DXGKARGCB_PINFRAMEBUFFERFORSAVE structure

Description

The DXGKARGCB_PINFRAMEBUFFERFORSAVE structure contains the arguments used by the DXGKCB_PINFRAMEBUFFERFORSAVE callback function, to pin the frame buffer for save.

Members

PhysicalAdapterIndex [in]

The index of the physical adapter.

CommitSize [in]

The size, in bytes, that the driver requires to pin. This size must be a multiple of PAGE_SIZE and must be less than or equal to the maximum size specified by the driver during initialization in DXGK_FRAMEBUFFERSAVEAREA (during DXGKQAITYPE_FRAMEBUFFERSAVESIZE).

pMdl [out]

An MDL pointing to the pages of the frame buffer save area. These pages are guaranteed to be mapped to the IoMmu.

Remarks

See IOMMU-based GPU isolation for more information.
