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"

150 tristate "MSI Laptop Extras"
152 depends on BACKLIGHT_CLASS_DEVICE
154 depends on SERIO_I8042
156 This is a driver for laptops built by MSI (MICRO-STAR
159 MSI MegaBook S270 (MS-1013)
160 Cytron/TCM/Medion/Tchibo MD96100/SAM2000
162 It adds support for Bluetooth, WLAN and LCD brightness control.
164 More information about this driver is available at
165 <http://0pointer.de/lennart/tchibo.html>.
167 If you have an MSI S270 laptop, say Y or M here.
169 config PANASONIC_LAPTOP
170 tristate "Panasonic Laptop Extras"
171 depends on INPUT && ACPI
172 depends on BACKLIGHT_CLASS_DEVICE
174 This driver adds support for access to backlight control and hotkeys
175 on Panasonic Let's Note laptops.
177 If you have a Panasonic Let's note laptop (such as the R1(N variant),
178 R2, R3, R5, T2, W2 and Y2 series), say Y.
181 tristate "Compal Laptop Extras"
183 depends on BACKLIGHT_CLASS_DEVICE
186 This is a driver for laptops built by Compal:
193 It adds support for Bluetooth, WLAN and LCD brightness control.
195 If you have an Compal FL9x/IFL9x/FT00 laptop, say Y or M here.
198 tristate "Sony Laptop Extras"
200 select BACKLIGHT_CLASS_DEVICE
204 This mini-driver drives the SNC and SPIC devices present in the ACPI
205 BIOS of the Sony Vaio laptops.
207 It gives access to some extra laptop functionalities like Bluetooth,
208 screen brightness control, Fn keys and allows powering on/off some
211 Read <file:Documentation/laptops/sony-laptop.txt> for more information.
214 bool "Sonypi compatibility"
215 depends on SONY_LAPTOP
217 Build the sonypi driver compatibility code into the sony-laptop driver.
220 tristate "ThinkPad ACPI Laptop Extras"
223 depends on RFKILL || RFKILL = n
224 select BACKLIGHT_LCD_SUPPORT
225 select BACKLIGHT_CLASS_DEVICE
231 This is a driver for the IBM and Lenovo ThinkPad laptops. It adds
232 support for Fn-Fx key combinations, Bluetooth control, video
233 output switching, ThinkLight control, UltraBay eject and more.
234 For more information about this driver see
235 <file:Documentation/laptops/thinkpad-acpi.txt> and
236 <http://ibm-acpi.sf.net/> .
238 This driver was formerly known as ibm-acpi.
240 Extra functionality will be available if the rfkill (CONFIG_RFKILL)
241 and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
242 Note that if you want ThinkPad-ACPI to be built-in instead of
243 modular, ALSA and rfkill will also have to be built-in.
245 If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.
247 config THINKPAD_ACPI_ALSA_SUPPORT
248 bool "Console audio control ALSA interface"
249 depends on THINKPAD_ACPI
251 depends on SND = y || THINKPAD_ACPI = SND
254 Enables monitoring of the built-in console audio output control
255 (headphone and speakers), which is operated by the mute and (in
256 some ThinkPad models) volume hotkeys.
258 If this option is enabled, ThinkPad-ACPI will export an ALSA card
259 with a single read-only mixer control, which should be used for
260 on-screen-display feedback purposes by the Desktop Environment.
262 Optionally, the driver will also allow software control (the
263 ALSA mixer will be made read-write). Please refer to the driver
264 documentation for details.
266 All IBM models have both volume and mute control. Newer Lenovo
267 models only have mute control (the volume hotkeys are just normal
268 keys and volume control is done through the main HDA mixer).
270 config THINKPAD_ACPI_DEBUGFACILITIES
271 bool "Maintainer debug facilities"
272 depends on THINKPAD_ACPI
275 Enables extra stuff in the thinkpad-acpi which is completely useless
276 for normal use. Read the driver source to find out what it does.
278 Say N here, unless you were told by a kernel maintainer to do
281 config THINKPAD_ACPI_DEBUG
282 bool "Verbose debug mode"
283 depends on THINKPAD_ACPI
286 Enables extra debugging information, at the expense of a slightly
287 increase in driver size.
