DXGK_NATIVE_FENCE_LOG_ENTRY structure (d3dukmdt.h)

The DXGK_NATIVE_FENCE_LOG_ENTRY structure contains a native fence log entry.

Syntax

typedef struct _DXGK_NATIVE_FENCE_LOG_ENTRY {
  UINT64        FenceValue;
  D3DKMT_HANDLE hNativeFence;
  UINT          OperationType;
  UINT64        Reserved0;
  UINT64        FenceObservedGpuTimestamp;
  UINT64        Reserved1;
  UINT64        FenceEndGpuTimestamp;
} DXGK_NATIVE_FENCE_LOG_ENTRY;

Members

FenceValue

UMD payload: The newly signaled/unblocked fence value.

hNativeFence

UMD payload: User-mode D3DKMT_HANDLE of the native fence to which this operation belongs.

OperationType

UMD payload: A DXGK_FENCE_LOG_OPERATION value that specifies the type of the operation.

Reserved0

Reserved for alignment.

FenceObservedGpuTimestamp

GPU Payload: When OperationType is OPERATION_WAIT_UNBLOCKED, specifies the GPU time at which an unresolved wait command was seen by the engine and stalled the HWQueue.

Reserved1

Reserved for alignment.

FenceEndGpuTimestamp

GPU Payload: GPU time at which the fence operation completed on the GPU.
