102 tristate "Fujitsu Laptop Extras"
105 depends on BACKLIGHT_CLASS_DEVICE
106 depends on LEDS_CLASS || LEDS_CLASS=n
108 This is a driver for laptops built by Fujitsu:
110 * P2xxx/P5xxx/S6xxx/S7xxx series Lifebooks
111 * Possibly other Fujitsu laptop models
112 * Tested with S6410 and S7020
114 It adds support for LCD brightness control and some hotkeys.
116 If you have a Fujitsu laptop, say Y or M here.
118 config FUJITSU_LAPTOP_DEBUG
119 bool "Verbose debug mode for Fujitsu Laptop Extras"
120 depends on FUJITSU_LAPTOP
123 Enables extra debug output from the fujitsu extras driver, at the
124 expense of a slight increase in driver size.
126 If you are not sure, say N here.
129 tristate "HP Compaq TC1100 Tablet WMI Extras (EXPERIMENTAL)"
131 depends on EXPERIMENTAL
135 This is a driver for the WMI extensions (wireless and bluetooth power
136 control) of the HP Compaq TC1100 tablet.
139 tristate "HP WMI extras"
142 depends on RFKILL || RFKILL = n
144 Say Y here if you want to support WMI-based hotkeys on HP laptops and
145 to read data from WMI such as docking or ambient light sensor state.

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

168 If you have an MSI S270 laptop, say Y or M here.
170 config PANASONIC_LAPTOP
171 tristate "Panasonic Laptop Extras"
172 depends on INPUT && ACPI
173 depends on BACKLIGHT_CLASS_DEVICE
175 This driver adds support for access to backlight control and hotkeys
176 on Panasonic Let's Note laptops.
178 If you have a Panasonic Let's note laptop (such as the R1(N variant),
179 R2, R3, R5, T2, W2 and Y2 series), say Y.
182 tristate "Compal Laptop Extras"
184 depends on BACKLIGHT_CLASS_DEVICE
187 depends on POWER_SUPPLY
189 This is a driver for laptops built by Compal:
196 It adds support for Bluetooth, WLAN and LCD brightness control.
198 If you have an Compal FL9x/IFL9x/FT00 laptop, say Y or M here.
201 tristate "Sony Laptop Extras"
203 select BACKLIGHT_CLASS_DEVICE
207 This mini-driver drives the SNC and SPIC devices present in the ACPI
208 BIOS of the Sony Vaio laptops.
210 It gives access to some extra laptop functionalities like Bluetooth,
211 screen brightness control, Fn keys and allows powering on/off some
214 Read <file:Documentation/laptops/sony-laptop.txt> for more information.
217 bool "Sonypi compatibility"
218 depends on SONY_LAPTOP
220 Build the sonypi driver compatibility code into the sony-laptop driver.
223 tristate "ThinkPad ACPI Laptop Extras"
226 depends on RFKILL || RFKILL = n
227 select BACKLIGHT_LCD_SUPPORT
228 select BACKLIGHT_CLASS_DEVICE
234 This is a driver for the IBM and Lenovo ThinkPad laptops. It adds
235 support for Fn-Fx key combinations, Bluetooth control, video
236 output switching, ThinkLight control, UltraBay eject and more.
237 For more information about this driver see
238 <file:Documentation/laptops/thinkpad-acpi.txt> and
239 <http://ibm-acpi.sf.net/> .
241 This driver was formerly known as ibm-acpi.
243 Extra functionality will be available if the rfkill (CONFIG_RFKILL)
244 and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
245 Note that if you want ThinkPad-ACPI to be built-in instead of
246 modular, ALSA and rfkill will also have to be built-in.
248 If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.
250 config THINKPAD_ACPI_ALSA_SUPPORT
251 bool "Console audio control ALSA interface"
252 depends on THINKPAD_ACPI
254 depends on SND = y || THINKPAD_ACPI = SND
257 Enables monitoring of the built-in console audio output control
258 (headphone and speakers), which is operated by the mute and (in
259 some ThinkPad models) volume hotkeys.
261 If this option is enabled, ThinkPad-ACPI will export an ALSA card
262 with a single read-only mixer control, which should be used for
263 on-screen-display feedback purposes by the Desktop Environment.
265 Optionally, the driver will also allow software control (the
266 ALSA mixer will be made read-write). Please refer to the driver
267 documentation for details.
269 All IBM models have both volume and mute control. Newer Lenovo
270 models only have mute control (the volume hotkeys are just normal
271 keys and volume control is done through the main HDA mixer).
