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

540 If you have an ACPI-WMI compatible Eee PC laptop (>= 1000), say Y or M
547 This driver adds support for the ACPI-WMI (Windows Management
548 Instrumentation) mapper device (PNP0C14) found on some systems.
550 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
551 ACPI firmware to userspace - this is done through various vendor
552 defined methods and data blocks in a PNP0C14 device, which are then
553 made available for userspace to call.
555 The implementation of this in Linux currently only exposes this to
556 other kernel space drivers.
558 This driver is a required dependency to build the firmware specific
559 drivers needed on many machines, including Acer and HP laptops.
561 It is safe to enable this driver even if your DSDT doesn't define
562 any ACPI-WMI devices.

599 This driver adds support for access to certain system settings
600 on "legacy free" Toshiba laptops. These laptops can be recognized by
601 their lack of a BIOS setup menu and APM support.
603 On these machines, all system configuration is handled through the
604 ACPI. This driver is required for access to controls not covered
605 by the general ACPI drivers, such as LCD brightness, video output,
608 This driver differs from the non-ACPI Toshiba laptop driver (located
609 under "Processor type and features") in several aspects.
610 Configuration is accessed by reading and writing text files in the
611 /proc tree instead of by program interface to /dev. Furthermore, no
612 power management functions are exposed, as those are handled by the
613 general ACPI drivers.

706 feature without proper support may void your hardware warranty.
708 If the proper BIOS support is found the driver will load and create
