Documentation/ABI/obsolete/proc-pid-oom_adj 0 → 100644
浏览文件 @ 1bb95834
What: /proc/<pid>/oom_adj
When: August 2012
Why: /proc/<pid>/oom_adj allows userspace to influence the oom killer's
badness heuristic used to determine which task to kill when the kernel
is out of memory.
The badness heuristic has since been rewritten since the introduction of
this tunable such that its meaning is deprecated. The value was
implemented as a bitshift on a score generated by the badness()
function that did not have any precise units of measure. With the
rewrite, the score is given as a proportion of available memory to the
task allocating pages, so using a bitshift which grows the score
exponentially is, thus, impossible to tune with fine granularity.
A much more powerful interface, /proc/<pid>/oom_score_adj, was
introduced with the oom killer rewrite that allows users to increase or
decrease the badness() score linearly. This interface will replace
/proc/<pid>/oom_adj.
A warning will be emitted to the kernel log if an application uses this
deprecated interface. After it is printed once, future warnings will be
suppressed until the kernel is rebooted.

浏览文件 @ 1bb95834
What: /sys/block/zram<id>/disksize
Date: August 2010
Contact: Nitin Gupta <ngupta@vflare.org>
Description:
The disksize file is read-write and specifies the disk size
which represents the limit on the *uncompressed* worth of data
that can be stored in this disk.
What: /sys/block/zram<id>/initstate
Date: August 2010
Contact: Nitin Gupta <ngupta@vflare.org>
Description:
The disksize file is read-only and shows the initialization
state of the device.
What: /sys/block/zram<id>/reset
Date: August 2010
Contact: Nitin Gupta <ngupta@vflare.org>
Description:
The disksize file is write-only and allows resetting the
device. The reset operation frees all the memory assocaited
with this device.
What: /sys/block/zram<id>/num_reads
Date: August 2010
Contact: Nitin Gupta <ngupta@vflare.org>
Description:
The num_reads file is read-only and specifies the number of
reads (failed or successful) done on this device.
What: /sys/block/zram<id>/num_writes
Date: August 2010
Contact: Nitin Gupta <ngupta@vflare.org>
Description:
The num_writes file is read-only and specifies the number of
writes (failed or successful) done on this device.
What: /sys/block/zram<id>/invalid_io
Date: August 2010
Contact: Nitin Gupta <ngupta@vflare.org>
Description:
The invalid_io file is read-only and specifies the number of
non-page-size-aligned I/O requests issued to this device.
What: /sys/block/zram<id>/notify_free
Date: August 2010
Contact: Nitin Gupta <ngupta@vflare.org>
Description:
The notify_free file is read-only and specifies the number of
swap slot free notifications received by this device. These
notifications are send to a swap block device when a swap slot
is freed. This statistic is applicable only when this disk is
being used as a swap disk.
What: /sys/block/zram<id>/discard
Date: August 2010
Contact: Nitin Gupta <ngupta@vflare.org>
Description:
The discard file is read-only and specifies the number of
discard requests received by this device. These requests
provide information to block device regarding blocks which are
no longer used by filesystem.
What: /sys/block/zram<id>/zero_pages
Date: August 2010
Contact: Nitin Gupta <ngupta@vflare.org>
Description:
The zero_pages file is read-only and specifies number of zero
filled pages written to this disk. No memory is allocated for
such pages.
What: /sys/block/zram<id>/orig_data_size
Date: August 2010
Contact: Nitin Gupta <ngupta@vflare.org>
Description:
The orig_data_size file is read-only and specifies uncompressed
size of data stored in this disk. This excludes zero-filled
pages (zero_pages) since no memory is allocated for them.
Unit: bytes
What: /sys/block/zram<id>/compr_data_size
Date: August 2010
Contact: Nitin Gupta <ngupta@vflare.org>
Description:
The compr_data_size file is read-only and specifies compressed
size of data stored in this disk. So, compression ratio can be
calculated using orig_data_size and this statistic.
Unit: bytes
What: /sys/block/zram<id>/mem_used_total
Date: August 2010
Contact: Nitin Gupta <ngupta@vflare.org>
Description:
The mem_used_total file is read-only and specifies the amount
of memory, including allocator fragmentation and metadata
overhead, allocated for this disk. So, allocator space
efficiency can be calculated using compr_data_size and this
statistic.
Unit: bytes

<title>Description</title>
<para>The following four pixel formats are raw sRGB / Bayer formats with
10 bits per colour. Each colour component is stored in a 16-bit word, with 6
unused high bits filled with zeros. Each n-pixel row contains n/2 green samples
and n/2 blue or red samples, with alternating red and blue rows. Bytes are
stored in memory in little endian order. They are conventionally described
as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an example of one of these
formats</para>

<title>Description</title>
<para>This is commonly the native format of digital cameras,
reflecting the arrangement of sensors on the CCD device. Only one red,
green or blue value is given for each pixel. Missing components must
be interpolated from neighbouring pixels. From left to right the first
row consists of a red and green value, the second row of a green and
blue value. This scheme repeats to the right and down for every two
columns and rows.</para>

Using Coccinelle on (modified) files
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
To apply Coccinelle on a file basis, instead of a directory basis, the
following command may be used:
make C=1 CHECK="scripts/coccicheck"
To check only newly edited code, use the value 2 for the C flag, i.e.
make C=2 CHECK="scripts/coccicheck"
This runs every semantic patch in scripts/coccinelle by default. The
COCCI variable may additionally be used to only apply a single
semantic patch as shown in the previous section.
The "chain" mode is the default. You can select another one with the
MODE variable explained above.

