Linux ACPI Custom Control Method How To
=======================================
Written by Zhang Rui <rui.zhang@intel.com>
Linux supports customizing ACPI control methods at runtime.
Users can use this to
1. override an existing method which may not work correctly,
or just for debugging purposes.
2. insert a completely new method in order to create a missing
method such as _OFF, _ON, _STA, _INI, etc.
For these cases, it is far simpler to dynamically install a single
control method rather than override the entire DSDT, because kernel
rebuild/reboot is not needed and test result can be got in minutes.
Note: Only ACPI METHOD can be overridden, any other object types like
"Device", "OperationRegion", are not recognized.
Note: The same ACPI control method can be overridden for many times,
and it's always the latest one that used by Linux/kernel.
1. override an existing method
a) get the ACPI table via ACPI sysfs I/F. e.g. to get the DSDT,
just run "cat /sys/firmware/acpi/tables/DSDT > /tmp/dsdt.dat"
b) disassemble the table by running "iasl -d dsdt.dat".
c) rewrite the ASL code of the method and save it in a new file,
d) package the new file (psr.asl) to an ACPI table format.
Here is an example of a customized \_SB._AC._PSR method,
DefinitionBlock ("", "SSDT", 1, "", "", 0x20080715)
{
External (ACON)
Method (\_SB_.AC._PSR, 0, NotSerialized)
{
Store ("In AC _PSR", Debug)
Return (ACON)
}
}
Note that the full pathname of the method in ACPI namespace
should be used.
And remember to use "External" to declare external objects.
e) assemble the file to generate the AML code of the method.
e.g. "iasl psr.asl" (psr.aml is generated as a result)
f) mount debugfs by "mount -t debugfs none /sys/kernel/debug"
g) override the old method via the debugfs by running
"cat /tmp/psr.aml > /sys/kernel/debug/acpi/custom_method"
2. insert a new method
This is easier than overriding an existing method.
We just need to create the ASL code of the method we want to
insert and then follow the step c) ~ g) in section 1.
3. undo your changes
The "undo" operation is not supported for a new inserted method
right now, i.e. we can not remove a method currently.
For an overrided method, in order to undo your changes, please
save a copy of the method original ASL code in step c) section 1,
and redo step c) ~ g) to override the method with the original one.
Note: We can use a kernel with multiple custom ACPI method running,
But each individual write to debugfs can implement a SINGLE
method override. i.e. if we want to insert/override multiple
ACPI methods, we need to redo step c) ~ g) for multiple times.

What: Support for lcd_switch and display_get in asus-laptop driver
When: March 2010
Why: These two features use non-standard interfaces. There are the
only features that really need multiple path to guess what's
the right method name on a specific laptop.
Removing them will allow to remove a lot of code an significantly
clean the drivers.
This will affect the backlight code which won't be able to know
if the backlight is on or off. The platform display file will also be
write only (like the one in eeepc-laptop).
This should'nt affect a lot of user because they usually know
when their display is on or off.

Brightness hotkey notes:
These are the current sane choices for brightness key mapping in
thinkpad-acpi:
Don't mess with the brightness hotkeys in a Thinkpad. If you want
notifications for OSD, use the sysfs backlight class event support.
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).
The driver will do this automatically if it detects that ACPI video
has been disabled.
The driver will issue KEY_BRIGHTNESS_UP and KEY_BRIGHTNESS_DOWN events
automatically for the cases were userspace has to do something to
implement brightness changes. When you override these events, you will
either fail to handle properly the ThinkPads that require explicit
action to change backlight brightness, or the ThinkPads that require
that no action be taken to work properly.

Volume control -- /proc/acpi/ibm/volume
---------------------------------------
Volume control
--------------
This feature allows volume control on ThinkPad models which don't have
a hardware volume knob. The available commands are:
procfs: /proc/acpi/ibm/volume
ALSA: "ThinkPad Console Audio Control", default ID: "ThinkPadEC"
NOTE: by default, the volume control interface operates in read-only
mode, as it is supposed to be used for on-screen-display purposes.
The read/write mode can be enabled through the use of the
"volume_control=1" module parameter.
NOTE: distros are urged to not enable volume_control by default, this
should be done by the local admin only. The ThinkPad UI is for the
console audio control to be done through the volume keys only, and for
the desktop environment to just provide on-screen-display feedback.
Software volume control should be done only in the main AC97/HDA
mixer.
This feature allows volume control on ThinkPad models with a digital
volume knob (when available, not all models have it), as well as
mute/unmute control. The available commands are:
echo up >/proc/acpi/ibm/volume
echo down >/proc/acpi/ibm/volume
echo mute >/proc/acpi/ibm/volume
echo unmute >/proc/acpi/ibm/volume
echo 'level <level>' >/proc/acpi/ibm/volume
The <level> number range is 0 to 15 although not all of them may be
The <level> number range is 0 to 14 although not all of them may be
distinct. The unmute the volume after the mute command, use either the
up or down command (the level command will not unmute the volume).
up or down command (the level command will not unmute the volume), or
the unmute command.
The current volume level and mute state is shown in the file.
The ALSA mixer interface to this feature is still missing, but patches
to add it exist. That problem should be addressed in the not so
distant future.
You can use the volume_capabilities parameter to tell the driver
whether your thinkpad has volume control or mute-only control:
volume_capabilities=1 for mixers with mute and volume control,
volume_capabilities=2 for mixers with only mute control.
If the driver misdetects the capabilities for your ThinkPad model,
please report this to ibm-acpi-devel@lists.sourceforge.net, so that we
can update the driver.
There are two strategies for volume control. To select which one
should be used, use the volume_mode module parameter: volume_mode=1
selects EC mode, and volume_mode=3 selects EC mode with NVRAM backing
(so that volume/mute changes are remembered across shutdown/reboot).
The driver will operate in volume_mode=3 by default. If that does not
work well on your ThinkPad model, please report this to
ibm-acpi-devel@lists.sourceforge.net.
The driver supports the standard ALSA module parameters. If the ALSA
mixer is disabled, the driver will disable all volume functionality.

* than the internal object conversion routines used for implicit object

*
* Integer -> String
* Integer -> Buffer
* String -> Integer
* String -> Buffer
* Buffer -> Integer
* Buffer -> String
