121 config FUJITSU_LAPTOP_DEBUG
122 bool "Verbose debug mode for Fujitsu Laptop Extras"
123 depends on FUJITSU_LAPTOP
126 Enables extra debug output from the fujitsu extras driver, at the
127 expense of a slight increase in driver size.
129 If you are not sure, say N here.
132 tristate "HP Compaq TC1100 Tablet WMI Extras (EXPERIMENTAL)"

175 tristate "Panasonic Laptop Extras"
176 depends on INPUT && ACPI
177 depends on BACKLIGHT_CLASS_DEVICE
178 select INPUT_SPARSEKMAP
180 This driver adds support for access to backlight control and hotkeys
181 on Panasonic Let's Note laptops.
183 If you have a Panasonic Let's note laptop (such as the R1(N variant),
184 R2, R3, R5, T2, W2 and Y2 series), say Y.
187 tristate "Compal Laptop Extras"
189 depends on BACKLIGHT_CLASS_DEVICE
192 depends on POWER_SUPPLY
194 This is a driver for laptops built by Compal:
201 It adds support for Bluetooth, WLAN and LCD brightness control.
203 If you have an Compal FL9x/IFL9x/FT00 laptop, say Y or M here.
206 tristate "Sony Laptop Extras"
208 select BACKLIGHT_CLASS_DEVICE
212 This mini-driver drives the SNC and SPIC devices present in the ACPI
213 BIOS of the Sony Vaio laptops.
215 It gives access to some extra laptop functionalities like Bluetooth,
216 screen brightness control, Fn keys and allows powering on/off some

227 config IDEAPAD_LAPTOP
228 tristate "Lenovo IdeaPad Laptop Extras"
231 select INPUT_SPARSEKMAP
233 This is a driver for the rfkill switches on Lenovo IdeaPad netbooks.
236 tristate "ThinkPad ACPI Laptop Extras"
239 depends on RFKILL || RFKILL = n
240 select BACKLIGHT_LCD_SUPPORT
241 select BACKLIGHT_CLASS_DEVICE
247 This is a driver for the IBM and Lenovo ThinkPad laptops. It adds
248 support for Fn-Fx key combinations, Bluetooth control, video
249 output switching, ThinkLight control, UltraBay eject and more.
250 For more information about this driver see
251 <file:Documentation/laptops/thinkpad-acpi.txt> and
252 <http://ibm-acpi.sf.net/> .
254 This driver was formerly known as ibm-acpi.
256 Extra functionality will be available if the rfkill (CONFIG_RFKILL)
257 and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
258 Note that if you want ThinkPad-ACPI to be built-in instead of
259 modular, ALSA and rfkill will also have to be built-in.
261 If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.
263 config THINKPAD_ACPI_ALSA_SUPPORT
264 bool "Console audio control ALSA interface"
265 depends on THINKPAD_ACPI
267 depends on SND = y || THINKPAD_ACPI = SND
270 Enables monitoring of the built-in console audio output control
271 (headphone and speakers), which is operated by the mute and (in
272 some ThinkPad models) volume hotkeys.
274 If this option is enabled, ThinkPad-ACPI will export an ALSA card
275 with a single read-only mixer control, which should be used for
276 on-screen-display feedback purposes by the Desktop Environment.
278 Optionally, the driver will also allow software control (the
279 ALSA mixer will be made read-write). Please refer to the driver
280 documentation for details.
282 All IBM models have both volume and mute control. Newer Lenovo
283 models only have mute control (the volume hotkeys are just normal
284 keys and volume control is done through the main HDA mixer).
286 config THINKPAD_ACPI_DEBUGFACILITIES
287 bool "Maintainer debug facilities"
288 depends on THINKPAD_ACPI
291 Enables extra stuff in the thinkpad-acpi which is completely useless
292 for normal use. Read the driver source to find out what it does.
294 Say N here, unless you were told by a kernel maintainer to do
297 config THINKPAD_ACPI_DEBUG
298 bool "Verbose debug mode"
299 depends on THINKPAD_ACPI
302 Enables extra debugging information, at the expense of a slightly
303 increase in driver size.
