - pxa_videobuf_queue() is called to queue Videobuffer3
+ - DMA controller finishes Videobuffer2, and DMA stops
+ =>
+ Videobuffer 1 Videobuffer 2
+ +---------+----+---+ +----+----+----+---+
+ | d0 | .. | dN | l | | d0 | .. | dN | f |
+ +---------+----+-|-+ ^----+----+----+-^-+
+ | | |
+ +----+ +-- DMA DDADR loads DDADR_STOP
+
+ - pxa_dma_add_tail_buf() is called, the Videobuffer2 "finisher" is
+ replaced by a "linker" to Videobuffer3 (creation of new_link)
+ - pxa_videobuf_queue() finishes
+ - the DMA irq handler is called, which terminates Videobuffer2
+ - Videobuffer3 capture is not scheduled on DMA chain (as it stopped !!!)
+
+ Videobuffer 1 Videobuffer 2 Videobuffer 3
+ +---------+----+---+ +----+----+----+---+ +----+----+----+---+
+ | d0 | .. | dN | l | | d0 | .. | dN | l | | d0 | .. | dN | f |
+ +---------+----+-|-+ ^----+----+----+-|-+ ^----+----+----+---+
+ | | | |
+ +----+ +----+
+ new_link
+ DMA DDADR still is DDADR_STOP
+
+ - pxa_camera_check_link_miss() is called
+ This checks if the DMA is finished and a buffer is still on the
+ pcdev->capture list. If that's the case, the capture will be restarted,
+ and Videobuffer3 is scheduled on DMA chain.
+ - the DMA irq handler finishes
+
+ Note: if DMA stops just after pxa_camera_check_link_miss() reads DDADR()
+ value, we have the guarantee that the DMA irq handler will be called back
+ when the DMA will finish the buffer, and pxa_camera_check_link_miss() will
+ be called again, to reschedule Videobuffer3.
