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.

35 drivers needed on many machines, including Acer and HP laptops.

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

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

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

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

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

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

811 On these machines, all system configuration is handled through the

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