62 depends on RFKILL || RFKILL = n
63 select INPUT_SPARSEKMAP
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>.
74 If you have an ACPI-compatible ASUS laptop, say Y or M here.

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

144 to read data from WMI such as docking or ambient light sensor state.
146 To compile this driver as a module, choose M here: the module will
150 tristate "MSI Laptop Extras"
152 depends on BACKLIGHT_CLASS_DEVICE
155 This is a driver for laptops built by MSI (MICRO-STAR
158 MSI MegaBook S270 (MS-1013)
159 Cytron/TCM/Medion/Tchibo MD96100/SAM2000
161 It adds support for Bluetooth, WLAN and LCD brightness control.
163 More information about this driver is available at
164 <http://0pointer.de/lennart/tchibo.html>.
166 If you have an MSI S270 laptop, say Y or M here.
168 config PANASONIC_LAPTOP
169 tristate "Panasonic Laptop Extras"
170 depends on INPUT && ACPI
171 depends on BACKLIGHT_CLASS_DEVICE
173 This driver adds support for access to backlight control and hotkeys
174 on Panasonic Let's Note laptops.
176 If you have a Panasonic Let's note laptop (such as the R1(N variant),
177 R2, R3, R5, T2, W2 and Y2 series), say Y.
180 tristate "Compal Laptop Extras"
182 depends on BACKLIGHT_CLASS_DEVICE
185 This is a driver for laptops built by Compal:
192 It adds support for Bluetooth, WLAN and LCD brightness control.
194 If you have an Compal FL9x/IFL9x/FT00 laptop, say Y or M here.
197 tristate "Sony Laptop Extras"
199 select BACKLIGHT_CLASS_DEVICE
203 This mini-driver drives the SNC and SPIC devices present in the ACPI
204 BIOS of the Sony Vaio laptops.
206 It gives access to some extra laptop functionalities like Bluetooth,
207 screen brightness control, Fn keys and allows powering on/off some
210 Read <file:Documentation/laptops/sony-laptop.txt> for more information.
213 bool "Sonypi compatibility"
214 depends on SONY_LAPTOP
216 Build the sonypi driver compatibility code into the sony-laptop driver.
219 tristate "ThinkPad ACPI Laptop Extras"
222 depends on RFKILL || RFKILL = n
223 select BACKLIGHT_LCD_SUPPORT
224 select BACKLIGHT_CLASS_DEVICE
230 This is a driver for the IBM and Lenovo ThinkPad laptops. It adds
231 support for Fn-Fx key combinations, Bluetooth control, video
232 output switching, ThinkLight control, UltraBay eject and more.
233 For more information about this driver see
234 <file:Documentation/laptops/thinkpad-acpi.txt> and
235 <http://ibm-acpi.sf.net/> .
237 This driver was formerly known as ibm-acpi.
239 Extra functionality will be available if the rfkill (CONFIG_RFKILL)
240 and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
241 Note that if you want ThinkPad-ACPI to be built-in instead of
242 modular, ALSA and rfkill will also have to be built-in.
244 If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.
246 config THINKPAD_ACPI_ALSA_SUPPORT
247 bool "Console audio control ALSA interface"
248 depends on THINKPAD_ACPI
250 depends on SND = y || THINKPAD_ACPI = SND
253 Enables monitoring of the built-in console audio output control
254 (headphone and speakers), which is operated by the mute and (in
255 some ThinkPad models) volume hotkeys.
257 If this option is enabled, ThinkPad-ACPI will export an ALSA card
258 with a single read-only mixer control, which should be used for
259 on-screen-display feedback purposes by the Desktop Environment.
261 Optionally, the driver will also allow software control (the
262 ALSA mixer will be made read-write). Please refer to the driver
263 documentation for details.
265 All IBM models have both volume and mute control. Newer Lenovo
266 models only have mute control (the volume hotkeys are just normal
267 keys and volume control is done through the main HDA mixer).
