483 This is a driver for the IBM and Lenovo ThinkPad laptops. It adds

485 output switching, ThinkLight control, UltraBay eject and more.
486 For more information about this driver see
487 <file:Documentation/laptops/thinkpad-acpi.txt> and

490 This driver was formerly known as ibm-acpi.
492 Extra functionality will be available if the rfkill (CONFIG_RFKILL)
493 and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
494 Note that if you want ThinkPad-ACPI to be built-in instead of
495 modular, ALSA and rfkill will also have to be built-in.
497 If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.
499 config THINKPAD_ACPI_ALSA_SUPPORT
500 bool "Console audio control ALSA interface"
501 depends on THINKPAD_ACPI
503 depends on SND = y || THINKPAD_ACPI = SND
506 Enables monitoring of the built-in console audio output control
507 (headphone and speakers), which is operated by the mute and (in
508 some ThinkPad models) volume hotkeys.
510 If this option is enabled, ThinkPad-ACPI will export an ALSA card
511 with a single read-only mixer control, which should be used for
512 on-screen-display feedback purposes by the Desktop Environment.
514 Optionally, the driver will also allow software control (the
515 ALSA mixer will be made read-write). Please refer to the driver
516 documentation for details.
518 All IBM models have both volume and mute control. Newer Lenovo
519 models only have mute control (the volume hotkeys are just normal
520 keys and volume control is done through the main HDA mixer).
522 config THINKPAD_ACPI_DEBUGFACILITIES
523 bool "Maintainer debug facilities"
524 depends on THINKPAD_ACPI
526 Enables extra stuff in the thinkpad-acpi which is completely useless

529 Say N here, unless you were told by a kernel maintainer to do
532 config THINKPAD_ACPI_DEBUG
533 bool "Verbose debug mode"
534 depends on THINKPAD_ACPI
536 Enables extra debugging information, at the expense of a slightly
537 increase in driver size.
539 If you are not sure, say N here.
541 config THINKPAD_ACPI_UNSAFE_LEDS
542 bool "Allow control of important LEDs (unsafe)"
543 depends on THINKPAD_ACPI
545 Overriding LED state on ThinkPads can mask important
546 firmware alerts (like critical battery condition), or misled
547 the user into damaging the hardware (undocking or ejecting
548 the bay while buses are still active), etc.
550 LED control on the ThinkPad is write-only (with very few
551 exceptions on very ancient models), which makes it
552 impossible to know beforehand if important information will
553 be lost when one changes LED state.
555 Users that know what they are doing can enable this option
556 and the driver will allow control of every LED, including
557 the ones on the dock stations.
559 Never enable this option on a distribution kernel.
561 Say N here, unless you are building a kernel for your own
562 use, and need to control the important firmware LEDs.
564 config THINKPAD_ACPI_VIDEO
565 bool "Video output control support"
566 depends on THINKPAD_ACPI
569 Allows the thinkpad_acpi driver to provide an interface to control
570 the various video output ports.
572 This feature often won't work well, depending on ThinkPad model,
573 display state, video output devices in use, whether there is a X
574 server running, phase of the moon, and the current mood of
575 Schroedinger's cat. If you can use X.org's RandR to control
576 your ThinkPad's video output ports instead of this feature,
577 don't think twice: do it and say N here to save memory and avoid
578 bad interactions with X.org.
580 NOTE: access to this feature is limited to processes with the
581 CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
582 where it interacts badly with X.org.
584 If you are not sure, say Y here but do try to check if you could
585 be using X.org RandR instead.
587 config THINKPAD_ACPI_HOTKEY_POLL
588 bool "Support NVRAM polling for hot keys"
589 depends on THINKPAD_ACPI
592 Some thinkpad models benefit from NVRAM polling to detect a few of
593 the hot key press events. If you know your ThinkPad model does not
594 need to do NVRAM polling to support any of the hot keys you use,
595 unselecting this option will save about 1kB of memory.
597 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
598 unlikely to need NVRAM polling in their latest BIOS versions.
600 NVRAM polling can detect at most the following keys: ThinkPad/Access
601 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
602 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
604 If you are not sure, say Y here. The driver enables polling only if
605 it is strictly necessary to do so.
608 tristate "Thinkpad Hard Drive Active Protection System (hdaps)"
612 This driver provides support for the IBM Hard Drive Active Protection
613 System (hdaps), which provides an accelerometer and other misc. data.
614 ThinkPads starting with the R50, T41, and X40 are supported. The
615 accelerometer data is readable via sysfs.
617 This driver also provides an absolute input class device, allowing
618 the laptop to act as a pinball machine-esque joystick.
620 If your ThinkPad is not recognized by the driver, please update to latest
621 BIOS. This is especially the case for some R52 ThinkPads.
623 Say Y here if you have an applicable laptop and want to experience
624 the awesome power of hdaps.

718 called asus-wireless.
724 This driver adds support for the ACPI-WMI (Windows Management
725 Instrumentation) mapper device (PNP0C14) found on some systems.
727 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
728 ACPI firmware to userspace - this is done through various vendor
729 defined methods and data blocks in a PNP0C14 device, which are then
730 made available for userspace to call.
732 The implementation of this in Linux currently only exposes this to
733 other kernel space drivers.
735 This driver is a required dependency to build the firmware specific

815 their lack of a BIOS setup menu and APM support.
817 On these machines, all system configuration is handled through the
818 ACPI. This driver is required for access to controls not covered
819 by the general ACPI drivers, such as LCD brightness, video output,
822 This driver differs from the non-ACPI Toshiba laptop driver (located
823 under "Processor type and features") in several aspects.
824 Configuration is accessed by reading and writing text files in the
825 /proc tree instead of by program interface to /dev. Furthermore, no
