DXGKCB_MAPFRAMEBUFFERPOINTER callback function (d3dkmddi.h)
DXGKCB_MAPFRAMEBUFFERPOINTER obtains a pointer to a subregion of the section object that was created for each physical adapter.
Syntax
DXGKCB_MAPFRAMEBUFFERPOINTER DxgkcbMapframebufferpointer;
NTSTATUS DxgkcbMapframebufferpointer(
[in] IN_CONST_HANDLE hAdapter,
[in/out] INOUT_PDXGKARGCB_MAPFRAMEBUFFERPOINTER pMapFrameBufferPointer
)
{...}
Parameters
[in] hAdapter
A handle to a display adapter. The driver provides this handle for the master/lead device in the LDA chain.
[in/out] pMapFrameBufferPointer
Pointer to DXGKARGCB_MAPFRAMEBUFFERPOINTER structure that contains a pointer to the subregion of the section object.
Return value
DXGKCB_MAPFRAMEBUFFERPOINTER returns STATUS_SUCCESS if the operation succeeds. Otherwise, it returns an appropriate NTSTATUS error code.
Remarks
DXGKCB_XXX functions are implemented by Dxgkrnl. To use this callback function, set the appropriate members of DXGKARGCB_MAPFRAMEBUFFERPOINTER and then call DxgkCbMapFrameBufferPointer via the DXGKRNL_INTERFACE.
See IOMMU-based GPU isolation for more information.
