455 For more information about this driver see

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

469 bool "Console audio control ALSA interface"
470 depends on THINKPAD_ACPI

475 Enables monitoring of the built-in console audio output control
476 (headphone and speakers), which is operated by the mute and (in
477 some ThinkPad models) volume hotkeys.
479 If this option is enabled, ThinkPad-ACPI will export an ALSA card
480 with a single read-only mixer control, which should be used for
481 on-screen-display feedback purposes by the Desktop Environment.
483 Optionally, the driver will also allow software control (the
484 ALSA mixer will be made read-write). Please refer to the driver
485 documentation for details.
487 All IBM models have both volume and mute control. Newer Lenovo
488 models only have mute control (the volume hotkeys are just normal
489 keys and volume control is done through the main HDA mixer).

501 config THINKPAD_ACPI_DEBUG
502 bool "Verbose debug mode"

508 If you are not sure, say N here.
510 config THINKPAD_ACPI_UNSAFE_LEDS
511 bool "Allow control of important LEDs (unsafe)"
512 depends on THINKPAD_ACPI
514 Overriding LED state on ThinkPads can mask important
515 firmware alerts (like critical battery condition), or misled
516 the user into damaging the hardware (undocking or ejecting
517 the bay while buses are still active), etc.
519 LED control on the ThinkPad is write-only (with very few
520 exceptions on very ancient models), which makes it
521 impossible to know beforehand if important information will
522 be lost when one changes LED state.
524 Users that know what they are doing can enable this option
525 and the driver will allow control of every LED, including
526 the ones on the dock stations.
528 Never enable this option on a distribution kernel.
530 Say N here, unless you are building a kernel for your own
531 use, and need to control the important firmware LEDs.
533 config THINKPAD_ACPI_VIDEO
534 bool "Video output control support"
535 depends on THINKPAD_ACPI
538 Allows the thinkpad_acpi driver to provide an interface to control
539 the various video output ports.
541 This feature often won't work well, depending on ThinkPad model,
542 display state, video output devices in use, whether there is a X
543 server running, phase of the moon, and the current mood of
544 Schroedinger's cat. If you can use X.org's RandR to control
545 your ThinkPad's video output ports instead of this feature,
546 don't think twice: do it and say N here to save memory and avoid
547 bad interactions with X.org.
549 NOTE: access to this feature is limited to processes with the
550 CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
551 where it interacts badly with X.org.
553 If you are not sure, say Y here but do try to check if you could
554 be using X.org RandR instead.
556 config THINKPAD_ACPI_HOTKEY_POLL
557 bool "Support NVRAM polling for hot keys"
558 depends on THINKPAD_ACPI
561 Some thinkpad models benefit from NVRAM polling to detect a few of
562 the hot key press events. If you know your ThinkPad model does not
563 need to do NVRAM polling to support any of the hot keys you use,
564 unselecting this option will save about 1kB of memory.
566 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
567 unlikely to need NVRAM polling in their latest BIOS versions.
569 NVRAM polling can detect at most the following keys: ThinkPad/Access
570 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
571 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
573 If you are not sure, say Y here. The driver enables polling only if
574 it is strictly necessary to do so.
577 tristate "Thinkpad Hard Drive Active Protection System (hdaps)"
581 This driver provides support for the IBM Hard Drive Active Protection
582 System (hdaps), which provides an accelerometer and other misc. data.
583 ThinkPads starting with the R50, T41, and X40 are supported. The
584 accelerometer data is readable via sysfs.
586 This driver also provides an absolute input class device, allowing
587 the laptop to act as a pinball machine-esque joystick.
589 If your ThinkPad is not recognized by the driver, please update to latest
590 BIOS. This is especially the case for some R52 ThinkPads.

693 This driver adds support for the ACPI-WMI (Windows Management
694 Instrumentation) mapper device (PNP0C14) found on some systems.
696 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
697 ACPI firmware to userspace - this is done through various vendor
698 defined methods and data blocks in a PNP0C14 device, which are then
699 made available for userspace to call.

702 other kernel space drivers.
