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

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

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