help
|
|
This option enables support for the ACPI-WMI driver core.
|
|
|
|
The ACPI-WMI interface is a proprietary extension of ACPI allowing
|
|
the platform firmware to expose WMI (Windows Management Instrumentation)
|
|
objects used for managing various aspects of the underlying system.
|
|
Mapping between ACPI control methods and WMI objects happens through
|
|
special mapper devices (PNP0C14) defined inside the ACPI tables.
|
|
|
|
Enabling this option is necessary for building the vendor specific
|
|
ACPI-WMI client drivers for Acer, Dell an HP machines (among others).
|
|
|
|
It is safe to enable this option even for machines that do not contain
|
|
any ACPI-WMI mapper devices at all.

|
|
help
|
|
Say Y here to force the WMI driver core to use the old WMI device naming
|
|
scheme when creating WMI devices. Doing so might be necessary for some
|
|
userspace applications but will cause the registration of WMI devices with
|
|
the same GUID to fail in some corner cases.
