moved to the drivers/misc tree and renamed to thinkpad-acpi for kernel
2.6.22, and release 0.14.
The driver is named "thinkpad-acpi". In some places, like module
names, "thinkpad_acpi" is used because of userspace issues.
"tpacpi" is used as a shorthand where "thinkpad-acpi" would be too
long due to length limitations on some Linux kernel versions.

Brightness hotkey notes:
These are the current sane choices for brightness key mapping in
thinkpad-acpi:
For IBM and Lenovo models *without* ACPI backlight control (the ones on
which thinkpad-acpi will autoload its backlight interface by default,
and on which ACPI video does not export a backlight interface):
1. Don't enable or map the brightness hotkeys in thinkpad-acpi, as
these older firmware versions unfortunately won't respect the hotkey
mask for brightness keys anyway, and always reacts to them. This
usually work fine, unless X.org drivers are doing something to block
the BIOS. In that case, use (3) below. This is the default mode of
operation.
2. Enable the hotkeys, but map them to something else that is NOT
KEY_BRIGHTNESS_UP/DOWN or any other keycode that would cause
userspace to try to change the backlight level, and use that as an
on-screen-display hint.
3. IF AND ONLY IF X.org drivers find a way to block the firmware from
automatically changing the brightness, enable the hotkeys and map
them to KEY_BRIGHTNESS_UP and KEY_BRIGHTNESS_DOWN, and feed that to
something that calls xbacklight. thinkpad-acpi will not be able to
change brightness in that case either, so you should disable its
backlight interface.
For Lenovo models *with* ACPI backlight control:
1. Load up ACPI video and use that. ACPI video will report ACPI
events for brightness change keys. Do not mess with thinkpad-acpi
defaults in this case. thinkpad-acpi should not have anything to do
with backlight events in a scenario where ACPI video is loaded:
brightness hotkeys must be disabled, and the backlight interface is
to be kept disabled as well. This is the default mode of operation.
2. Do *NOT* load up ACPI video, enable the hotkeys in thinkpad-acpi,
and map them to KEY_BRIGHTNESS_UP and KEY_BRIGHTNESS_DOWN. Process
these keys on userspace somehow (e.g. by calling xbacklight).

is "tpacpi::thinklight".
Due to limitations in the sysfs LED class, if the status of the thinklight

LED control

sysfs attributes: as per LED class, see below for names
Some of the LED indicators can be controlled through this feature. On
some older ThinkPad models, it is possible to query the status of the
LED indicators as well. Newer ThinkPads cannot query the real status
of the LED indicators.
Some of the LED indicators can be controlled through this feature. The
available commands are:
procfs notes:
The available commands are:
echo '<led number> on' >/proc/acpi/ibm/led
echo '<led number> off' >/proc/acpi/ibm/led
echo '<led number> blink' >/proc/acpi/ibm/led
echo '<LED number> on' >/proc/acpi/ibm/led
echo '<LED number> off' >/proc/acpi/ibm/led
echo '<LED number> blink' >/proc/acpi/ibm/led
The <led number> range is 0 to 7. The set of LEDs that can be
controlled varies from model to model. Here is the mapping on the X40:
The <LED number> range is 0 to 7. The set of LEDs that can be
controlled varies from model to model. Here is the common ThinkPad
mapping:
0 - power
1 - battery (orange)
2 - battery (green)
3 - UltraBase
3 - UltraBase/dock
4 - UltraBay
5 - UltraBase battery slot
6 - (unknown)
7 - standby
All of the above can be turned on and off and can be made to blink.
sysfs notes:
The ThinkPad LED sysfs interface is described in detail by the LED class
documentation, in Documentation/leds-class.txt.
The leds are named (in LED ID order, from 0 to 7):
"tpacpi::power", "tpacpi:orange:batt", "tpacpi:green:batt",
"tpacpi::dock_active", "tpacpi::bay_active", "tpacpi::dock_batt",
"tpacpi::unknown_led", "tpacpi::standby".
Due to limitations in the sysfs LED class, if the status of the LED
indicators cannot be read due to an error, thinkpad-acpi will report it as
a brightness of zero (same as LED off).
If the thinkpad firmware doesn't support reading the current status,
trying to read the current LED brightness will just return whatever
brightness was last written to that attribute.
These LEDs can blink using hardware acceleration. To request that a
ThinkPad indicator LED should blink in hardware accelerated mode, use the
"timer" trigger, and leave the delay_on and delay_off parameters set to
zero (to request hardware acceleration autodetection).
