243 This mini-driver drives the SNC and SPIC devices present in the ACPI
244 BIOS of the Sony Vaio laptops.
246 It gives access to some extra laptop functionalities like Bluetooth,
247 screen brightness control, Fn keys and allows powering on/off some

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

494 like wireless radio and bluetooth control, leds, hotkeys, backlight...
496 For more informations, see
497 <file:Documentation/ABI/testing/sysfs-platform-asus-wmi>
499 If you have an ACPI-WMI compatible Eee PC laptop (>= 1000), say Y or M
506 This driver adds support for the ACPI-WMI (Windows Management
507 Instrumentation) mapper device (PNP0C14) found on some systems.
509 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
510 ACPI firmware to userspace - this is done through various vendor
511 defined methods and data blocks in a PNP0C14 device, which are then
512 made available for userspace to call.
514 The implementation of this in Linux currently only exposes this to
515 other kernel space drivers.
517 This driver is a required dependency to build the firmware specific
518 drivers needed on many machines, including Acer and HP laptops.
520 It is safe to enable this driver even if your DSDT doesn't define
521 any ACPI-WMI devices.
524 tristate "MSI WMI extras"
527 depends on BACKLIGHT_CLASS_DEVICE
528 select INPUT_SPARSEKMAP
530 Say Y here if you want to support WMI-based hotkeys on MSI laptops.
532 To compile this driver as a module, choose M here: the module will
536 tristate "ASUS/Medion Laptop Extras (DEPRECATED)"
538 select BACKLIGHT_CLASS_DEVICE
540 This driver provides support for extra features of ACPI-compatible
541 ASUS laptops. As some of Medion laptops are made by ASUS, it may also
542 support some Medion laptops (such as 9675 for example). It makes all
543 the extra buttons generate standard ACPI events that go through
544 /proc/acpi/events, and (on some models) adds support for changing the
545 display brightness and output, switching the LCD backlight on and off,
546 and most importantly, allows you to blink those fancy LEDs intended
547 for reporting mail and wireless status.
549 Note: display switching code is currently considered EXPERIMENTAL,
550 toying with these values may even lock your machine.
552 All settings are changed via /proc/acpi/asus directory entries. Owner
553 and group for these entries can be set with asus_uid and asus_gid
556 More information and a userspace daemon for handling the extra buttons
557 at <http://acpi4asus.sf.net>.
559 If you have an ACPI-compatible ASUS laptop, say Y or M here. This
560 driver is still under development, so if your laptop is unsupported or
561 something works not quite as expected, please use the mailing list
562 available on the above page (acpi4asus-user@lists.sourceforge.net).
564 NOTE: This driver is deprecated and will probably be removed soon,
565 use asus-laptop instead.
567 config TOPSTAR_LAPTOP
568 tristate "Topstar Laptop Extras"
571 select INPUT_SPARSEKMAP
573 This driver adds support for hotkeys found on Topstar laptops.
575 If you have a Topstar laptop, say Y or M here.
578 tristate "Toshiba Laptop Extras"
582 depends on BACKLIGHT_CLASS_DEVICE
584 depends on RFKILL || RFKILL = n
586 select INPUT_SPARSEKMAP
588 This driver adds support for access to certain system settings
589 on "legacy free" Toshiba laptops. These laptops can be recognized by
590 their lack of a BIOS setup menu and APM support.
592 On these machines, all system configuration is handled through the
593 ACPI. This driver is required for access to controls not covered
594 by the general ACPI drivers, such as LCD brightness, video output,
597 This driver differs from the non-ACPI Toshiba laptop driver (located
598 under "Processor type and features") in several aspects.
599 Configuration is accessed by reading and writing text files in the
600 /proc tree instead of by program interface to /dev. Furthermore, no
601 power management functions are exposed, as those are handled by the
602 general ACPI drivers.
604 More information about this driver is available at
605 <http://memebeam.org/toys/ToshibaAcpiDriver>.

614 This driver adds support for Bluetooth events for the RFKill
615 switch on modern Toshiba laptops with full ACPI support and
618 This driver handles RFKill events for the TOS6205 Bluetooth,
619 and re-enables it when the switch is set back to the 'on'
622 If you have a modern Toshiba laptop with a Bluetooth and an
623 RFKill switch (such as the Portege R500), say Y.

674 Say Y here to enable thermal driver support for the Intel Medfield
678 bool "Restricted Access Region Register Driver"
679 depends on PCI && X86_MRST
682 This driver allows other kernel drivers access to the
683 contents of the restricted access region control registers.
685 The restricted access region control registers
686 (rar_registers) are used to pass address and
687 locking information on restricted access regions
688 to other drivers that use restricted access regions.
690 The restricted access regions are regions of memory
691 on the Intel MID Platform that are not accessible to
692 the x86 processor, but are accessible to dedicated
693 processors on board peripheral devices.
695 The purpose of the restricted access regions is to
696 protect sensitive data from compromise by unauthorized
697 programs running on the x86 processor.
700 tristate "Intel Intelligent Power Sharing"
703 Intel Calpella platforms support dynamic power sharing between the
704 CPU and GPU, maximizing performance in a given TDP. This driver,
705 along with the CPU frequency and i915 drivers, provides that
706 functionality. If in doubt, say Y here; it will only load on

713 Enable support for IBM Premium Real Time Mode (PRTM).
714 This module will allow you the enter and exit PRTM in the BIOS via
715 sysfs on platforms that support this feature. System in PRTM will
716 not receive CPU-generated SMIs for recoverable errors. Use of this
717 feature without proper support may void your hardware warranty.
719 If the proper BIOS support is found the driver will load and create
720 /sys/devices/system/ibm_rtl/. The "state" variable will indicate
721 whether or not the BIOS is in PRTM.
