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.

490 ThinkPads starting with the R50, T41, and X40 are supported. The

527 Extra functionality will be available if the rfkill (CONFIG_RFKILL)
528 and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
529 Note that if you want ThinkPad-ACPI to be built-in instead of

535 bool "Console audio control ALSA interface"
536 depends on THINKPAD_ACPI

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

574 If you are not sure, say N here.
576 config THINKPAD_ACPI_UNSAFE_LEDS
577 bool "Allow control of important LEDs (unsafe)"
578 depends on THINKPAD_ACPI
580 Overriding LED state on ThinkPads can mask important
581 firmware alerts (like critical battery condition), or misled
582 the user into damaging the hardware (undocking or ejecting
583 the bay while buses are still active), etc.
585 LED control on the ThinkPad is write-only (with very few
586 exceptions on very ancient models), which makes it
587 impossible to know beforehand if important information will
588 be lost when one changes LED state.
590 Users that know what they are doing can enable this option
591 and the driver will allow control of every LED, including
592 the ones on the dock stations.
594 Never enable this option on a distribution kernel.
596 Say N here, unless you are building a kernel for your own
597 use, and need to control the important firmware LEDs.

600 bool "Video output control support"
601 depends on THINKPAD_ACPI
604 Allows the thinkpad_acpi driver to provide an interface to control
605 the various video output ports.
607 This feature often won't work well, depending on ThinkPad model,
608 display state, video output devices in use, whether there is a X
609 server running, phase of the moon, and the current mood of
610 Schroedinger's cat. If you can use X.org's RandR to control
611 your ThinkPad's video output ports instead of this feature,
612 don't think twice: do it and say N here to save memory and avoid
613 bad interactions with X.org.
615 NOTE: access to this feature is limited to processes with the
616 CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
617 where it interacts badly with X.org.
619 If you are not sure, say Y here but do try to check if you could
620 be using X.org RandR instead.
622 config THINKPAD_ACPI_HOTKEY_POLL
623 bool "Support NVRAM polling for hot keys"
624 depends on THINKPAD_ACPI
627 Some thinkpad models benefit from NVRAM polling to detect a few of
628 the hot key press events. If you know your ThinkPad model does not
629 need to do NVRAM polling to support any of the hot keys you use,
630 unselecting this option will save about 1kB of memory.
632 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
633 unlikely to need NVRAM polling in their latest BIOS versions.
635 NVRAM polling can detect at most the following keys: ThinkPad/Access
636 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
637 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
639 If you are not sure, say Y here. The driver enables polling only if
640 it is strictly necessary to do so.

646 Many Bay Trail and Cherry Trail devices come with a camera attached
647 to Intel's Image Signal Processor. Linux currently does not have a
648 driver for these, so they do not work as a camera. Some of these
649 camera's have a LED which is controlled through a GPIO.
651 Some of these devices have a firmware issue where the LED gets turned
652 on at boot. This driver will turn the LED off at boot and also allows
653 controlling the LED (repurposing it) through the sysfs LED interface.
655 Which GPIO is attached to the LED is usually not described in the
656 ACPI tables, so this driver contains per-system info about the GPIO

686 There are two kinds of INT33FE ACPI device possible: for hardware
687 with USB Type-C and Micro-B connectors. This driver supports both.
689 The INT33FE ACPI device has a CRS table with I2cSerialBusV2
690 resources for Fuel Gauge Controller and (in the Type-C variant)
691 FUSB302 USB Type-C Controller and PI3USB30532 USB switch.
692 This driver instantiates i2c-clients for these, so that standard
693 i2c drivers for these chips can bind to the them.
