360 depends on RFKILL || RFKILL = n
361 depends on ACPI_VIDEO || ACPI_VIDEO = n
362 depends on BACKLIGHT_CLASS_DEVICE
368 This is a driver for the IBM and Lenovo ThinkPad laptops. It adds
369 support for Fn-Fx key combinations, Bluetooth control, video
370 output switching, ThinkLight control, UltraBay eject and more.
371 For more information about this driver see
372 <file:Documentation/laptops/thinkpad-acpi.txt> and
373 <http://ibm-acpi.sf.net/> .
375 This driver was formerly known as ibm-acpi.
377 Extra functionality will be available if the rfkill (CONFIG_RFKILL)
378 and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
379 Note that if you want ThinkPad-ACPI to be built-in instead of
380 modular, ALSA and rfkill will also have to be built-in.
382 If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.
384 config THINKPAD_ACPI_ALSA_SUPPORT
385 bool "Console audio control ALSA interface"
386 depends on THINKPAD_ACPI
388 depends on SND = y || THINKPAD_ACPI = SND
391 Enables monitoring of the built-in console audio output control
392 (headphone and speakers), which is operated by the mute and (in
393 some ThinkPad models) volume hotkeys.
395 If this option is enabled, ThinkPad-ACPI will export an ALSA card
396 with a single read-only mixer control, which should be used for
397 on-screen-display feedback purposes by the Desktop Environment.
399 Optionally, the driver will also allow software control (the
400 ALSA mixer will be made read-write). Please refer to the driver
401 documentation for details.
403 All IBM models have both volume and mute control. Newer Lenovo
404 models only have mute control (the volume hotkeys are just normal
405 keys and volume control is done through the main HDA mixer).
407 config THINKPAD_ACPI_DEBUGFACILITIES
408 bool "Maintainer debug facilities"
409 depends on THINKPAD_ACPI

418 config THINKPAD_ACPI_DEBUG
419 bool "Verbose debug mode"
420 depends on THINKPAD_ACPI
423 Enables extra debugging information, at the expense of a slightly

426 If you are not sure, say N here.
428 config THINKPAD_ACPI_UNSAFE_LEDS
429 bool "Allow control of important LEDs (unsafe)"
430 depends on THINKPAD_ACPI
433 Overriding LED state on ThinkPads can mask important
434 firmware alerts (like critical battery condition), or misled
435 the user into damaging the hardware (undocking or ejecting
436 the bay while buses are still active), etc.
438 LED control on the ThinkPad is write-only (with very few
439 exceptions on very ancient models), which makes it
440 impossible to know beforehand if important information will
441 be lost when one changes LED state.
443 Users that know what they are doing can enable this option
444 and the driver will allow control of every LED, including
445 the ones on the dock stations.
447 Never enable this option on a distribution kernel.
449 Say N here, unless you are building a kernel for your own
450 use, and need to control the important firmware LEDs.
452 config THINKPAD_ACPI_VIDEO
453 bool "Video output control support"
454 depends on THINKPAD_ACPI
457 Allows the thinkpad_acpi driver to provide an interface to control
458 the various video output ports.
460 This feature often won't work well, depending on ThinkPad model,
461 display state, video output devices in use, whether there is a X
462 server running, phase of the moon, and the current mood of
463 Schroedinger's cat. If you can use X.org's RandR to control
464 your ThinkPad's video output ports instead of this feature,
465 don't think twice: do it and say N here to save memory and avoid
466 bad interactions with X.org.
468 NOTE: access to this feature is limited to processes with the
469 CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
470 where it interacts badly with X.org.
472 If you are not sure, say Y here but do try to check if you could
473 be using X.org RandR instead.
475 config THINKPAD_ACPI_HOTKEY_POLL
476 bool "Support NVRAM polling for hot keys"
477 depends on THINKPAD_ACPI
480 Some thinkpad models benefit from NVRAM polling to detect a few of
481 the hot key press events. If you know your ThinkPad model does not
482 need to do NVRAM polling to support any of the hot keys you use,
483 unselecting this option will save about 1kB of memory.
485 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
486 unlikely to need NVRAM polling in their latest BIOS versions.
488 NVRAM polling can detect at most the following keys: ThinkPad/Access
489 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
490 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
492 If you are not sure, say Y here. The driver enables polling only if
493 it is strictly necessary to do so.
496 tristate "Thinkpad Hard Drive Active Protection System (hdaps)"
497 depends on INPUT && X86
501 This driver provides support for the IBM Hard Drive Active Protection
502 System (hdaps), which provides an accelerometer and other misc. data.
503 ThinkPads starting with the R50, T41, and X40 are supported. The
504 accelerometer data is readable via sysfs.
506 This driver also provides an absolute input class device, allowing
507 the laptop to act as a pinball machine-esque joystick.
509 If your ThinkPad is not recognized by the driver, please update to latest
510 BIOS. This is especially the case for some R52 ThinkPads.
512 Say Y here if you have an applicable laptop and want to experience
513 the awesome power of hdaps.

597 This driver adds support for the ACPI-WMI (Windows Management
598 Instrumentation) mapper device (PNP0C14) found on some systems.
600 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
601 ACPI firmware to userspace - this is done through various vendor
602 defined methods and data blocks in a PNP0C14 device, which are then
603 made available for userspace to call.
605 The implementation of this in Linux currently only exposes this to
606 other kernel space drivers.
608 This driver is a required dependency to build the firmware specific
609 drivers needed on many machines, including Acer and HP laptops.

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

920 Intel Smart Connect is a technology intended to permit devices to
921 update state by resuming for a short period of time at regular
922 intervals. If a user enables this functionality under Windows and
923 then reboots into Linux, the system may remain configured to resume
924 on suspend. In the absence of any userspace to support it, the system
925 will then remain awake until something triggers another suspend.
927 This driver checks to determine whether the device has Intel Smart
928 Connect enabled, and if so disables it.
