DXGKCB_UNPINFRAMEBUFFERFORSAVE callback function

Description

A kernel-mode display miniport driver calls DXGKCB_UNPINFRAMEBUFFERFORSAVE to release the mapping that was set in a prior call to DXGKCB_PINFRAMEBUFFERFORSAVE2 or DXGKCB_PINFRAMEBUFFERFORSAVE.

Parameters

hAdapter [in]

A handle to a display adapter. The driver provides this handle for the master/lead device in the LDA chain.

pUnpinFrameBufferForSave [in]

A pointer to the DXGKARGCB_UNPINFRAMEBUFFERFORSAVE structure that contains a handle to the memory to be unmapped.

Return value

DXGKCB_UNPINFRAMEBUFFERFORSAVE returns STATUS_SUCCESS if the operation succeeds. Otherwise, it returns one of the error codes defined in Ntstatus.h.

Remarks

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

See IOMMU-based GPU isolation for more information.
