DXGKCB_FREECONTIGUOUSMEMORY callback function

Description

DXGKCB_FREECONTIGUOUSMEMORY frees a range of physically contiguous memory that was allocated by DXGKCB_ALLOCATECONTIGUOUSMEMORY.

Parameters

hAdapter [in]

Handle to a display adapter.

pFreeContiguousMemory [in]

Pointer to a DXGKARGCB_FREECONTIGUOUSMEMORY structure that contains a handle to the contiguous memory to be freed.

Return value

Return STATUS_SUCCESS if the operation succeeds. Otherwise, return an appropriate NTSTATUS error code.

Remarks

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

See IOMMU-based GPU isolation for more information.
