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

151 tristate "MSI Laptop Extras"
153 depends on BACKLIGHT_CLASS_DEVICE
155 depends on SERIO_I8042
157 This is a driver for laptops built by MSI (MICRO-STAR
160 MSI MegaBook S270 (MS-1013)
161 Cytron/TCM/Medion/Tchibo MD96100/SAM2000
163 It adds support for Bluetooth, WLAN and LCD brightness control.
165 More information about this driver is available at
166 <http://0pointer.de/lennart/tchibo.html>.
168 If you have an MSI S270 laptop, say Y or M here.
170 config PANASONIC_LAPTOP
171 tristate "Panasonic Laptop Extras"
172 depends on INPUT && ACPI
173 depends on BACKLIGHT_CLASS_DEVICE
175 This driver adds support for access to backlight control and hotkeys
176 on Panasonic Let's Note laptops.
178 If you have a Panasonic Let's note laptop (such as the R1(N variant),
179 R2, R3, R5, T2, W2 and Y2 series), say Y.
182 tristate "Compal Laptop Extras"
184 depends on BACKLIGHT_CLASS_DEVICE
187 depends on POWER_SUPPLY
189 This is a driver for laptops built by Compal:
196 It adds support for Bluetooth, WLAN and LCD brightness control.
198 If you have an Compal FL9x/IFL9x/FT00 laptop, say Y or M here.
201 tristate "Sony Laptop Extras"
203 select BACKLIGHT_CLASS_DEVICE
207 This mini-driver drives the SNC and SPIC devices present in the ACPI
208 BIOS of the Sony Vaio laptops.
210 It gives access to some extra laptop functionalities like Bluetooth,
211 screen brightness control, Fn keys and allows powering on/off some
214 Read <file:Documentation/laptops/sony-laptop.txt> for more information.
217 bool "Sonypi compatibility"
218 depends on SONY_LAPTOP
220 Build the sonypi driver compatibility code into the sony-laptop driver.
223 tristate "Lenovo IdeaPad ACPI Laptop Extras"
227 This is a driver for the rfkill switches on Lenovo IdeaPad netbooks.
230 tristate "ThinkPad ACPI Laptop Extras"
233 depends on RFKILL || RFKILL = n
234 select BACKLIGHT_LCD_SUPPORT
235 select BACKLIGHT_CLASS_DEVICE
241 This is a driver for the IBM and Lenovo ThinkPad laptops. It adds
242 support for Fn-Fx key combinations, Bluetooth control, video
243 output switching, ThinkLight control, UltraBay eject and more.
244 For more information about this driver see
245 <file:Documentation/laptops/thinkpad-acpi.txt> and
246 <http://ibm-acpi.sf.net/> .
248 This driver was formerly known as ibm-acpi.
250 Extra functionality will be available if the rfkill (CONFIG_RFKILL)
251 and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
252 Note that if you want ThinkPad-ACPI to be built-in instead of
253 modular, ALSA and rfkill will also have to be built-in.
255 If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.
257 config THINKPAD_ACPI_ALSA_SUPPORT
258 bool "Console audio control ALSA interface"
259 depends on THINKPAD_ACPI
261 depends on SND = y || THINKPAD_ACPI = SND
264 Enables monitoring of the built-in console audio output control
265 (headphone and speakers), which is operated by the mute and (in
266 some ThinkPad models) volume hotkeys.
268 If this option is enabled, ThinkPad-ACPI will export an ALSA card
269 with a single read-only mixer control, which should be used for
270 on-screen-display feedback purposes by the Desktop Environment.
272 Optionally, the driver will also allow software control (the
273 ALSA mixer will be made read-write). Please refer to the driver
274 documentation for details.
276 All IBM models have both volume and mute control. Newer Lenovo
277 models only have mute control (the volume hotkeys are just normal
278 keys and volume control is done through the main HDA mixer).
280 config THINKPAD_ACPI_DEBUGFACILITIES
281 bool "Maintainer debug facilities"
282 depends on THINKPAD_ACPI
285 Enables extra stuff in the thinkpad-acpi which is completely useless
286 for normal use. Read the driver source to find out what it does.
288 Say N here, unless you were told by a kernel maintainer to do
291 config THINKPAD_ACPI_DEBUG
292 bool "Verbose debug mode"
293 depends on THINKPAD_ACPI
296 Enables extra debugging information, at the expense of a slightly
297 increase in driver size.
