DXGK_VIRTUALGPUSEGMENTINFO structure (dispmprt.h)

Information about the virtual GPU segment info.

Syntax

typedef struct _DXGK_VIRTUALGPUSEGMENTINFO {
  ULONG  DriverSegmentId;
  UINT64 Size;

  UINT64 MinSegmentOffset;
  UINT64 MaxSegmentOffset;
  UINT   PrivateDriverData;
} DXGK_VIRTUALGPUSEGMENTINFO, *PDXGK_VIRTUALGPUSEGMENTINFO;

Members

DriverSegmentId

The driver Id of the physical memory segment, which was enumerated by Dxgkrnl. The value starts from 1.

Size

Size in this memory segment, which is needed in the vGPU.

Alignment

Allocation alignment in the memory segment in bytes. This value must be a multiple of 4096 bytes or zero.

MinSegmentOffset

Optionally, the driver can specify a range in the segment where this allocation must be located. If there is no range restriction, set these values to zero. This could be used, for example, when a portion of the VPR range needs to be assigned to a vGPU.

MaxSegmentOffset

Optionally, the driver can specify a range in the segment where this allocation must be located. If there is no range restriction, set these values to zero. This could be used, for example, when a portion of the VPR range needs to be assigned to a vGPU.

PrivateDriverData

Allocation driver private data.
