504 For more information about this driver see

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

541 bool "Maintainer debug facilities"
542 depends on THINKPAD_ACPI
544 Enables extra stuff in the thinkpad-acpi which is completely useless

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

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

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