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.

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

550 Extra functionality will be available if the rfkill (CONFIG_RFKILL)
551 and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
552 Note that if you want ThinkPad-ACPI to be built-in instead of
553 modular, ALSA and rfkill will also have to be built-in.

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

599 config THINKPAD_ACPI_UNSAFE_LEDS
600 bool "Allow control of important LEDs (unsafe)"
601 depends on THINKPAD_ACPI
603 Overriding LED state on ThinkPads can mask important
604 firmware alerts (like critical battery condition), or misled
605 the user into damaging the hardware (undocking or ejecting
606 the bay while buses are still active), etc.
608 LED control on the ThinkPad is write-only (with very few
609 exceptions on very ancient models), which makes it
610 impossible to know beforehand if important information will
611 be lost when one changes LED state.
613 Users that know what they are doing can enable this option
614 and the driver will allow control of every LED, including
615 the ones on the dock stations.
617 Never enable this option on a distribution kernel.

620 use, and need to control the important firmware LEDs.

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

797 their lack of a BIOS setup menu and APM support.
799 On these machines, all system configuration is handled through the
800 ACPI. This driver is required for access to controls not covered
801 by the general ACPI drivers, such as LCD brightness, video output,
804 This driver differs from the non-ACPI Toshiba laptop driver (located

806 Configuration is accessed by reading and writing text files in the
