Registering the "other mode" notifier fails if that is disabled:
x86_64-linux-ld: drivers/platform/x86/lenovo/wmi-gamezone.o: in function `lwmi_gz_probe':
wmi-gamezone.c:(.text+0x336): undefined reference to `devm_lwmi_om_register_notifier'
This could be fixed by adding a stub helper, but a Kconfig 'select'
seems simpler here.

This is a driver for the IBM and Lenovo ThinkPad laptops. It adds
|
|
support for Fn-Fx key combinations, Bluetooth control, video
|
|
output switching, ThinkLight control, UltraBay eject and more.
|
|
For more information about this driver see
|
|
<file:Documentation/admin-guide/laptops/thinkpad-acpi.rst> and
|
|
<http://ibm-acpi.sf.net/> .
|
|
|
|
This driver was formerly known as ibm-acpi.
|
|
|
|
Extra functionality will be available if the rfkill (CONFIG_RFKILL)
|
|
and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
|
|
Note that if you want ThinkPad-ACPI to be built-in instead of
|
|
modular, ALSA and rfkill will also have to be built-in.
|
|
|
|
If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.

Enables monitoring of the built-in console audio output control
|
|
(headphone and speakers), which is operated by the mute and (in
|
|
some ThinkPad models) volume hotkeys.
|
|
|
|
If this option is enabled, ThinkPad-ACPI will export an ALSA card
|
|
with a single read-only mixer control, which should be used for
|
|
on-screen-display feedback purposes by the Desktop Environment.
|
|
|
|
Optionally, the driver will also allow software control (the
|
|
ALSA mixer will be made read-write). Please refer to the driver
|
|
documentation for details.
|
|
|
|
All IBM models have both volume and mute control. Newer Lenovo
|
|
models only have mute control (the volume hotkeys are just normal
|
|
keys and volume control is done through the main HDA mixer).

help
|

Overriding LED state on ThinkPads can mask important
|
|
firmware alerts (like critical battery condition), or misled
|
|
the user into damaging the hardware (undocking or ejecting
|
|
the bay while buses are still active), etc.
|
|
|
|
LED control on the ThinkPad is write-only (with very few
|
|
exceptions on very ancient models), which makes it
|
|
impossible to know beforehand if important information will
|
|
be lost when one changes LED state.
|
|
|
|
Users that know what they are doing can enable this option
|
|
and the driver will allow control of every LED, including
|
|
the ones on the dock stations.
|
|
|
|
Never enable this option on a distribution kernel.
|
|
|
|
Say N here, unless you are building a kernel for your own
|
|
use, and need to control the important firmware LEDs.

Allows the thinkpad_acpi driver to provide an interface to control

the various video output ports.
|
|
|
|
This feature often won't work well, depending on ThinkPad model,
|
|
display state, video output devices in use, whether there is a X
|
|
server running, phase of the moon, and the current mood of
|
|
Schroedinger's cat. If you can use X.org's RandR to control
|
|
your ThinkPad's video output ports instead of this feature,
|
|
don't think twice: do it and say N here to save memory and avoid
|
|
bad interactions with X.org.
|
|
|
|
NOTE: access to this feature is limited to processes with the
|
|
CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
|
|
where it interacts badly with X.org.
|
|
|
|
If you are not sure, say Y here but do try to check if you could
|
|
be using X.org RandR instead.

config THINKPAD_ACPI_HOTKEY_POLL
|

bool "Support NVRAM polling for hot keys"

depends on THINKPAD_ACPI
|

default y
|
|
help
|
|
Some thinkpad models benefit from NVRAM polling to detect a few of
|
|
the hot key press events. If you know your ThinkPad model does not
|
|
need to do NVRAM polling to support any of the hot keys you use,
|
|
unselecting this option will save about 1kB of memory.
|
|
|
|
ThinkPads T40 and newer, R52 and newer, and X31 and newer are
|
|
unlikely to need NVRAM polling in their latest BIOS versions.
|
|
|
|
NVRAM polling can detect at most the following keys: ThinkPad/Access
|
|
IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
|
|
Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
|
|
|

If you are not sure, say Y here. The driver enables polling only if
|
|
it is strictly necessary to do so.
