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

99 tristate "Fujitsu Laptop Extras"
102 depends on BACKLIGHT_CLASS_DEVICE
103 depends on LEDS_CLASS || LEDS_CLASS=n
105 This is a driver for laptops built by Fujitsu:
107 * P2xxx/P5xxx/S6xxx/S7xxx series Lifebooks
108 * Possibly other Fujitsu laptop models
109 * Tested with S6410 and S7020
111 It adds support for LCD brightness control and some hotkeys.
113 If you have a Fujitsu laptop, say Y or M here.
115 config FUJITSU_LAPTOP_DEBUG
116 bool "Verbose debug mode for Fujitsu Laptop Extras"
117 depends on FUJITSU_LAPTOP
120 Enables extra debug output from the fujitsu extras driver, at the
121 expense of a slight increase in driver size.
123 If you are not sure, say N here.
126 tristate "HP Compaq TC1100 Tablet WMI Extras (EXPERIMENTAL)"
128 depends on EXPERIMENTAL
132 This is a driver for the WMI extensions (wireless and bluetooth power
133 control) of the HP Compaq TC1100 tablet.
136 tristate "HP WMI extras"
139 depends on RFKILL || RFKILL = n
141 Say Y here if you want to support WMI-based hotkeys on HP laptops and
142 to read data from WMI such as docking or ambient light sensor state.
144 To compile this driver as a module, choose M here: the module will
148 tristate "MSI Laptop Extras"
150 depends on BACKLIGHT_CLASS_DEVICE
152 This is a driver for laptops built by MSI (MICRO-STAR
155 MSI MegaBook S270 (MS-1013)
156 Cytron/TCM/Medion/Tchibo MD96100/SAM2000
158 It adds support for Bluetooth, WLAN and LCD brightness control.
160 More information about this driver is available at
161 <http://0pointer.de/lennart/tchibo.html>.
163 If you have an MSI S270 laptop, say Y or M here.
165 config PANASONIC_LAPTOP
166 tristate "Panasonic Laptop Extras"
167 depends on INPUT && ACPI
168 depends on BACKLIGHT_CLASS_DEVICE
170 This driver adds support for access to backlight control and hotkeys
171 on Panasonic Let's Note laptops.
173 If you have a Panasonic Let's note laptop (such as the R1(N variant),
174 R2, R3, R5, T2, W2 and Y2 series), say Y.
177 tristate "Compal Laptop Extras"
179 depends on BACKLIGHT_CLASS_DEVICE
181 This is a driver for laptops built by Compal:
188 It adds support for Bluetooth, WLAN and LCD brightness control.
190 If you have an Compal FL9x/IFL9x/FT00 laptop, say Y or M here.
193 tristate "Sony Laptop Extras"
195 select BACKLIGHT_CLASS_DEVICE
199 This mini-driver drives the SNC and SPIC devices present in the ACPI
200 BIOS of the Sony Vaio laptops.
202 It gives access to some extra laptop functionalities like Bluetooth,
203 screen brightness control, Fn keys and allows powering on/off some
206 Read <file:Documentation/laptops/sony-laptop.txt> for more information.
209 bool "Sonypi compatibility"
210 depends on SONY_LAPTOP
212 Build the sonypi driver compatibility code into the sony-laptop driver.
215 tristate "ThinkPad ACPI Laptop Extras"
218 depends on RFKILL || RFKILL = n
219 select BACKLIGHT_LCD_SUPPORT
220 select BACKLIGHT_CLASS_DEVICE
226 This is a driver for the IBM and Lenovo ThinkPad laptops. It adds
227 support for Fn-Fx key combinations, Bluetooth control, video
228 output switching, ThinkLight control, UltraBay eject and more.
229 For more information about this driver see
230 <file:Documentation/laptops/thinkpad-acpi.txt> and
231 <http://ibm-acpi.sf.net/> .
233 This driver was formerly known as ibm-acpi.
235 Extra functionality will be available if the rfkill (CONFIG_RFKILL)
236 and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
237 Note that if you want ThinkPad-ACPI to be built-in instead of
238 modular, ALSA and rfkill will also have to be built-in.
