This driver adds support for the ACPI-WMI (Windows Management
|
||||
Instrumentation) mapper device (PNP0C14) found on some systems.
|
||||
|
||||
NOTE: You will need another driver or userspace application on top of
|
||||
this to actually use anything defined in the ACPI-WMI mapper.
|
||||
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.
