437 This is a driver for the IBM and Lenovo ThinkPad laptops. It adds

439 output switching, ThinkLight control, UltraBay eject and more.
440 For more information about this driver see
441 <file:Documentation/laptops/thinkpad-acpi.txt> and
442 <http://ibm-acpi.sf.net/> .
444 This driver was formerly known as ibm-acpi.
446 Extra functionality will be available if the rfkill (CONFIG_RFKILL)
447 and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
448 Note that if you want ThinkPad-ACPI to be built-in instead of
449 modular, ALSA and rfkill will also have to be built-in.
451 If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.
453 config THINKPAD_ACPI_ALSA_SUPPORT
454 bool "Console audio control ALSA interface"
455 depends on THINKPAD_ACPI
457 depends on SND = y || THINKPAD_ACPI = SND
460 Enables monitoring of the built-in console audio output control
461 (headphone and speakers), which is operated by the mute and (in
462 some ThinkPad models) volume hotkeys.
464 If this option is enabled, ThinkPad-ACPI will export an ALSA card
465 with a single read-only mixer control, which should be used for
466 on-screen-display feedback purposes by the Desktop Environment.
468 Optionally, the driver will also allow software control (the
469 ALSA mixer will be made read-write). Please refer to the driver
470 documentation for details.
472 All IBM models have both volume and mute control. Newer Lenovo
473 models only have mute control (the volume hotkeys are just normal
474 keys and volume control is done through the main HDA mixer).
476 config THINKPAD_ACPI_DEBUGFACILITIES
477 bool "Maintainer debug facilities"
478 depends on THINKPAD_ACPI

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

678 This driver adds support for the ACPI-WMI (Windows Management
679 Instrumentation) mapper device (PNP0C14) found on some systems.
681 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
682 ACPI firmware to userspace - this is done through various vendor
683 defined methods and data blocks in a PNP0C14 device, which are then
684 made available for userspace to call.
686 The implementation of this in Linux currently only exposes this to
687 other kernel space drivers.
689 This driver is a required dependency to build the firmware specific

767 their lack of a BIOS setup menu and APM support.
769 On these machines, all system configuration is handled through the
770 ACPI. This driver is required for access to controls not covered

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