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

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

632 on "legacy free" Toshiba laptops. These laptops can be recognized by
633 their lack of a BIOS setup menu and APM support.
635 On these machines, all system configuration is handled through the
636 ACPI. This driver is required for access to controls not covered
637 by the general ACPI drivers, such as LCD brightness, video output,
640 This driver differs from the non-ACPI Toshiba laptop driver (located
641 under "Processor type and features") in several aspects.
642 Configuration is accessed by reading and writing text files in the
643 /proc tree instead of by program interface to /dev. Furthermore, no
644 power management functions are exposed, as those are handled by the
645 general ACPI drivers.

755 IMRs are a set of registers that define read and write access masks
756 to prohibit certain system agents from accessing memory with 1 KiB
759 IMRs make it possible to control read/write access to an address
760 by hardware agents inside the SoC. Read and write masks can be

857 depends on BACKLIGHT_APPLE=n || BACKLIGHT_APPLE
858 depends on ACPI_VIDEO=n || ACPI_VIDEO
860 This driver provides support for the gmux device found on many
861 Apple laptops, which controls the display mux for the hybrid
862 graphics as well as the backlight. Currently only backlight
863 control is supported by the driver.
866 tristate "Intel Rapid Start Technology Driver"
869 This driver provides support for modifying paramaters on systems
870 equipped with Intel's Rapid Start Technology. When put in an ACPI
871 sleep state, these devices will wake after either a configured
872 timeout or when the system battery reaches a critical state,
873 automatically copying memory contents to disk. On resume, the
874 firmware will copy the memory contents back to RAM and resume the OS
877 config INTEL_SMARTCONNECT
878 tristate "Intel Smart Connect disabling driver"
881 Intel Smart Connect is a technology intended to permit devices to
882 update state by resuming for a short period of time at regular
883 intervals. If a user enables this functionality under Windows and
884 then reboots into Linux, the system may remain configured to resume
885 on suspend. In the absence of any userspace to support it, the system
886 will then remain awake until something triggers another suspend.
888 This driver checks to determine whether the device has Intel Smart
889 Connect enabled, and if so disables it.
892 tristate "pvpanic device support"
895 This driver provides support for the pvpanic device. pvpanic is
896 a paravirtualized device provided by QEMU; it lets a virtual machine
897 (guest) communicate panic events to the host.
