382 depends on RFKILL || RFKILL = n
383 depends on ACPI_VIDEO || ACPI_VIDEO = n
384 depends on BACKLIGHT_CLASS_DEVICE
390 This is a driver for the IBM and Lenovo ThinkPad laptops. It adds
391 support for Fn-Fx key combinations, Bluetooth control, video
392 output switching, ThinkLight control, UltraBay eject and more.
393 For more information about this driver see
394 <file:Documentation/laptops/thinkpad-acpi.txt> and
395 <http://ibm-acpi.sf.net/> .
397 This driver was formerly known as ibm-acpi.
399 Extra functionality will be available if the rfkill (CONFIG_RFKILL)
400 and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
401 Note that if you want ThinkPad-ACPI to be built-in instead of
402 modular, ALSA and rfkill will also have to be built-in.
404 If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.
406 config THINKPAD_ACPI_ALSA_SUPPORT
407 bool "Console audio control ALSA interface"
408 depends on THINKPAD_ACPI
410 depends on SND = y || THINKPAD_ACPI = SND
413 Enables monitoring of the built-in console audio output control
414 (headphone and speakers), which is operated by the mute and (in
415 some ThinkPad models) volume hotkeys.
417 If this option is enabled, ThinkPad-ACPI will export an ALSA card
418 with a single read-only mixer control, which should be used for
419 on-screen-display feedback purposes by the Desktop Environment.
421 Optionally, the driver will also allow software control (the
422 ALSA mixer will be made read-write). Please refer to the driver
423 documentation for details.
425 All IBM models have both volume and mute control. Newer Lenovo
426 models only have mute control (the volume hotkeys are just normal
427 keys and volume control is done through the main HDA mixer).
429 config THINKPAD_ACPI_DEBUGFACILITIES
430 bool "Maintainer debug facilities"
431 depends on THINKPAD_ACPI
434 Enables extra stuff in the thinkpad-acpi which is completely useless
435 for normal use. Read the driver source to find out what it does.
437 Say N here, unless you were told by a kernel maintainer to do
440 config THINKPAD_ACPI_DEBUG
441 bool "Verbose debug mode"
442 depends on THINKPAD_ACPI
445 Enables extra debugging information, at the expense of a slightly
446 increase in driver size.
448 If you are not sure, say N here.
450 config THINKPAD_ACPI_UNSAFE_LEDS
451 bool "Allow control of important LEDs (unsafe)"
452 depends on THINKPAD_ACPI
455 Overriding LED state on ThinkPads can mask important
456 firmware alerts (like critical battery condition), or misled
457 the user into damaging the hardware (undocking or ejecting
458 the bay while buses are still active), etc.
460 LED control on the ThinkPad is write-only (with very few
461 exceptions on very ancient models), which makes it
462 impossible to know beforehand if important information will
463 be lost when one changes LED state.
465 Users that know what they are doing can enable this option
466 and the driver will allow control of every LED, including
467 the ones on the dock stations.
469 Never enable this option on a distribution kernel.
471 Say N here, unless you are building a kernel for your own
472 use, and need to control the important firmware LEDs.
474 config THINKPAD_ACPI_VIDEO
475 bool "Video output control support"
476 depends on THINKPAD_ACPI
479 Allows the thinkpad_acpi driver to provide an interface to control
480 the various video output ports.
482 This feature often won't work well, depending on ThinkPad model,
483 display state, video output devices in use, whether there is a X
484 server running, phase of the moon, and the current mood of
485 Schroedinger's cat. If you can use X.org's RandR to control
486 your ThinkPad's video output ports instead of this feature,
487 don't think twice: do it and say N here to save memory and avoid
488 bad interactions with X.org.
490 NOTE: access to this feature is limited to processes with the
491 CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
492 where it interacts badly with X.org.
494 If you are not sure, say Y here but do try to check if you could
495 be using X.org RandR instead.
497 config THINKPAD_ACPI_HOTKEY_POLL
498 bool "Support NVRAM polling for hot keys"
499 depends on THINKPAD_ACPI
502 Some thinkpad models benefit from NVRAM polling to detect a few of
503 the hot key press events. If you know your ThinkPad model does not
504 need to do NVRAM polling to support any of the hot keys you use,
505 unselecting this option will save about 1kB of memory.
507 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
508 unlikely to need NVRAM polling in their latest BIOS versions.
510 NVRAM polling can detect at most the following keys: ThinkPad/Access
511 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
512 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
514 If you are not sure, say Y here. The driver enables polling only if
515 it is strictly necessary to do so.
518 tristate "Thinkpad Hard Drive Active Protection System (hdaps)"
523 This driver provides support for the IBM Hard Drive Active Protection
524 System (hdaps), which provides an accelerometer and other misc. data.
525 ThinkPads starting with the R50, T41, and X40 are supported. The
526 accelerometer data is readable via sysfs.
528 This driver also provides an absolute input class device, allowing
529 the laptop to act as a pinball machine-esque joystick.
531 If your ThinkPad is not recognized by the driver, please update to latest
532 BIOS. This is especially the case for some R52 ThinkPads.
534 Say Y here if you have an applicable laptop and want to experience
535 the awesome power of hdaps.

625 Say Y or M here if you have an ASUS notebook with an airplane mode
628 If you choose to compile this driver as a module the module will be
629 called asus-wireless.
635 This driver adds support for the ACPI-WMI (Windows Management
636 Instrumentation) mapper device (PNP0C14) found on some systems.
638 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
639 ACPI firmware to userspace - this is done through various vendor
640 defined methods and data blocks in a PNP0C14 device, which are then
641 made available for userspace to call.
643 The implementation of this in Linux currently only exposes this to
644 other kernel space drivers.
646 This driver is a required dependency to build the firmware specific
647 drivers needed on many machines, including Acer and HP laptops.
649 It is safe to enable this driver even if your DSDT doesn't define
650 any ACPI-WMI devices.

692 their lack of a BIOS setup menu and APM support.
694 On these machines, all system configuration is handled through the
695 ACPI. This driver is required for access to controls not covered
696 by the general ACPI drivers, such as LCD brightness, video output,
699 This driver differs from the non-ACPI Toshiba laptop driver (located
700 under "Processor type and features") in several aspects.
701 Configuration is accessed by reading and writing text files in the
702 /proc tree instead of by program interface to /dev. Furthermore, no
703 power management functions are exposed, as those are handled by the
704 general ACPI drivers.

856 This option provides a means to manipulate Isolated Memory Regions.
857 IMRs are a set of registers that define read and write access masks
858 to prohibit certain system agents from accessing memory with 1 KiB
861 IMRs make it possible to control read/write access to an address
862 by hardware agents inside the SoC. Read and write masks can be

983 equipped with Intel's Rapid Start Technology. When put in an ACPI
984 sleep state, these devices will wake after either a configured
985 timeout or when the system battery reaches a critical state,
986 automatically copying memory contents to disk. On resume, the
987 firmware will copy the memory contents back to RAM and resume the OS
990 config INTEL_SMARTCONNECT
991 tristate "Intel Smart Connect disabling driver"
994 Intel Smart Connect is a technology intended to permit devices to
995 update state by resuming for a short period of time at regular
996 intervals. If a user enables this functionality under Windows and
997 then reboots into Linux, the system may remain configured to resume
998 on suspend. In the absence of any userspace to support it, the system
999 will then remain awake until something triggers another suspend.
