23 This driver adds support for the ACPI-WMI (Windows Management
24 Instrumentation) mapper device (PNP0C14) found on some systems.
26 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
27 ACPI firmware to userspace - this is done through various vendor
28 defined methods and data blocks in a PNP0C14 device, which are then
29 made available for userspace to call.
31 The implementation of this in Linux currently only exposes this to
32 other kernel space drivers.
34 This driver is a required dependency to build the firmware specific
35 drivers needed on many machines, including Acer and HP laptops.

675 and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
676 Note that if you want ThinkPad-ACPI to be built-in instead of

688 Enables monitoring of the built-in console audio output control
689 (headphone and speakers), which is operated by the mute and (in
690 some ThinkPad models) volume hotkeys.
692 If this option is enabled, ThinkPad-ACPI will export an ALSA card
693 with a single read-only mixer control, which should be used for
694 on-screen-display feedback purposes by the Desktop Environment.
696 Optionally, the driver will also allow software control (the
697 ALSA mixer will be made read-write). Please refer to the driver
698 documentation for details.
700 All IBM models have both volume and mute control. Newer Lenovo

721 If you are not sure, say N here.
723 config THINKPAD_ACPI_UNSAFE_LEDS
724 bool "Allow control of important LEDs (unsafe)"
725 depends on THINKPAD_ACPI
727 Overriding LED state on ThinkPads can mask important
728 firmware alerts (like critical battery condition), or misled
729 the user into damaging the hardware (undocking or ejecting
730 the bay while buses are still active), etc.
732 LED control on the ThinkPad is write-only (with very few
733 exceptions on very ancient models), which makes it
734 impossible to know beforehand if important information will
735 be lost when one changes LED state.
737 Users that know what they are doing can enable this option
738 and the driver will allow control of every LED, including
739 the ones on the dock stations.
741 Never enable this option on a distribution kernel.
743 Say N here, unless you are building a kernel for your own
744 use, and need to control the important firmware LEDs.

747 bool "Video output control support"
748 depends on THINKPAD_ACPI
751 Allows the thinkpad_acpi driver to provide an interface to control
752 the various video output ports.
754 This feature often won't work well, depending on ThinkPad model,
755 display state, video output devices in use, whether there is a X
756 server running, phase of the moon, and the current mood of
757 Schroedinger's cat. If you can use X.org's RandR to control
758 your ThinkPad's video output ports instead of this feature,
759 don't think twice: do it and say N here to save memory and avoid
760 bad interactions with X.org.
762 NOTE: access to this feature is limited to processes with the
763 CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
764 where it interacts badly with X.org.
766 If you are not sure, say Y here but do try to check if you could
767 be using X.org RandR instead.
769 config THINKPAD_ACPI_HOTKEY_POLL
770 bool "Support NVRAM polling for hot keys"
771 depends on THINKPAD_ACPI
774 Some thinkpad models benefit from NVRAM polling to detect a few of
775 the hot key press events. If you know your ThinkPad model does not
776 need to do NVRAM polling to support any of the hot keys you use,
777 unselecting this option will save about 1kB of memory.
779 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
780 unlikely to need NVRAM polling in their latest BIOS versions.
782 NVRAM polling can detect at most the following keys: ThinkPad/Access
783 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
784 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
786 If you are not sure, say Y here. The driver enables polling only if
787 it is strictly necessary to do so.

793 Many Bay Trail and Cherry Trail devices come with a camera attached
794 to Intel's Image Signal Processor. Linux currently does not have a
795 driver for these, so they do not work as a camera. Some of these
796 camera's have a LED which is controlled through a GPIO.
798 Some of these devices have a firmware issue where the LED gets turned
799 on at boot. This driver will turn the LED off at boot and also allows
800 controlling the LED (repurposing it) through the sysfs LED interface.
802 Which GPIO is attached to the LED is usually not described in the
803 ACPI tables, so this driver contains per-system info about the GPIO
804 inside the driver, this means that this driver only works on systems
