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

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

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