| 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. |
