65 This is the new Linux driver for Asus laptops. It may also support some
66 MEDION, JVC or VICTOR laptops. It makes all the extra buttons generate
67 standard ACPI events and input events. It also adds
68 support for video output switching, LCD backlight control, Bluetooth and
69 Wlan control, and most importantly, allows you to blink those fancy LEDs.
71 For more information and a userspace daemon for handling the extra
72 buttons see <http://acpi4asus.sf.net>.

100 config FUJITSU_LAPTOP
101 tristate "Fujitsu Laptop Extras"
104 depends on BACKLIGHT_CLASS_DEVICE
105 depends on LEDS_CLASS || LEDS_CLASS=n
107 This is a driver for laptops built by Fujitsu:
109 * P2xxx/P5xxx/S6xxx/S7xxx series Lifebooks
110 * Possibly other Fujitsu laptop models
111 * Tested with S6410 and S7020
113 It adds support for LCD brightness control and some hotkeys.
115 If you have a Fujitsu laptop, say Y or M here.
117 config FUJITSU_LAPTOP_DEBUG
118 bool "Verbose debug mode for Fujitsu Laptop Extras"
119 depends on FUJITSU_LAPTOP
122 Enables extra debug output from the fujitsu extras driver, at the
123 expense of a slight increase in driver size.
125 If you are not sure, say N here.
128 tristate "HP Compaq TC1100 Tablet WMI Extras (EXPERIMENTAL)"
130 depends on EXPERIMENTAL
134 This is a driver for the WMI extensions (wireless and bluetooth power
135 control) of the HP Compaq TC1100 tablet.
138 tristate "HP WMI extras"
141 depends on RFKILL || RFKILL = n
143 Say Y here if you want to support WMI-based hotkeys on HP laptops and
144 to read data from WMI such as docking or ambient light sensor state.

150 tristate "MSI Laptop Extras"
152 depends on BACKLIGHT_CLASS_DEVICE
154 depends on SERIO_I8042
156 This is a driver for laptops built by MSI (MICRO-STAR
159 MSI MegaBook S270 (MS-1013)
160 Cytron/TCM/Medion/Tchibo MD96100/SAM2000
162 It adds support for Bluetooth, WLAN and LCD brightness control.
164 More information about this driver is available at
165 <http://0pointer.de/lennart/tchibo.html>.
167 If you have an MSI S270 laptop, say Y or M here.
169 config PANASONIC_LAPTOP
170 tristate "Panasonic Laptop Extras"
171 depends on INPUT && ACPI
172 depends on BACKLIGHT_CLASS_DEVICE
174 This driver adds support for access to backlight control and hotkeys
175 on Panasonic Let's Note laptops.
177 If you have a Panasonic Let's note laptop (such as the R1(N variant),
178 R2, R3, R5, T2, W2 and Y2 series), say Y.
181 tristate "Compal Laptop Extras"
183 depends on BACKLIGHT_CLASS_DEVICE
187 This is a driver for laptops built by Compal:
194 It adds support for Bluetooth, WLAN and LCD brightness control.
196 If you have an Compal FL9x/IFL9x/FT00 laptop, say Y or M here.
199 tristate "Sony Laptop Extras"
201 select BACKLIGHT_CLASS_DEVICE
205 This mini-driver drives the SNC and SPIC devices present in the ACPI
206 BIOS of the Sony Vaio laptops.
208 It gives access to some extra laptop functionalities like Bluetooth,
209 screen brightness control, Fn keys and allows powering on/off some
212 Read <file:Documentation/laptops/sony-laptop.txt> for more information.
215 bool "Sonypi compatibility"
216 depends on SONY_LAPTOP
218 Build the sonypi driver compatibility code into the sony-laptop driver.
221 tristate "ThinkPad ACPI Laptop Extras"
224 depends on RFKILL || RFKILL = n
225 select BACKLIGHT_LCD_SUPPORT
226 select BACKLIGHT_CLASS_DEVICE
232 This is a driver for the IBM and Lenovo ThinkPad laptops. It adds
233 support for Fn-Fx key combinations, Bluetooth control, video
234 output switching, ThinkLight control, UltraBay eject and more.
235 For more information about this driver see
236 <file:Documentation/laptops/thinkpad-acpi.txt> and
237 <http://ibm-acpi.sf.net/> .
239 This driver was formerly known as ibm-acpi.
241 Extra functionality will be available if the rfkill (CONFIG_RFKILL)
242 and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
243 Note that if you want ThinkPad-ACPI to be built-in instead of
244 modular, ALSA and rfkill will also have to be built-in.
246 If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.
248 config THINKPAD_ACPI_ALSA_SUPPORT
249 bool "Console audio control ALSA interface"
250 depends on THINKPAD_ACPI
252 depends on SND = y || THINKPAD_ACPI = SND
255 Enables monitoring of the built-in console audio output control
256 (headphone and speakers), which is operated by the mute and (in
257 some ThinkPad models) volume hotkeys.