289 If you are not sure, say N here.
291 config THINKPAD_ACPI_UNSAFE_LEDS
292 bool "Allow control of important LEDs (unsafe)"
293 depends on THINKPAD_ACPI
296 Overriding LED state on ThinkPads can mask important
297 firmware alerts (like critical battery condition), or misled
298 the user into damaging the hardware (undocking or ejecting
299 the bay while buses are still active), etc.
301 LED control on the ThinkPad is write-only (with very few
302 exceptions on very ancient models), which makes it
303 impossible to know beforehand if important information will
304 be lost when one changes LED state.
306 Users that know what they are doing can enable this option
307 and the driver will allow control of every LED, including
308 the ones on the dock stations.
310 Never enable this option on a distribution kernel.
312 Say N here, unless you are building a kernel for your own
313 use, and need to control the important firmware LEDs.
315 config THINKPAD_ACPI_VIDEO
316 bool "Video output control support"
317 depends on THINKPAD_ACPI
320 Allows the thinkpad_acpi driver to provide an interface to control
321 the various video output ports.
323 This feature often won't work well, depending on ThinkPad model,
324 display state, video output devices in use, whether there is a X
325 server running, phase of the moon, and the current mood of
326 Schroedinger's cat. If you can use X.org's RandR to control
327 your ThinkPad's video output ports instead of this feature,
328 don't think twice: do it and say N here to save memory and avoid
329 bad interactions with X.org.
331 NOTE: access to this feature is limited to processes with the
332 CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
333 where it interacts badly with X.org.
335 If you are not sure, say Y here but do try to check if you could
336 be using X.org RandR instead.
338 config THINKPAD_ACPI_HOTKEY_POLL
339 bool "Support NVRAM polling for hot keys"
340 depends on THINKPAD_ACPI
343 Some thinkpad models benefit from NVRAM polling to detect a few of
344 the hot key press events. If you know your ThinkPad model does not
345 need to do NVRAM polling to support any of the hot keys you use,
346 unselecting this option will save about 1kB of memory.
348 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
349 unlikely to need NVRAM polling in their latest BIOS versions.
351 NVRAM polling can detect at most the following keys: ThinkPad/Access
352 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
353 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
355 If you are not sure, say Y here. The driver enables polling only if
356 it is strictly necessary to do so.
359 tristate "Thermal Management driver for Intel menlow platform"
360 depends on ACPI_THERMAL
363 ACPI thermal management enhancement driver on
364 Intel Menlow platform.
369 tristate "Eee PC Hotkey Driver (EXPERIMENTAL)"
372 depends on EXPERIMENTAL
373 depends on RFKILL || RFKILL = n
374 depends on HOTPLUG_PCI
375 select BACKLIGHT_CLASS_DEVICE
379 select INPUT_SPARSEKMAP
381 This driver supports the Fn-Fx keys on Eee PC laptops.
383 It also gives access to some extra laptop functionalities like
384 Bluetooth, backlight and allows powering on/off some other
387 If you have an Eee PC laptop, say Y or M here.
390 tristate "Eee PC WMI Hotkey Driver (EXPERIMENTAL)"
393 depends on EXPERIMENTAL
394 depends on BACKLIGHT_CLASS_DEVICE
395 select INPUT_SPARSEKMAP
397 Say Y here if you want to support WMI-based hotkeys on Eee PC laptops.
399 To compile this driver as a module, choose M here: the module will
406 This driver adds support for the ACPI-WMI (Windows Management
407 Instrumentation) mapper device (PNP0C14) found on some systems.
409 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
410 ACPI firmware to userspace - this is done through various vendor
411 defined methods and data blocks in a PNP0C14 device, which are then
412 made available for userspace to call.
414 The implementation of this in Linux currently only exposes this to
415 other kernel space drivers.
417 This driver is a required dependency to build the firmware specific
418 drivers needed on many machines, including Acer and HP laptops.
420 It is safe to enable this driver even if your DSDT doesn't define
421 any ACPI-WMI devices.
