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

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

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