DXGKDDI_SETNATIVEFENCELOGBUFFER callback function (d3dkmddi.h)

Dxgkrnl calls DxgkDdiSetNativeFenceLogBuffer to inform the kernel-mode display miniport driver (KMD) of the location of the specified native fence log buffer.

Syntax

DXGKDDI_SETNATIVEFENCELOGBUFFER DxgkddiSetnativefencelogbuffer;

NTSTATUS DxgkddiSetnativefencelogbuffer(
  IN_CONST_PDXGKARG_SETNATIVEFENCELOGBUFFER pSetNativeFenceLogBuffer
)
{...}

Parameters

pSetNativeFenceLogBuffer

[in] Pointer to a DXGKARG_SETNATIVEFENCELOGBUFFER structure that contains the native fence log buffer information.

Return value

DxgkDdiSetNativeFenceLogBuffer returns STATUS_SUCCESS if KMD was able to successfully set the native fence log buffer. Otherwise, it returns an appropriate NTSTATUS error code.

Remarks

Dxgkrnl can destroy and recreate a log buffer. Each time it does, it calls DxgkDdiSetNativeFenceLogBuffer to inform KMD of the new location.