240 If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.
242 config THINKPAD_ACPI_ALSA_SUPPORT
243 bool "Console audio control ALSA interface"
244 depends on THINKPAD_ACPI
246 depends on SND = y || THINKPAD_ACPI = SND
249 Enables monitoring of the built-in console audio output control
250 (headphone and speakers), which is operated by the mute and (in
251 some ThinkPad models) volume hotkeys.
253 If this option is enabled, ThinkPad-ACPI will export an ALSA card
254 with a single read-only mixer control, which should be used for
255 on-screen-display feedback purposes by the Desktop Environment.
257 Optionally, the driver will also allow software control (the
258 ALSA mixer will be made read-write). Please refer to the driver
259 documentation for details.
261 All IBM models have both volume and mute control. Newer Lenovo
262 models only have mute control (the volume hotkeys are just normal
263 keys and volume control is done through the main HDA mixer).
265 config THINKPAD_ACPI_DEBUGFACILITIES
266 bool "Maintainer debug facilities"
267 depends on THINKPAD_ACPI
270 Enables extra stuff in the thinkpad-acpi which is completely useless
271 for normal use. Read the driver source to find out what it does.
273 Say N here, unless you were told by a kernel maintainer to do
276 config THINKPAD_ACPI_DEBUG
277 bool "Verbose debug mode"
278 depends on THINKPAD_ACPI
281 Enables extra debugging information, at the expense of a slightly
282 increase in driver size.
284 If you are not sure, say N here.
286 config THINKPAD_ACPI_UNSAFE_LEDS
287 bool "Allow control of important LEDs (unsafe)"
288 depends on THINKPAD_ACPI
291 Overriding LED state on ThinkPads can mask important
292 firmware alerts (like critical battery condition), or misled
293 the user into damaging the hardware (undocking or ejecting
294 the bay while buses are still active), etc.
296 LED control on the ThinkPad is write-only (with very few
297 exceptions on very ancient models), which makes it
298 impossible to know beforehand if important information will
299 be lost when one changes LED state.
301 Users that know what they are doing can enable this option
302 and the driver will allow control of every LED, including
303 the ones on the dock stations.
305 Never enable this option on a distribution kernel.
307 Say N here, unless you are building a kernel for your own
308 use, and need to control the important firmware LEDs.
310 config THINKPAD_ACPI_VIDEO
311 bool "Video output control support"
312 depends on THINKPAD_ACPI
315 Allows the thinkpad_acpi driver to provide an interface to control
316 the various video output ports.
318 This feature often won't work well, depending on ThinkPad model,
319 display state, video output devices in use, whether there is a X
320 server running, phase of the moon, and the current mood of
321 Schroedinger's cat. If you can use X.org's RandR to control
322 your ThinkPad's video output ports instead of this feature,
323 don't think twice: do it and say N here to save some memory.
325 If you are not sure, say Y here.
327 config THINKPAD_ACPI_HOTKEY_POLL
328 bool "Support NVRAM polling for hot keys"
329 depends on THINKPAD_ACPI
332 Some thinkpad models benefit from NVRAM polling to detect a few of
333 the hot key press events. If you know your ThinkPad model does not
334 need to do NVRAM polling to support any of the hot keys you use,
335 unselecting this option will save about 1kB of memory.
337 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
338 unlikely to need NVRAM polling in their latest BIOS versions.
340 NVRAM polling can detect at most the following keys: ThinkPad/Access
341 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
342 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
344 If you are not sure, say Y here. The driver enables polling only if
345 it is strictly necessary to do so.
348 tristate "Thermal Management driver for Intel menlow platform"
349 depends on ACPI_THERMAL
352 ACPI thermal management enhancement driver on
353 Intel Menlow platform.
358 tristate "Eee PC Hotkey Driver (EXPERIMENTAL)"
361 depends on EXPERIMENTAL
362 depends on RFKILL || RFKILL = n
363 depends on HOTPLUG_PCI
364 select BACKLIGHT_CLASS_DEVICE
368 select INPUT_SPARSEKMAP
370 This driver supports the Fn-Fx keys on Eee PC laptops.
372 It also gives access to some extra laptop functionalities like
373 Bluetooth, backlight and allows powering on/off some other
376 If you have an Eee PC laptop, say Y or M here.
383 This driver adds support for the ACPI-WMI (Windows Management
384 Instrumentation) mapper device (PNP0C14) found on some systems.
386 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
387 ACPI firmware to userspace - this is done through various vendor
388 defined methods and data blocks in a PNP0C14 device, which are then
389 made available for userspace to call.
