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.
75 tristate "Dell Laptop Extras (EXPERIMENTAL)"

98 tristate "Fujitsu Laptop Extras"
101 depends on BACKLIGHT_CLASS_DEVICE
102 depends on LEDS_CLASS || LEDS_CLASS=n
104 This is a driver for laptops built by Fujitsu:
106 * P2xxx/P5xxx/S6xxx/S7xxx series Lifebooks
107 * Possibly other Fujitsu laptop models
108 * Tested with S6410 and S7020
110 It adds support for LCD brightness control and some hotkeys.
112 If you have a Fujitsu laptop, say Y or M here.
114 config FUJITSU_LAPTOP_DEBUG
115 bool "Verbose debug mode for Fujitsu Laptop Extras"
116 depends on FUJITSU_LAPTOP
119 Enables extra debug output from the fujitsu extras driver, at the
120 expense of a slight increase in driver size.
122 If you are not sure, say N here.
125 tristate "HP Compaq TC1100 Tablet WMI Extras (EXPERIMENTAL)"
127 depends on EXPERIMENTAL
131 This is a driver for the WMI extensions (wireless and bluetooth power
132 control) of the HP Compaq TC1100 tablet.
135 tristate "HP WMI extras"
138 depends on RFKILL || RFKILL = n

141 to read data from WMI such as docking or ambient light sensor state.
143 To compile this driver as a module, choose M here: the module will
147 tristate "MSI Laptop Extras"
149 depends on BACKLIGHT_CLASS_DEVICE
151 This is a driver for laptops built by MSI (MICRO-STAR
154 MSI MegaBook S270 (MS-1013)
155 Cytron/TCM/Medion/Tchibo MD96100/SAM2000
157 It adds support for Bluetooth, WLAN and LCD brightness control.
159 More information about this driver is available at
160 <http://0pointer.de/lennart/tchibo.html>.
162 If you have an MSI S270 laptop, say Y or M here.
164 config PANASONIC_LAPTOP
165 tristate "Panasonic Laptop Extras"
166 depends on INPUT && ACPI
167 depends on BACKLIGHT_CLASS_DEVICE
169 This driver adds support for access to backlight control and hotkeys
170 on Panasonic Let's Note laptops.
172 If you have a Panasonic Let's note laptop (such as the R1(N variant),
173 R2, R3, R5, T2, W2 and Y2 series), say Y.
176 tristate "Compal Laptop Extras"
178 depends on BACKLIGHT_CLASS_DEVICE
180 This is a driver for laptops built by Compal:
187 It adds support for Bluetooth, WLAN and LCD brightness control.
189 If you have an Compal FL9x/IFL9x/FT00 laptop, say Y or M here.
192 tristate "Sony Laptop Extras"
194 select BACKLIGHT_CLASS_DEVICE
198 This mini-driver drives the SNC and SPIC devices present in the ACPI
199 BIOS of the Sony Vaio laptops.
201 It gives access to some extra laptop functionalities like Bluetooth,
202 screen brightness control, Fn keys and allows powering on/off some
205 Read <file:Documentation/laptops/sony-laptop.txt> for more information.
208 bool "Sonypi compatibility"
209 depends on SONY_LAPTOP
211 Build the sonypi driver compatibility code into the sony-laptop driver.
214 tristate "ThinkPad ACPI Laptop Extras"
217 depends on RFKILL || RFKILL = n
218 select BACKLIGHT_LCD_SUPPORT
219 select BACKLIGHT_CLASS_DEVICE
225 This is a driver for the IBM and Lenovo ThinkPad laptops. It adds
226 support for Fn-Fx key combinations, Bluetooth control, video
227 output switching, ThinkLight control, UltraBay eject and more.
228 For more information about this driver see
229 <file:Documentation/laptops/thinkpad-acpi.txt> and
230 <http://ibm-acpi.sf.net/> .
232 This driver was formerly known as ibm-acpi.
234 Extra functionality will be available if the rfkill (CONFIG_RFKILL)
235 and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
236 Note that if you want ThinkPad-ACPI to be built-in instead of
237 modular, ALSA and rfkill will also have to be built-in.
239 If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.
241 config THINKPAD_ACPI_ALSA_SUPPORT
242 bool "Console audio control ALSA interface"
243 depends on THINKPAD_ACPI
245 depends on SND = y || THINKPAD_ACPI = SND
248 Enables monitoring of the built-in console audio output control
249 (headphone and speakers), which is operated by the mute and (in
250 some ThinkPad models) volume hotkeys.
252 If this option is enabled, ThinkPad-ACPI will export an ALSA card
253 with a single read-only mixer control, which should be used for
254 on-screen-display feedback purposes by the Desktop Environment.
256 Optionally, the driver will also allow software control (the
257 ALSA mixer will be made read-write). Please refer to the driver
258 documentation for details.
260 All IBM models have both volume and mute control. Newer Lenovo
261 models only have mute control (the volume hotkeys are just normal
262 keys and volume control is done through the main HDA mixer).
264 config THINKPAD_ACPI_DEBUGFACILITIES
265 bool "Maintainer debug facilities"
266 depends on THINKPAD_ACPI
269 Enables extra stuff in the thinkpad-acpi which is completely useless
270 for normal use. Read the driver source to find out what it does.
272 Say N here, unless you were told by a kernel maintainer to do
275 config THINKPAD_ACPI_DEBUG
276 bool "Verbose debug mode"
277 depends on THINKPAD_ACPI
280 Enables extra debugging information, at the expense of a slightly
281 increase in driver size.
283 If you are not sure, say N here.
285 config THINKPAD_ACPI_UNSAFE_LEDS
286 bool "Allow control of important LEDs (unsafe)"
287 depends on THINKPAD_ACPI
290 Overriding LED state on ThinkPads can mask important
291 firmware alerts (like critical battery condition), or misled
292 the user into damaging the hardware (undocking or ejecting
293 the bay while buses are still active), etc.
