DXGKARG_SETFLIPQUEUELOGBUFFER structure (d3dkmddi.h)

  • Article

The DXGKARG_SETFLIPQUEUELOGBUFFER structure contains parameters for the driver's DXGKDDI_SETFLIPQUEUELOGBUFFER callback function.

Syntax

typedef struct _DXGKARG_SETFLIPQUEUELOGBUFFER {
  D3DDDI_VIDEO_PRESENT_SOURCE_ID VidPnSourceId;
  UINT                           LayerIndex;
  UINT                           NumberOfEntries;
  DXGK_FLIPQUEUE_LOG_ENTRY       *LogBufferAddress;
} DXGKARG_SETFLIPQUEUELOGBUFFER;

Members

VidPnSourceId

[in] A D3DDDI_VIDEO_PRESENT_SOURCE_ID value that identifies the VidPn source ID for which the flip queue log buffer is being provided.

LayerIndex

[in] A zero-based index value that identifies the MPO plane index for which the flip queue log buffer is being provided.

NumberOfEntries

[in] The number of entries in the flip queue log buffer that LogBufferAddress points to.

LogBufferAddress

[in] Pointer to an array of DXGK_FLIPQUEUE_LOG_ENTRY structures in the flip queue log buffer. This value is the kernel-mode CPU virtual address of the flip queue log buffer in non-paged memory. LogBufferAddress is NULL if the OS is about to destroy the current flip queue log buffer.

Remarks

See Obtaining present statistics for queued flips for more information.
