iii. Plugging the queue to batch requests in anticipation of opportunities for
merge/sort optimizations
This is just the same as in 2.4 so far, though per-device unplugging
support is anticipated for 2.5. Also with a priority-based i/o scheduler,
such decisions could be based on request priorities.
Plugging is an approach that the current i/o scheduling algorithm resorts to so
that it collects up enough requests in the queue to be able to take
advantage of the sorting/merging logic in the elevator. If the
queue is empty when a request comes in, then it plugs the request queue

the requests. This provides an opportunity to merge/sort the requests before
passing them down to the device. There are various conditions when the queue is
unplugged (to open up the flow again), either through a scheduled task or
could be on demand. For example wait_on_buffer sets the unplugging going

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,

.dev_attr = MG_BOOT_DEV
};

cpuacct.stat file lists a few statistics which further divide the
CPU time obtained by the cgroup into user and system times. Currently
the following statistics are supported:
user: Time spent by tasks of the cgroup in user mode.
system: Time spent by tasks of the cgroup in kernel mode.
user and system are in USER_HZ unit.
cpuacct controller uses percpu_counter interface to collect user and
system times. This has two side effects:
- 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.

be probed later if another device registers. (Which is OK, since
this interface is only for use with non-hotpluggable devices.)
Early Platform Devices and Drivers
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The early platform interfaces provide platform data to platform device
drivers early on during the system boot. The code is built on top of the
early_param() command line parsing and can be executed very early on.
Example: "earlyprintk" class early serial console in 6 steps
1. Registering early platform device data
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The architecture code registers platform device data using the function
early_platform_add_devices(). In the case of early serial console this
should be hardware configuration for the serial port. Devices registered
at this point will later on be matched against early platform drivers.
2. Parsing kernel command line
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The architecture code calls parse_early_param() to parse the kernel
command line. This will execute all matching early_param() callbacks.
User specified early platform devices will be registered at this point.
For the early serial console case the user can specify port on the
kernel command line as "earlyprintk=serial.0" where "earlyprintk" is
the class string, "serial" is the name of the platfrom driver and
0 is the platform device id. If the id is -1 then the dot and the
id can be omitted.
3. Installing early platform drivers belonging to a certain class
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The architecture code may optionally force registration of all early
platform drivers belonging to a certain class using the function
early_platform_driver_register_all(). User specified devices from
step 2 have priority over these. This step is omitted by the serial
driver example since the early serial driver code should be disabled
unless the user has specified port on the kernel command line.
4. Early platform driver registration
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Compiled-in platform drivers making use of early_platform_init() are
automatically registered during step 2 or 3. The serial driver example
should use early_platform_init("earlyprintk", &platform_driver).
5. Probing of early platform drivers belonging to a certain class
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The architecture code calls early_platform_driver_probe() to match
registered early platform devices associated with a certain class with
registered early platform drivers. Matched devices will get probed().
This step can be executed at any point during the early boot. As soon
as possible may be good for the serial port case.
6. Inside the early platform driver probe()
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The driver code needs to take special care during early boot, especially
when it comes to memory allocation and interrupt registration. The code
in the probe() function can use is_early_platform_device() to check if
it is called at early platform device or at the regular platform device
time. The early serial driver performs register_console() at this point.

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.

- 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)

|__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 )

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.
The 'alarms' file provides access to the two alarm bits provided by
the G760A chip's status register: Bit 0 is set when the actual fan
speed differs more than 20% with respect to the programmed fan speed;
bit 1 is set when fan speed is below 1920 RPM.
The g760a driver will not update its values more frequently than every
other second; reading them more often will do no harm, but will return
'old' values.

The P_Key for any interface is given by the "pkey" file, and the

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.
This normally happens automatically when the system detects the USB
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.
which drives the device through the regular serial line driver. It must
be attached to the serial line to which the M101 is connected with the
ldattach(8) command (requires util-linux-ng release 2.14 or later), for
example:
ldattach GIGASET_M101 /dev/ttyS1
This will open the device file, attach the line discipline to it, 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 ldattach
before disconnecting the device. To have this happen automatically at
system startup/shutdown on an LSB compatible system, create and activate
an appropriate LSB startup script /etc/init.d/gigaset. (The init name
'gigaset' is officially assigned to this project by LANANA.)
Alternatively, just add the 'ldattach' command line to /etc/rc.local.

=== 7 Kbuild Variables
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

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.

--- What is TOMOYO? ---
TOMOYO is a name-based MAC extension (LSM module) for the Linux kernel.
LiveCD-based tutorials are available at
http://tomoyo.sourceforge.jp/en/1.6.x/1st-step/ubuntu8.04-live/
http://tomoyo.sourceforge.jp/en/1.6.x/1st-step/centos5-live/ .
Though these tutorials use non-LSM version of TOMOYO, they are useful for you
to know what TOMOYO is.
--- How to enable TOMOYO? ---
Build the kernel with CONFIG_SECURITY_TOMOYO=y and pass "security=tomoyo" on
kernel's command line.
Please see http://tomoyo.sourceforge.jp/en/2.2.x/ for details.
--- Where is documentation? ---
User <-> Kernel interface documentation is available at
http://tomoyo.sourceforge.jp/en/2.2.x/policy-reference.html .
Materials we prepared for seminars and symposiums are available at
http://sourceforge.jp/projects/tomoyo/docs/?category_id=532&language_id=1 .
Below lists are chosen from three aspects.