295 LED control on the ThinkPad is write-only (with very few
296 exceptions on very ancient models), which makes it
297 impossible to know beforehand if important information will
298 be lost when one changes LED state.
300 Users that know what they are doing can enable this option
301 and the driver will allow control of every LED, including
302 the ones on the dock stations.
304 Never enable this option on a distribution kernel.
306 Say N here, unless you are building a kernel for your own
307 use, and need to control the important firmware LEDs.
309 config THINKPAD_ACPI_VIDEO
310 bool "Video output control support"
311 depends on THINKPAD_ACPI
314 Allows the thinkpad_acpi driver to provide an interface to control
315 the various video output ports.
317 This feature often won't work well, depending on ThinkPad model,
318 display state, video output devices in use, whether there is a X
319 server running, phase of the moon, and the current mood of
320 Schroedinger's cat. If you can use X.org's RandR to control
321 your ThinkPad's video output ports instead of this feature,
322 don't think twice: do it and say N here to save memory and avoid
323 bad interactions with X.org.
325 NOTE: access to this feature is limited to processes with the
326 CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
327 where it interacts badly with X.org.
329 If you are not sure, say Y here but do try to check if you could
330 be using X.org RandR instead.
332 config THINKPAD_ACPI_HOTKEY_POLL
333 bool "Support NVRAM polling for hot keys"
334 depends on THINKPAD_ACPI
337 Some thinkpad models benefit from NVRAM polling to detect a few of
338 the hot key press events. If you know your ThinkPad model does not
339 need to do NVRAM polling to support any of the hot keys you use,
340 unselecting this option will save about 1kB of memory.
342 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
343 unlikely to need NVRAM polling in their latest BIOS versions.
345 NVRAM polling can detect at most the following keys: ThinkPad/Access
346 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
347 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
349 If you are not sure, say Y here. The driver enables polling only if
350 it is strictly necessary to do so.
353 tristate "Thermal Management driver for Intel menlow platform"
354 depends on ACPI_THERMAL
357 ACPI thermal management enhancement driver on
358 Intel Menlow platform.
363 tristate "Eee PC Hotkey Driver (EXPERIMENTAL)"
366 depends on EXPERIMENTAL
367 depends on RFKILL || RFKILL = n
368 depends on HOTPLUG_PCI
369 select BACKLIGHT_CLASS_DEVICE
372 This driver supports the Fn-Fx keys on Eee PC laptops.
374 It also gives access to some extra laptop functionalities like
375 Bluetooth, backlight and allows powering on/off some other
378 If you have an Eee PC laptop, say Y or M here.
385 This driver adds support for the ACPI-WMI (Windows Management
386 Instrumentation) mapper device (PNP0C14) found on some systems.
388 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
389 ACPI firmware to userspace - this is done through various vendor
390 defined methods and data blocks in a PNP0C14 device, which are then
391 made available for userspace to call.
393 The implementation of this in Linux currently only exposes this to
394 other kernel space drivers.
396 This driver is a required dependency to build the firmware specific
397 drivers needed on many machines, including Acer and HP laptops.
399 It is safe to enable this driver even if your DSDT doesn't define
400 any ACPI-WMI devices.
403 tristate "ASUS/Medion Laptop Extras (DEPRECATED)"
405 select BACKLIGHT_CLASS_DEVICE
407 This driver provides support for extra features of ACPI-compatible
408 ASUS laptops. As some of Medion laptops are made by ASUS, it may also
409 support some Medion laptops (such as 9675 for example). It makes all
410 the extra buttons generate standard ACPI events that go through
411 /proc/acpi/events, and (on some models) adds support for changing the
412 display brightness and output, switching the LCD backlight on and off,
413 and most importantly, allows you to blink those fancy LEDs intended
414 for reporting mail and wireless status.
416 Note: display switching code is currently considered EXPERIMENTAL,
417 toying with these values may even lock your machine.
419 All settings are changed via /proc/acpi/asus directory entries. Owner
420 and group for these entries can be set with asus_uid and asus_gid
423 More information and a userspace daemon for handling the extra buttons
424 at <http://acpi4asus.sf.net>.
426 If you have an ACPI-compatible ASUS laptop, say Y or M here. This
427 driver is still under development, so if your laptop is unsupported or
428 something works not quite as expected, please use the mailing list
429 available on the above page (acpi4asus-user@lists.sourceforge.net).
431 NOTE: This driver is deprecated and will probably be removed soon,
432 use asus-laptop instead.
434 config TOPSTAR_LAPTOP
435 tristate "Topstar Laptop Extras"
439 This driver adds support for hotkeys found on Topstar laptops.
441 If you have a Topstar laptop, say Y or M here.
444 tristate "Toshiba Laptop Extras"
447 depends on RFKILL || RFKILL = n
449 select BACKLIGHT_CLASS_DEVICE
451 This driver adds support for access to certain system settings
452 on "legacy free" Toshiba laptops. These laptops can be recognized by
453 their lack of a BIOS setup menu and APM support.
455 On these machines, all system configuration is handled through the
456 ACPI. This driver is required for access to controls not covered
457 by the general ACPI drivers, such as LCD brightness, video output,
460 This driver differs from the non-ACPI Toshiba laptop driver (located
461 under "Processor type and features") in several aspects.
462 Configuration is accessed by reading and writing text files in the
463 /proc tree instead of by program interface to /dev. Furthermore, no
464 power management functions are exposed, as those are handled by the
465 general ACPI drivers.
467 More information about this driver is available at
468 <http://memebeam.org/toys/ToshibaAcpiDriver>.
