285 tristate "Lenovo IdeaPad Laptop Extras"
287 depends on RFKILL && INPUT
288 select INPUT_SPARSEKMAP
290 This is a driver for the rfkill switches on Lenovo IdeaPad netbooks.
293 tristate "ThinkPad ACPI Laptop Extras"
296 depends on RFKILL || RFKILL = n
297 select BACKLIGHT_LCD_SUPPORT
298 select BACKLIGHT_CLASS_DEVICE
304 This is a driver for the IBM and Lenovo ThinkPad laptops. It adds
305 support for Fn-Fx key combinations, Bluetooth control, video
306 output switching, ThinkLight control, UltraBay eject and more.
307 For more information about this driver see
308 <file:Documentation/laptops/thinkpad-acpi.txt> and
309 <http://ibm-acpi.sf.net/> .
311 This driver was formerly known as ibm-acpi.
313 Extra functionality will be available if the rfkill (CONFIG_RFKILL)
314 and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
315 Note that if you want ThinkPad-ACPI to be built-in instead of
316 modular, ALSA and rfkill will also have to be built-in.
318 If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.
320 config THINKPAD_ACPI_ALSA_SUPPORT
321 bool "Console audio control ALSA interface"
322 depends on THINKPAD_ACPI
324 depends on SND = y || THINKPAD_ACPI = SND
327 Enables monitoring of the built-in console audio output control
328 (headphone and speakers), which is operated by the mute and (in
329 some ThinkPad models) volume hotkeys.
331 If this option is enabled, ThinkPad-ACPI will export an ALSA card
332 with a single read-only mixer control, which should be used for
333 on-screen-display feedback purposes by the Desktop Environment.
335 Optionally, the driver will also allow software control (the
336 ALSA mixer will be made read-write). Please refer to the driver
337 documentation for details.
339 All IBM models have both volume and mute control. Newer Lenovo
340 models only have mute control (the volume hotkeys are just normal
341 keys and volume control is done through the main HDA mixer).
343 config THINKPAD_ACPI_DEBUGFACILITIES
344 bool "Maintainer debug facilities"
345 depends on THINKPAD_ACPI
348 Enables extra stuff in the thinkpad-acpi which is completely useless
349 for normal use. Read the driver source to find out what it does.
351 Say N here, unless you were told by a kernel maintainer to do
354 config THINKPAD_ACPI_DEBUG
355 bool "Verbose debug mode"
356 depends on THINKPAD_ACPI
359 Enables extra debugging information, at the expense of a slightly
360 increase in driver size.
362 If you are not sure, say N here.
364 config THINKPAD_ACPI_UNSAFE_LEDS
365 bool "Allow control of important LEDs (unsafe)"
366 depends on THINKPAD_ACPI
369 Overriding LED state on ThinkPads can mask important
370 firmware alerts (like critical battery condition), or misled
371 the user into damaging the hardware (undocking or ejecting
372 the bay while buses are still active), etc.
374 LED control on the ThinkPad is write-only (with very few
375 exceptions on very ancient models), which makes it
376 impossible to know beforehand if important information will
377 be lost when one changes LED state.
379 Users that know what they are doing can enable this option
380 and the driver will allow control of every LED, including
381 the ones on the dock stations.
383 Never enable this option on a distribution kernel.
385 Say N here, unless you are building a kernel for your own
386 use, and need to control the important firmware LEDs.
388 config THINKPAD_ACPI_VIDEO
389 bool "Video output control support"
390 depends on THINKPAD_ACPI
393 Allows the thinkpad_acpi driver to provide an interface to control
394 the various video output ports.
396 This feature often won't work well, depending on ThinkPad model,
397 display state, video output devices in use, whether there is a X
398 server running, phase of the moon, and the current mood of
399 Schroedinger's cat. If you can use X.org's RandR to control
400 your ThinkPad's video output ports instead of this feature,
401 don't think twice: do it and say N here to save memory and avoid
402 bad interactions with X.org.
404 NOTE: access to this feature is limited to processes with the
405 CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
406 where it interacts badly with X.org.
408 If you are not sure, say Y here but do try to check if you could
409 be using X.org RandR instead.
411 config THINKPAD_ACPI_HOTKEY_POLL
412 bool "Support NVRAM polling for hot keys"
413 depends on THINKPAD_ACPI
416 Some thinkpad models benefit from NVRAM polling to detect a few of
417 the hot key press events. If you know your ThinkPad model does not
418 need to do NVRAM polling to support any of the hot keys you use,
419 unselecting this option will save about 1kB of memory.
421 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
422 unlikely to need NVRAM polling in their latest BIOS versions.
424 NVRAM polling can detect at most the following keys: ThinkPad/Access
425 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
426 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
428 If you are not sure, say Y here. The driver enables polling only if
429 it is strictly necessary to do so.
432 tristate "Thinkpad Hard Drive Active Protection System (hdaps)"
433 depends on INPUT && X86
437 This driver provides support for the IBM Hard Drive Active Protection
438 System (hdaps), which provides an accelerometer and other misc. data.
439 ThinkPads starting with the R50, T41, and X40 are supported. The
440 accelerometer data is readable via sysfs.
442 This driver also provides an absolute input class device, allowing
443 the laptop to act as a pinball machine-esque joystick.
445 If your ThinkPad is not recognized by the driver, please update to latest
446 BIOS. This is especially the case for some R52 ThinkPads.
448 Say Y here if you have an applicable laptop and want to experience
449 the awesome power of hdaps.
452 tristate "Thermal Management driver for Intel menlow platform"
453 depends on ACPI_THERMAL
456 ACPI thermal management enhancement driver on
457 Intel Menlow platform.