269 config THINKPAD_ACPI_DEBUGFACILITIES
270 bool "Maintainer debug facilities"
271 depends on THINKPAD_ACPI
274 Enables extra stuff in the thinkpad-acpi which is completely useless
275 for normal use. Read the driver source to find out what it does.
277 Say N here, unless you were told by a kernel maintainer to do
280 config THINKPAD_ACPI_DEBUG
281 bool "Verbose debug mode"
282 depends on THINKPAD_ACPI
285 Enables extra debugging information, at the expense of a slightly
286 increase in driver size.
288 If you are not sure, say N here.
290 config THINKPAD_ACPI_UNSAFE_LEDS
291 bool "Allow control of important LEDs (unsafe)"
292 depends on THINKPAD_ACPI
295 Overriding LED state on ThinkPads can mask important
296 firmware alerts (like critical battery condition), or misled
297 the user into damaging the hardware (undocking or ejecting
298 the bay while buses are still active), etc.
300 LED control on the ThinkPad is write-only (with very few
301 exceptions on very ancient models), which makes it
302 impossible to know beforehand if important information will
303 be lost when one changes LED state.
305 Users that know what they are doing can enable this option
306 and the driver will allow control of every LED, including
307 the ones on the dock stations.
309 Never enable this option on a distribution kernel.
311 Say N here, unless you are building a kernel for your own
312 use, and need to control the important firmware LEDs.
314 config THINKPAD_ACPI_VIDEO
315 bool "Video output control support"
316 depends on THINKPAD_ACPI
319 Allows the thinkpad_acpi driver to provide an interface to control
320 the various video output ports.
322 This feature often won't work well, depending on ThinkPad model,
323 display state, video output devices in use, whether there is a X
324 server running, phase of the moon, and the current mood of
325 Schroedinger's cat. If you can use X.org's RandR to control
326 your ThinkPad's video output ports instead of this feature,
327 don't think twice: do it and say N here to save memory and avoid
328 bad interactions with X.org.
330 NOTE: access to this feature is limited to processes with the
331 CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
332 where it interacts badly with X.org.
334 If you are not sure, say Y here but do try to check if you could
335 be using X.org RandR instead.
337 config THINKPAD_ACPI_HOTKEY_POLL
338 bool "Support NVRAM polling for hot keys"
339 depends on THINKPAD_ACPI
342 Some thinkpad models benefit from NVRAM polling to detect a few of
343 the hot key press events. If you know your ThinkPad model does not
344 need to do NVRAM polling to support any of the hot keys you use,
345 unselecting this option will save about 1kB of memory.
347 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
348 unlikely to need NVRAM polling in their latest BIOS versions.
350 NVRAM polling can detect at most the following keys: ThinkPad/Access
351 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
352 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
354 If you are not sure, say Y here. The driver enables polling only if
355 it is strictly necessary to do so.
358 tristate "Thermal Management driver for Intel menlow platform"
359 depends on ACPI_THERMAL
362 ACPI thermal management enhancement driver on
363 Intel Menlow platform.
368 tristate "Eee PC Hotkey Driver (EXPERIMENTAL)"
371 depends on EXPERIMENTAL
372 depends on RFKILL || RFKILL = n
373 depends on HOTPLUG_PCI
374 select BACKLIGHT_CLASS_DEVICE
378 select INPUT_SPARSEKMAP
380 This driver supports the Fn-Fx keys on Eee PC laptops.
382 It also gives access to some extra laptop functionalities like
383 Bluetooth, backlight and allows powering on/off some other
386 If you have an Eee PC laptop, say Y or M here.
389 tristate "Eee PC WMI Hotkey Driver (EXPERIMENTAL)"
392 depends on EXPERIMENTAL
393 depends on BACKLIGHT_CLASS_DEVICE
394 select INPUT_SPARSEKMAP
396 Say Y here if you want to support WMI-based hotkeys on Eee PC laptops.
398 To compile this driver as a module, choose M here: the module will
405 This driver adds support for the ACPI-WMI (Windows Management
406 Instrumentation) mapper device (PNP0C14) found on some systems.
408 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
409 ACPI firmware to userspace - this is done through various vendor
410 defined methods and data blocks in a PNP0C14 device, which are then
411 made available for userspace to call.
