357 depends on RFKILL || RFKILL = n
358 depends on ACPI_VIDEO || ACPI_VIDEO = n
359 depends on BACKLIGHT_CLASS_DEVICE
365 This is a driver for the IBM and Lenovo ThinkPad laptops. It adds
366 support for Fn-Fx key combinations, Bluetooth control, video
367 output switching, ThinkLight control, UltraBay eject and more.
368 For more information about this driver see
369 <file:Documentation/laptops/thinkpad-acpi.txt> and
370 <http://ibm-acpi.sf.net/> .
372 This driver was formerly known as ibm-acpi.
374 Extra functionality will be available if the rfkill (CONFIG_RFKILL)
375 and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
376 Note that if you want ThinkPad-ACPI to be built-in instead of
377 modular, ALSA and rfkill will also have to be built-in.
379 If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.
381 config THINKPAD_ACPI_ALSA_SUPPORT
382 bool "Console audio control ALSA interface"
383 depends on THINKPAD_ACPI
385 depends on SND = y || THINKPAD_ACPI = SND
388 Enables monitoring of the built-in console audio output control
389 (headphone and speakers), which is operated by the mute and (in
390 some ThinkPad models) volume hotkeys.
392 If this option is enabled, ThinkPad-ACPI will export an ALSA card
393 with a single read-only mixer control, which should be used for
394 on-screen-display feedback purposes by the Desktop Environment.
396 Optionally, the driver will also allow software control (the
397 ALSA mixer will be made read-write). Please refer to the driver
398 documentation for details.
400 All IBM models have both volume and mute control. Newer Lenovo
401 models only have mute control (the volume hotkeys are just normal
402 keys and volume control is done through the main HDA mixer).
404 config THINKPAD_ACPI_DEBUGFACILITIES
405 bool "Maintainer debug facilities"
406 depends on THINKPAD_ACPI
409 Enables extra stuff in the thinkpad-acpi which is completely useless
410 for normal use. Read the driver source to find out what it does.
412 Say N here, unless you were told by a kernel maintainer to do
415 config THINKPAD_ACPI_DEBUG
416 bool "Verbose debug mode"
417 depends on THINKPAD_ACPI
420 Enables extra debugging information, at the expense of a slightly
421 increase in driver size.
423 If you are not sure, say N here.
425 config THINKPAD_ACPI_UNSAFE_LEDS
426 bool "Allow control of important LEDs (unsafe)"
427 depends on THINKPAD_ACPI
430 Overriding LED state on ThinkPads can mask important
431 firmware alerts (like critical battery condition), or misled
432 the user into damaging the hardware (undocking or ejecting
433 the bay while buses are still active), etc.
435 LED control on the ThinkPad is write-only (with very few
436 exceptions on very ancient models), which makes it
437 impossible to know beforehand if important information will
438 be lost when one changes LED state.
440 Users that know what they are doing can enable this option
441 and the driver will allow control of every LED, including
442 the ones on the dock stations.
444 Never enable this option on a distribution kernel.
446 Say N here, unless you are building a kernel for your own
447 use, and need to control the important firmware LEDs.
449 config THINKPAD_ACPI_VIDEO
450 bool "Video output control support"
451 depends on THINKPAD_ACPI
454 Allows the thinkpad_acpi driver to provide an interface to control
455 the various video output ports.
457 This feature often won't work well, depending on ThinkPad model,
458 display state, video output devices in use, whether there is a X
459 server running, phase of the moon, and the current mood of
460 Schroedinger's cat. If you can use X.org's RandR to control
461 your ThinkPad's video output ports instead of this feature,
462 don't think twice: do it and say N here to save memory and avoid
463 bad interactions with X.org.
465 NOTE: access to this feature is limited to processes with the
466 CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
467 where it interacts badly with X.org.
469 If you are not sure, say Y here but do try to check if you could
470 be using X.org RandR instead.
472 config THINKPAD_ACPI_HOTKEY_POLL
473 bool "Support NVRAM polling for hot keys"
474 depends on THINKPAD_ACPI
477 Some thinkpad models benefit from NVRAM polling to detect a few of
478 the hot key press events. If you know your ThinkPad model does not
479 need to do NVRAM polling to support any of the hot keys you use,
480 unselecting this option will save about 1kB of memory.
482 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
483 unlikely to need NVRAM polling in their latest BIOS versions.
485 NVRAM polling can detect at most the following keys: ThinkPad/Access
486 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
487 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
489 If you are not sure, say Y here. The driver enables polling only if
490 it is strictly necessary to do so.
493 tristate "Thinkpad Hard Drive Active Protection System (hdaps)"
494 depends on INPUT && X86
498 This driver provides support for the IBM Hard Drive Active Protection
499 System (hdaps), which provides an accelerometer and other misc. data.
500 ThinkPads starting with the R50, T41, and X40 are supported. The
501 accelerometer data is readable via sysfs.
503 This driver also provides an absolute input class device, allowing
504 the laptop to act as a pinball machine-esque joystick.
506 If your ThinkPad is not recognized by the driver, please update to latest
507 BIOS. This is especially the case for some R52 ThinkPads.
509 Say Y here if you have an applicable laptop and want to experience
510 the awesome power of hdaps.

