 244           For more information about this driver see

 247
 248           This driver was formerly known as ibm-acpi.
 249
 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.

 266           some ThinkPad models) volume hotkeys.
 267
 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.
 271
 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.
 275
 276           All IBM models have both volume and mute control.  Newer Lenovo
 277           models only have mute control (the volume hotkeys are just normal

 306           Overriding LED state on ThinkPads can mask important

 308           the user into damaging the hardware (undocking or ejecting
 309           the bay while buses are still active), etc.
 310
 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.
 315
 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.
 319
 320           Never enable this option on a distribution kernel.
 321

 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.
 340
 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.

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

 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.
 357
 358           ThinkPads T40 and newer, R52 and newer, and X31 and newer are
 359           unlikely to need NVRAM polling in their latest BIOS versions.
 360
 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).

 416           This driver adds support for the ACPI-WMI (Windows Management
 417           Instrumentation) mapper device (PNP0C14) found on some systems.
 418
 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.
 423
 424           The implementation of this in Linux currently only exposes this to
 425           other kernel space drivers.
 426
 427           This driver is a required dependency to build the firmware specific
 428           drivers needed on many machines, including Acer and HP laptops.
 429
 430           It is safe to enable this driver even if your DSDT doesn't define
 431           any ACPI-WMI devices.

 449         ---help---
 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.
 458
 459           Note: display switching code is currently considered EXPERIMENTAL,
 460           toying with these values may even lock your machine.
 461
 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
 464           parameters.
 465
 466           More information and a userspace daemon for handling the extra buttons
 467           at <http://acpi4asus.sf.net>.
 468
 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).
 473
 474           NOTE: This driver is deprecated and will probably be removed soon,
 475           use asus-laptop instead.

 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.
 497
 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,
 501           etc.
 502
 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.

 522           an RFKill switch.
 523
 524           This driver handles RFKill events for the TOS6205 Bluetooth,
 525           and re-enables it when the switch is set back to the 'on'
 526           position.
 527

 566
 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.
 571
 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.
 576
 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.