305 If you are not sure, say N here.
307 config THINKPAD_ACPI_UNSAFE_LEDS
308 bool "Allow control of important LEDs (unsafe)"
309 depends on THINKPAD_ACPI
312 Overriding LED state on ThinkPads can mask important
313 firmware alerts (like critical battery condition), or misled
314 the user into damaging the hardware (undocking or ejecting
315 the bay while buses are still active), etc.
317 LED control on the ThinkPad is write-only (with very few
318 exceptions on very ancient models), which makes it
319 impossible to know beforehand if important information will
320 be lost when one changes LED state.
322 Users that know what they are doing can enable this option
323 and the driver will allow control of every LED, including
324 the ones on the dock stations.
326 Never enable this option on a distribution kernel.
328 Say N here, unless you are building a kernel for your own
329 use, and need to control the important firmware LEDs.
331 config THINKPAD_ACPI_VIDEO
332 bool "Video output control support"
333 depends on THINKPAD_ACPI
336 Allows the thinkpad_acpi driver to provide an interface to control
337 the various video output ports.
339 This feature often won't work well, depending on ThinkPad model,
340 display state, video output devices in use, whether there is a X
341 server running, phase of the moon, and the current mood of
342 Schroedinger's cat. If you can use X.org's RandR to control
343 your ThinkPad's video output ports instead of this feature,
344 don't think twice: do it and say N here to save memory and avoid
345 bad interactions with X.org.
347 NOTE: access to this feature is limited to processes with the
348 CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
349 where it interacts badly with X.org.
351 If you are not sure, say Y here but do try to check if you could
352 be using X.org RandR instead.
354 config THINKPAD_ACPI_HOTKEY_POLL
355 bool "Support NVRAM polling for hot keys"
356 depends on THINKPAD_ACPI
359 Some thinkpad models benefit from NVRAM polling to detect a few of
360 the hot key press events. If you know your ThinkPad model does not
361 need to do NVRAM polling to support any of the hot keys you use,
362 unselecting this option will save about 1kB of memory.
364 ThinkPads T40 and newer, R52 and newer, and X31 and newer are
365 unlikely to need NVRAM polling in their latest BIOS versions.
367 NVRAM polling can detect at most the following keys: ThinkPad/Access
368 IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
369 Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
371 If you are not sure, say Y here. The driver enables polling only if
372 it is strictly necessary to do so.
375 tristate "Thinkpad Hard Drive Active Protection System (hdaps)"
376 depends on INPUT && X86
380 This driver provides support for the IBM Hard Drive Active Protection
381 System (hdaps), which provides an accelerometer and other misc. data.
382 ThinkPads starting with the R50, T41, and X40 are supported. The
383 accelerometer data is readable via sysfs.
385 This driver also provides an absolute input class device, allowing
386 the laptop to act as a pinball machine-esque joystick.
388 If your ThinkPad is not recognized by the driver, please update to latest
389 BIOS. This is especially the case for some R52 ThinkPads.
391 Say Y here if you have an applicable laptop and want to experience
392 the awesome power of hdaps.
395 tristate "Thermal Management driver for Intel menlow platform"
396 depends on ACPI_THERMAL
399 ACPI thermal management enhancement driver on
400 Intel Menlow platform.
405 tristate "Eee PC Hotkey Driver (EXPERIMENTAL)"
408 depends on EXPERIMENTAL
409 depends on RFKILL || RFKILL = n
410 depends on HOTPLUG_PCI
411 select BACKLIGHT_CLASS_DEVICE