299 If you are not sure, say N here.
301 config THINKPAD_ACPI_UNSAFE_LEDS
302 bool "Allow control of important LEDs (unsafe)"
303 depends on THINKPAD_ACPI
306 Overriding LED state on ThinkPads can mask important
307 firmware alerts (like critical battery condition), or misled
308 the user into damaging the hardware (undocking or ejecting
309 the bay while buses are still active), etc.
311 LED control on the ThinkPad is write-only (with very few
312 exceptions on very ancient models), which makes it
313 impossible to know beforehand if important information will
314 be lost when one changes LED state.
316 Users that know what they are doing can enable this option
317 and the driver will allow control of every LED, including
318 the ones on the dock stations.
320 Never enable this option on a distribution kernel.
322 Say N here, unless you are building a kernel for your own
323 use, and need to control the important firmware LEDs.
325 config THINKPAD_ACPI_VIDEO
326 bool "Video output control support"
327 depends on THINKPAD_ACPI
330 Allows the thinkpad_acpi driver to provide an interface to control
331 the various video output ports.
333 This feature often won't work well, depending on ThinkPad model,
334 display state, video output devices in use, whether there is a X
335 server running, phase of the moon, and the current mood of
336 Schroedinger's cat. If you can use X.org's RandR to control
337 your ThinkPad's video output ports instead of this feature,
338 don't think twice: do it and say N here to save memory and avoid
339 bad interactions with X.org.
341 NOTE: access to this feature is limited to processes with the
342 CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
343 where it interacts badly with X.org.
345 If you are not sure, say Y here but do try to check if you could
346 be using X.org RandR instead.
348 config THINKPAD_ACPI_HOTKEY_POLL
349 bool "Support NVRAM polling for hot keys"
350 depends on THINKPAD_ACPI
353 Some thinkpad models benefit from NVRAM polling to detect a few of
354 the hot key press events. If you know your ThinkPad model does not
355 need to do NVRAM polling to support any of the hot keys you use,
356 unselecting this option will save about 1kB of memory.
358 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
359 unlikely to need NVRAM polling in their latest BIOS versions.
361 NVRAM polling can detect at most the following keys: ThinkPad/Access
362 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
363 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
365 If you are not sure, say Y here. The driver enables polling only if
366 it is strictly necessary to do so.
369 tristate "Thermal Management driver for Intel menlow platform"
370 depends on ACPI_THERMAL
373 ACPI thermal management enhancement driver on
374 Intel Menlow platform.
379 tristate "Eee PC Hotkey Driver (EXPERIMENTAL)"
382 depends on EXPERIMENTAL
383 depends on RFKILL || RFKILL = n
384 depends on HOTPLUG_PCI
385 select BACKLIGHT_CLASS_DEVICE
389 select INPUT_SPARSEKMAP
391 This driver supports the Fn-Fx keys on Eee PC laptops.
393 It also gives access to some extra laptop functionalities like
394 Bluetooth, backlight and allows powering on/off some other
397 If you have an Eee PC laptop, say Y or M here.
400 tristate "Eee PC WMI Hotkey Driver (EXPERIMENTAL)"
403 depends on EXPERIMENTAL
404 depends on BACKLIGHT_CLASS_DEVICE
405 select INPUT_SPARSEKMAP
407 Say Y here if you want to support WMI-based hotkeys on Eee PC laptops.
409 To compile this driver as a module, choose M here: the module will
416 This driver adds support for the ACPI-WMI (Windows Management
417 Instrumentation) mapper device (PNP0C14) found on some systems.
419 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
420 ACPI firmware to userspace - this is done through various vendor
421 defined methods and data blocks in a PNP0C14 device, which are then
422 made available for userspace to call.
424 The implementation of this in Linux currently only exposes this to
425 other kernel space drivers.
427 This driver is a required dependency to build the firmware specific
428 drivers needed on many machines, including Acer and HP laptops.
430 It is safe to enable this driver even if your DSDT doesn't define
431 any ACPI-WMI devices.
434 tristate "MSI WMI extras"
437 depends on BACKLIGHT_CLASS_DEVICE
438 select INPUT_SPARSEKMAP
440 Say Y here if you want to support WMI-based hotkeys on MSI laptops.
442 To compile this driver as a module, choose M here: the module will
446 tristate "ASUS/Medion Laptop Extras (DEPRECATED)"
448 select BACKLIGHT_CLASS_DEVICE
450 This driver provides support for extra features of ACPI-compatible
451 ASUS laptops. As some of Medion laptops are made by ASUS, it may also
452 support some Medion laptops (such as 9675 for example). It makes all
453 the extra buttons generate standard ACPI events that go through
454 /proc/acpi/events, and (on some models) adds support for changing the
455 display brightness and output, switching the LCD backlight on and off,
456 and most importantly, allows you to blink those fancy LEDs intended
457 for reporting mail and wireless status.
