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.

2.4.1: STAGING TREES
The kernel source tree now contains the drivers/staging/ directory, where
many sub-directories for drivers or filesystems that are on their way to
being added to the kernel tree live. They remain in drivers/staging while
they still need more work; once complete, they can be moved into the
kernel proper. This is a way to keep track of drivers that aren't
up to Linux kernel coding or quality standards, but people may want to use
them and track development.
Greg Kroah-Hartman currently (as of 2.6.36) maintains the staging tree.
Drivers that still need work are sent to him, with each driver having
its own subdirectory in drivers/staging/. Along with the driver source
files, a TODO file should be present in the directory as well. The TODO
file lists the pending work that the driver needs for acceptance into
the kernel proper, as well as a list of people that should be Cc'd for any
patches to the driver. Staging drivers that don't currently build should
have their config entries depend upon CONFIG_BROKEN. Once they can
be successfully built without outside patches, CONFIG_BROKEN can be removed.

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.

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 "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.
