- 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.

- This driver adds support for access to certain system settings
- on "legacy free" Toshiba laptops. These laptops can be recognized by
- their lack of a BIOS setup menu and APM support.
-
- 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.

+ This driver adds support for the ACPI-WMI (Windows Management

+
+ 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.

+ select INPUT_POLLDEV
+ select NET
+ select RFKILL
+ select BACKLIGHT_CLASS_DEVICE
+ ---help---
+ This driver adds support for access to certain system settings
+ on "legacy free" Toshiba laptops. These laptops can be recognized by
+ their lack of a BIOS setup menu and APM support.
+
+ 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.
