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.

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"
229 select INPUT_SPARSEKMAP
231 This is a driver for the rfkill switches on Lenovo IdeaPad netbooks.
234 tristate "ThinkPad ACPI Laptop Extras"
237 depends on RFKILL || RFKILL = n
238 select BACKLIGHT_LCD_SUPPORT
239 select BACKLIGHT_CLASS_DEVICE
245 This is a driver for the IBM and Lenovo ThinkPad laptops. It adds
246 support for Fn-Fx key combinations, Bluetooth control, video
247 output switching, ThinkLight control, UltraBay eject and more.
248 For more information about this driver see
249 <file:Documentation/laptops/thinkpad-acpi.txt> and
250 <http://ibm-acpi.sf.net/> .
252 This driver was formerly known as ibm-acpi.
254 Extra functionality will be available if the rfkill (CONFIG_RFKILL)
255 and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
256 Note that if you want ThinkPad-ACPI to be built-in instead of
257 modular, ALSA and rfkill will also have to be built-in.
259 If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.
261 config THINKPAD_ACPI_ALSA_SUPPORT
262 bool "Console audio control ALSA interface"
263 depends on THINKPAD_ACPI
265 depends on SND = y || THINKPAD_ACPI = SND
268 Enables monitoring of the built-in console audio output control
269 (headphone and speakers), which is operated by the mute and (in
270 some ThinkPad models) volume hotkeys.
272 If this option is enabled, ThinkPad-ACPI will export an ALSA card
273 with a single read-only mixer control, which should be used for
274 on-screen-display feedback purposes by the Desktop Environment.
276 Optionally, the driver will also allow software control (the
277 ALSA mixer will be made read-write). Please refer to the driver
278 documentation for details.
280 All IBM models have both volume and mute control. Newer Lenovo
281 models only have mute control (the volume hotkeys are just normal
282 keys and volume control is done through the main HDA mixer).
284 config THINKPAD_ACPI_DEBUGFACILITIES
285 bool "Maintainer debug facilities"
286 depends on THINKPAD_ACPI
289 Enables extra stuff in the thinkpad-acpi which is completely useless
290 for normal use. Read the driver source to find out what it does.
292 Say N here, unless you were told by a kernel maintainer to do
295 config THINKPAD_ACPI_DEBUG
296 bool "Verbose debug mode"
297 depends on THINKPAD_ACPI
300 Enables extra debugging information, at the expense of a slightly
301 increase in driver size.
303 If you are not sure, say N here.
305 config THINKPAD_ACPI_UNSAFE_LEDS
306 bool "Allow control of important LEDs (unsafe)"
307 depends on THINKPAD_ACPI
310 Overriding LED state on ThinkPads can mask important
311 firmware alerts (like critical battery condition), or misled
312 the user into damaging the hardware (undocking or ejecting
313 the bay while buses are still active), etc.
315 LED control on the ThinkPad is write-only (with very few
316 exceptions on very ancient models), which makes it
317 impossible to know beforehand if important information will
318 be lost when one changes LED state.
320 Users that know what they are doing can enable this option
321 and the driver will allow control of every LED, including
322 the ones on the dock stations.
324 Never enable this option on a distribution kernel.
326 Say N here, unless you are building a kernel for your own
327 use, and need to control the important firmware LEDs.
329 config THINKPAD_ACPI_VIDEO
330 bool "Video output control support"
331 depends on THINKPAD_ACPI
334 Allows the thinkpad_acpi driver to provide an interface to control
335 the various video output ports.
337 This feature often won't work well, depending on ThinkPad model,
338 display state, video output devices in use, whether there is a X
339 server running, phase of the moon, and the current mood of
340 Schroedinger's cat. If you can use X.org's RandR to control
341 your ThinkPad's video output ports instead of this feature,
342 don't think twice: do it and say N here to save memory and avoid
343 bad interactions with X.org.
345 NOTE: access to this feature is limited to processes with the
346 CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
347 where it interacts badly with X.org.
349 If you are not sure, say Y here but do try to check if you could
350 be using X.org RandR instead.
352 config THINKPAD_ACPI_HOTKEY_POLL
353 bool "Support NVRAM polling for hot keys"
354 depends on THINKPAD_ACPI
357 Some thinkpad models benefit from NVRAM polling to detect a few of
358 the hot key press events. If you know your ThinkPad model does not
359 need to do NVRAM polling to support any of the hot keys you use,
360 unselecting this option will save about 1kB of memory.
