+         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.

 
 

-         NOTE: You will need another driver or userspace application on top of
-         this to actually use anything defined in the ACPI-WMI mapper.
+         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.
