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

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

594 This driver adds support for the ACPI-WMI (Windows Management
595 Instrumentation) mapper device (PNP0C14) found on some systems.
597 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
598 ACPI firmware to userspace - this is done through various vendor
599 defined methods and data blocks in a PNP0C14 device, which are then
600 made available for userspace to call.
602 The implementation of this in Linux currently only exposes this to
603 other kernel space drivers.
605 This driver is a required dependency to build the firmware specific
606 drivers needed on many machines, including Acer and HP laptops.
608 It is safe to enable this driver even if your DSDT doesn't define
609 any ACPI-WMI devices.

650 their lack of a BIOS setup menu and APM support.
652 On these machines, all system configuration is handled through the
653 ACPI. This driver is required for access to controls not covered
654 by the general ACPI drivers, such as LCD brightness, video output,
657 This driver differs from the non-ACPI Toshiba laptop driver (located
658 under "Processor type and features") in several aspects.
659 Configuration is accessed by reading and writing text files in the
660 /proc tree instead of by program interface to /dev. Furthermore, no

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