0023 This driver adds support for the ACPI-WMI (Windows Management
0024 Instrumentation) mapper device (PNP0C14) found on some systems.
0025
0026 ACPI-WMI is a proprietary extension to ACPI to expose parts of the
0027 ACPI firmware to userspace - this is done through various vendor
0028 defined methods and data blocks in a PNP0C14 device, which are then
0029 made available for userspace to call.
0030
0031 The implementation of this in Linux currently only exposes this to
0032 other kernel space drivers.
0033
0034 This driver is a required dependency to build the firmware specific
0035 drivers needed on many machines, including Acer and HP laptops.
0036
0037 It is safe to enable this driver even if your DSDT doesn't define
0038 any ACPI-WMI devices.