To extract firmware for the DM04/QQBOX you need to copy the
following file(s) to this directory.
for DM04+/QQBOX LME2510C (Sharp 7395 Tuner)
-------------------------------------------
The Sharp 7395 driver can be found in windows/system32/driver
US2A0D.sys (dated 17 Mar 2009)
and run
./get_dvb_firmware lme2510c_s7395
will produce
dvb-usb-lme2510c-s7395.fw
An alternative but older firmware can be found on the driver

---------------------------
The following files exist in /proc/viafb
supported_output_devices
This read-only file contains a full ',' seperated list containing all
output devices that could be available on your platform. It is likely
that not all of those have a connector on your hardware but it should
provide a good starting point to figure out which of those names match
a real connector.
Example:
# cat /proc/viafb/supported_output_devices
iga1/output_devices
iga2/output_devices
These two files are readable and writable. iga1 and iga2 are the two
independent units that produce the screen image. Those images can be
forwarded to one or more output devices. Reading those files is a way
to query which output devices are currently used by an iga.
Example:
# cat /proc/viafb/iga1/output_devices
If there are no output devices printed the output of this iga is lost.
This can happen for example if only one (the other) iga is used.
Writing to these files allows adjusting the output devices during
runtime. One can add new devices, remove existing ones or switch
between igas. Essentially you can write a ',' seperated list of device
names (or a single one) in the same format as the output to those
files. You can add a '+' or '-' as a prefix allowing simple addition
and removal of devices. So a prefix '+' adds the devices from your list
to the already existing ones, '-' removes the listed devices from the
existing ones and if no prefix is given it replaces all existing ones
with the listed ones. If you remove devices they are expected to turn
off. If you add devices that are already part of the other iga they are
removed there and added to the new one.
Examples:
Add CRT as output device to iga1
# echo +CRT > /proc/viafb/iga1/output_devices
Remove (turn off) DVP1 and LVDS1 as output devices of iga2
# echo -DVP1,LVDS1 > /proc/viafb/iga2/output_devices
Replace all iga1 output devices by CRT
# echo CRT > /proc/viafb/iga1/output_devices

When: kernel 2.6.38

Check: drivers/staging/cpia/cpia.c drivers/staging/stradis/stradis.c
Why: There are some drivers still using V4L1 API, despite all efforts we've done
to migrate. Those drivers are for obsolete hardware that the old maintainer
didn't care (or not have the hardware anymore), and that no other developer
could find any hardware to buy. They probably have no practical usage today,
and people with such old hardware could probably keep using an older version
of the kernel. Those drivers will be moved to staging on 2.6.37 and, if nobody
care enough to port and test them with V4L2 API, they'll be removed on 2.6.38.

Files: drivers/media/video/saa5246a.c drivers/media/video/saa5249.c

Why: The vtx device nodes have been superseded by vbi device nodes
for many years. No applications exist that use the vtx support.
Of the two i2c drivers that actually support this API the saa5249
has been impossible to use for a year now and no known hardware
that supports this device exists. The saa5246a is theoretically
supported by the old mxb boards, but it never actually worked.
In summary: there is no hardware that can use this API and there
are no applications actually implementing this API.
The vtx support still reserves minors 192-223 and we would really
like to reuse those for upcoming new functionality. In the unlikely
event that new hardware appears that wants to use the functionality
provided by the vtx API, then that functionality should be build
around the sliced VBI API instead.

* it is not possible to have a single process handling
a lot of namespaces without falling in a exponential creation time
* we may want to create a namespace without creating a cgroup
The ns_cgroup is replaced by a compatibility flag 'clone_children',
where a newly created cgroup will copy the parent cgroup values.
The userspace has to manually create a cgroup and add a task to
the 'tasks' file.

The ADT7468 has a high-frequency PWM mode, where all PWM outputs are
driven by a 22.5 kHz clock. This is a global mode, not per-PWM output,
which means that setting any PWM frequency above 11.3 kHz will switch
all 3 PWM outputs to a 22.5 kHz frequency. Conversely, setting any PWM
frequency below 11.3 kHz will switch all 3 PWM outputs to a frequency
between 10 and 100 Hz, which can then be tuned separately.

