 251           This driver was formerly known as ibm-acpi.

 253           Extra functionality will be available if the rfkill (CONFIG_RFKILL)
 254           and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
 255           Note that if you want ThinkPad-ACPI to be built-in instead of
 256           modular, ALSA and rfkill will also have to be built-in.

 270
 271           If this option is enabled, ThinkPad-ACPI will export an ALSA card
 272           with a single read-only mixer control, which should be used for
 273           on-screen-display feedback purposes by the Desktop Environment.
 274

 277           documentation for details.
 278
 279           All IBM models have both volume and mute control.  Newer Lenovo

 309           Overriding LED state on ThinkPads can mask important

 312           the bay while buses are still active), etc.
 313
 314           LED control on the ThinkPad is write-only (with very few
 315           exceptions on very ancient models), which makes it
 316           impossible to know beforehand if important information will
 317           be lost when one changes LED state.
 318
 319           Users that know what they are doing can enable this option
 320           and the driver will allow control of every LED, including
 321           the ones on the dock stations.
 322
 323           Never enable this option on a distribution kernel.

 341           don't think twice: do it and say N here to save memory and avoid
 342           bad interactions with X.org.
 343
 344           NOTE: access to this feature is limited to processes with the
 345           CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
 346           where it interacts badly with X.org.

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

 358           need to do NVRAM polling to support any of the hot keys you use,
 359           unselecting this option will save about 1kB of memory.
 360
 361           ThinkPads T40 and newer, R52 and newer, and X31 and newer are
 362           unlikely to need NVRAM polling in their latest BIOS versions.
 363
 364           NVRAM polling can detect at most the following keys: ThinkPad/Access
 365           IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
 366           Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).

 419           This driver adds support for the ACPI-WMI (Windows Management
 420           Instrumentation) mapper device (PNP0C14) found on some systems.
 421
 422           ACPI-WMI is a proprietary extension to ACPI to expose parts of the
 423           ACPI firmware to userspace - this is done through various vendor
 424           defined methods and data blocks in a PNP0C14 device, which are then
 425           made available for userspace to call.
 426
 427           The implementation of this in Linux currently only exposes this to
 428           other kernel space drivers.
 429
 430           This driver is a required dependency to build the firmware specific
 431           drivers needed on many machines, including Acer and HP laptops.
 432
 433           It is safe to enable this driver even if your DSDT doesn't define
 434           any ACPI-WMI devices.

 452         ---help---
 453           This driver provides support for extra features of ACPI-compatible
 454           ASUS laptops. As some of Medion laptops are made by ASUS, it may also
 455           support some Medion laptops (such as 9675 for example).  It makes all
 456           the extra buttons generate standard ACPI events that go through
 457           /proc/acpi/events, and (on some models) adds support for changing the
 458           display brightness and output, switching the LCD backlight on and off,
 459           and most importantly, allows you to blink those fancy LEDs intended
 460           for reporting mail and wireless status.
 461
 462           Note: display switching code is currently considered EXPERIMENTAL,
 463           toying with these values may even lock your machine.
 464
 465           All settings are changed via /proc/acpi/asus directory entries. Owner
 466           and group for these entries can be set with asus_uid and asus_gid
 467           parameters.

 471
 472           If you have an ACPI-compatible ASUS laptop, say Y or M here. This
 473           driver is still under development, so if your laptop is unsupported or
 474           something works not quite as expected, please use the mailing list
 475           available on the above page (acpi4asus-user@lists.sourceforge.net).
 476
 477           NOTE: This driver is deprecated and will probably be removed soon,
 478           use asus-laptop instead.

 500           This driver adds support for access to certain system settings
 501           on "legacy free" Toshiba laptops.  These laptops can be recognized by
 502           their lack of a BIOS setup menu and APM support.
 503
 504           On these machines, all system configuration is handled through the
 505           ACPI.  This driver is required for access to controls not covered
 506           by the general ACPI drivers, such as LCD brightness, video output,
 507           etc.
 508
 509           This driver differs from the non-ACPI Toshiba laptop driver (located
 510           under "Processor type and features") in several aspects.
 511           Configuration is accessed by reading and writing text files in the
 512           /proc tree instead of by program interface to /dev.  Furthermore, no
 513           power management functions are exposed, as those are handled by the
 514           general ACPI drivers.
 515

 517           <http://memebeam.org/toys/ToshibaAcpiDriver>.

 529
 530           This driver handles RFKill events for the TOS6205 Bluetooth,
 531           and re-enables it when the switch is set back to the 'on'
 532           position.

 572
 573           The restricted access region control registers
 574           (rar_registers) are used to pass address and
 575           locking information on restricted access regions
 576           to other drivers that use restricted access regions.
 577
 578           The restricted access regions are regions of memory
 579           on the Intel MID Platform that are not accessible to
 580           the x86 processor, but are accessible to dedicated
 581           processors on board peripheral devices.
 582
 583           The purpose of the restricted access regions is to
 584           protect sensitive data from compromise by unauthorized
 585           programs running on the x86 processor.
