C Specification

The VkPipelineShaderStageRequiredSubgroupSizeCreateInfoEXT structure is defined as:

typedef struct VkPipelineShaderStageRequiredSubgroupSizeCreateInfoEXT {
    VkStructureType    sType;
    void*              pNext;
    uint32_t           requiredSubgroupSize;
} VkPipelineShaderStageRequiredSubgroupSizeCreateInfoEXT;


Valid Usage
  • requiredSubgroupSize must be a power-of-two integer

  • requiredSubgroupSize must be greater or equal to minSubgroupSize

  • requiredSubgroupSize must be less than or equal to maxSubgroupSize


If a VkPipelineShaderStageRequiredSubgroupSizeCreateInfoEXT structure is included in the pNext chain of VkPipelineShaderStageCreateInfo, it specifies that the pipeline shader stage being compiled has a required subgroup size.
