DXGK_QUERYSEGMENTMEMORYSTATE structure (d3dkmddi.h)
DXGK_QUERYSEGMENTMEMORYSTATE is used with DxgkDdiQueryAdapterInfo to query invalid graphics processing unit (GPU) memory ranges.
Syntax
typedef struct _DXGK_QUERYSEGMENTMEMORYSTATE {
WORD DriverSegmentId;
WORD PhysicalAdapterIndex;
union {
UINT NumInvalidMemoryRanges;
UINT NumUEFIFrameBufferRanges;
};
UINT NumInvalidMemoryRanges;
DXGK_MEMORYRANGE *pMemoryRanges;
} DXGK_QUERYSEGMENTMEMORYSTATE, DXGK_SEGMENTMEMORYSTATE;
Members
DriverSegmentId
A 1-based segment identifier of a local GPU memory segment.
PhysicalAdapterIndex
Physical adapter index in a linked display adapter link.
NumInvalidMemoryRanges
The number of entries in the pMemoryRanges array. This is the value returned by the kernel mode driver in DXGK_SEGMENTDESCRIPTOR4.
NumUEFIFrameBufferRanges
pMemoryRanges
Array of DXGK_MEMORYRANGE structures for the invalid memory ranges.
