DXGKCB_PINFRAMEBUFFERFORSAVE callback function

Description

A kernel-mode display miniport driver calls DXGKCB_PINFRAMEBUFFERFORSAVE to pin down the entire frame buffer at once.

Parameters

hAdapter [in]

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

pPinFrameBufferForSave [in/out]

Pointer to a DXGKARGCB_PINFRAMEBUFFERFORSAVE structure that contains information about the frame buffer to save.

Return value

DXGKCB_PINFRAMEBUFFERFORSAVE 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_PINFRAMEBUFFERFORSAVE and then call DxgkCbPinFrameBufferForSave via the DXGKRNL_INTERFACE.

See IOMMU-based GPU isolation for more information.
