VkDataGraphPipelineConstantARM

Structure specifying parameters of a data graph pipeline constant

The VkDataGraphPipelineConstantARM structure is defined as:

typedef struct VkDataGraphPipelineConstantARM {
    VkStructureType sType;
    const void* pNext;
    uint32_t id;
    const void* pConstantData;
} VkDataGraphPipelineConstantARM;
  • sType is a VkStructureType value identifying this structure.
  • pNext is a pointer to a structure extending this structure.
  • id is the unique identifier of the graph constant this structure describes.
  • pConstantData is a pointer to the data for this graph constant.

The size and layout of the data pointed to by pConstantData is specified by a specific structure in the pNext chain for each type of graph constant.

For graph constants of tensor type, the layout of the data is specified by a VkTensorDescriptionARM structure. The data must be laid out according to the following members of this structure:

The presence of a VkDataGraphPipelineConstantTensorSemiStructuredSparsityInfoARM structure in the pNext chain has no impact on the expected layout of the data pointed to by pConstantData.

Valid Usage

VUID-VkDataGraphPipelineConstantARM-pNext-09775

If the pNext chain of this structure includes one or more VkDataGraphPipelineConstantTensorSemiStructuredSparsityInfoARM structures then it must also include a VkTensorDescriptionARM structure

VUID-VkDataGraphPipelineConstantARM-pNext-09776

If the pNext chain of this structure includes one or more VkDataGraphPipelineConstantTensorSemiStructuredSparsityInfoARM structures then, for each structure, VkDataGraphPipelineConstantTensorSemiStructuredSparsityInfoARM::dimensionmust be less than VkTensorDescriptionARM::dimensionCount

VUID-VkDataGraphPipelineConstantARM-pNext-09777

If the pNext chain of this structure includes a VkDataGraphPipelineConstantTensorSemiStructuredSparsityInfoARM structure then, for each structure, VkTensorDescriptionARM::pDimensions[VkDataGraphPipelineConstantTensorSemiStructuredSparsityInfoARM::dimension] must be a multiple of VkDataGraphPipelineConstantTensorSemiStructuredSparsityInfoARM::groupSize

VUID-VkDataGraphPipelineConstantARM-pNext-09870

If the pNext chain of this structure includes multiple VkDataGraphPipelineConstantTensorSemiStructuredSparsityInfoARM structures then no two structures may have their VkDataGraphPipelineConstantTensorSemiStructuredSparsityInfoARM::dimension member set to the same value

VUID-VkDataGraphPipelineConstantARM-id-09850

If the pNext chain of this structure includes a VkTensorDescriptionARM structure, then its usage member must contain VK_TENSOR_USAGE_DATA_GRAPH_BIT_ARM

VUID-VkDataGraphPipelineConstantARM-pNext-09917

If the pNext chain of this structure includes a VkTensorDescriptionARM structure, then its tiling member must be VK_TENSOR_TILING_LINEAR_ARM

Valid Usage (Implicit)

VUID-VkDataGraphPipelineConstantARM-sType-sType

sType must be VK_STRUCTURE_TYPE_DATA_GRAPH_PIPELINE_CONSTANT_ARM

VUID-VkDataGraphPipelineConstantARM-pNext-pNext

Each pNext member of any structure (including this one) in the pNext chain must be either NULL or a pointer to a valid instance of VkDataGraphPipelineConstantTensorSemiStructuredSparsityInfoARM or VkTensorDescriptionARM

VUID-VkDataGraphPipelineConstantARM-sType-unique

The sType value of each structure in the pNext chain must be unique, with the exception of structures of type VkDataGraphPipelineConstantTensorSemiStructuredSparsityInfoARM

VUID-VkDataGraphPipelineConstantARM-pConstantData-parameter

pConstantData must be a pointer value
