434 depends on RFKILL || RFKILL = n

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

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

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

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

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