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

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

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

867 graphics as well as the backlight. Currently only backlight
868 control is supported by the driver.
871 tristate "Intel Rapid Start Technology Driver"
874 This driver provides support for modifying paramaters on systems
875 equipped with Intel's Rapid Start Technology. When put in an ACPI
876 sleep state, these devices will wake after either a configured
877 timeout or when the system battery reaches a critical state,
878 automatically copying memory contents to disk. On resume, the
879 firmware will copy the memory contents back to RAM and resume the OS
882 config INTEL_SMARTCONNECT
883 tristate "Intel Smart Connect disabling driver"
886 Intel Smart Connect is a technology intended to permit devices to
887 update state by resuming for a short period of time at regular
888 intervals. If a user enables this functionality under Windows and
889 then reboots into Linux, the system may remain configured to resume
890 on suspend. In the absence of any userspace to support it, the system
891 will then remain awake until something triggers another suspend.
893 This driver checks to determine whether the device has Intel Smart
894 Connect enabled, and if so disables it.
897 tristate "pvpanic device support"
900 This driver provides support for the pvpanic device. pvpanic is
901 a paravirtualized device provided by QEMU; it lets a virtual machine
902 (guest) communicate panic events to the host.
905 tristate "Intel PMC IPC Driver"
907 This driver provides support for PMC control on some Intel platforms.
908 The PMC is an ARC processor which defines IPC commands for communication
909 with other entities in the CPU.
