22 | help | |
23 | This driver adds support for the ACPI-WMI (Windows Management | |
24 | Instrumentation) mapper device (PNP0C14) found on some systems. | |
25 | ||
26 | ACPI-WMI is a proprietary extension to ACPI to expose parts of the | |
27 | ACPI firmware to userspace - this is done through various vendor | |
28 | defined methods and data blocks in a PNP0C14 device, which are then | |
29 | made available for userspace to call. | |
30 | ||
31 | The implementation of this in Linux currently only exposes this to | |
32 | other kernel space drivers. | |
33 | ||
34 | This driver is a required dependency to build the firmware specific | |
35 | drivers needed on many machines, including Acer and HP laptops. | |
36 | ||
37 | It is safe to enable this driver even if your DSDT doesn't define | |
38 | any ACPI-WMI devices. | |
