330 tristate "ThinkPad ACPI Laptop Extras"
333 depends on RFKILL || RFKILL = n
334 select BACKLIGHT_LCD_SUPPORT
335 select BACKLIGHT_CLASS_DEVICE
341 This is a driver for the IBM and Lenovo ThinkPad laptops. It adds
342 support for Fn-Fx key combinations, Bluetooth control, video
343 output switching, ThinkLight control, UltraBay eject and more.
344 For more information about this driver see
345 <file:Documentation/laptops/thinkpad-acpi.txt> and
346 <http://ibm-acpi.sf.net/> .
348 This driver was formerly known as ibm-acpi.
350 Extra functionality will be available if the rfkill (CONFIG_RFKILL)
351 and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
352 Note that if you want ThinkPad-ACPI to be built-in instead of
353 modular, ALSA and rfkill will also have to be built-in.
355 If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.
357 config THINKPAD_ACPI_ALSA_SUPPORT
358 bool "Console audio control ALSA interface"
359 depends on THINKPAD_ACPI
361 depends on SND = y || THINKPAD_ACPI = SND
364 Enables monitoring of the built-in console audio output control
365 (headphone and speakers), which is operated by the mute and (in
366 some ThinkPad models) volume hotkeys.
368 If this option is enabled, ThinkPad-ACPI will export an ALSA card
369 with a single read-only mixer control, which should be used for
370 on-screen-display feedback purposes by the Desktop Environment.
372 Optionally, the driver will also allow software control (the
373 ALSA mixer will be made read-write). Please refer to the driver
374 documentation for details.
376 All IBM models have both volume and mute control. Newer Lenovo
377 models only have mute control (the volume hotkeys are just normal
378 keys and volume control is done through the main HDA mixer).
380 config THINKPAD_ACPI_DEBUGFACILITIES
381 bool "Maintainer debug facilities"
382 depends on THINKPAD_ACPI
385 Enables extra stuff in the thinkpad-acpi which is completely useless
386 for normal use. Read the driver source to find out what it does.
388 Say N here, unless you were told by a kernel maintainer to do
391 config THINKPAD_ACPI_DEBUG
392 bool "Verbose debug mode"
393 depends on THINKPAD_ACPI
396 Enables extra debugging information, at the expense of a slightly
397 increase in driver size.
399 If you are not sure, say N here.
401 config THINKPAD_ACPI_UNSAFE_LEDS
402 bool "Allow control of important LEDs (unsafe)"
403 depends on THINKPAD_ACPI
406 Overriding LED state on ThinkPads can mask important
407 firmware alerts (like critical battery condition), or misled
408 the user into damaging the hardware (undocking or ejecting
409 the bay while buses are still active), etc.
411 LED control on the ThinkPad is write-only (with very few
412 exceptions on very ancient models), which makes it
413 impossible to know beforehand if important information will
414 be lost when one changes LED state.
416 Users that know what they are doing can enable this option
417 and the driver will allow control of every LED, including
418 the ones on the dock stations.
420 Never enable this option on a distribution kernel.
422 Say N here, unless you are building a kernel for your own
423 use, and need to control the important firmware LEDs.
425 config THINKPAD_ACPI_VIDEO
426 bool "Video output control support"
427 depends on THINKPAD_ACPI
430 Allows the thinkpad_acpi driver to provide an interface to control
431 the various video output ports.
433 This feature often won't work well, depending on ThinkPad model,
434 display state, video output devices in use, whether there is a X
435 server running, phase of the moon, and the current mood of
436 Schroedinger's cat. If you can use X.org's RandR to control
437 your ThinkPad's video output ports instead of this feature,
438 don't think twice: do it and say N here to save memory and avoid
439 bad interactions with X.org.
441 NOTE: access to this feature is limited to processes with the
442 CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
443 where it interacts badly with X.org.
445 If you are not sure, say Y here but do try to check if you could
446 be using X.org RandR instead.
448 config THINKPAD_ACPI_HOTKEY_POLL
449 bool "Support NVRAM polling for hot keys"
450 depends on THINKPAD_ACPI
453 Some thinkpad models benefit from NVRAM polling to detect a few of
454 the hot key press events. If you know your ThinkPad model does not
455 need to do NVRAM polling to support any of the hot keys you use,
456 unselecting this option will save about 1kB of memory.
458 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
459 unlikely to need NVRAM polling in their latest BIOS versions.
461 NVRAM polling can detect at most the following keys: ThinkPad/Access
462 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
463 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
465 If you are not sure, say Y here. The driver enables polling only if
466 it is strictly necessary to do so.
469 tristate "Thinkpad Hard Drive Active Protection System (hdaps)"
470 depends on INPUT && X86
474 This driver provides support for the IBM Hard Drive Active Protection
475 System (hdaps), which provides an accelerometer and other misc. data.
476 ThinkPads starting with the R50, T41, and X40 are supported. The
477 accelerometer data is readable via sysfs.
479 This driver also provides an absolute input class device, allowing
480 the laptop to act as a pinball machine-esque joystick.
482 If your ThinkPad is not recognized by the driver, please update to latest
483 BIOS. This is especially the case for some R52 ThinkPads.
485 Say Y here if you have an applicable laptop and want to experience
486 the awesome power of hdaps.

561 If you have an ACPI-WMI compatible Eee PC laptop (>= 1000), say Y or M
568 This driver adds support for the ACPI-WMI (Windows Management
569 Instrumentation) mapper device (PNP0C14) found on some systems.
571 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
572 ACPI firmware to userspace - this is done through various vendor
573 defined methods and data blocks in a PNP0C14 device, which are then
574 made available for userspace to call.
576 The implementation of this in Linux currently only exposes this to
577 other kernel space drivers.
579 This driver is a required dependency to build the firmware specific
580 drivers needed on many machines, including Acer and HP laptops.
582 It is safe to enable this driver even if your DSDT doesn't define
583 any ACPI-WMI devices.

619 select INPUT_SPARSEKMAP
621 This driver adds support for access to certain system settings
622 on "legacy free" Toshiba laptops. These laptops can be recognized by
623 their lack of a BIOS setup menu and APM support.
625 On these machines, all system configuration is handled through the
626 ACPI. This driver is required for access to controls not covered
627 by the general ACPI drivers, such as LCD brightness, video output,
630 This driver differs from the non-ACPI Toshiba laptop driver (located
631 under "Processor type and features") in several aspects.
632 Configuration is accessed by reading and writing text files in the
633 /proc tree instead of by program interface to /dev. Furthermore, no
634 power management functions are exposed, as those are handled by the
635 general ACPI drivers.

744 This option provides a means to manipulate Isolated Memory Regions.
745 IMRs are a set of registers that define read and write access masks
746 to prohibit certain system agents from accessing memory with 1 KiB
749 IMRs make it possible to control read/write access to an address
750 by hardware agents inside the SoC. Read and write masks can be
753 - Dirty CPU snoop (write only)

771 not receive CPU-generated SMIs for recoverable errors. Use of this
772 feature without proper support may void your hardware warranty.
774 If the proper BIOS support is found the driver will load and create

872 intervals. If a user enables this functionality under Windows and
873 then reboots into Linux, the system may remain configured to resume

878 Connect enabled, and if so disables it.