259 If this option is enabled, ThinkPad-ACPI will export an ALSA card
260 with a single read-only mixer control, which should be used for
261 on-screen-display feedback purposes by the Desktop Environment.
263 Optionally, the driver will also allow software control (the
264 ALSA mixer will be made read-write). Please refer to the driver
265 documentation for details.
267 All IBM models have both volume and mute control. Newer Lenovo
268 models only have mute control (the volume hotkeys are just normal
269 keys and volume control is done through the main HDA mixer).
271 config THINKPAD_ACPI_DEBUGFACILITIES
272 bool "Maintainer debug facilities"
273 depends on THINKPAD_ACPI
276 Enables extra stuff in the thinkpad-acpi which is completely useless
277 for normal use. Read the driver source to find out what it does.
279 Say N here, unless you were told by a kernel maintainer to do
282 config THINKPAD_ACPI_DEBUG
283 bool "Verbose debug mode"
284 depends on THINKPAD_ACPI
287 Enables extra debugging information, at the expense of a slightly
288 increase in driver size.
290 If you are not sure, say N here.
292 config THINKPAD_ACPI_UNSAFE_LEDS
293 bool "Allow control of important LEDs (unsafe)"
294 depends on THINKPAD_ACPI
297 Overriding LED state on ThinkPads can mask important
298 firmware alerts (like critical battery condition), or misled
299 the user into damaging the hardware (undocking or ejecting
300 the bay while buses are still active), etc.
302 LED control on the ThinkPad is write-only (with very few
303 exceptions on very ancient models), which makes it
304 impossible to know beforehand if important information will
305 be lost when one changes LED state.
307 Users that know what they are doing can enable this option
308 and the driver will allow control of every LED, including
309 the ones on the dock stations.
311 Never enable this option on a distribution kernel.
313 Say N here, unless you are building a kernel for your own
314 use, and need to control the important firmware LEDs.
316 config THINKPAD_ACPI_VIDEO
317 bool "Video output control support"
318 depends on THINKPAD_ACPI
321 Allows the thinkpad_acpi driver to provide an interface to control
322 the various video output ports.
324 This feature often won't work well, depending on ThinkPad model,
325 display state, video output devices in use, whether there is a X
326 server running, phase of the moon, and the current mood of
327 Schroedinger's cat. If you can use X.org's RandR to control
328 your ThinkPad's video output ports instead of this feature,
329 don't think twice: do it and say N here to save memory and avoid
330 bad interactions with X.org.
332 NOTE: access to this feature is limited to processes with the
333 CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
334 where it interacts badly with X.org.
336 If you are not sure, say Y here but do try to check if you could
337 be using X.org RandR instead.
339 config THINKPAD_ACPI_HOTKEY_POLL
340 bool "Support NVRAM polling for hot keys"
341 depends on THINKPAD_ACPI
344 Some thinkpad models benefit from NVRAM polling to detect a few of
345 the hot key press events. If you know your ThinkPad model does not
346 need to do NVRAM polling to support any of the hot keys you use,
347 unselecting this option will save about 1kB of memory.
349 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
350 unlikely to need NVRAM polling in their latest BIOS versions.
352 NVRAM polling can detect at most the following keys: ThinkPad/Access
353 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
354 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
356 If you are not sure, say Y here. The driver enables polling only if
357 it is strictly necessary to do so.
360 tristate "Thermal Management driver for Intel menlow platform"
361 depends on ACPI_THERMAL
364 ACPI thermal management enhancement driver on
365 Intel Menlow platform.
370 tristate "Eee PC Hotkey Driver (EXPERIMENTAL)"
373 depends on EXPERIMENTAL
374 depends on RFKILL || RFKILL = n
375 depends on HOTPLUG_PCI
376 select BACKLIGHT_CLASS_DEVICE
380 select INPUT_SPARSEKMAP
382 This driver supports the Fn-Fx keys on Eee PC laptops.
384 It also gives access to some extra laptop functionalities like
385 Bluetooth, backlight and allows powering on/off some other
388 If you have an Eee PC laptop, say Y or M here.
391 tristate "Eee PC WMI Hotkey Driver (EXPERIMENTAL)"
394 depends on EXPERIMENTAL
395 depends on BACKLIGHT_CLASS_DEVICE
396 select INPUT_SPARSEKMAP
398 Say Y here if you want to support WMI-based hotkeys on Eee PC laptops.
400 To compile this driver as a module, choose M here: the module will
407 This driver adds support for the ACPI-WMI (Windows Management
408 Instrumentation) mapper device (PNP0C14) found on some systems.
410 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
411 ACPI firmware to userspace - this is done through various vendor
412 defined methods and data blocks in a PNP0C14 device, which are then
413 made available for userspace to call.
415 The implementation of this in Linux currently only exposes this to
416 other kernel space drivers.
418 This driver is a required dependency to build the firmware specific
419 drivers needed on many machines, including Acer and HP laptops.
