VkExecutionGraphPipelineScratchSizeAMDX
Structure describing the scratch space required to dispatch an execution graph
The VkExecutionGraphPipelineScratchSizeAMDX
structure is defined as:
typedef struct VkExecutionGraphPipelineScratchSizeAMDX {
VkStructureType sType;
void* pNext;
VkDeviceSize minSize;
VkDeviceSize maxSize;
VkDeviceSize sizeGranularity;
} VkExecutionGraphPipelineScratchSizeAMDX;
sType
is a VkStructureType value identifying this structure.pNext
isNULL
or a pointer to a structure extending this structure.minSize
indicates the minimum scratch space required for dispatching the queried execution graph.maxSize
indicates the maximum scratch space that can be used for dispatching the queried execution graph.sizeGranularity
indicates the granularity at which the scratch space can be increased fromminSize
.
Applications can use any amount of scratch memory greater than
minSize
for dispatching a graph, however only the values equal to
minSize
+ an integer multiple of sizeGranularity
will be used.
Greater values may result in higher performance, up to maxSize
which
indicates the most memory that an implementation can use effectively.
