Describes multiplane overlay allocations that content is copied to and from.
A handle to the Microsoft DirectX Graphics Infrastructure (DXGI) context. This handle is opaque to the driver. The driver should assign the handle from the pDXGIContext member of the DXGI_DDI_ARG_PRESENTMULTIPLANEOVERLAY structure that the driver received in a call to its pfnPresentMultiplaneOverlay (DXGI) function to this member.
A handle to the context that the driver submits the copy operation to. The user-mode display driver previously created this context by calling the pfnCreateContextCb function.
The number of additional contexts in the array that the BroadcastContext member specifies.
An array of handles to the additional contexts to broadcast the current present operation to. The D3DDDI_MAX_BROADCAST_CONTEXT constant, which is defined as 64, defines the maximum number of additional contexts that the user-mode display driver can broadcast the current present operation to.
Broadcasting is supported only for flip operations. To broadcast a flip operation, the display miniport driver must support memory mapped I/O (MMIO)-based flips. To indicate support of MMIO flips, the display miniport driver sets the FlipOnVSyncMmIo bit-field flag in the FlipCaps member of the DXGK_DRIVERCAPS structure when its DxgkDdiQueryAdapterInfo function is called.
The original context that the hContext member specifies and that the user-mode display driver presents to is not an element in the BroadcastContext array. For example, if the BroadcastContext array contains one element, the user-mode display driver sends the present operation to the owning context (hContext) and broadcasts to that one additional context.
The number of allocations in the array that the AllocationInfo member specifies. The maximum number is 16, the value of the DXGI_DDI_MAX_MULTIPLANE_OVERLAY_ALLOCATIONS constant.
An array of structures of type DXGIDDI_MULTIPLANE_OVERLAY_ALLOCATION_INFO that specify info about the multiplane overlay allocations.
