DXGKCB_MAPCONTEXTALLOCATION callback function

Description

A kernel-mode display miniport driver calls DXGKCB_MAPCONTEXTALLOCATION to map a graphics processing unit (GPU) virtual address to the specified context allocation.

Parameters

hAdapter [in]

A handle to the display adapter.

pArgs [in]

Pointer to a DXGKARGCB_MAPCONTEXTALLOCATION structure that describes the operation.

Return value

DXGKCB_MAPCONTEXTALLOCATION returns a D3DGPU_VIRTUAL_ADDRESS if successful, NULL otherwise.

Remarks

This device driver interface (DDI) behaves like its user-mode counterpart; see pfnMapGpuVirtualAddressCb for more details.

DXGKCB_XXX functions are implemented by Dxgkrnl. To use this callback function, set the members of DXGKARGCB_MAPCONTEXTALLOCATION and then call DxgkCbMapContextAllocation via the DXGKRNL_INTERFACE.
