DXGKDDI_CHECKMULTIPLANEOVERLAYSUPPORT2 callback function

Description

The DirectX graphics kernel subsystem calls a WDDM 2.0 driver's DXGKDDI_CHECKMULTIPLANEOVERLAYSUPPORT2 callback routine to determine whether a specific multi-plane overlay configuration is supported. It must be implemented by WDDM 2.0 drivers that support multi-plane overlays. This function has been replaced with DXGKDDI_CHECKMULTIPLANEOVERLAYSUPPORT3.

Parameters

`hAdapter`

Identifies the adapter containing the overlay hardware. The display miniport driver previously provided this handle to the DirectX graphics kernel subsystem in the MiniportDeviceContext output parameter of the DxgkDdiAddDevice function.

`pCheckMultiPlaneOverlaySupport`

A pointer to a DXGKARG_CHECKMULTIPLANEOVERLAYSUPPORT2 structure that describes the surfaces and display options to present.

Return value

If this routine succeeds, it returns NTSTATUS_SUCCESS. The driver should always return a success code.

Remarks

The kernel-mode driver reports whether the specified configuration is supported. The kernel-mode driver should not raise or lower the available bandwidth in anticipation of this configuration getting set.
