DXGKDDI_CHECKMULTIPLANEOVERLAYSUPPORT2 callback function (d3dkmddi.h)
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.
Syntax
DXGKDDI_CHECKMULTIPLANEOVERLAYSUPPORT2 DxgkddiCheckmultiplaneoverlaysupport2;
NTSTATUS DxgkddiCheckmultiplaneoverlaysupport2(
IN_CONST_HANDLE hAdapter,
IN_OUT_PDXGKARG_CHECKMULTIPLANEOVERLAYSUPPORT2 pCheckMultiPlaneOverlaySupport
)
{...}
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.
