511 Extra functionality will be available if the rfkill (CONFIG_RFKILL)
512 and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
513 Note that if you want ThinkPad-ACPI to be built-in instead of
514 modular, ALSA and rfkill will also have to be built-in.

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

551 config THINKPAD_ACPI_DEBUG
552 bool "Verbose debug mode"
553 depends on THINKPAD_ACPI
555 Enables extra debugging information, at the expense of a slightly

558 If you are not sure, say N here.
560 config THINKPAD_ACPI_UNSAFE_LEDS
561 bool "Allow control of important LEDs (unsafe)"
562 depends on THINKPAD_ACPI
564 Overriding LED state on ThinkPads can mask important
565 firmware alerts (like critical battery condition), or misled
566 the user into damaging the hardware (undocking or ejecting
567 the bay while buses are still active), etc.
569 LED control on the ThinkPad is write-only (with very few
570 exceptions on very ancient models), which makes it
571 impossible to know beforehand if important information will
572 be lost when one changes LED state.
574 Users that know what they are doing can enable this option
575 and the driver will allow control of every LED, including
576 the ones on the dock stations.
578 Never enable this option on a distribution kernel.
580 Say N here, unless you are building a kernel for your own
581 use, and need to control the important firmware LEDs.
583 config THINKPAD_ACPI_VIDEO
584 bool "Video output control support"
585 depends on THINKPAD_ACPI
588 Allows the thinkpad_acpi driver to provide an interface to control
589 the various video output ports.
591 This feature often won't work well, depending on ThinkPad model,
592 display state, video output devices in use, whether there is a X
593 server running, phase of the moon, and the current mood of
594 Schroedinger's cat. If you can use X.org's RandR to control
595 your ThinkPad's video output ports instead of this feature,
596 don't think twice: do it and say N here to save memory and avoid
597 bad interactions with X.org.
599 NOTE: access to this feature is limited to processes with the
600 CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
601 where it interacts badly with X.org.
603 If you are not sure, say Y here but do try to check if you could
604 be using X.org RandR instead.
606 config THINKPAD_ACPI_HOTKEY_POLL
607 bool "Support NVRAM polling for hot keys"
608 depends on THINKPAD_ACPI
611 Some thinkpad models benefit from NVRAM polling to detect a few of
612 the hot key press events. If you know your ThinkPad model does not
613 need to do NVRAM polling to support any of the hot keys you use,
614 unselecting this option will save about 1kB of memory.
616 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
617 unlikely to need NVRAM polling in their latest BIOS versions.
619 NVRAM polling can detect at most the following keys: ThinkPad/Access
620 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
621 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
623 If you are not sure, say Y here. The driver enables polling only if
624 it is strictly necessary to do so.

632 System (hdaps), which provides an accelerometer and other misc. data.
633 ThinkPads starting with the R50, T41, and X40 are supported. The
634 accelerometer data is readable via sysfs.
636 This driver also provides an absolute input class device, allowing
637 the laptop to act as a pinball machine-esque joystick.
639 If your ThinkPad is not recognized by the driver, please update to latest
640 BIOS. This is especially the case for some R52 ThinkPads.

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

834 their lack of a BIOS setup menu and APM support.
836 On these machines, all system configuration is handled through the
837 ACPI. This driver is required for access to controls not covered
838 by the general ACPI drivers, such as LCD brightness, video output,
841 This driver differs from the non-ACPI Toshiba laptop driver (located

843 Configuration is accessed by reading and writing text files in the
844 /proc tree instead of by program interface to /dev. Furthermore, no