459 Note: display switching code is currently considered EXPERIMENTAL,
460 toying with these values may even lock your machine.
462 All settings are changed via /proc/acpi/asus directory entries. Owner
463 and group for these entries can be set with asus_uid and asus_gid
466 More information and a userspace daemon for handling the extra buttons
467 at <http://acpi4asus.sf.net>.
469 If you have an ACPI-compatible ASUS laptop, say Y or M here. This
470 driver is still under development, so if your laptop is unsupported or
471 something works not quite as expected, please use the mailing list
472 available on the above page (acpi4asus-user@lists.sourceforge.net).
474 NOTE: This driver is deprecated and will probably be removed soon,
475 use asus-laptop instead.
477 config TOPSTAR_LAPTOP
478 tristate "Topstar Laptop Extras"
482 This driver adds support for hotkeys found on Topstar laptops.
484 If you have a Topstar laptop, say Y or M here.
487 tristate "Toshiba Laptop Extras"
490 depends on RFKILL || RFKILL = n
492 select BACKLIGHT_CLASS_DEVICE
494 This driver adds support for access to certain system settings
495 on "legacy free" Toshiba laptops. These laptops can be recognized by
496 their lack of a BIOS setup menu and APM support.
498 On these machines, all system configuration is handled through the
499 ACPI. This driver is required for access to controls not covered
500 by the general ACPI drivers, such as LCD brightness, video output,
503 This driver differs from the non-ACPI Toshiba laptop driver (located
504 under "Processor type and features") in several aspects.
505 Configuration is accessed by reading and writing text files in the
506 /proc tree instead of by program interface to /dev. Furthermore, no
507 power management functions are exposed, as those are handled by the
508 general ACPI drivers.
510 More information about this driver is available at
511 <http://memebeam.org/toys/ToshibaAcpiDriver>.
513 If you have a legacy free Toshiba laptop (such as the Libretto L1
516 config TOSHIBA_BT_RFKILL
517 tristate "Toshiba Bluetooth RFKill switch support"
520 This driver adds support for Bluetooth events for the RFKill
521 switch on modern Toshiba laptops with full ACPI support and
524 This driver handles RFKill events for the TOS6205 Bluetooth,
525 and re-enables it when the switch is set back to the 'on'
528 If you have a modern Toshiba laptop with a Bluetooth and an
529 RFKill switch (such as the Portege R500), say Y.
532 tristate "CMPC Laptop Extras"
533 depends on X86 && ACPI
534 depends on RFKILL || RFKILL=n
536 select BACKLIGHT_CLASS_DEVICE
539 Support for Intel Classmate PC ACPI devices, including some
540 keys as input device, backlight device, tablet and accelerometer
544 bool "Intel SCU IPC Support"
548 IPC is used to bridge the communications between kernel and SCU on
549 some embedded Intel x86 platforms. This is not needed for PC-type
552 config GPIO_INTEL_PMIC
553 bool "Intel PMIC GPIO support"
554 depends on INTEL_SCU_IPC && GPIOLIB
556 Say Y here to support GPIO via the SCU IPC interface
557 on Intel MID platforms.
560 bool "Restricted Access Region Register Driver"
561 depends on PCI && X86_MRST
564 This driver allows other kernel drivers access to the
565 contents of the restricted access region control registers.
567 The restricted access region control registers
568 (rar_registers) are used to pass address and
569 locking information on restricted access regions
570 to other drivers that use restricted access regions.
572 The restricted access regions are regions of memory
573 on the Intel MID Platform that are not accessible to
574 the x86 processor, but are accessible to dedicated
575 processors on board peripheral devices.
577 The purpose of the restricted access regions is to
578 protect sensitive data from compromise by unauthorized
579 programs running on the x86 processor.
582 tristate "Intel Intelligent Power Sharing"
585 Intel Calpella platforms support dynamic power sharing between the
586 CPU and GPU, maximizing performance in a given TDP. This driver,
587 along with the CPU frequency and i915 drivers, provides that
588 functionality. If in doubt, say Y here; it will only load on