421 It is safe to enable this driver even if your DSDT doesn't define
422 any ACPI-WMI devices.
425 tristate "MSI WMI extras"
428 depends on BACKLIGHT_CLASS_DEVICE
429 select INPUT_SPARSEKMAP
431 Say Y here if you want to support WMI-based hotkeys on MSI laptops.
433 To compile this driver as a module, choose M here: the module will
437 tristate "ASUS/Medion Laptop Extras (DEPRECATED)"
439 select BACKLIGHT_CLASS_DEVICE
441 This driver provides support for extra features of ACPI-compatible
442 ASUS laptops. As some of Medion laptops are made by ASUS, it may also
443 support some Medion laptops (such as 9675 for example). It makes all
444 the extra buttons generate standard ACPI events that go through
445 /proc/acpi/events, and (on some models) adds support for changing the
446 display brightness and output, switching the LCD backlight on and off,
447 and most importantly, allows you to blink those fancy LEDs intended
448 for reporting mail and wireless status.
450 Note: display switching code is currently considered EXPERIMENTAL,
451 toying with these values may even lock your machine.
453 All settings are changed via /proc/acpi/asus directory entries. Owner
454 and group for these entries can be set with asus_uid and asus_gid
457 More information and a userspace daemon for handling the extra buttons
458 at <http://acpi4asus.sf.net>.
460 If you have an ACPI-compatible ASUS laptop, say Y or M here. This
461 driver is still under development, so if your laptop is unsupported or
462 something works not quite as expected, please use the mailing list
463 available on the above page (acpi4asus-user@lists.sourceforge.net).
465 NOTE: This driver is deprecated and will probably be removed soon,
466 use asus-laptop instead.
468 config TOPSTAR_LAPTOP
469 tristate "Topstar Laptop Extras"
473 This driver adds support for hotkeys found on Topstar laptops.
475 If you have a Topstar laptop, say Y or M here.
478 tristate "Toshiba Laptop Extras"
481 depends on RFKILL || RFKILL = n
483 select BACKLIGHT_CLASS_DEVICE
485 This driver adds support for access to certain system settings
486 on "legacy free" Toshiba laptops. These laptops can be recognized by
487 their lack of a BIOS setup menu and APM support.
489 On these machines, all system configuration is handled through the
490 ACPI. This driver is required for access to controls not covered
491 by the general ACPI drivers, such as LCD brightness, video output,
494 This driver differs from the non-ACPI Toshiba laptop driver (located
495 under "Processor type and features") in several aspects.
496 Configuration is accessed by reading and writing text files in the
497 /proc tree instead of by program interface to /dev. Furthermore, no
498 power management functions are exposed, as those are handled by the
499 general ACPI drivers.
501 More information about this driver is available at
502 <http://memebeam.org/toys/ToshibaAcpiDriver>.
504 If you have a legacy free Toshiba laptop (such as the Libretto L1
507 config TOSHIBA_BT_RFKILL
508 tristate "Toshiba Bluetooth RFKill switch support"
511 This driver adds support for Bluetooth events for the RFKill
512 switch on modern Toshiba laptops with full ACPI support and
515 This driver handles RFKill events for the TOS6205 Bluetooth,
516 and re-enables it when the switch is set back to the 'on'
519 If you have a modern Toshiba laptop with a Bluetooth and an
520 RFKill switch (such as the Portege R500), say Y.
523 tristate "CMPC Laptop Extras"
524 depends on X86 && ACPI
525 depends on RFKILL || RFKILL=n
527 select BACKLIGHT_CLASS_DEVICE
530 Support for Intel Classmate PC ACPI devices, including some
531 keys as input device, backlight device, tablet and accelerometer
535 bool "Intel SCU IPC Support"
539 IPC is used to bridge the communications between kernel and SCU on
540 some embedded Intel x86 platforms. This is not needed for PC-type
543 config GPIO_INTEL_PMIC
544 bool "Intel PMIC GPIO support"
545 depends on INTEL_SCU_IPC && GPIOLIB
547 Say Y here to support GPIO via the SCU IPC interface
548 on Intel MID platforms.
551 bool "Restricted Access Region Register Driver"
552 depends on PCI && X86_MRST
555 This driver allows other kernel drivers access to the
556 contents of the restricted access region control registers.
558 The restricted access region control registers
559 (rar_registers) are used to pass address and
560 locking information on restricted access regions
561 to other drivers that use restricted access regions.
563 The restricted access regions are regions of memory
564 on the Intel MID Platform that are not accessible to
565 the x86 processor, but are accessible to dedicated
566 processors on board peripheral devices.
568 The purpose of the restricted access regions is to
569 protect sensitive data from compromise by unauthorized
570 programs running on the x86 processor.
573 tristate "Intel Intelligent Power Sharing"
576 Intel Calpella platforms support dynamic power sharing between the
577 CPU and GPU, maximizing performance in a given TDP. This driver,
578 along with the CPU frequency and i915 drivers, provides that
579 functionality. If in doubt, say Y here; it will only load on
