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

500 For more information about this driver see
501 <file:Documentation/laptops/thinkpad-acpi.txt> and

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

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

638 the awesome power of hdaps.

732 called asus-wireless.
738 This driver adds support for the ACPI-WMI (Windows Management
739 Instrumentation) mapper device (PNP0C14) found on some systems.
741 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
742 ACPI firmware to userspace - this is done through various vendor
743 defined methods and data blocks in a PNP0C14 device, which are then
744 made available for userspace to call.
746 The implementation of this in Linux currently only exposes this to
747 other kernel space drivers.
749 This driver is a required dependency to build the firmware specific

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