273 config THINKPAD_ACPI_DEBUGFACILITIES
274 bool "Maintainer debug facilities"
275 depends on THINKPAD_ACPI
278 Enables extra stuff in the thinkpad-acpi which is completely useless
279 for normal use. Read the driver source to find out what it does.
281 Say N here, unless you were told by a kernel maintainer to do
284 config THINKPAD_ACPI_DEBUG
285 bool "Verbose debug mode"
286 depends on THINKPAD_ACPI
289 Enables extra debugging information, at the expense of a slightly
290 increase in driver size.
292 If you are not sure, say N here.
294 config THINKPAD_ACPI_UNSAFE_LEDS
295 bool "Allow control of important LEDs (unsafe)"
296 depends on THINKPAD_ACPI
299 Overriding LED state on ThinkPads can mask important
300 firmware alerts (like critical battery condition), or misled
301 the user into damaging the hardware (undocking or ejecting
302 the bay while buses are still active), etc.
304 LED control on the ThinkPad is write-only (with very few
305 exceptions on very ancient models), which makes it
306 impossible to know beforehand if important information will
307 be lost when one changes LED state.
309 Users that know what they are doing can enable this option
310 and the driver will allow control of every LED, including
311 the ones on the dock stations.
313 Never enable this option on a distribution kernel.
315 Say N here, unless you are building a kernel for your own
316 use, and need to control the important firmware LEDs.
318 config THINKPAD_ACPI_VIDEO
319 bool "Video output control support"
320 depends on THINKPAD_ACPI
323 Allows the thinkpad_acpi driver to provide an interface to control
324 the various video output ports.
326 This feature often won't work well, depending on ThinkPad model,
327 display state, video output devices in use, whether there is a X
328 server running, phase of the moon, and the current mood of
329 Schroedinger's cat. If you can use X.org's RandR to control
330 your ThinkPad's video output ports instead of this feature,
331 don't think twice: do it and say N here to save memory and avoid
332 bad interactions with X.org.
334 NOTE: access to this feature is limited to processes with the
335 CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
336 where it interacts badly with X.org.
338 If you are not sure, say Y here but do try to check if you could
339 be using X.org RandR instead.
341 config THINKPAD_ACPI_HOTKEY_POLL
342 bool "Support NVRAM polling for hot keys"
343 depends on THINKPAD_ACPI
346 Some thinkpad models benefit from NVRAM polling to detect a few of
347 the hot key press events. If you know your ThinkPad model does not
348 need to do NVRAM polling to support any of the hot keys you use,
349 unselecting this option will save about 1kB of memory.
351 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
352 unlikely to need NVRAM polling in their latest BIOS versions.
354 NVRAM polling can detect at most the following keys: ThinkPad/Access
355 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
356 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
358 If you are not sure, say Y here. The driver enables polling only if
359 it is strictly necessary to do so.
362 tristate "Thermal Management driver for Intel menlow platform"
363 depends on ACPI_THERMAL
366 ACPI thermal management enhancement driver on
367 Intel Menlow platform.
372 tristate "Eee PC Hotkey Driver (EXPERIMENTAL)"
375 depends on EXPERIMENTAL
376 depends on RFKILL || RFKILL = n
377 depends on HOTPLUG_PCI
378 select BACKLIGHT_CLASS_DEVICE
382 select INPUT_SPARSEKMAP
384 This driver supports the Fn-Fx keys on Eee PC laptops.
386 It also gives access to some extra laptop functionalities like
387 Bluetooth, backlight and allows powering on/off some other
390 If you have an Eee PC laptop, say Y or M here.
393 tristate "Eee PC WMI Hotkey Driver (EXPERIMENTAL)"
396 depends on EXPERIMENTAL
397 depends on BACKLIGHT_CLASS_DEVICE
398 select INPUT_SPARSEKMAP
400 Say Y here if you want to support WMI-based hotkeys on Eee PC laptops.
402 To compile this driver as a module, choose M here: the module will
409 This driver adds support for the ACPI-WMI (Windows Management
410 Instrumentation) mapper device (PNP0C14) found on some systems.
412 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
413 ACPI firmware to userspace - this is done through various vendor
414 defined methods and data blocks in a PNP0C14 device, which are then
415 made available for userspace to call.
417 The implementation of this in Linux currently only exposes this to
418 other kernel space drivers.
420 This driver is a required dependency to build the firmware specific
421 drivers needed on many machines, including Acer and HP laptops.
423 It is safe to enable this driver even if your DSDT doesn't define
424 any ACPI-WMI devices.
