What: /sys/firmware/acpi/namespace
When: 2.6.21
Why: The ACPI namespace is effectively the symbol list for
the BIOS. The device names are completely arbitrary
and have no place being exposed to user-space.
For those interested in the BIOS ACPI namespace,
the BIOS can be extracted and disassembled with acpidump
and iasl as documented in the pmtools package here:

What: ACPI procfs interface
When: July 2007
Why: After ACPI sysfs conversion, ACPI attributes will be duplicated
in sysfs and the ACPI procfs interface should be removed.
When: July 2008
Why: ACPI sysfs conversion should be finished by January 2008.
ACPI procfs interface will be removed in July 2008 so that
there is enough time for the user space to catch up.

subsystems are not documented here, nor are they tracked by this
attribute.
Changes to the thinkpad-acpi sysfs interface are only considered
non-experimental when they are submitted to Linux mainline, at which
point the changes in this interface are documented and interface_version
may be updated. If you are using any thinkpad-acpi features not yet
sent to mainline for merging, you do so on your own risk: these features
may disappear, or be implemented in a different and incompatible way by
the time they are merged in Linux mainline.
Changes that are backwards-compatible by nature (e.g. the addition of
attributes that do not change the way the other attributes work) do not
always warrant an update of interface_version. Therefore, one must
expect that an attribute might not be there, and deal with it properly
(an attribute not being there *is* a valid way to make it clear that a
feature is not available in sysfs).
Hot keys
--------
procfs: /proc/acpi/ibm/hotkey
sysfs device attribute: hotkey_*
Without this driver, only the Fn-F4 key (sleep button) generates an
ACPI event. With the driver loaded, the hotkey feature enabled and the
mask set (see below), the various hot keys generate ACPI events in the
In a ThinkPad, the ACPI HKEY handler is responsible for comunicating
some important events and also keyboard hot key presses to the operating
system. Enabling the hotkey functionality of thinkpad-acpi signals the
firmware that such a driver is present, and modifies how the ThinkPad
firmware will behave in many situations.
When the hotkey feature is enabled and the hot key mask is set (see
below), the various hot keys either generate ACPI events in the
following format:
ibm/hotkey HKEY 00000080 0000xxxx
The last four digits vary depending on the key combination pressed.
All labeled Fn-Fx key combinations generate distinct events. In
addition, the lid microswitch and some docking station buttons may
also generate such events.
or events over the input layer. The input layer support accepts the
standard IOCTLs to remap the keycodes assigned to each hotkey.
The bit mask allows some control over which hot keys generate ACPI
events. Not all bits in the mask can be modified. Not all bits that
can be modified do anything. Not all hot keys can be individually
controlled by the mask. Most recent ThinkPad models honor the
following bits (assuming the hot keys feature has been enabled):
When the input device is open, the driver will suppress any ACPI hot key
events that get translated into a meaningful input layer event, in order
to avoid sending duplicate events to userspace. Hot keys that are
mapped to KEY_RESERVED in the keymap are not translated, and will always
generate an ACPI ibm/hotkey HKEY event, and no input layer events.
key bit behavior when set behavior when unset
The hot key bit mask allows some control over which hot keys generate
events. If a key is "masked" (bit set to 0 in the mask), the firmware
will handle it. If it is "unmasked", it signals the firmware that
thinkpad-acpi would prefer to handle it, if the firmware would be so
kind to allow it (and it often doesn't!).
Fn-F3 always generates ACPI event
Fn-F4 always generates ACPI event
Fn-F5 0010 generate ACPI event enable/disable Bluetooth
Fn-F7 0040 generate ACPI event switch LCD and external display
Fn-F8 0080 generate ACPI event expand screen or none
Fn-F9 0100 generate ACPI event none
Fn-F12 always generates ACPI event
Not all bits in the mask can be modified. Not all bits that can be
modified do anything. Not all hot keys can be individually controlled
by the mask. Some models do not support the mask at all, and in those
models, hot keys cannot be controlled individually. The behaviour of
the mask is, therefore, higly dependent on the ThinkPad model.
Some models do not support all of the above. For example, the T30 does
not support Fn-F5 and Fn-F9. Other models do not support the mask at
all. On those models, hot keys cannot be controlled individually.
Note that unmasking some keys prevents their default behavior. For
example, if Fn+F5 is unmasked, that key will no longer enable/disable
Bluetooth by itself.
Note that enabling ACPI events for some keys prevents their default
behavior. For example, if events for Fn-F5 are enabled, that key will
no longer enable/disable Bluetooth by itself. This can still be done
from an acpid handler for the ibm/hotkey event.
Note also that not all Fn key combinations are supported through
ACPI. For example, on the X40, the brightness, volume and "Access IBM"
buttons do not generate ACPI events even with this driver. They *can*
be used through the "ThinkPad Buttons" utility, see

A Hot key is mapped to a single input layer EV_KEY event, possibly

Do not use the EV_MSC MSC_SCAN events to process keys. They are to be
used as a helper to remap keys, only. They are particularly useful when
remapping KEY_UNKNOWN keys.
The events are available in an input device, with the following id:

0x17aa (PCI_VENDOR_ID_LENOVO)
product: 0x5054 ("TP")
version: 0x4101
The version will have its LSB incremented if the keymap changes in a
backwards-compatible way. The MSB shall always be 0x41 for this input
device. If the MSB is not 0x41, do not use the device as described in
this section, as it is either something else (e.g. another input device
exported by a thinkpad driver, such as HDAPS) or its functionality has
been changed in a non-backwards compatible way.
Adding other event types for other functionalities shall be considered a
backwards-compatible change for this input device.

The ThinkPad firmware does not allow one to differentiate when most hot
keys are pressed or released (either that, or we don't know how to, yet).
For these keys, the driver generates a set of events for a key press and
immediately issues the same set of events for a key release. It is
unknown by the driver if the ThinkPad firmware triggered these events on
hot key press or release, but the firmware will do it for either one, not
both.
If a key is mapped to KEY_RESERVED, it generates no input events at all,
and it may generate a legacy thinkpad-acpi ACPI hotkey event.
If a key is mapped to KEY_UNKNOWN, it generates an input event that
includes an scan code, and it may also generate a legacy thinkpad-acpi
ACPI hotkey event.
If a key is mapped to anything else, it will only generate legacy
thinkpad-acpi ACPI hotkey events if nobody has opened the input device.

procfs: /proc/acpi/ibm/cmos
sysfs device attribute: cmos_command
This feature is used internally by the ACPI firmware to control the
ThinkLight on most newer ThinkPad models. It may also control LCD
brightness, sounds volume and more, but only on some models.
This feature is mostly used internally by the ACPI firmware to keep the legacy
CMOS NVRAM bits in sync with the current machine state, and to record this
state so that the ThinkPad will retain such settings across reboots.
Some of these commands actually perform actions in some ThinkPad models, but
this is expected to disappear more and more in newer models. As an example, in
a T43 and in a X40, commands 12 and 13 still control the ThinkLight state for
real, but commands 0 to 2 don't control the mixer anymore (they have been
phased out) and just update the NVRAM.
The range of valid cmos command numbers is 0 to 21, but not all have an
effect and the behavior varies from model to model. Here is the behavior
on the X40 (tpb is the ThinkPad Buttons utility):
0 - no effect but tpb reports "Volume down"
1 - no effect but tpb reports "Volume up"
2 - no effect but tpb reports "Mute on"
3 - simulate pressing the "Access IBM" button
4 - LCD brightness up
