109 This is a driver for laptops built by Fujitsu:
111 * P2xxx/P5xxx/S6xxx/S7xxx series Lifebooks
112 * Possibly other Fujitsu laptop models
113 * Tested with S6410 and S7020
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.
140 tristate "HP WMI extras"
143 depends on RFKILL || RFKILL = n

172 tristate "Panasonic Laptop Extras"
173 depends on INPUT && ACPI
174 depends on BACKLIGHT_CLASS_DEVICE
175 select INPUT_SPARSEKMAP
177 This driver adds support for access to backlight control and hotkeys
178 on Panasonic Let's Note laptops.
180 If you have a Panasonic Let's note laptop (such as the R1(N variant),
181 R2, R3, R5, T2, W2 and Y2 series), say Y.
184 tristate "Compal Laptop Extras"
186 depends on BACKLIGHT_CLASS_DEVICE
189 depends on POWER_SUPPLY
191 This is a driver for laptops built by Compal:
198 It adds support for Bluetooth, WLAN and LCD brightness control.
200 If you have an Compal FL9x/IFL9x/FT00 laptop, say Y or M here.
203 tristate "Sony Laptop Extras"
205 select BACKLIGHT_CLASS_DEVICE
209 This mini-driver drives the SNC and SPIC devices present in the ACPI
210 BIOS of the Sony Vaio laptops.
212 It gives access to some extra laptop functionalities like Bluetooth,
213 screen brightness control, Fn keys and allows powering on/off some
216 Read <file:Documentation/laptops/sony-laptop.txt> for more information.
219 bool "Sonypi compatibility"
220 depends on SONY_LAPTOP
222 Build the sonypi driver compatibility code into the sony-laptop driver.
225 tristate "Lenovo IdeaPad ACPI Laptop Extras"
229 This is a driver for the rfkill switches on Lenovo IdeaPad netbooks.
232 tristate "ThinkPad ACPI Laptop Extras"
235 depends on RFKILL || RFKILL = n
236 select BACKLIGHT_LCD_SUPPORT
237 select BACKLIGHT_CLASS_DEVICE
243 This is a driver for the IBM and Lenovo ThinkPad laptops. It adds
244 support for Fn-Fx key combinations, Bluetooth control, video
245 output switching, ThinkLight control, UltraBay eject and more.
246 For more information about this driver see
247 <file:Documentation/laptops/thinkpad-acpi.txt> and
248 <http://ibm-acpi.sf.net/> .
250 This driver was formerly known as ibm-acpi.
252 Extra functionality will be available if the rfkill (CONFIG_RFKILL)
253 and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
254 Note that if you want ThinkPad-ACPI to be built-in instead of
255 modular, ALSA and rfkill will also have to be built-in.
257 If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.
259 config THINKPAD_ACPI_ALSA_SUPPORT
260 bool "Console audio control ALSA interface"
261 depends on THINKPAD_ACPI
263 depends on SND = y || THINKPAD_ACPI = SND
266 Enables monitoring of the built-in console audio output control
267 (headphone and speakers), which is operated by the mute and (in
268 some ThinkPad models) volume hotkeys.
270 If this option is enabled, ThinkPad-ACPI will export an ALSA card
271 with a single read-only mixer control, which should be used for
272 on-screen-display feedback purposes by the Desktop Environment.
274 Optionally, the driver will also allow software control (the
275 ALSA mixer will be made read-write). Please refer to the driver
276 documentation for details.
278 All IBM models have both volume and mute control. Newer Lenovo
279 models only have mute control (the volume hotkeys are just normal
280 keys and volume control is done through the main HDA mixer).
282 config THINKPAD_ACPI_DEBUGFACILITIES
283 bool "Maintainer debug facilities"
284 depends on THINKPAD_ACPI
287 Enables extra stuff in the thinkpad-acpi which is completely useless
288 for normal use. Read the driver source to find out what it does.
290 Say N here, unless you were told by a kernel maintainer to do
293 config THINKPAD_ACPI_DEBUG
294 bool "Verbose debug mode"
295 depends on THINKPAD_ACPI
298 Enables extra debugging information, at the expense of a slightly
299 increase in driver size.
301 If you are not sure, say N here.
303 config THINKPAD_ACPI_UNSAFE_LEDS
304 bool "Allow control of important LEDs (unsafe)"
305 depends on THINKPAD_ACPI
308 Overriding LED state on ThinkPads can mask important
309 firmware alerts (like critical battery condition), or misled
310 the user into damaging the hardware (undocking or ejecting
311 the bay while buses are still active), etc.