History of TOMOYO?
Realities of Mainlining
http://sourceforge.jp/projects/tomoyo/docs/lfj2008.pdf
--- What is future plan? ---
We believe that inode based security and name based security are complementary
and both should be used together. But unfortunately, so far, we cannot enable
multiple LSM modules at the same time. We feel sorry that you have to give up
SELinux/SMACK/AppArmor etc. when you want to use TOMOYO.
We hope that LSM becomes stackable in future. Meanwhile, you can use non-LSM
version of TOMOYO, available at http://tomoyo.sourceforge.jp/en/1.6.x/ .
LSM version of TOMOYO is a subset of non-LSM version of TOMOYO. We are planning
to port non-LSM version's functionalities to LSM versions.

PXA-Camera Host Driver
======================
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.

static int subdev_command(struct i2c_client *client, unsigned cmd, void *arg)
{
return v4l2_subdev_command(i2c_get_clientdata(client), cmd, arg);

If driver->command is never used then you can leave this out. Eventually the
driver->command usage should be removed from v4l.
Make sure to call v4l2_device_unregister_subdev(sd) when the remove() callback
is called. This will unregister the sub-device from the bridge driver. It is
safe to call this even if the sub-device was never registered.

The bridge driver also has some helper functions it can use:
struct v4l2_subdev *sd = v4l2_i2c_new_subdev(adapter, "module_foo", "chipid", 0x36);
struct v4l2_subdev *sd = v4l2_i2c_new_subdev(v4l2_dev, adapter,
"module_foo", "chipid", 0x36);
This loads the given module (can be NULL if no module needs to be loaded) and
calls i2c_new_device() with the given i2c_adapter and chip/address arguments.
If all goes well, then it registers the subdev with the v4l2_device. It gets
the v4l2_device by calling i2c_get_adapdata(adapter), so you should make sure
to call i2c_set_adapdata(adapter, v4l2_device) when you setup the i2c_adapter
in your driver.
If all goes well, then it registers the subdev with the v4l2_device.
You can also use v4l2_i2c_new_probed_subdev() which is very similar to
v4l2_i2c_new_subdev(), except that it has an array of possible I2C addresses

List: linux-kernel
Subject: Re: active_mm
From: Linus Torvalds <torvalds () transmeta ! com>
Date: 1999-07-30 21:36:24
Cc'd to linux-kernel, because I don't write explanations all that often,
and when I do I feel better about more people reading them.

Basically, the new setup is:
- we have "real address spaces" and "anonymous address spaces". The
difference is that an anonymous address space doesn't care about the
user-level page tables at all, so when we do a context switch into an
anonymous address space we just leave the previous address space
active.
The obvious use for a "anonymous address space" is any thread that
doesn't need any user mappings - all kernel threads basically fall into
this category, but even "real" threads can temporarily say that for
some amount of time they are not going to be interested in user space,
and that the scheduler might as well try to avoid wasting time on
switching the VM state around. Currently only the old-style bdflush
sync does that.
- "tsk->mm" points to the "real address space". For an anonymous process,
tsk->mm will be NULL, for the logical reason that an anonymous process
really doesn't _have_ a real address space at all.
- however, we obviously need to keep track of which address space we
"stole" for such an anonymous user. For that, we have "tsk->active_mm",
which shows what the currently active address space is.
The rule is that for a process with a real address space (ie tsk->mm is
non-NULL) the active_mm obviously always has to be the same as the real
one.
For a anonymous process, tsk->mm == NULL, and tsk->active_mm is the
"borrowed" mm while the anonymous process is running. When the
anonymous process gets scheduled away, the borrowed address space is
returned and cleared.
To support all that, the "struct mm_struct" now has two counters: a
"mm_users" counter that is how many "real address space users" there are,
and a "mm_count" counter that is the number of "lazy" users (ie anonymous
users) plus one if there are any real users.
Usually there is at least one real user, but it could be that the real
user exited on another CPU while a lazy user was still active, so you do
actually get cases where you have a address space that is _only_ used by
lazy users. That is often a short-lived state, because once that thread
gets scheduled away in favour of a real thread, the "zombie" mm gets
released because "mm_users" becomes zero.
Also, a new rule is that _nobody_ ever has "init_mm" as a real MM any
more. "init_mm" should be considered just a "lazy context when no other
context is available", and in fact it is mainly used just at bootup when
no real VM has yet been created. So code that used to check
if (current->mm == &init_mm)
should generally just do
if (!current->mm)
instead (which makes more sense anyway - the test is basically one of "do
we have a user context", and is generally done by the page fault handler
and things like that).
Anyway, I put a pre-patch-2.3.13-1 on ftp.kernel.org just a moment ago,
because it slightly changes the interfaces to accomodate the alpha (who
would have thought it, but the alpha actually ends up having one of the
ugliest context switch codes - unlike the other architectures where the MM
and register state is separate, the alpha PALcode joins the two, and you
need to switch both together).
