456 For more information about this driver see
457 <file:Documentation/laptops/thinkpad-acpi.txt> and

460 This driver was formerly known as ibm-acpi.
462 Extra functionality will be available if the rfkill (CONFIG_RFKILL)
463 and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
464 Note that if you want ThinkPad-ACPI to be built-in instead of
465 modular, ALSA and rfkill will also have to be built-in.

470 bool "Console audio control ALSA interface"
471 depends on THINKPAD_ACPI

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

502 config THINKPAD_ACPI_DEBUG
503 bool "Verbose debug mode"
504 depends on THINKPAD_ACPI
506 Enables extra debugging information, at the expense of a slightly

509 If you are not sure, say N here.
511 config THINKPAD_ACPI_UNSAFE_LEDS
512 bool "Allow control of important LEDs (unsafe)"
513 depends on THINKPAD_ACPI
515 Overriding LED state on ThinkPads can mask important
516 firmware alerts (like critical battery condition), or misled
517 the user into damaging the hardware (undocking or ejecting
518 the bay while buses are still active), etc.
520 LED control on the ThinkPad is write-only (with very few
521 exceptions on very ancient models), which makes it
522 impossible to know beforehand if important information will
523 be lost when one changes LED state.
525 Users that know what they are doing can enable this option
526 and the driver will allow control of every LED, including
527 the ones on the dock stations.
529 Never enable this option on a distribution kernel.
531 Say N here, unless you are building a kernel for your own
532 use, and need to control the important firmware LEDs.
534 config THINKPAD_ACPI_VIDEO
535 bool "Video output control support"
536 depends on THINKPAD_ACPI
539 Allows the thinkpad_acpi driver to provide an interface to control
540 the various video output ports.
542 This feature often won't work well, depending on ThinkPad model,
543 display state, video output devices in use, whether there is a X
544 server running, phase of the moon, and the current mood of
545 Schroedinger's cat. If you can use X.org's RandR to control
546 your ThinkPad's video output ports instead of this feature,
547 don't think twice: do it and say N here to save memory and avoid
548 bad interactions with X.org.
550 NOTE: access to this feature is limited to processes with the
551 CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
552 where it interacts badly with X.org.
554 If you are not sure, say Y here but do try to check if you could
555 be using X.org RandR instead.
557 config THINKPAD_ACPI_HOTKEY_POLL
558 bool "Support NVRAM polling for hot keys"
559 depends on THINKPAD_ACPI
562 Some thinkpad models benefit from NVRAM polling to detect a few of
563 the hot key press events. If you know your ThinkPad model does not
564 need to do NVRAM polling to support any of the hot keys you use,
565 unselecting this option will save about 1kB of memory.
567 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
568 unlikely to need NVRAM polling in their latest BIOS versions.
570 NVRAM polling can detect at most the following keys: ThinkPad/Access
571 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
572 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
574 If you are not sure, say Y here. The driver enables polling only if
575 it is strictly necessary to do so.
578 tristate "Thinkpad Hard Drive Active Protection System (hdaps)"
582 This driver provides support for the IBM Hard Drive Active Protection
583 System (hdaps), which provides an accelerometer and other misc. data.
584 ThinkPads starting with the R50, T41, and X40 are supported. The
585 accelerometer data is readable via sysfs.
587 This driver also provides an absolute input class device, allowing
588 the laptop to act as a pinball machine-esque joystick.
590 If your ThinkPad is not recognized by the driver, please update to latest
591 BIOS. This is especially the case for some R52 ThinkPads.
593 Say Y here if you have an applicable laptop and want to experience
594 the awesome power of hdaps.

694 This driver adds support for the ACPI-WMI (Windows Management
695 Instrumentation) mapper device (PNP0C14) found on some systems.
697 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
698 ACPI firmware to userspace - this is done through various vendor
699 defined methods and data blocks in a PNP0C14 device, which are then
700 made available for userspace to call.
702 The implementation of this in Linux currently only exposes this to
703 other kernel space drivers.
