505 This driver was formerly known as ibm-acpi.
507 Extra functionality will be available if the rfkill (CONFIG_RFKILL)
508 and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
509 Note that if you want ThinkPad-ACPI to be built-in instead of
510 modular, ALSA and rfkill will also have to be built-in.

515 bool "Console audio control ALSA interface"
516 depends on THINKPAD_ACPI
518 depends on SND = y || THINKPAD_ACPI = SND
521 Enables monitoring of the built-in console audio output control
522 (headphone and speakers), which is operated by the mute and (in
523 some ThinkPad models) volume hotkeys.
525 If this option is enabled, ThinkPad-ACPI will export an ALSA card
526 with a single read-only mixer control, which should be used for
527 on-screen-display feedback purposes by the Desktop Environment.
529 Optionally, the driver will also allow software control (the
530 ALSA mixer will be made read-write). Please refer to the driver
531 documentation for details.
533 All IBM models have both volume and mute control. Newer Lenovo
534 models only have mute control (the volume hotkeys are just normal
535 keys and volume control is done through the main HDA mixer).

548 bool "Verbose debug mode"

554 If you are not sure, say N here.
556 config THINKPAD_ACPI_UNSAFE_LEDS
557 bool "Allow control of important LEDs (unsafe)"
558 depends on THINKPAD_ACPI
560 Overriding LED state on ThinkPads can mask important
561 firmware alerts (like critical battery condition), or misled
562 the user into damaging the hardware (undocking or ejecting
563 the bay while buses are still active), etc.
565 LED control on the ThinkPad is write-only (with very few
566 exceptions on very ancient models), which makes it
567 impossible to know beforehand if important information will
568 be lost when one changes LED state.
570 Users that know what they are doing can enable this option
571 and the driver will allow control of every LED, including
572 the ones on the dock stations.
574 Never enable this option on a distribution kernel.
576 Say N here, unless you are building a kernel for your own
577 use, and need to control the important firmware LEDs.

580 bool "Video output control support"
581 depends on THINKPAD_ACPI
584 Allows the thinkpad_acpi driver to provide an interface to control
585 the various video output ports.
587 This feature often won't work well, depending on ThinkPad model,
588 display state, video output devices in use, whether there is a X
589 server running, phase of the moon, and the current mood of
590 Schroedinger's cat. If you can use X.org's RandR to control
591 your ThinkPad's video output ports instead of this feature,
592 don't think twice: do it and say N here to save memory and avoid
593 bad interactions with X.org.
595 NOTE: access to this feature is limited to processes with the
596 CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
597 where it interacts badly with X.org.
599 If you are not sure, say Y here but do try to check if you could
600 be using X.org RandR instead.
602 config THINKPAD_ACPI_HOTKEY_POLL
603 bool "Support NVRAM polling for hot keys"
604 depends on THINKPAD_ACPI
607 Some thinkpad models benefit from NVRAM polling to detect a few of
608 the hot key press events. If you know your ThinkPad model does not
609 need to do NVRAM polling to support any of the hot keys you use,
610 unselecting this option will save about 1kB of memory.
612 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
613 unlikely to need NVRAM polling in their latest BIOS versions.
615 NVRAM polling can detect at most the following keys: ThinkPad/Access
616 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
617 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
619 If you are not sure, say Y here. The driver enables polling only if
620 it is strictly necessary to do so.

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.

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

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