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>.

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.
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
154 This is a driver for laptops built by MSI (MICRO-STAR
157 MSI MegaBook S270 (MS-1013)
158 Cytron/TCM/Medion/Tchibo MD96100/SAM2000
160 It adds support for Bluetooth, WLAN and LCD brightness control.
162 More information about this driver is available at
163 <http://0pointer.de/lennart/tchibo.html>.
165 If you have an MSI S270 laptop, say Y or M here.
167 config PANASONIC_LAPTOP
168 tristate "Panasonic Laptop Extras"
169 depends on INPUT && ACPI
170 depends on BACKLIGHT_CLASS_DEVICE
172 This driver adds support for access to backlight control and hotkeys
173 on Panasonic Let's Note laptops.
175 If you have a Panasonic Let's note laptop (such as the R1(N variant),
176 R2, R3, R5, T2, W2 and Y2 series), say Y.
179 tristate "Compal Laptop Extras"
181 depends on BACKLIGHT_CLASS_DEVICE
183 This is a driver for laptops built by Compal:
190 It adds support for Bluetooth, WLAN and LCD brightness control.
192 If you have an Compal FL9x/IFL9x/FT00 laptop, say Y or M here.
195 tristate "Sony Laptop Extras"
197 select BACKLIGHT_CLASS_DEVICE
201 This mini-driver drives the SNC and SPIC devices present in the ACPI
202 BIOS of the Sony Vaio laptops.
204 It gives access to some extra laptop functionalities like Bluetooth,
205 screen brightness control, Fn keys and allows powering on/off some
208 Read <file:Documentation/laptops/sony-laptop.txt> for more information.
211 bool "Sonypi compatibility"
212 depends on SONY_LAPTOP
214 Build the sonypi driver compatibility code into the sony-laptop driver.
217 tristate "ThinkPad ACPI Laptop Extras"
220 depends on RFKILL || RFKILL = n
221 select BACKLIGHT_LCD_SUPPORT
222 select BACKLIGHT_CLASS_DEVICE
228 This is a driver for the IBM and Lenovo ThinkPad laptops. It adds
229 support for Fn-Fx key combinations, Bluetooth control, video
230 output switching, ThinkLight control, UltraBay eject and more.
231 For more information about this driver see
232 <file:Documentation/laptops/thinkpad-acpi.txt> and
233 <http://ibm-acpi.sf.net/> .
235 This driver was formerly known as ibm-acpi.
237 Extra functionality will be available if the rfkill (CONFIG_RFKILL)
238 and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
239 Note that if you want ThinkPad-ACPI to be built-in instead of
240 modular, ALSA and rfkill will also have to be built-in.
242 If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.
244 config THINKPAD_ACPI_ALSA_SUPPORT
245 bool "Console audio control ALSA interface"
246 depends on THINKPAD_ACPI
248 depends on SND = y || THINKPAD_ACPI = SND
251 Enables monitoring of the built-in console audio output control
252 (headphone and speakers), which is operated by the mute and (in
253 some ThinkPad models) volume hotkeys.
255 If this option is enabled, ThinkPad-ACPI will export an ALSA card
256 with a single read-only mixer control, which should be used for
257 on-screen-display feedback purposes by the Desktop Environment.
259 Optionally, the driver will also allow software control (the
260 ALSA mixer will be made read-write). Please refer to the driver
261 documentation for details.
263 All IBM models have both volume and mute control. Newer Lenovo
264 models only have mute control (the volume hotkeys are just normal
265 keys and volume control is done through the main HDA mixer).
267 config THINKPAD_ACPI_DEBUGFACILITIES
268 bool "Maintainer debug facilities"
269 depends on THINKPAD_ACPI
272 Enables extra stuff in the thinkpad-acpi which is completely useless
273 for normal use. Read the driver source to find out what it does.
275 Say N here, unless you were told by a kernel maintainer to do
278 config THINKPAD_ACPI_DEBUG
279 bool "Verbose debug mode"
280 depends on THINKPAD_ACPI
283 Enables extra debugging information, at the expense of a slightly
284 increase in driver size.
286 If you are not sure, say N here.
288 config THINKPAD_ACPI_UNSAFE_LEDS
289 bool "Allow control of important LEDs (unsafe)"
290 depends on THINKPAD_ACPI
293 Overriding LED state on ThinkPads can mask important
294 firmware alerts (like critical battery condition), or misled
295 the user into damaging the hardware (undocking or ejecting
296 the bay while buses are still active), etc.
298 LED control on the ThinkPad is write-only (with very few
299 exceptions on very ancient models), which makes it
300 impossible to know beforehand if important information will
301 be lost when one changes LED state.
303 Users that know what they are doing can enable this option
304 and the driver will allow control of every LED, including
305 the ones on the dock stations.
307 Never enable this option on a distribution kernel.
309 Say N here, unless you are building a kernel for your own
310 use, and need to control the important firmware LEDs.
312 config THINKPAD_ACPI_VIDEO
313 bool "Video output control support"
314 depends on THINKPAD_ACPI
317 Allows the thinkpad_acpi driver to provide an interface to control
318 the various video output ports.
320 This feature often won't work well, depending on ThinkPad model,
321 display state, video output devices in use, whether there is a X
322 server running, phase of the moon, and the current mood of
323 Schroedinger's cat. If you can use X.org's RandR to control
324 your ThinkPad's video output ports instead of this feature,
325 don't think twice: do it and say N here to save memory and avoid
326 bad interactions with X.org.
328 NOTE: access to this feature is limited to processes with the
329 CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
330 where it interacts badly with X.org.
