DXGKARG_SETFLIPQUEUELOGBUFFER structure (d3dkmddi.h)
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.
