 237           For more information about this driver see

 240
 241           This driver was formerly known as ibm-acpi.
 242
 243           Extra functionality will be available if the rfkill (CONFIG_RFKILL)
 244           and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
 245           Note that if you want ThinkPad-ACPI to be built-in instead of
 246           modular, ALSA and rfkill will also have to be built-in.

 260
 261           If this option is enabled, ThinkPad-ACPI will export an ALSA card
 262           with a single read-only mixer control, which should be used for
 263           on-screen-display feedback purposes by the Desktop Environment.
 264
 265           Optionally, the driver will also allow software control (the
 266           ALSA mixer will be made read-write).  Please refer to the driver
 267           documentation for details.
 268
 269           All IBM models have both volume and mute control.  Newer Lenovo
 270           models only have mute control (the volume hotkeys are just normal
 271           keys and volume control is done through the main HDA mixer).

 299           Overriding LED state on ThinkPads can mask important

 302           the bay while buses are still active), etc.
 303
 304           LED control on the ThinkPad is write-only (with very few
 305           exceptions on very ancient models), which makes it
 306           impossible to know beforehand if important information will
 307           be lost when one changes LED state.
 308
 309           Users that know what they are doing can enable this option
 310           and the driver will allow control of every LED, including
 311           the ones on the dock stations.
 312
 313           Never enable this option on a distribution kernel.
 314

 329           Schroedinger's cat.  If you can use X.org's RandR to control
 330           your ThinkPad's video output ports instead of this feature,
 331           don't think twice: do it and say N here to save memory and avoid
 332           bad interactions with X.org.
 333
 334           NOTE: access to this feature is limited to processes with the
 335           CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
 336           where it interacts badly with X.org.

 346           Some thinkpad models benefit from NVRAM polling to detect a few of

 348           need to do NVRAM polling to support any of the hot keys you use,
 349           unselecting this option will save about 1kB of memory.
 350
 351           ThinkPads T40 and newer, R52 and newer, and X31 and newer are
 352           unlikely to need NVRAM polling in their latest BIOS versions.
 353
 354           NVRAM polling can detect at most the following keys: ThinkPad/Access
 355           IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
 356           Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).

 408         help
 409           This driver adds support for the ACPI-WMI (Windows Management
 410           Instrumentation) mapper device (PNP0C14) found on some systems.
 411
 412           ACPI-WMI is a proprietary extension to ACPI to expose parts of the
 413           ACPI firmware to userspace - this is done through various vendor
 414           defined methods and data blocks in a PNP0C14 device, which are then
 415           made available for userspace to call.
 416
 417           The implementation of this in Linux currently only exposes this to
 418           other kernel space drivers.
 419
 420           This driver is a required dependency to build the firmware specific
 421           drivers needed on many machines, including Acer and HP laptops.
 422
 423           It is safe to enable this driver even if your DSDT doesn't define
 424           any ACPI-WMI devices.

 436          be called msi-wmi.

 442         ---help---
 443           This driver provides support for extra features of ACPI-compatible
 444           ASUS laptops. As some of Medion laptops are made by ASUS, it may also
 445           support some Medion laptops (such as 9675 for example).  It makes all
 446           the extra buttons generate standard ACPI events that go through
 447           /proc/acpi/events, and (on some models) adds support for changing the
 448           display brightness and output, switching the LCD backlight on and off,
 449           and most importantly, allows you to blink those fancy LEDs intended
 450           for reporting mail and wireless status.
 451
 452           Note: display switching code is currently considered EXPERIMENTAL,
 453           toying with these values may even lock your machine.
 454
 455           All settings are changed via /proc/acpi/asus directory entries. Owner
 456           and group for these entries can be set with asus_uid and asus_gid
 457           parameters.
 458
 459           More information and a userspace daemon for handling the extra buttons
 460           at <http://acpi4asus.sf.net>.
 461
 462           If you have an ACPI-compatible ASUS laptop, say Y or M here. This
 463           driver is still under development, so if your laptop is unsupported or
 464           something works not quite as expected, please use the mailing list
 465           available on the above page (acpi4asus-user@lists.sourceforge.net).
 466
 467           NOTE: This driver is deprecated and will probably be removed soon,
 468           use asus-laptop instead.

 486         ---help---
 487           This driver adds support for access to certain system settings
 488           on "legacy free" Toshiba laptops.  These laptops can be recognized by
 489           their lack of a BIOS setup menu and APM support.
 490
 491           On these machines, all system configuration is handled through the
 492           ACPI.  This driver is required for access to controls not covered
 493           by the general ACPI drivers, such as LCD brightness, video output,
 494           etc.
 495
 496           This driver differs from the non-ACPI Toshiba laptop driver (located
 497           under "Processor type and features") in several aspects.
 498           Configuration is accessed by reading and writing text files in the
 499           /proc tree instead of by program interface to /dev.  Furthermore, no
 500           power management functions are exposed, as those are handled by the
 501           general ACPI drivers.
 502
 503           More information about this driver is available at
 504           <http://memebeam.org/toys/ToshibaAcpiDriver>.

 513           This driver adds support for Bluetooth events for the RFKill
 514           switch on modern Toshiba laptops with full ACPI support and
 515           an RFKill switch.
 516
 517           This driver handles RFKill events for the TOS6205 Bluetooth,
 518           and re-enables it when the switch is set back to the 'on'
 519           position.
 520
 521           If you have a modern Toshiba laptop with a Bluetooth and an
 522           RFKill switch (such as the Portege R500), say Y.

 557           This driver allows other kernel drivers access to the
 558           contents of the restricted access region control registers.
 559
 560           The restricted access region control registers
 561           (rar_registers) are used to pass address and
 562           locking information on restricted access regions
 563           to other drivers that use restricted access regions.
 564
 565           The restricted access regions are regions of memory
 566           on the Intel MID Platform that are not accessible to
 567           the x86 processor, but are accessible to dedicated
 568           processors on board peripheral devices.
 569
 570           The purpose of the restricted access regions is to
 571           protect sensitive data from compromise by unauthorized
 572           programs running on the x86 processor.
