C Specification

The VkPipelineShaderStageRequiredSubgroupSizeCreateInfoEXT structure is defined as:

// Provided by VK_EXT_subgroup_size_control
typedef struct VkPipelineShaderStageRequiredSubgroupSizeCreateInfoEXT {
    VkStructureType    sType;
    void*              pNext;
    uint32_t           requiredSubgroupSize;
} VkPipelineShaderStageRequiredSubgroupSizeCreateInfoEXT;

Members

  • sType is the type of this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • requiredSubgroupSize is an unsigned integer value specifying the required subgroup size for the newly created pipeline shader stage.

Description

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.

Valid Usage
  • VUID-VkPipelineShaderStageRequiredSubgroupSizeCreateInfoEXT-requiredSubgroupSize-02760
    requiredSubgroupSize must be a power-of-two integer

  • VUID-VkPipelineShaderStageRequiredSubgroupSizeCreateInfoEXT-requiredSubgroupSize-02761
    requiredSubgroupSize must be greater or equal to minSubgroupSize

  • VUID-VkPipelineShaderStageRequiredSubgroupSizeCreateInfoEXT-requiredSubgroupSize-02762
    requiredSubgroupSize must be less than or equal to maxSubgroupSize

Valid Usage (Implicit)
  • VUID-VkPipelineShaderStageRequiredSubgroupSizeCreateInfoEXT-sType-sType
    sType must be VK_STRUCTURE_TYPE_PIPELINE_SHADER_STAGE_REQUIRED_SUBGROUP_SIZE_CREATE_INFO_EXT