Kernel driver for lp5521
========================
* National Semiconductor LP5521 led driver chip
* Datasheet: http://www.national.com/pf/LP/LP5521.html
Authors: Mathias Nyman, Yuri Zaporozhets, Samu Onkalo
Contact: Samu Onkalo (samu.p.onkalo-at-nokia.com)
Description
-----------
LP5521 can drive up to 3 channels. Leds can be controlled directly via
the led class control interface. Channels have generic names:
lp5521:channelx, where x is 0 .. 2
All three channels can be also controlled using the engine micro programs.
More details of the instructions can be found from the public data sheet.
Control interface for the engines:
x is 1 .. 3
enginex_mode : disabled, load, run
enginex_load : store program (visible only in engine load mode)
Example (start to blink the channel 2 led):
cd /sys/class/leds/lp5521:channel2/device
echo "load" > engine3_mode
echo "037f4d0003ff6000" > engine3_load
echo "run" > engine3_mode
stop the engine:
echo "disabled" > engine3_mode
sysfs contains a selftest entry.
The test communicates with the chip and checks that
the clock mode is automatically set to the requested one.
Each channel has its own led current settings.
/sys/class/leds/lp5521:channel0/led_current - RW
/sys/class/leds/lp5521:channel0/max_current - RO
Format: 10x mA i.e 10 means 1.0 mA

Kernel driver for lp5523
========================
* National Semiconductor LP5523 led driver chip
* Datasheet: http://www.national.com/pf/LP/LP5523.html
Authors: Mathias Nyman, Yuri Zaporozhets, Samu Onkalo
Contact: Samu Onkalo (samu.p.onkalo-at-nokia.com)
Description
-----------
LP5523 can drive up to 9 channels. Leds can be controlled directly via
the led class control interface. Channels have generic names:
lp5523:channelx where x is 0...8
The chip provides 3 engines. Each engine can control channels without
interaction from the main CPU. Details of the micro engine code can be found
from the public data sheet. Leds can be muxed to different channels.
Control interface for the engines:
x is 1 .. 3
enginex_mode : disabled, load, run
enginex_load : microcode load (visible only in load mode)
enginex_leds : led mux control (visible only in load mode)
cd /sys/class/leds/lp5523:channel2/device
echo "load" > engine3_mode
echo "9d80400004ff05ff437f0000" > engine3_load
echo "111111111" > engine3_leds
echo "run" > engine3_mode
sysfs contains a selftest entry. It measures each channel
voltage level and checks if it looks reasonable. If the level is too high,
the led is missing; if the level is too low, there is a short circuit.
Selftest uses always the current from the platform data.
Each channel contains led current settings.

Bo Yang
2 Current Version : 00.00.04.31-rc1
3 Older Version : 00.00.04.17.1-rc1
1. Add the Online Controller Reset (OCR) to the Driver.
OCR is the new feature for megaraid_sas driver which
will allow the fw to do the chip reset which will not
affact the OS behavious.
To add the OCR support, driver need to do:
a). reset the controller chips -- Xscale and Gen2 which
will change the function calls and add the reset function
related to this two chips.
b). during the reset, driver will store the pending cmds
which not returned by FW to driver's pending queue. Driver
will re-issue those pending cmds again to FW after the OCR
finished.
c). In driver's timeout routine, driver will report to
OS as reset. Also driver's queue routine will block the
cmds until the OCR finished.
d). in Driver's ISR routine, if driver get the FW state as
state change, FW in Failure status and FW support online controller
reset (OCR), driver will start to do the controller reset.
e). In driver's IOCTL routine, the application cmds will wait for the
OCR to finish, then issue the cmds to FW.
f). Before driver kill adapter, driver will do last chance of
OCR to see if driver can bring back the FW.
2. Add the support update flag to the driver to tell LSI megaraid_sas
application which driver will support the device update. So application
will not need to do the device update after application add/del the device
from the system.
3. In driver's timeout routine, driver will do three time reset if fw is in
failed state. Driver will kill adapter if can't bring back FW after the
this three times reset.
4. Add the input parameter max_sectors to 1MB support to our GEN2 controller.
customer can use the input paramenter max_sectors to add 1MB support to GEN2
controller.

v4l2_file_operations and locking
--------------------------------
You can set a pointer to a mutex_lock in struct video_device. Usually this
will be either a top-level mutex or a mutex per device node. If you want
finer-grained locking then you have to set it to NULL and do you own locking.
If a lock is specified then all file operations will be serialized on that
lock. If you use videobuf then you must pass the same lock to the videobuf
queue initialize function: if videobuf has to wait for a frame to arrive, then
it will temporarily unlock the lock and relock it afterwards. If your driver
also waits in the code, then you should do the same to allow other processes
to access the device node while the first process is waiting for something.
The implementation of a hotplug disconnect should also take the lock before
calling v4l2_device_disconnect.

config JUMP_LABEL
bool "Optimize trace point call sites"
depends on HAVE_ARCH_JUMP_LABEL
help
If it is detected that the compiler has support for "asm goto",
the kernel will compile trace point locations with just a
nop instruction. When trace points are enabled, the nop will
be converted to a jump to the trace function. This technique
lowers overhead and stress on the branch prediction of the
processor.
On i386, options added to the compiler flags may increase
the size of the kernel slightly.