332 If you are not sure, say Y here but do try to check if you could
333 be using X.org RandR instead.
335 config THINKPAD_ACPI_HOTKEY_POLL
336 bool "Support NVRAM polling for hot keys"
337 depends on THINKPAD_ACPI
340 Some thinkpad models benefit from NVRAM polling to detect a few of
341 the hot key press events. If you know your ThinkPad model does not
342 need to do NVRAM polling to support any of the hot keys you use,
343 unselecting this option will save about 1kB of memory.
345 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
346 unlikely to need NVRAM polling in their latest BIOS versions.
348 NVRAM polling can detect at most the following keys: ThinkPad/Access
349 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
350 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
352 If you are not sure, say Y here. The driver enables polling only if
353 it is strictly necessary to do so.
356 tristate "Thermal Management driver for Intel menlow platform"
357 depends on ACPI_THERMAL
360 ACPI thermal management enhancement driver on
361 Intel Menlow platform.
366 tristate "Eee PC Hotkey Driver (EXPERIMENTAL)"
369 depends on EXPERIMENTAL
370 depends on RFKILL || RFKILL = n
371 depends on HOTPLUG_PCI
372 select BACKLIGHT_CLASS_DEVICE
376 select INPUT_SPARSEKMAP
378 This driver supports the Fn-Fx keys on Eee PC laptops.
380 It also gives access to some extra laptop functionalities like
381 Bluetooth, backlight and allows powering on/off some other
384 If you have an Eee PC laptop, say Y or M here.
391 This driver adds support for the ACPI-WMI (Windows Management
392 Instrumentation) mapper device (PNP0C14) found on some systems.
394 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
395 ACPI firmware to userspace - this is done through various vendor
396 defined methods and data blocks in a PNP0C14 device, which are then
397 made available for userspace to call.
399 The implementation of this in Linux currently only exposes this to
400 other kernel space drivers.
402 This driver is a required dependency to build the firmware specific
403 drivers needed on many machines, including Acer and HP laptops.
405 It is safe to enable this driver even if your DSDT doesn't define
406 any ACPI-WMI devices.
409 tristate "MSI WMI extras"
412 depends on BACKLIGHT_CLASS_DEVICE
413 select INPUT_SPARSEKMAP
415 Say Y here if you want to support WMI-based hotkeys on MSI laptops.
417 To compile this driver as a module, choose M here: the module will
421 tristate "ASUS/Medion Laptop Extras (DEPRECATED)"
423 select BACKLIGHT_CLASS_DEVICE
425 This driver provides support for extra features of ACPI-compatible
426 ASUS laptops. As some of Medion laptops are made by ASUS, it may also
427 support some Medion laptops (such as 9675 for example). It makes all
428 the extra buttons generate standard ACPI events that go through
429 /proc/acpi/events, and (on some models) adds support for changing the
430 display brightness and output, switching the LCD backlight on and off,
431 and most importantly, allows you to blink those fancy LEDs intended
432 for reporting mail and wireless status.
434 Note: display switching code is currently considered EXPERIMENTAL,
435 toying with these values may even lock your machine.
437 All settings are changed via /proc/acpi/asus directory entries. Owner
438 and group for these entries can be set with asus_uid and asus_gid
441 More information and a userspace daemon for handling the extra buttons
442 at <http://acpi4asus.sf.net>.
444 If you have an ACPI-compatible ASUS laptop, say Y or M here. This
445 driver is still under development, so if your laptop is unsupported or
446 something works not quite as expected, please use the mailing list
447 available on the above page (acpi4asus-user@lists.sourceforge.net).
449 NOTE: This driver is deprecated and will probably be removed soon,
450 use asus-laptop instead.
452 config TOPSTAR_LAPTOP
453 tristate "Topstar Laptop Extras"
457 This driver adds support for hotkeys found on Topstar laptops.
459 If you have a Topstar laptop, say Y or M here.
462 tristate "Toshiba Laptop Extras"
465 depends on RFKILL || RFKILL = n
467 select BACKLIGHT_CLASS_DEVICE
469 This driver adds support for access to certain system settings
470 on "legacy free" Toshiba laptops. These laptops can be recognized by
471 their lack of a BIOS setup menu and APM support.
473 On these machines, all system configuration is handled through the
474 ACPI. This driver is required for access to controls not covered
475 by the general ACPI drivers, such as LCD brightness, video output,
478 This driver differs from the non-ACPI Toshiba laptop driver (located
479 under "Processor type and features") in several aspects.
480 Configuration is accessed by reading and writing text files in the
481 /proc tree instead of by program interface to /dev. Furthermore, no
482 power management functions are exposed, as those are handled by the
483 general ACPI drivers.
485 More information about this driver is available at
486 <http://memebeam.org/toys/ToshibaAcpiDriver>.
488 If you have a legacy free Toshiba laptop (such as the Libretto L1
491 config TOSHIBA_BT_RFKILL
492 tristate "Toshiba Bluetooth RFKill switch support"
495 This driver adds support for Bluetooth events for the RFKill
496 switch on modern Toshiba laptops with full ACPI support and
499 This driver handles RFKill events for the TOS6205 Bluetooth,
500 and re-enables it when the switch is set back to the 'on'
503 If you have a modern Toshiba laptop with a Bluetooth and an
504 RFKill switch (such as the Portege R500), say Y.
507 tristate "CMPC Laptop Extras"
508 depends on X86 && ACPI
510 select BACKLIGHT_CLASS_DEVICE
513 Support for Intel Classmate PC ACPI devices, including some
514 keys as input device, backlight device, tablet and accelerometer
