46 This is the new Linux driver for Asus laptops. It may also support some
47 MEDION, JVC or VICTOR laptops. It makes all the extra buttons generate
48 standard ACPI events that go through /proc/acpi/events. It also adds
49 support for video output switching, LCD backlight control, Bluetooth and
50 Wlan control, and most importantly, allows you to blink those fancy LEDs.
52 For more information and a userspace daemon for handling the extra
53 buttons see <http://acpi4asus.sf.net/>.
55 If you have an ACPI-compatible ASUS laptop, say Y or M here.
58 tristate "Dell Laptop Extras (EXPERIMENTAL)"
61 depends on EXPERIMENTAL

81 tristate "Fujitsu Laptop Extras"
84 depends on BACKLIGHT_CLASS_DEVICE
86 This is a driver for laptops built by Fujitsu:
88 * P2xxx/P5xxx/S6xxx/S7xxx series Lifebooks
89 * Possibly other Fujitsu laptop models
90 * Tested with S6410 and S7020
92 It adds support for LCD brightness control and some hotkeys.
94 If you have a Fujitsu laptop, say Y or M here.
96 config FUJITSU_LAPTOP_DEBUG
97 bool "Verbose debug mode for Fujitsu Laptop Extras"
98 depends on FUJITSU_LAPTOP
101 Enables extra debug output from the fujitsu extras driver, at the
102 expense of a slight increase in driver size.
104 If you are not sure, say N here.
107 tristate "HP Compaq TC1100 Tablet WMI Extras (EXPERIMENTAL)"
109 depends on EXPERIMENTAL
113 This is a driver for the WMI extensions (wireless and bluetooth power
114 control) of the HP Compaq TC1100 tablet.
117 tristate "HP WMI extras"
122 Say Y here if you want to support WMI-based hotkeys on HP laptops and
123 to read data from WMI such as docking or ambient light sensor state.
125 To compile this driver as a module, choose M here: the module will
129 tristate "MSI Laptop Extras"
131 depends on BACKLIGHT_CLASS_DEVICE
133 This is a driver for laptops built by MSI (MICRO-STAR
136 MSI MegaBook S270 (MS-1013)
137 Cytron/TCM/Medion/Tchibo MD96100/SAM2000
139 It adds support for Bluetooth, WLAN and LCD brightness control.
141 More information about this driver is available at
142 <http://0pointer.de/lennart/tchibo.html>.
144 If you have an MSI S270 laptop, say Y or M here.
146 config PANASONIC_LAPTOP
147 tristate "Panasonic Laptop Extras"
148 depends on INPUT && ACPI
149 depends on BACKLIGHT_CLASS_DEVICE
151 This driver adds support for access to backlight control and hotkeys
152 on Panasonic Let's Note laptops.
154 If you have a Panasonic Let's note laptop (such as the R1(N variant),
155 R2, R3, R5, T2, W2 and Y2 series), say Y.
158 tristate "Compal Laptop Extras"
160 depends on BACKLIGHT_CLASS_DEVICE
162 This is a driver for laptops built by Compal:
169 It adds support for Bluetooth, WLAN and LCD brightness control.
171 If you have an Compal FL9x/IFL9x/FT00 laptop, say Y or M here.
174 tristate "Sony Laptop Extras"
176 select BACKLIGHT_CLASS_DEVICE
180 This mini-driver drives the SNC and SPIC devices present in the ACPI
181 BIOS of the Sony Vaio laptops.
183 It gives access to some extra laptop functionalities like Bluetooth,
184 screen brightness control, Fn keys and allows powering on/off some
187 Read <file:Documentation/laptops/sony-laptop.txt> for more information.
190 bool "Sonypi compatibility"
191 depends on SONY_LAPTOP
193 Build the sonypi driver compatibility code into the sony-laptop driver.
196 tristate "ThinkPad ACPI Laptop Extras"
199 select BACKLIGHT_LCD_SUPPORT
200 select BACKLIGHT_CLASS_DEVICE
208 This is a driver for the IBM and Lenovo ThinkPad laptops. It adds
209 support for Fn-Fx key combinations, Bluetooth control, video
210 output switching, ThinkLight control, UltraBay eject and more.
