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

516 bool "Console audio control ALSA interface"
517 depends on THINKPAD_ACPI

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

549 bool "Verbose debug mode"

552 Enables extra debugging information, at the expense of a slightly

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

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

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

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