391 The implementation of this in Linux currently only exposes this to
392 other kernel space drivers.
394 This driver is a required dependency to build the firmware specific
395 drivers needed on many machines, including Acer and HP laptops.
397 It is safe to enable this driver even if your DSDT doesn't define
398 any ACPI-WMI devices.
401 tristate "MSI WMI extras"
404 depends on BACKLIGHT_CLASS_DEVICE
405 select INPUT_SPARSEKMAP
407 Say Y here if you want to support WMI-based hotkeys on MSI laptops.
409 To compile this driver as a module, choose M here: the module will
413 tristate "ASUS/Medion Laptop Extras (DEPRECATED)"
415 select BACKLIGHT_CLASS_DEVICE
417 This driver provides support for extra features of ACPI-compatible
418 ASUS laptops. As some of Medion laptops are made by ASUS, it may also
419 support some Medion laptops (such as 9675 for example). It makes all
420 the extra buttons generate standard ACPI events that go through
421 /proc/acpi/events, and (on some models) adds support for changing the
422 display brightness and output, switching the LCD backlight on and off,
423 and most importantly, allows you to blink those fancy LEDs intended
424 for reporting mail and wireless status.
426 Note: display switching code is currently considered EXPERIMENTAL,
427 toying with these values may even lock your machine.
429 All settings are changed via /proc/acpi/asus directory entries. Owner
430 and group for these entries can be set with asus_uid and asus_gid
433 More information and a userspace daemon for handling the extra buttons
434 at <http://acpi4asus.sf.net>.
436 If you have an ACPI-compatible ASUS laptop, say Y or M here. This
437 driver is still under development, so if your laptop is unsupported or
438 something works not quite as expected, please use the mailing list
439 available on the above page (acpi4asus-user@lists.sourceforge.net).
441 NOTE: This driver is deprecated and will probably be removed soon,
442 use asus-laptop instead.
444 config TOPSTAR_LAPTOP
445 tristate "Topstar Laptop Extras"
449 This driver adds support for hotkeys found on Topstar laptops.
451 If you have a Topstar laptop, say Y or M here.
454 tristate "Toshiba Laptop Extras"
457 depends on RFKILL || RFKILL = n
459 select BACKLIGHT_CLASS_DEVICE
461 This driver adds support for access to certain system settings
462 on "legacy free" Toshiba laptops. These laptops can be recognized by
463 their lack of a BIOS setup menu and APM support.
465 On these machines, all system configuration is handled through the
466 ACPI. This driver is required for access to controls not covered
467 by the general ACPI drivers, such as LCD brightness, video output,
470 This driver differs from the non-ACPI Toshiba laptop driver (located
471 under "Processor type and features") in several aspects.
472 Configuration is accessed by reading and writing text files in the
473 /proc tree instead of by program interface to /dev. Furthermore, no
474 power management functions are exposed, as those are handled by the
475 general ACPI drivers.
477 More information about this driver is available at
478 <http://memebeam.org/toys/ToshibaAcpiDriver>.
480 If you have a legacy free Toshiba laptop (such as the Libretto L1
483 config TOSHIBA_BT_RFKILL
484 tristate "Toshiba Bluetooth RFKill switch support"
487 This driver adds support for Bluetooth events for the RFKill
488 switch on modern Toshiba laptops with full ACPI support and
491 This driver handles RFKill events for the TOS6205 Bluetooth,
492 and re-enables it when the switch is set back to the 'on'
495 If you have a modern Toshiba laptop with a Bluetooth and an
496 RFKill switch (such as the Portege R500), say Y.
499 tristate "CMPC Laptop Extras"
500 depends on X86 && ACPI
502 select BACKLIGHT_CLASS_DEVICE
505 Support for Intel Classmate PC ACPI devices, including some
506 keys as input device, backlight device, tablet and accelerometer