427 tristate "MSI WMI extras"
430 depends on BACKLIGHT_CLASS_DEVICE
431 select INPUT_SPARSEKMAP
433 Say Y here if you want to support WMI-based hotkeys on MSI laptops.
435 To compile this driver as a module, choose M here: the module will
439 tristate "ASUS/Medion Laptop Extras (DEPRECATED)"
441 select BACKLIGHT_CLASS_DEVICE
443 This driver provides support for extra features of ACPI-compatible
444 ASUS laptops. As some of Medion laptops are made by ASUS, it may also
445 support some Medion laptops (such as 9675 for example). It makes all
446 the extra buttons generate standard ACPI events that go through
447 /proc/acpi/events, and (on some models) adds support for changing the
448 display brightness and output, switching the LCD backlight on and off,
449 and most importantly, allows you to blink those fancy LEDs intended
450 for reporting mail and wireless status.
452 Note: display switching code is currently considered EXPERIMENTAL,
453 toying with these values may even lock your machine.
455 All settings are changed via /proc/acpi/asus directory entries. Owner
456 and group for these entries can be set with asus_uid and asus_gid
459 More information and a userspace daemon for handling the extra buttons
460 at <http://acpi4asus.sf.net>.
462 If you have an ACPI-compatible ASUS laptop, say Y or M here. This
463 driver is still under development, so if your laptop is unsupported or
464 something works not quite as expected, please use the mailing list
465 available on the above page (acpi4asus-user@lists.sourceforge.net).
467 NOTE: This driver is deprecated and will probably be removed soon,
468 use asus-laptop instead.
470 config TOPSTAR_LAPTOP
471 tristate "Topstar Laptop Extras"
475 This driver adds support for hotkeys found on Topstar laptops.
477 If you have a Topstar laptop, say Y or M here.
480 tristate "Toshiba Laptop Extras"
483 depends on RFKILL || RFKILL = n
485 select BACKLIGHT_CLASS_DEVICE
487 This driver adds support for access to certain system settings
488 on "legacy free" Toshiba laptops. These laptops can be recognized by
489 their lack of a BIOS setup menu and APM support.
491 On these machines, all system configuration is handled through the
492 ACPI. This driver is required for access to controls not covered
493 by the general ACPI drivers, such as LCD brightness, video output,
496 This driver differs from the non-ACPI Toshiba laptop driver (located
497 under "Processor type and features") in several aspects.
498 Configuration is accessed by reading and writing text files in the
499 /proc tree instead of by program interface to /dev. Furthermore, no
500 power management functions are exposed, as those are handled by the
501 general ACPI drivers.
503 More information about this driver is available at
504 <http://memebeam.org/toys/ToshibaAcpiDriver>.
506 If you have a legacy free Toshiba laptop (such as the Libretto L1
509 config TOSHIBA_BT_RFKILL
510 tristate "Toshiba Bluetooth RFKill switch support"
513 This driver adds support for Bluetooth events for the RFKill
514 switch on modern Toshiba laptops with full ACPI support and
517 This driver handles RFKill events for the TOS6205 Bluetooth,
518 and re-enables it when the switch is set back to the 'on'
521 If you have a modern Toshiba laptop with a Bluetooth and an
522 RFKill switch (such as the Portege R500), say Y.
525 tristate "CMPC Laptop Extras"
526 depends on X86 && ACPI
527 depends on RFKILL || RFKILL=n
529 select BACKLIGHT_CLASS_DEVICE
532 Support for Intel Classmate PC ACPI devices, including some
533 keys as input device, backlight device, tablet and accelerometer
537 bool "Intel SCU IPC Support"
541 IPC is used to bridge the communications between kernel and SCU on
542 some embedded Intel x86 platforms. This is not needed for PC-type
545 config GPIO_INTEL_PMIC
546 bool "Intel PMIC GPIO support"
547 depends on INTEL_SCU_IPC && GPIOLIB
549 Say Y here to support GPIO via the SCU IPC interface
550 on Intel MID platforms.
553 bool "Restricted Access Region Register Driver"
554 depends on PCI && X86_MRST
557 This driver allows other kernel drivers access to the
558 contents of the restricted access region control registers.
560 The restricted access region control registers
561 (rar_registers) are used to pass address and
562 locking information on restricted access regions
563 to other drivers that use restricted access regions.
565 The restricted access regions are regions of memory
566 on the Intel MID Platform that are not accessible to
567 the x86 processor, but are accessible to dedicated
568 processors on board peripheral devices.
570 The purpose of the restricted access regions is to
571 protect sensitive data from compromise by unauthorized
572 programs running on the x86 processor.
575 tristate "Intel Intelligent Power Sharing"
578 Intel Calpella platforms support dynamic power sharing between the
579 CPU and GPU, maximizing performance in a given TDP. This driver,
580 along with the CPU frequency and i915 drivers, provides that
581 functionality. If in doubt, say Y here; it will only load on