313 LED control on the ThinkPad is write-only (with very few
314 exceptions on very ancient models), which makes it
315 impossible to know beforehand if important information will
316 be lost when one changes LED state.
318 Users that know what they are doing can enable this option
319 and the driver will allow control of every LED, including
320 the ones on the dock stations.
322 Never enable this option on a distribution kernel.
324 Say N here, unless you are building a kernel for your own
325 use, and need to control the important firmware LEDs.
327 config THINKPAD_ACPI_VIDEO
328 bool "Video output control support"
329 depends on THINKPAD_ACPI
332 Allows the thinkpad_acpi driver to provide an interface to control
333 the various video output ports.
335 This feature often won't work well, depending on ThinkPad model,
336 display state, video output devices in use, whether there is a X
337 server running, phase of the moon, and the current mood of
338 Schroedinger's cat. If you can use X.org's RandR to control
339 your ThinkPad's video output ports instead of this feature,
340 don't think twice: do it and say N here to save memory and avoid
341 bad interactions with X.org.
343 NOTE: access to this feature is limited to processes with the
344 CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
345 where it interacts badly with X.org.
347 If you are not sure, say Y here but do try to check if you could
348 be using X.org RandR instead.
350 config THINKPAD_ACPI_HOTKEY_POLL
351 bool "Support NVRAM polling for hot keys"
352 depends on THINKPAD_ACPI
355 Some thinkpad models benefit from NVRAM polling to detect a few of
356 the hot key press events. If you know your ThinkPad model does not
357 need to do NVRAM polling to support any of the hot keys you use,
358 unselecting this option will save about 1kB of memory.
360 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
361 unlikely to need NVRAM polling in their latest BIOS versions.
363 NVRAM polling can detect at most the following keys: ThinkPad/Access
364 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
365 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
367 If you are not sure, say Y here. The driver enables polling only if
368 it is strictly necessary to do so.
371 tristate "Thermal Management driver for Intel menlow platform"
372 depends on ACPI_THERMAL
375 ACPI thermal management enhancement driver on
376 Intel Menlow platform.
381 tristate "Eee PC Hotkey Driver (EXPERIMENTAL)"
384 depends on EXPERIMENTAL
385 depends on RFKILL || RFKILL = n
386 depends on HOTPLUG_PCI
387 select BACKLIGHT_CLASS_DEVICE
391 select INPUT_SPARSEKMAP
393 This driver supports the Fn-Fx keys on Eee PC laptops.
395 It also gives access to some extra laptop functionalities like
396 Bluetooth, backlight and allows powering on/off some other
399 If you have an Eee PC laptop, say Y or M here.
402 tristate "Eee PC WMI Hotkey Driver (EXPERIMENTAL)"
405 depends on EXPERIMENTAL
406 depends on BACKLIGHT_CLASS_DEVICE
407 select INPUT_SPARSEKMAP
409 Say Y here if you want to support WMI-based hotkeys on Eee PC laptops.
411 To compile this driver as a module, choose M here: the module will
418 This driver adds support for the ACPI-WMI (Windows Management
419 Instrumentation) mapper device (PNP0C14) found on some systems.
421 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
422 ACPI firmware to userspace - this is done through various vendor
423 defined methods and data blocks in a PNP0C14 device, which are then
424 made available for userspace to call.
426 The implementation of this in Linux currently only exposes this to
427 other kernel space drivers.
429 This driver is a required dependency to build the firmware specific
430 drivers needed on many machines, including Acer and HP laptops.
432 It is safe to enable this driver even if your DSDT doesn't define
433 any ACPI-WMI devices.
436 tristate "MSI WMI extras"
439 depends on BACKLIGHT_CLASS_DEVICE
440 select INPUT_SPARSEKMAP
442 Say Y here if you want to support WMI-based hotkeys on MSI laptops.
444 To compile this driver as a module, choose M here: the module will
448 tristate "ASUS/Medion Laptop Extras (DEPRECATED)"
450 select BACKLIGHT_CLASS_DEVICE
452 This driver provides support for extra features of ACPI-compatible
453 ASUS laptops. As some of Medion laptops are made by ASUS, it may also
454 support some Medion laptops (such as 9675 for example). It makes all
455 the extra buttons generate standard ACPI events that go through
456 /proc/acpi/events, and (on some models) adds support for changing the
457 display brightness and output, switching the LCD backlight on and off,
458 and most importantly, allows you to blink those fancy LEDs intended
459 for reporting mail and wireless status.
