| help |
| 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. |
| |
| This driver is a required dependency to build the firmware specific |
| drivers needed on many machines, including Acer and HP laptops. |

| any ACPI-WMI devices. |
