-description

The DXGKARGCB_CLOSE_PHYSICAL_MEMORY_OBJECT structure contains the information used by the DXGKCB_CLOSEPHYSICALMEMORYOBJECT callback function to close a physical memory object.

-struct-fields

-field hAdapterMemoryObject

The adapter 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.
