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

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

On these machines, all system configuration is handled through the
ACPI. This driver is required for access to controls not covered
by the general ACPI drivers, such as LCD brightness, video output,
etc.
This driver differs from the non-ACPI Toshiba laptop driver (located
under "Processor type and features") in several aspects.
Configuration is accessed by reading and writing text files in the
/proc tree instead of by program interface to /dev. Furthermore, no
power management functions are exposed, as those are handled by the
general ACPI drivers.
More information about this driver is available at
<http://memebeam.org/toys/ToshibaAcpiDriver>.
If you have a legacy free Toshiba laptop (such as the Libretto L1
series), say Y.
