DXGKARG_SETNATIVEFENCELOGBUFFER is the input structure for DxgkDdiSetNativeFenceLogBuffer.

Syntax

typedef struct _DXGKARG_SETNATIVEFENCELOGBUFFER {
  HANDLE                                hHwQueue;
  UINT                                  NumberOfEntries;
  DXGK_NATIVE_FENCE_LOG_BUFFER          *LogBufferCpuVa;
  D3DGPU_VIRTUAL_ADDRESS                LogBufferGpuVa;
  D3DGPU_VIRTUAL_ADDRESS                LogBufferSystemProcessGpuVa;
  DXGKARG_SETNATIVEFENCELOGBUFFER_FLAGS Flags;
  BYTE                                  Reserved[32];
} DXGKARG_SETNATIVEFENCELOGBUFFER;

Members

hHwQueue

[in] Driver handle of the HWQueue to which this log belongs.

NumberOfEntries

[in] Number of entries in the array of log entries that LogBufferCpuVa points to.

LogBufferCpuVa

[in] The read/write kernel-mode CPU virtual address of the native fence log buffer.

LogBufferGpuVa
