Description

DXGKARG_SETNATIVEFENCELOGBUFFER is the input structure for DxgkDdiSetNativeFenceLogBuffer.

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`

[in] The read/write GPU VA of the log buffer in user process address space.

`LogBufferSystemProcessGpuVa`

[in] The read/write GPU VA of the log buffer in system address space.

`Flags`

[in] A DXGKARG_SETNATIVEFENCELOGBUFFER_FLAGS structure that contains flags for writing a payload into the native fence log buffer.

`Reserved[32]`

Reserved for system use.
