 235           For more information about this driver see

 237           <http://ibm-acpi.sf.net/> .
 238
 239           This driver was formerly known as ibm-acpi.
 240
 241           Extra functionality will be available if the rfkill (CONFIG_RFKILL)
 242           and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
 243           Note that if you want ThinkPad-ACPI to be built-in instead of
 244           modular, ALSA and rfkill will also have to be built-in.

 257           some ThinkPad models) volume hotkeys.
 258
 259           If this option is enabled, ThinkPad-ACPI will export an ALSA card
 260           with a single read-only mixer control, which should be used for
 261           on-screen-display feedback purposes by the Desktop Environment.
 262
 263           Optionally, the driver will also allow software control (the
 264           ALSA mixer will be made read-write).  Please refer to the driver
 265           documentation for details.
 266
 267           All IBM models have both volume and mute control.  Newer Lenovo
 268           models only have mute control (the volume hotkeys are just normal
 269           keys and volume control is done through the main HDA mixer).

 297           Overriding LED state on ThinkPads can mask important

 299           the user into damaging the hardware (undocking or ejecting
 300           the bay while buses are still active), etc.
 301
 302           LED control on the ThinkPad is write-only (with very few
 303           exceptions on very ancient models), which makes it
 304           impossible to know beforehand if important information will
 305           be lost when one changes LED state.
 306
 307           Users that know what they are doing can enable this option
 308           and the driver will allow control of every LED, including
 309           the ones on the dock stations.
 310
 311           Never enable this option on a distribution kernel.
 312

 325           display state, video output devices in use, whether there is a X
 326           server running, phase of the moon, and the current mood of
 327           Schroedinger's cat.  If you can use X.org's RandR to control
 328           your ThinkPad's video output ports instead of this feature,
 329           don't think twice: do it and say N here to save memory and avoid
 330           bad interactions with X.org.
 331
 332           NOTE: access to this feature is limited to processes with the
 333           CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
 334           where it interacts badly with X.org.

 344           Some thinkpad models benefit from NVRAM polling to detect a few of
 345           the hot key press events.  If you know your ThinkPad model does not
 346           need to do NVRAM polling to support any of the hot keys you use,
 347           unselecting this option will save about 1kB of memory.
 348
 349           ThinkPads T40 and newer, R52 and newer, and X31 and newer are
 350           unlikely to need NVRAM polling in their latest BIOS versions.
 351
 352           NVRAM polling can detect at most the following keys: ThinkPad/Access
 353           IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
 354           Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).

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

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

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

 513           an RFKill switch.
 514
 515           This driver handles RFKill events for the TOS6205 Bluetooth,
 516           and re-enables it when the switch is set back to the 'on'
 517           position.
 518
 519           If you have a modern Toshiba laptop with a Bluetooth and an

 548           This driver allows other kernel drivers access to the
 549           contents of the restricted access region control registers.
 550
 551           The restricted access region control registers
 552           (rar_registers) are used to pass address and
 553           locking information on restricted access regions
 554           to other drivers that use restricted access regions.
 555
 556           The restricted access regions are regions of memory
 557           on the Intel MID Platform that are not accessible to
 558           the x86 processor, but are accessible to dedicated
 559           processors on board peripheral devices.
 560
 561           The purpose of the restricted access regions is to
 562           protect sensitive data from compromise by unauthorized
 563           programs running on the x86 processor.