211 For more information about this driver see
212 <file:Documentation/laptops/thinkpad-acpi.txt> and
213 <http://ibm-acpi.sf.net/> .
215 This driver was formerly known as ibm-acpi.
217 Extra functionality will be available if the rfkill (CONFIG_RFKILL)
218 and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
219 Note that if you want ThinkPad-ACPI to be built-in instead of
220 modular, ALSA and rfkill will also have to be built-in.
222 If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.
224 config THINKPAD_ACPI_ALSA_SUPPORT
225 bool "Console audio control ALSA interface"
226 depends on THINKPAD_ACPI
228 depends on SND = y || THINKPAD_ACPI = SND
231 Enables monitoring of the built-in console audio output control
232 (headphone and speakers), which is operated by the mute and (in
233 some ThinkPad models) volume hotkeys.
235 If this option is enabled, ThinkPad-ACPI will export an ALSA card
236 with a single read-only mixer control, which should be used for
237 on-screen-display feedback purposes by the Desktop Environment.
239 Optionally, the driver will also allow software control (the
240 ALSA mixer will be made read-write). Please refer to the driver
241 documentation for details.
243 All IBM models have both volume and mute control. Newer Lenovo
244 models only have mute control (the volume hotkeys are just normal
245 keys and volume control is done through the main HDA mixer).
247 config THINKPAD_ACPI_DEBUGFACILITIES
248 bool "Maintainer debug facilities"
249 depends on THINKPAD_ACPI
252 Enables extra stuff in the thinkpad-acpi which is completely useless
253 for normal use. Read the driver source to find out what it does.
255 Say N here, unless you were told by a kernel maintainer to do
258 config THINKPAD_ACPI_DEBUG
259 bool "Verbose debug mode"
260 depends on THINKPAD_ACPI
263 Enables extra debugging information, at the expense of a slightly
264 increase in driver size.
266 If you are not sure, say N here.
268 config THINKPAD_ACPI_UNSAFE_LEDS
269 bool "Allow control of important LEDs (unsafe)"
270 depends on THINKPAD_ACPI
273 Overriding LED state on ThinkPads can mask important
274 firmware alerts (like critical battery condition), or misled
275 the user into damaging the hardware (undocking or ejecting
276 the bay while buses are still active), etc.
278 LED control on the ThinkPad is write-only (with very few
279 exceptions on very ancient models), which makes it
280 impossible to know beforehand if important information will
281 be lost when one changes LED state.
283 Users that know what they are doing can enable this option
284 and the driver will allow control of every LED, including
285 the ones on the dock stations.
287 Never enable this option on a distribution kernel.
289 Say N here, unless you are building a kernel for your own
290 use, and need to control the important firmware LEDs.
292 config THINKPAD_ACPI_VIDEO
293 bool "Video output control support"
294 depends on THINKPAD_ACPI
297 Allows the thinkpad_acpi driver to provide an interface to control
298 the various video output ports.
300 This feature often won't work well, depending on ThinkPad model,
301 display state, video output devices in use, whether there is a X
302 server running, phase of the moon, and the current mood of
303 Schroedinger's cat. If you can use X.org's RandR to control
304 your ThinkPad's video output ports instead of this feature,
305 don't think twice: do it and say N here to save memory and avoid
306 bad interactions with X.org.
308 NOTE: access to this feature is limited to processes with the
309 CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
310 where it interacts badly with X.org.
312 If you are not sure, say Y here but do try to check if you could
313 be using X.org RandR instead.
