Description

DXGKCB_CLOSEPHYSICALMEMORYOBJECT closes a physical memory object.

Parameters

pArgs [in]

Pointer to a DXGKARGCB_CLOSE_PHYSICAL_MEMORY_OBJECT structure that contains information about the physical memory object to close.

Remarks

If the driver chooses to specify hAdapterMemoryObject as part of the DXGKCB_DESTROYPHYSICALMEMORYOBJECT call, then it is not necessary to close it via DXGKCB_CLOSEPHYSICALMEMORYOBJECT as well.

See IOMMU DMA remapping for more information.

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