362 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
363 unlikely to need NVRAM polling in their latest BIOS versions.
365 NVRAM polling can detect at most the following keys: ThinkPad/Access
366 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
367 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
369 If you are not sure, say Y here. The driver enables polling only if
370 it is strictly necessary to do so.
373 tristate "Thinkpad Hard Drive Active Protection System (hdaps)"
374 depends on INPUT && X86
378 This driver provides support for the IBM Hard Drive Active Protection
379 System (hdaps), which provides an accelerometer and other misc. data.
380 ThinkPads starting with the R50, T41, and X40 are supported. The
381 accelerometer data is readable via sysfs.
383 This driver also provides an absolute input class device, allowing
384 the laptop to act as a pinball machine-esque joystick.
386 If your ThinkPad is not recognized by the driver, please update to latest
387 BIOS. This is especially the case for some R52 ThinkPads.
389 Say Y here if you have an applicable laptop and want to experience
390 the awesome power of hdaps.
393 tristate "Thermal Management driver for Intel menlow platform"
394 depends on ACPI_THERMAL
397 ACPI thermal management enhancement driver on
398 Intel Menlow platform.
403 tristate "Eee PC Hotkey Driver (EXPERIMENTAL)"
406 depends on EXPERIMENTAL
407 depends on RFKILL || RFKILL = n
408 depends on HOTPLUG_PCI
409 select BACKLIGHT_CLASS_DEVICE
413 select INPUT_SPARSEKMAP
415 This driver supports the Fn-Fx keys on Eee PC laptops.
417 It also gives access to some extra laptop functionalities like
418 Bluetooth, backlight and allows powering on/off some other
421 If you have an Eee PC laptop, say Y or M here.
424 tristate "Eee PC WMI Hotkey Driver (EXPERIMENTAL)"
427 depends on EXPERIMENTAL
428 depends on BACKLIGHT_CLASS_DEVICE
429 depends on RFKILL || RFKILL = n
430 select INPUT_SPARSEKMAP
434 Say Y here if you want to support WMI-based hotkeys on Eee PC laptops.
436 To compile this driver as a module, choose M here: the module will
443 This driver adds support for the ACPI-WMI (Windows Management
444 Instrumentation) mapper device (PNP0C14) found on some systems.
446 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
447 ACPI firmware to userspace - this is done through various vendor
448 defined methods and data blocks in a PNP0C14 device, which are then
449 made available for userspace to call.
451 The implementation of this in Linux currently only exposes this to
452 other kernel space drivers.
454 This driver is a required dependency to build the firmware specific
455 drivers needed on many machines, including Acer and HP laptops.
457 It is safe to enable this driver even if your DSDT doesn't define
458 any ACPI-WMI devices.
461 tristate "MSI WMI extras"
464 depends on BACKLIGHT_CLASS_DEVICE
465 select INPUT_SPARSEKMAP
467 Say Y here if you want to support WMI-based hotkeys on MSI laptops.
469 To compile this driver as a module, choose M here: the module will
473 tristate "ASUS/Medion Laptop Extras (DEPRECATED)"
475 select BACKLIGHT_CLASS_DEVICE
477 This driver provides support for extra features of ACPI-compatible
478 ASUS laptops. As some of Medion laptops are made by ASUS, it may also
479 support some Medion laptops (such as 9675 for example). It makes all
480 the extra buttons generate standard ACPI events that go through
481 /proc/acpi/events, and (on some models) adds support for changing the
482 display brightness and output, switching the LCD backlight on and off,
483 and most importantly, allows you to blink those fancy LEDs intended
484 for reporting mail and wireless status.
486 Note: display switching code is currently considered EXPERIMENTAL,
487 toying with these values may even lock your machine.
489 All settings are changed via /proc/acpi/asus directory entries. Owner
490 and group for these entries can be set with asus_uid and asus_gid
493 More information and a userspace daemon for handling the extra buttons
494 at <http://acpi4asus.sf.net>.
496 If you have an ACPI-compatible ASUS laptop, say Y or M here. This
497 driver is still under development, so if your laptop is unsupported or
498 something works not quite as expected, please use the mailing list
499 available on the above page (acpi4asus-user@lists.sourceforge.net).
501 NOTE: This driver is deprecated and will probably be removed soon,
502 use asus-laptop instead.