417 This driver supports the Fn-Fx keys on Eee PC laptops.
419 It also gives access to some extra laptop functionalities like
420 Bluetooth, backlight and allows powering on/off some other

426 tristate "Eee PC WMI Hotkey Driver (EXPERIMENTAL)"
429 depends on EXPERIMENTAL
430 depends on BACKLIGHT_CLASS_DEVICE
431 depends on RFKILL || RFKILL = n
432 select INPUT_SPARSEKMAP
436 Say Y here if you want to support WMI-based hotkeys on Eee PC laptops.
438 To compile this driver as a module, choose M here: the module will
445 This driver adds support for the ACPI-WMI (Windows Management
446 Instrumentation) mapper device (PNP0C14) found on some systems.
448 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
449 ACPI firmware to userspace - this is done through various vendor
450 defined methods and data blocks in a PNP0C14 device, which are then
451 made available for userspace to call.
453 The implementation of this in Linux currently only exposes this to
454 other kernel space drivers.
456 This driver is a required dependency to build the firmware specific
457 drivers needed on many machines, including Acer and HP laptops.
459 It is safe to enable this driver even if your DSDT doesn't define
460 any ACPI-WMI devices.
463 tristate "MSI WMI extras"
466 depends on BACKLIGHT_CLASS_DEVICE
467 select INPUT_SPARSEKMAP
469 Say Y here if you want to support WMI-based hotkeys on MSI laptops.
471 To compile this driver as a module, choose M here: the module will
475 tristate "ASUS/Medion Laptop Extras (DEPRECATED)"
477 select BACKLIGHT_CLASS_DEVICE
479 This driver provides support for extra features of ACPI-compatible
480 ASUS laptops. As some of Medion laptops are made by ASUS, it may also
481 support some Medion laptops (such as 9675 for example). It makes all
482 the extra buttons generate standard ACPI events that go through
483 /proc/acpi/events, and (on some models) adds support for changing the
484 display brightness and output, switching the LCD backlight on and off,
485 and most importantly, allows you to blink those fancy LEDs intended
486 for reporting mail and wireless status.
488 Note: display switching code is currently considered EXPERIMENTAL,
489 toying with these values may even lock your machine.
491 All settings are changed via /proc/acpi/asus directory entries. Owner
492 and group for these entries can be set with asus_uid and asus_gid
495 More information and a userspace daemon for handling the extra buttons
496 at <http://acpi4asus.sf.net>.
498 If you have an ACPI-compatible ASUS laptop, say Y or M here. This
499 driver is still under development, so if your laptop is unsupported or
500 something works not quite as expected, please use the mailing list
501 available on the above page (acpi4asus-user@lists.sourceforge.net).
503 NOTE: This driver is deprecated and will probably be removed soon,
504 use asus-laptop instead.
506 config TOPSTAR_LAPTOP
507 tristate "Topstar Laptop Extras"
510 select INPUT_SPARSEKMAP
512 This driver adds support for hotkeys found on Topstar laptops.
514 If you have a Topstar laptop, say Y or M here.
517 tristate "Toshiba Laptop Extras"
521 depends on BACKLIGHT_CLASS_DEVICE
523 depends on RFKILL || RFKILL = n
525 select INPUT_SPARSEKMAP
527 This driver adds support for access to certain system settings
528 on "legacy free" Toshiba laptops. These laptops can be recognized by
529 their lack of a BIOS setup menu and APM support.
531 On these machines, all system configuration is handled through the
532 ACPI. This driver is required for access to controls not covered
533 by the general ACPI drivers, such as LCD brightness, video output,
536 This driver differs from the non-ACPI Toshiba laptop driver (located
537 under "Processor type and features") in several aspects.
538 Configuration is accessed by reading and writing text files in the
539 /proc tree instead of by program interface to /dev. Furthermore, no
540 power management functions are exposed, as those are handled by the
541 general ACPI drivers.
543 More information about this driver is available at
544 <http://memebeam.org/toys/ToshibaAcpiDriver>.
546 If you have a legacy free Toshiba laptop (such as the Libretto L1
549 config TOSHIBA_BT_RFKILL
550 tristate "Toshiba Bluetooth RFKill switch support"
553 This driver adds support for Bluetooth events for the RFKill
554 switch on modern Toshiba laptops with full ACPI support and
557 This driver handles RFKill events for the TOS6205 Bluetooth,
558 and re-enables it when the switch is set back to the 'on'
561 If you have a modern Toshiba laptop with a Bluetooth and an
562 RFKill switch (such as the Portege R500), say Y.
565 tristate "CMPC Laptop Extras"
566 depends on X86 && ACPI
567 depends on RFKILL || RFKILL=n
569 select BACKLIGHT_CLASS_DEVICE
572 Support for Intel Classmate PC ACPI devices, including some
573 keys as input device, backlight device, tablet and accelerometer

581 IPC is used to bridge the communications between kernel and SCU on
582 some embedded Intel x86 platforms. This is not needed for PC-type
585 config INTEL_SCU_IPC_UTIL
586 tristate "Intel SCU IPC utility driver"
587 depends on INTEL_SCU_IPC
590 The IPC Util driver provides an interface with the SCU enabling
591 low level access for debug work and updating the firmware. Say
592 N unless you will be doing this on an Intel MID platform.
594 config GPIO_INTEL_PMIC
595 bool "Intel PMIC GPIO support"
596 depends on INTEL_SCU_IPC && GPIOLIB
598 Say Y here to support GPIO via the SCU IPC interface
599 on Intel MID platforms.
602 bool "Restricted Access Region Register Driver"
603 depends on PCI && X86_MRST
606 This driver allows other kernel drivers access to the
607 contents of the restricted access region control registers.
609 The restricted access region control registers
610 (rar_registers) are used to pass address and
611 locking information on restricted access regions
612 to other drivers that use restricted access regions.
614 The restricted access regions are regions of memory
615 on the Intel MID Platform that are not accessible to
616 the x86 processor, but are accessible to dedicated
617 processors on board peripheral devices.
619 The purpose of the restricted access regions is to
620 protect sensitive data from compromise by unauthorized
621 programs running on the x86 processor.
624 tristate "Intel Intelligent Power Sharing"
627 Intel Calpella platforms support dynamic power sharing between the
628 CPU and GPU, maximizing performance in a given TDP. This driver,
629 along with the CPU frequency and i915 drivers, provides that
630 functionality. If in doubt, say Y here; it will only load on
634 tristate "Device driver to enable PRTL support"
635 depends on X86 && PCI
637 Enable support for IBM Premium Real Time Mode (PRTM).
638 This module will allow you the enter and exit PRTM in the BIOS via
639 sysfs on platforms that support this feature. System in PRTM will
640 not receive CPU-generated SMIs for recoverable errors. Use of this
641 feature without proper support may void your hardware warranty.
643 If the proper BIOS support is found the driver will load and create
644 /sys/devices/system/ibm_rtl/. The "state" variable will indicate
645 whether or not the BIOS is in PRTM.
646 state = 0 (BIOS SMIs on)
647 state = 1 (BIOS SMIs off)
650 tristate "OLPC XO-1 software RF kill switch"
654 Support for enabling/disabling the WLAN interface on the OLPC XO-1
