DXGK_WDDMDEVICECAPS structure

Description

The DXGK_WDDMDEVICECAPS structure identifies the kernel-mode driver's WDDM capabilities.

Members

WDDMVersion

The capabilities of a display miniport driver that the driver provides through a call to its DxgkDdiQueryAdapterInfo function. This value is the same as the WDDMVersion value in DXGK_DRIVERCAPS structure.

Remarks

A kernel-mode driver returns its WDDM capabilities in this structure, in response to a DxgkDdiQueryAdapterInfo request for a DXGK_QUERYADAPTERINFOTYPE value of type DXGKQAITYPE_WDDMDEVICECAPS.

The OS queries for these capabilities during device initialization, after DxgkDdiAddDevice returns but before DxgkDdiStartDevice is called.
