115 It adds support for LCD brightness control and some hotkeys.
117 If you have a Fujitsu laptop, say Y or M here.
119 config FUJITSU_LAPTOP_DEBUG
120 bool "Verbose debug mode for Fujitsu Laptop Extras"
121 depends on FUJITSU_LAPTOP
124 Enables extra debug output from the fujitsu extras driver, at the
125 expense of a slight increase in driver size.
127 If you are not sure, say N here.
130 tristate "HP Compaq TC1100 Tablet WMI Extras (EXPERIMENTAL)"
132 depends on EXPERIMENTAL
136 This is a driver for the WMI extensions (wireless and bluetooth power
137 control) of the HP Compaq TC1100 tablet.

153 tristate "MSI Laptop Extras"
155 depends on BACKLIGHT_CLASS_DEVICE
157 depends on SERIO_I8042
159 This is a driver for laptops built by MSI (MICRO-STAR
162 MSI MegaBook S270 (MS-1013)
163 Cytron/TCM/Medion/Tchibo MD96100/SAM2000
165 It adds support for Bluetooth, WLAN and LCD brightness control.

173 tristate "Panasonic Laptop Extras"
174 depends on INPUT && ACPI
175 depends on BACKLIGHT_CLASS_DEVICE
176 select INPUT_SPARSEKMAP
178 This driver adds support for access to backlight control and hotkeys
179 on Panasonic Let's Note laptops.
181 If you have a Panasonic Let's note laptop (such as the R1(N variant),
182 R2, R3, R5, T2, W2 and Y2 series), say Y.
185 tristate "Compal Laptop Extras"
187 depends on BACKLIGHT_CLASS_DEVICE
190 depends on POWER_SUPPLY
192 This is a driver for laptops built by Compal:
199 It adds support for Bluetooth, WLAN and LCD brightness control.
201 If you have an Compal FL9x/IFL9x/FT00 laptop, say Y or M here.
204 tristate "Sony Laptop Extras"
206 select BACKLIGHT_CLASS_DEVICE
210 This mini-driver drives the SNC and SPIC devices present in the ACPI
211 BIOS of the Sony Vaio laptops.
213 It gives access to some extra laptop functionalities like Bluetooth,
214 screen brightness control, Fn keys and allows powering on/off some

