## Name

VkDataGraphPipelineConstantTensorSemiStructuredSparsityInfoARM - Structure specifying semi-structured sparsity parameters of a tensor data graph pipeline constant

Loading… please wait.

## C Specification

The `VkDataGraphPipelineConstantTensorSemiStructuredSparsityInfoARM` structure is defined as:

    // Provided by VK_ARM_data_graph with VK_ARM_tensors
    typedef struct VkDataGraphPipelineConstantTensorSemiStructuredSparsityInfoARM {
        VkStructureType    sType;
        const void*        pNext;
        uint32_t           dimension;
        uint32_t           zeroCount;
        uint32_t           groupSize;
    } VkDataGraphPipelineConstantTensorSemiStructuredSparsityInfoARM;

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `dimension` is the dimension of the tensor along which its data is sparse.

- `zeroCount` is the number of tensor elements that must be zero in every group of `groupSize` elements.

- `groupSize` is the number of tensor elements in a group.

## Description

Note | This extension does not provide applications with a way of knowing which combinations of `dimension`, `zeroCount`, and `groupSize` an implementation can take advantage of. Providing sparsity information for a graph constant is always valid and recommended, regardless of the specific combinations an implementation can take advantage of. When they can not take advantage of the sparsity information, implementations will ignore it and treat the data as dense.

Valid Usage (Implicit)

- VUID-VkDataGraphPipelineConstantTensorSemiStructuredSparsityInfoARM-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_DATA_GRAPH_PIPELINE_CONSTANT_TENSOR_SEMI_STRUCTURED_SPARSITY_INFO_ARM`