413 The implementation of this in Linux currently only exposes this to
414 other kernel space drivers.
416 This driver is a required dependency to build the firmware specific
417 drivers needed on many machines, including Acer and HP laptops.
419 It is safe to enable this driver even if your DSDT doesn't define
420 any ACPI-WMI devices.
423 tristate "MSI WMI extras"
426 depends on BACKLIGHT_CLASS_DEVICE
427 select INPUT_SPARSEKMAP
429 Say Y here if you want to support WMI-based hotkeys on MSI laptops.
431 To compile this driver as a module, choose M here: the module will
435 tristate "ASUS/Medion Laptop Extras (DEPRECATED)"
437 select BACKLIGHT_CLASS_DEVICE
439 This driver provides support for extra features of ACPI-compatible
440 ASUS laptops. As some of Medion laptops are made by ASUS, it may also
441 support some Medion laptops (such as 9675 for example). It makes all
442 the extra buttons generate standard ACPI events that go through
443 /proc/acpi/events, and (on some models) adds support for changing the
444 display brightness and output, switching the LCD backlight on and off,
445 and most importantly, allows you to blink those fancy LEDs intended
446 for reporting mail and wireless status.
448 Note: display switching code is currently considered EXPERIMENTAL,
449 toying with these values may even lock your machine.
451 All settings are changed via /proc/acpi/asus directory entries. Owner
452 and group for these entries can be set with asus_uid and asus_gid
455 More information and a userspace daemon for handling the extra buttons
456 at <http://acpi4asus.sf.net>.
458 If you have an ACPI-compatible ASUS laptop, say Y or M here. This
459 driver is still under development, so if your laptop is unsupported or
460 something works not quite as expected, please use the mailing list
461 available on the above page (acpi4asus-user@lists.sourceforge.net).
463 NOTE: This driver is deprecated and will probably be removed soon,
464 use asus-laptop instead.
466 config TOPSTAR_LAPTOP
467 tristate "Topstar Laptop Extras"
471 This driver adds support for hotkeys found on Topstar laptops.
473 If you have a Topstar laptop, say Y or M here.
476 tristate "Toshiba Laptop Extras"
479 depends on RFKILL || RFKILL = n
481 select BACKLIGHT_CLASS_DEVICE
483 This driver adds support for access to certain system settings
484 on "legacy free" Toshiba laptops. These laptops can be recognized by
485 their lack of a BIOS setup menu and APM support.
487 On these machines, all system configuration is handled through the
488 ACPI. This driver is required for access to controls not covered
489 by the general ACPI drivers, such as LCD brightness, video output,
492 This driver differs from the non-ACPI Toshiba laptop driver (located
493 under "Processor type and features") in several aspects.
494 Configuration is accessed by reading and writing text files in the
495 /proc tree instead of by program interface to /dev. Furthermore, no
496 power management functions are exposed, as those are handled by the
497 general ACPI drivers.
499 More information about this driver is available at
500 <http://memebeam.org/toys/ToshibaAcpiDriver>.
502 If you have a legacy free Toshiba laptop (such as the Libretto L1
505 config TOSHIBA_BT_RFKILL
506 tristate "Toshiba Bluetooth RFKill switch support"
509 This driver adds support for Bluetooth events for the RFKill
510 switch on modern Toshiba laptops with full ACPI support and
513 This driver handles RFKill events for the TOS6205 Bluetooth,
514 and re-enables it when the switch is set back to the 'on'
517 If you have a modern Toshiba laptop with a Bluetooth and an
518 RFKill switch (such as the Portege R500), say Y.
521 tristate "CMPC Laptop Extras"
522 depends on X86 && ACPI
523 depends on RFKILL || RFKILL=n
525 select BACKLIGHT_CLASS_DEVICE
528 Support for Intel Classmate PC ACPI devices, including some
529 keys as input device, backlight device, tablet and accelerometer