424 tristate "MSI WMI extras"
427 depends on BACKLIGHT_CLASS_DEVICE
428 select INPUT_SPARSEKMAP
430 Say Y here if you want to support WMI-based hotkeys on MSI laptops.
432 To compile this driver as a module, choose M here: the module will
436 tristate "ASUS/Medion Laptop Extras (DEPRECATED)"
438 select BACKLIGHT_CLASS_DEVICE
440 This driver provides support for extra features of ACPI-compatible
441 ASUS laptops. As some of Medion laptops are made by ASUS, it may also
442 support some Medion laptops (such as 9675 for example). It makes all
443 the extra buttons generate standard ACPI events that go through
444 /proc/acpi/events, and (on some models) adds support for changing the
445 display brightness and output, switching the LCD backlight on and off,
446 and most importantly, allows you to blink those fancy LEDs intended
447 for reporting mail and wireless status.
449 Note: display switching code is currently considered EXPERIMENTAL,
450 toying with these values may even lock your machine.
452 All settings are changed via /proc/acpi/asus directory entries. Owner
453 and group for these entries can be set with asus_uid and asus_gid
456 More information and a userspace daemon for handling the extra buttons
457 at <http://acpi4asus.sf.net>.
459 If you have an ACPI-compatible ASUS laptop, say Y or M here. This
460 driver is still under development, so if your laptop is unsupported or
461 something works not quite as expected, please use the mailing list
462 available on the above page (acpi4asus-user@lists.sourceforge.net).
464 NOTE: This driver is deprecated and will probably be removed soon,
465 use asus-laptop instead.
467 config TOPSTAR_LAPTOP
468 tristate "Topstar Laptop Extras"
472 This driver adds support for hotkeys found on Topstar laptops.
474 If you have a Topstar laptop, say Y or M here.
477 tristate "Toshiba Laptop Extras"
480 depends on RFKILL || RFKILL = n
482 select BACKLIGHT_CLASS_DEVICE
484 This driver adds support for access to certain system settings
485 on "legacy free" Toshiba laptops. These laptops can be recognized by
486 their lack of a BIOS setup menu and APM support.
488 On these machines, all system configuration is handled through the
489 ACPI. This driver is required for access to controls not covered
490 by the general ACPI drivers, such as LCD brightness, video output,
493 This driver differs from the non-ACPI Toshiba laptop driver (located
494 under "Processor type and features") in several aspects.
495 Configuration is accessed by reading and writing text files in the
496 /proc tree instead of by program interface to /dev. Furthermore, no
497 power management functions are exposed, as those are handled by the
498 general ACPI drivers.
500 More information about this driver is available at
501 <http://memebeam.org/toys/ToshibaAcpiDriver>.
503 If you have a legacy free Toshiba laptop (such as the Libretto L1
506 config TOSHIBA_BT_RFKILL
507 tristate "Toshiba Bluetooth RFKill switch support"
510 This driver adds support for Bluetooth events for the RFKill
511 switch on modern Toshiba laptops with full ACPI support and
514 This driver handles RFKill events for the TOS6205 Bluetooth,
515 and re-enables it when the switch is set back to the 'on'
518 If you have a modern Toshiba laptop with a Bluetooth and an
519 RFKill switch (such as the Portege R500), say Y.
522 tristate "CMPC Laptop Extras"
523 depends on X86 && ACPI
524 depends on RFKILL || RFKILL=n
526 select BACKLIGHT_CLASS_DEVICE
529 Support for Intel Classmate PC ACPI devices, including some
530 keys as input device, backlight device, tablet and accelerometer
534 bool "Intel SCU IPC Support"
538 IPC is used to bridge the communications between kernel and SCU on
539 some embedded Intel x86 platforms. This is not needed for PC-type
543 tristate "Intel Intelligent Power Sharing"
546 Intel Calpella platforms support dynamic power sharing between the
547 CPU and GPU, maximizing performance in a given TDP. This driver,
548 along with the CPU frequency and i915 drivers, provides that
549 functionality. If in doubt, say Y here; it will only load on
