@ -7,12 +7,11 @@ WMI Driver API
The WMI driver core supports a more modern bus-based interface for interacting
with WMI devices, and an older GUID-based interface. The latter interface is
considered to be deprecated, so new WMI drivers should generally avoid it since
it has some issues with multiple WMI devices and events sharing the same GUIDs
and/or notification IDs. The modern bus-based interface instead maps each
WMI device to a :c:type:`struct wmi_device <wmi_device>`, so it supports
WMI devices sharing GUIDs and/or notification IDs. Drivers can then register
a :c:type:`struct wmi_driver <wmi_driver>`, which will be bound to compatible
WMI devices by the driver core.

Many Dell notebooks made after ~2020 support a WMI-based interface for

This interface is likely used by the `Dell Data Vault` software on Windows,

for example).

5. Use the built-in UEFI diagnostics to view sensor types/values for fan/thermal
related methods (sometimes overwriting static ACPI data fields can be used
to test different sensor type values, since on some machines this data is
not reinitialized upon a warm reset).
