DXGKCB_MAPFRAMEBUFFERPOINTER callback function

Description

DXGKCB_MAPFRAMEBUFFERPOINTER obtains a pointer to a subregion of the section object that was created for each physical adapter.

Parameters

hAdapter [in]

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

pMapFrameBufferPointer [in/out]

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.
