 281           For more information about this driver see
 282           <file:Documentation/laptops/thinkpad-acpi.txt> and
 283           <http://ibm-acpi.sf.net/> .
 284
 285           This driver was formerly known as ibm-acpi.
 286
 287           Extra functionality will be available if the rfkill (CONFIG_RFKILL)
 288           and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
 289           Note that if you want ThinkPad-ACPI to be built-in instead of
 290           modular, ALSA and rfkill will also have to be built-in.

 304
 305           If this option is enabled, ThinkPad-ACPI will export an ALSA card
 306           with a single read-only mixer control, which should be used for
 307           on-screen-display feedback purposes by the Desktop Environment.
 308
 309           Optionally, the driver will also allow software control (the
 310           ALSA mixer will be made read-write).  Please refer to the driver
 311           documentation for details.
 312
 313           All IBM models have both volume and mute control.  Newer Lenovo
 314           models only have mute control (the volume hotkeys are just normal

 343           Overriding LED state on ThinkPads can mask important

 345           the user into damaging the hardware (undocking or ejecting
 346           the bay while buses are still active), etc.
 347
 348           LED control on the ThinkPad is write-only (with very few
 349           exceptions on very ancient models), which makes it
 350           impossible to know beforehand if important information will
 351           be lost when one changes LED state.
 352
 353           Users that know what they are doing can enable this option
 354           and the driver will allow control of every LED, including
 355           the ones on the dock stations.
 356
 357           Never enable this option on a distribution kernel.
 358
 359           Say N here, unless you are building a kernel for your own

 369
 370           This feature often won't work well, depending on ThinkPad model,
 371           display state, video output devices in use, whether there is a X
 372           server running, phase of the moon, and the current mood of
 373           Schroedinger's cat.  If you can use X.org's RandR to control
 374           your ThinkPad's video output ports instead of this feature,
 375           don't think twice: do it and say N here to save memory and avoid
 376           bad interactions with X.org.
 377
 378           NOTE: access to this feature is limited to processes with the
 379           CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
 380           where it interacts badly with X.org.
 381

 389         ---help---
 390           Some thinkpad models benefit from NVRAM polling to detect a few of
 391           the hot key press events.  If you know your ThinkPad model does not
 392           need to do NVRAM polling to support any of the hot keys you use,
 393           unselecting this option will save about 1kB of memory.
 394
 395           ThinkPads T40 and newer, R52 and newer, and X31 and newer are
 396           unlikely to need NVRAM polling in their latest BIOS versions.
 397
 398           NVRAM polling can detect at most the following keys: ThinkPad/Access
 399           IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
 400           Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).
 401
 402           If you are not sure, say Y here.  The driver enables polling only if

 506
 507           ACPI-WMI is a proprietary extension to ACPI to expose parts of the
 508           ACPI firmware to userspace - this is done through various vendor
 509           defined methods and data blocks in a PNP0C14 device, which are then
 510           made available for userspace to call.
 511
 512           The implementation of this in Linux currently only exposes this to
 513           other kernel space drivers.
 514
 515           This driver is a required dependency to build the firmware specific
 516           drivers needed on many machines, including Acer and HP laptops.

 541           the extra buttons generate standard ACPI events that go through
 542           /proc/acpi/events, and (on some models) adds support for changing the
 543           display brightness and output, switching the LCD backlight on and off,
 544           and most importantly, allows you to blink those fancy LEDs intended
 545           for reporting mail and wireless status.
 546
 547           Note: display switching code is currently considered EXPERIMENTAL,
 548           toying with these values may even lock your machine.

 589
 590           On these machines, all system configuration is handled through the

 595           This driver differs from the non-ACPI Toshiba laptop driver (located