514 tristate "Eee PC WMI Driver"
517 This is a driver for newer Eee PC laptops. It adds extra features
518 like wireless radio and bluetooth control, leds, hotkeys, backlight...
520 For more informations, see
521 <file:Documentation/ABI/testing/sysfs-platform-asus-wmi>
523 If you have an ACPI-WMI compatible Eee PC laptop (>= 1000), say Y or M
530 This driver adds support for the ACPI-WMI (Windows Management
531 Instrumentation) mapper device (PNP0C14) found on some systems.
533 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
534 ACPI firmware to userspace - this is done through various vendor
535 defined methods and data blocks in a PNP0C14 device, which are then
536 made available for userspace to call.
538 The implementation of this in Linux currently only exposes this to
539 other kernel space drivers.
541 This driver is a required dependency to build the firmware specific
542 drivers needed on many machines, including Acer and HP laptops.
544 It is safe to enable this driver even if your DSDT doesn't define
545 any ACPI-WMI devices.
548 tristate "MSI WMI extras"
551 depends on BACKLIGHT_CLASS_DEVICE
552 select INPUT_SPARSEKMAP
554 Say Y here if you want to support WMI-based hotkeys on MSI laptops.

567 If you have a Topstar laptop, say Y or M here.
570 tristate "Toshiba Laptop Extras"
575 depends on BACKLIGHT_CLASS_DEVICE
577 depends on RFKILL || RFKILL = n
579 select INPUT_SPARSEKMAP
581 This driver adds support for access to certain system settings
582 on "legacy free" Toshiba laptops. These laptops can be recognized by
583 their lack of a BIOS setup menu and APM support.
585 On these machines, all system configuration is handled through the
586 ACPI. This driver is required for access to controls not covered
587 by the general ACPI drivers, such as LCD brightness, video output,
590 This driver differs from the non-ACPI Toshiba laptop driver (located
591 under "Processor type and features") in several aspects.
592 Configuration is accessed by reading and writing text files in the
593 /proc tree instead of by program interface to /dev. Furthermore, no
594 power management functions are exposed, as those are handled by the
595 general ACPI drivers.
597 More information about this driver is available at
598 <http://memebeam.org/toys/ToshibaAcpiDriver>.
600 If you have a legacy free Toshiba laptop (such as the Libretto L1

684 Enable support for IBM Premium Real Time Mode (PRTM).
685 This module will allow you the enter and exit PRTM in the BIOS via
686 sysfs on platforms that support this feature. System in PRTM will
687 not receive CPU-generated SMIs for recoverable errors. Use of this
688 feature without proper support may void your hardware warranty.
690 If the proper BIOS support is found the driver will load and create
691 /sys/devices/system/ibm_rtl/. The "state" variable will indicate
692 whether or not the BIOS is in PRTM.
693 state = 0 (BIOS SMIs on)
694 state = 1 (BIOS SMIs off)