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

423 tristate "Eee PC WMI Hotkey Driver (EXPERIMENTAL)"
426 depends on EXPERIMENTAL
427 depends on BACKLIGHT_CLASS_DEVICE
428 select INPUT_SPARSEKMAP
430 Say Y here if you want to support WMI-based hotkeys on Eee PC laptops.
432 To compile this driver as a module, choose M here: the module will
439 This driver adds support for the ACPI-WMI (Windows Management
440 Instrumentation) mapper device (PNP0C14) found on some systems.
442 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
443 ACPI firmware to userspace - this is done through various vendor
444 defined methods and data blocks in a PNP0C14 device, which are then
445 made available for userspace to call.
447 The implementation of this in Linux currently only exposes this to
448 other kernel space drivers.
450 This driver is a required dependency to build the firmware specific
451 drivers needed on many machines, including Acer and HP laptops.
453 It is safe to enable this driver even if your DSDT doesn't define
454 any ACPI-WMI devices.
457 tristate "MSI WMI extras"
460 depends on BACKLIGHT_CLASS_DEVICE
461 select INPUT_SPARSEKMAP
463 Say Y here if you want to support WMI-based hotkeys on MSI laptops.
465 To compile this driver as a module, choose M here: the module will
469 tristate "ASUS/Medion Laptop Extras (DEPRECATED)"
471 select BACKLIGHT_CLASS_DEVICE
473 This driver provides support for extra features of ACPI-compatible
474 ASUS laptops. As some of Medion laptops are made by ASUS, it may also
475 support some Medion laptops (such as 9675 for example). It makes all
476 the extra buttons generate standard ACPI events that go through
477 /proc/acpi/events, and (on some models) adds support for changing the
478 display brightness and output, switching the LCD backlight on and off,
479 and most importantly, allows you to blink those fancy LEDs intended
480 for reporting mail and wireless status.
482 Note: display switching code is currently considered EXPERIMENTAL,
483 toying with these values may even lock your machine.
485 All settings are changed via /proc/acpi/asus directory entries. Owner
486 and group for these entries can be set with asus_uid and asus_gid
489 More information and a userspace daemon for handling the extra buttons
490 at <http://acpi4asus.sf.net>.
492 If you have an ACPI-compatible ASUS laptop, say Y or M here. This
493 driver is still under development, so if your laptop is unsupported or
494 something works not quite as expected, please use the mailing list
495 available on the above page (acpi4asus-user@lists.sourceforge.net).
497 NOTE: This driver is deprecated and will probably be removed soon,
498 use asus-laptop instead.
500 config TOPSTAR_LAPTOP
501 tristate "Topstar Laptop Extras"
504 select INPUT_SPARSEKMAP
506 This driver adds support for hotkeys found on Topstar laptops.
508 If you have a Topstar laptop, say Y or M here.
511 tristate "Toshiba Laptop Extras"
513 depends on LEDS_CLASS
515 depends on BACKLIGHT_CLASS_DEVICE
517 depends on RFKILL || RFKILL = n
519 select INPUT_SPARSEKMAP
521 This driver adds support for access to certain system settings
522 on "legacy free" Toshiba laptops. These laptops can be recognized by
523 their lack of a BIOS setup menu and APM support.
525 On these machines, all system configuration is handled through the
526 ACPI. This driver is required for access to controls not covered
527 by the general ACPI drivers, such as LCD brightness, video output,
530 This driver differs from the non-ACPI Toshiba laptop driver (located
531 under "Processor type and features") in several aspects.
532 Configuration is accessed by reading and writing text files in the
533 /proc tree instead of by program interface to /dev. Furthermore, no
534 power management functions are exposed, as those are handled by the
535 general ACPI drivers.
537 More information about this driver is available at
538 <http://memebeam.org/toys/ToshibaAcpiDriver>.
540 If you have a legacy free Toshiba laptop (such as the Libretto L1
543 config TOSHIBA_BT_RFKILL
544 tristate "Toshiba Bluetooth RFKill switch support"
547 This driver adds support for Bluetooth events for the RFKill
548 switch on modern Toshiba laptops with full ACPI support and
551 This driver handles RFKill events for the TOS6205 Bluetooth,
552 and re-enables it when the switch is set back to the 'on'
555 If you have a modern Toshiba laptop with a Bluetooth and an
556 RFKill switch (such as the Portege R500), say Y.
559 tristate "CMPC Laptop Extras"
560 depends on X86 && ACPI
561 depends on RFKILL || RFKILL=n
563 select BACKLIGHT_CLASS_DEVICE
566 Support for Intel Classmate PC ACPI devices, including some
567 keys as input device, backlight device, tablet and accelerometer
571 bool "Intel SCU IPC Support"
575 IPC is used to bridge the communications between kernel and SCU on
576 some embedded Intel x86 platforms. This is not needed for PC-type
579 config GPIO_INTEL_PMIC
580 bool "Intel PMIC GPIO support"
581 depends on INTEL_SCU_IPC && GPIOLIB
583 Say Y here to support GPIO via the SCU IPC interface
584 on Intel MID platforms.
587 bool "Restricted Access Region Register Driver"
588 depends on PCI && X86_MRST
591 This driver allows other kernel drivers access to the
592 contents of the restricted access region control registers.
594 The restricted access region control registers
595 (rar_registers) are used to pass address and
596 locking information on restricted access regions
597 to other drivers that use restricted access regions.
599 The restricted access regions are regions of memory
600 on the Intel MID Platform that are not accessible to
601 the x86 processor, but are accessible to dedicated
602 processors on board peripheral devices.
604 The purpose of the restricted access regions is to
605 protect sensitive data from compromise by unauthorized
606 programs running on the x86 processor.
609 tristate "Intel Intelligent Power Sharing"
612 Intel Calpella platforms support dynamic power sharing between the
613 CPU and GPU, maximizing performance in a given TDP. This driver,
614 along with the CPU frequency and i915 drivers, provides that
615 functionality. If in doubt, say Y here; it will only load on
619 tristate "Device driver to enable PRTL support"
620 depends on X86 && PCI
622 Enable support for IBM Premium Real Time Mode (PRTM).
623 This module will allow you the enter and exit PRTM in the BIOS via
624 sysfs on platforms that support this feature. System in PRTM will
625 not receive CPU-generated SMIs for recoverable errors. Use of this
626 feature without proper support may void your hardware warranty.
628 If the proper BIOS support is found the driver will load and create
629 /sys/devices/system/ibm_rtl/. The "state" variable will indicate
630 whether or not the BIOS is in PRTM.
631 state = 0 (BIOS SMIs on)
632 state = 1 (BIOS SMIs off)
635 tristate "OLPC XO-1 software RF kill switch"