315 config THINKPAD_ACPI_HOTKEY_POLL
316 bool "Support NVRAM polling for hot keys"
317 depends on THINKPAD_ACPI
320 Some thinkpad models benefit from NVRAM polling to detect a few of
321 the hot key press events. If you know your ThinkPad model does not
322 need to do NVRAM polling to support any of the hot keys you use,
323 unselecting this option will save about 1kB of memory.
325 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
326 unlikely to need NVRAM polling in their latest BIOS versions.
328 NVRAM polling can detect at most the following keys: ThinkPad/Access
329 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
330 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
332 If you are not sure, say Y here. The driver enables polling only if
333 it is strictly necessary to do so.
336 tristate "Thermal Management driver for Intel menlow platform"
337 depends on ACPI_THERMAL
340 ACPI thermal management enhancement driver on
341 Intel Menlow platform.
346 tristate "Eee PC Hotkey Driver (EXPERIMENTAL)"
349 depends on EXPERIMENTAL
350 select BACKLIGHT_CLASS_DEVICE
354 This driver supports the Fn-Fx keys on Eee PC laptops.
355 It also adds the ability to switch camera/wlan on/off.
357 If you have an Eee PC laptop, say Y or M here.
364 This driver adds support for the ACPI-WMI (Windows Management
365 Instrumentation) mapper device (PNP0C14) found on some systems.
367 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
368 ACPI firmware to userspace - this is done through various vendor
369 defined methods and data blocks in a PNP0C14 device, which are then
370 made available for userspace to call.
372 The implementation of this in Linux currently only exposes this to
373 other kernel space drivers.
375 This driver is a required dependency to build the firmware specific
376 drivers needed on many machines, including Acer and HP laptops.
378 It is safe to enable this driver even if your DSDT doesn't define
379 any ACPI-WMI devices.
382 tristate "ASUS/Medion Laptop Extras"
384 select BACKLIGHT_CLASS_DEVICE
386 This driver provides support for extra features of ACPI-compatible
387 ASUS laptops. As some of Medion laptops are made by ASUS, it may also
388 support some Medion laptops (such as 9675 for example). It makes all
389 the extra buttons generate standard ACPI events that go through
390 /proc/acpi/events, and (on some models) adds support for changing the
391 display brightness and output, switching the LCD backlight on and off,
392 and most importantly, allows you to blink those fancy LEDs intended
393 for reporting mail and wireless status.
395 Note: display switching code is currently considered EXPERIMENTAL,
396 toying with these values may even lock your machine.
398 All settings are changed via /proc/acpi/asus directory entries. Owner
399 and group for these entries can be set with asus_uid and asus_gid
402 More information and a userspace daemon for handling the extra buttons
403 at <http://sourceforge.net/projects/acpi4asus/>.
405 If you have an ACPI-compatible ASUS laptop, say Y or M here. This
406 driver is still under development, so if your laptop is unsupported or
407 something works not quite as expected, please use the mailing list
408 available on the above page (acpi4asus-user@lists.sourceforge.net).
410 NOTE: This driver is deprecated and will probably be removed soon,
411 use asus-laptop instead.
414 tristate "Toshiba Laptop Extras"
420 select BACKLIGHT_CLASS_DEVICE
422 This driver adds support for access to certain system settings
423 on "legacy free" Toshiba laptops. These laptops can be recognized by
424 their lack of a BIOS setup menu and APM support.
426 On these machines, all system configuration is handled through the
427 ACPI. This driver is required for access to controls not covered
428 by the general ACPI drivers, such as LCD brightness, video output,
431 This driver differs from the non-ACPI Toshiba laptop driver (located
432 under "Processor type and features") in several aspects.
433 Configuration is accessed by reading and writing text files in the
434 /proc tree instead of by program interface to /dev. Furthermore, no
435 power management functions are exposed, as those are handled by the
436 general ACPI drivers.
438 More information about this driver is available at
439 <http://memebeam.org/toys/ToshibaAcpiDriver>.