586 If you have an ACPI-WMI compatible Eee PC laptop (>= 1000), say Y or M
593 This driver adds support for the ACPI-WMI (Windows Management
594 Instrumentation) mapper device (PNP0C14) found on some systems.
596 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
597 ACPI firmware to userspace - this is done through various vendor
598 defined methods and data blocks in a PNP0C14 device, which are then
599 made available for userspace to call.
601 The implementation of this in Linux currently only exposes this to
602 other kernel space drivers.
604 This driver is a required dependency to build the firmware specific
605 drivers needed on many machines, including Acer and HP laptops.
607 It is safe to enable this driver even if your DSDT doesn't define
608 any ACPI-WMI devices.

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

856 Intel Oaktrail platform need this driver to provide interfaces to
857 enable/disable the Camera, WiFi, BT etc. devices. If in doubt, say Y
858 here; it will only load on supported platforms.
861 tristate "Samsung Q10 Extras"
863 select BACKLIGHT_CLASS_DEVICE
865 This driver provides support for backlight control on Samsung Q10
866 and related laptops, including Dell Latitude X200.
869 tristate "Apple Gmux Driver"
872 depends on BACKLIGHT_CLASS_DEVICE
873 depends on BACKLIGHT_APPLE=n || BACKLIGHT_APPLE
874 depends on ACPI_VIDEO=n || ACPI_VIDEO
876 This driver provides support for the gmux device found on many
877 Apple laptops, which controls the display mux for the hybrid
878 graphics as well as the backlight. Currently only backlight
879 control is supported by the driver.
882 tristate "Intel Rapid Start Technology Driver"
885 This driver provides support for modifying paramaters on systems
886 equipped with Intel's Rapid Start Technology. When put in an ACPI
887 sleep state, these devices will wake after either a configured
888 timeout or when the system battery reaches a critical state,
889 automatically copying memory contents to disk. On resume, the
890 firmware will copy the memory contents back to RAM and resume the OS
893 config INTEL_SMARTCONNECT
894 tristate "Intel Smart Connect disabling driver"
897 Intel Smart Connect is a technology intended to permit devices to
898 update state by resuming for a short period of time at regular
899 intervals. If a user enables this functionality under Windows and
900 then reboots into Linux, the system may remain configured to resume
901 on suspend. In the absence of any userspace to support it, the system
902 will then remain awake until something triggers another suspend.
904 This driver checks to determine whether the device has Intel Smart
905 Connect enabled, and if so disables it.
908 tristate "pvpanic device support"
911 This driver provides support for the pvpanic device. pvpanic is
912 a paravirtualized device provided by QEMU; it lets a virtual machine
913 (guest) communicate panic events to the host.
916 tristate "Intel PMC IPC Driver"
918 This driver provides support for PMC control on some Intel platforms.
919 The PMC is an ARC processor which defines IPC commands for communication
920 with other entities in the CPU.
