The DXGK_NATIVE_FENCE_LOG_ENTRY structure contains a native fence log entry.
FenceValueUMD payload: The newly signaled/unblocked fence value.
hNativeFenceUMD payload: User-mode D3DKMT_HANDLE of the native fence to which this operation belongs.
OperationTypeUMD payload: A DXGK_FENCE_LOG_OPERATION value that specifies the type of the operation.
Reserved0Reserved for alignment.
FenceObservedGpuTimestampGPU 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.
Reserved1Reserved for alignment.
FenceEndGpuTimestampGPU Payload: GPU time at which the fence operation completed on the GPU.
