Multiplane overlay functions implemented by the user-mode driver

This section contains functions that a Windows Display Driver Model (WDDM) 1.3 and later user-mode display driver must implement in order to support multiplane overlays.

The driver supplies pointers to DXGI multiplane overlay functions through members of the DXGI1_3_DDI_BASE_FUNCTIONS structure in a call to the user-mode display driver's adapter-specific CreateDevice(D3D10) function. For more info, see Supporting the DXGI DDI.

The driver supplies pointers to Microsoft Direct3D multiplane overlay functions through members of the D3DDDI_DEVICEFUNCS structure in a call to the driver's CreateDevice function.

TopicDescription

pfnCheckMultiPlaneOverlaySupport (D3D)

Called by the Direct3D runtime to check the details on hardware support for multiplane overlays.

pfnCheckMultiPlaneOverlaySupport (DXGI)

Called by the Microsoft DirectX Graphics Infrastructure (DXGI) runtime to check the details on hardware support for multiplane overlays.

pfnGetMultiPlaneOverlayCaps

Called by the DXGI runtime to request that the user-mode display driver get basic overlay plane capabilities. Optionally implemented by WDDM 1.3 and later user-mode display drivers.

pfnGetMultiplaneOverlayGroupCaps

Called by the DXGI runtime to request that the user-mode display driver get a group of overlay plane capabilities. Optionally implemented by WDDM 1.3 and later user-mode display drivers.

pfnPresentMultiplaneOverlay (D3D)

Called by the Direct3D runtime to notify the user-mode display driver that an application finished rendering and requests that the driver display the source surface by either copying or flipping or that the driver perform a color-fill operation. Must be implemented by WDDM 1.3 or later drivers that support multiplane overlays.

pfnPresentMultiplaneOverlay (DXGI)

Must be implemented by WDDM 1.3 or later drivers that support multiplane overlays.