504 config TOPSTAR_LAPTOP
505 tristate "Topstar Laptop Extras"
508 select INPUT_SPARSEKMAP
510 This driver adds support for hotkeys found on Topstar laptops.
512 If you have a Topstar laptop, say Y or M here.
515 tristate "Toshiba Laptop Extras"
517 depends on LEDS_CLASS
519 depends on BACKLIGHT_CLASS_DEVICE
521 depends on RFKILL || RFKILL = n
523 select INPUT_SPARSEKMAP
525 This driver adds support for access to certain system settings
526 on "legacy free" Toshiba laptops. These laptops can be recognized by
527 their lack of a BIOS setup menu and APM support.
529 On these machines, all system configuration is handled through the
530 ACPI. This driver is required for access to controls not covered
531 by the general ACPI drivers, such as LCD brightness, video output,
534 This driver differs from the non-ACPI Toshiba laptop driver (located
535 under "Processor type and features") in several aspects.
536 Configuration is accessed by reading and writing text files in the
537 /proc tree instead of by program interface to /dev. Furthermore, no
538 power management functions are exposed, as those are handled by the
539 general ACPI drivers.
541 More information about this driver is available at
542 <http://memebeam.org/toys/ToshibaAcpiDriver>.
544 If you have a legacy free Toshiba laptop (such as the Libretto L1
547 config TOSHIBA_BT_RFKILL
548 tristate "Toshiba Bluetooth RFKill switch support"
551 This driver adds support for Bluetooth events for the RFKill
552 switch on modern Toshiba laptops with full ACPI support and
555 This driver handles RFKill events for the TOS6205 Bluetooth,
556 and re-enables it when the switch is set back to the 'on'
559 If you have a modern Toshiba laptop with a Bluetooth and an
560 RFKill switch (such as the Portege R500), say Y.
563 tristate "CMPC Laptop Extras"
564 depends on X86 && ACPI
565 depends on RFKILL || RFKILL=n
567 select BACKLIGHT_CLASS_DEVICE
570 Support for Intel Classmate PC ACPI devices, including some
571 keys as input device, backlight device, tablet and accelerometer
575 bool "Intel SCU IPC Support"
579 IPC is used to bridge the communications between kernel and SCU on
580 some embedded Intel x86 platforms. This is not needed for PC-type
583 config INTEL_SCU_IPC_UTIL
584 tristate "Intel SCU IPC utility driver"
585 depends on INTEL_SCU_IPC
588 The IPC Util driver provides an interface with the SCU enabling
589 low level access for debug work and updating the firmware. Say
590 N unless you will be doing this on an Intel MID platform.
592 config GPIO_INTEL_PMIC
593 bool "Intel PMIC GPIO support"
594 depends on INTEL_SCU_IPC && GPIOLIB
596 Say Y here to support GPIO via the SCU IPC interface
597 on Intel MID platforms.
600 bool "Restricted Access Region Register Driver"
601 depends on PCI && X86_MRST
604 This driver allows other kernel drivers access to the
605 contents of the restricted access region control registers.
607 The restricted access region control registers
608 (rar_registers) are used to pass address and
609 locking information on restricted access regions
610 to other drivers that use restricted access regions.
612 The restricted access regions are regions of memory
613 on the Intel MID Platform that are not accessible to
614 the x86 processor, but are accessible to dedicated
615 processors on board peripheral devices.
617 The purpose of the restricted access regions is to
618 protect sensitive data from compromise by unauthorized
619 programs running on the x86 processor.
622 tristate "Intel Intelligent Power Sharing"
625 Intel Calpella platforms support dynamic power sharing between the
626 CPU and GPU, maximizing performance in a given TDP. This driver,
627 along with the CPU frequency and i915 drivers, provides that
628 functionality. If in doubt, say Y here; it will only load on
632 tristate "Device driver to enable PRTL support"
633 depends on X86 && PCI
635 Enable support for IBM Premium Real Time Mode (PRTM).
636 This module will allow you the enter and exit PRTM in the BIOS via
637 sysfs on platforms that support this feature. System in PRTM will
638 not receive CPU-generated SMIs for recoverable errors. Use of this
639 feature without proper support may void your hardware warranty.
641 If the proper BIOS support is found the driver will load and create
642 /sys/devices/system/ibm_rtl/. The "state" variable will indicate
643 whether or not the BIOS is in PRTM.
644 state = 0 (BIOS SMIs on)
645 state = 1 (BIOS SMIs off)
648 tristate "OLPC XO-1 software RF kill switch"
652 Support for enabling/disabling the WLAN interface on the OLPC XO-1