461 Note: display switching code is currently considered EXPERIMENTAL,
462 toying with these values may even lock your machine.
464 All settings are changed via /proc/acpi/asus directory entries. Owner
465 and group for these entries can be set with asus_uid and asus_gid
468 More information and a userspace daemon for handling the extra buttons
469 at <http://acpi4asus.sf.net>.
471 If you have an ACPI-compatible ASUS laptop, say Y or M here. This
472 driver is still under development, so if your laptop is unsupported or
473 something works not quite as expected, please use the mailing list
474 available on the above page (acpi4asus-user@lists.sourceforge.net).
476 NOTE: This driver is deprecated and will probably be removed soon,
477 use asus-laptop instead.
479 config TOPSTAR_LAPTOP
480 tristate "Topstar Laptop Extras"
483 select INPUT_SPARSEKMAP
485 This driver adds support for hotkeys found on Topstar laptops.
487 If you have a Topstar laptop, say Y or M here.
490 tristate "Toshiba Laptop Extras"
492 depends on LEDS_CLASS
494 depends on BACKLIGHT_CLASS_DEVICE
496 depends on RFKILL || RFKILL = n
499 This driver adds support for access to certain system settings
500 on "legacy free" Toshiba laptops. These laptops can be recognized by
501 their lack of a BIOS setup menu and APM support.
503 On these machines, all system configuration is handled through the
504 ACPI. This driver is required for access to controls not covered
505 by the general ACPI drivers, such as LCD brightness, video output,
508 This driver differs from the non-ACPI Toshiba laptop driver (located
509 under "Processor type and features") in several aspects.
510 Configuration is accessed by reading and writing text files in the
511 /proc tree instead of by program interface to /dev. Furthermore, no
512 power management functions are exposed, as those are handled by the
513 general ACPI drivers.
515 More information about this driver is available at
516 <http://memebeam.org/toys/ToshibaAcpiDriver>.
518 If you have a legacy free Toshiba laptop (such as the Libretto L1
521 config TOSHIBA_BT_RFKILL
522 tristate "Toshiba Bluetooth RFKill switch support"
525 This driver adds support for Bluetooth events for the RFKill
526 switch on modern Toshiba laptops with full ACPI support and
529 This driver handles RFKill events for the TOS6205 Bluetooth,
530 and re-enables it when the switch is set back to the 'on'
533 If you have a modern Toshiba laptop with a Bluetooth and an
534 RFKill switch (such as the Portege R500), say Y.
537 tristate "CMPC Laptop Extras"
538 depends on X86 && ACPI
539 depends on RFKILL || RFKILL=n
541 select BACKLIGHT_CLASS_DEVICE
544 Support for Intel Classmate PC ACPI devices, including some
545 keys as input device, backlight device, tablet and accelerometer
549 bool "Intel SCU IPC Support"
553 IPC is used to bridge the communications between kernel and SCU on
554 some embedded Intel x86 platforms. This is not needed for PC-type
557 config GPIO_INTEL_PMIC
558 bool "Intel PMIC GPIO support"
559 depends on INTEL_SCU_IPC && GPIOLIB
561 Say Y here to support GPIO via the SCU IPC interface
562 on Intel MID platforms.
565 bool "Restricted Access Region Register Driver"
566 depends on PCI && X86_MRST
569 This driver allows other kernel drivers access to the
570 contents of the restricted access region control registers.
572 The restricted access region control registers
573 (rar_registers) are used to pass address and
574 locking information on restricted access regions
575 to other drivers that use restricted access regions.
577 The restricted access regions are regions of memory
578 on the Intel MID Platform that are not accessible to
579 the x86 processor, but are accessible to dedicated
580 processors on board peripheral devices.
582 The purpose of the restricted access regions is to
583 protect sensitive data from compromise by unauthorized
584 programs running on the x86 processor.
587 tristate "Intel Intelligent Power Sharing"
590 Intel Calpella platforms support dynamic power sharing between the
591 CPU and GPU, maximizing performance in a given TDP. This driver,
592 along with the CPU frequency and i915 drivers, provides that
593 functionality. If in doubt, say Y here; it will only load on
