VkPhysicalDeviceShaderSubgroupUniformControlFlowFeaturesKHR

Structure describing support for shader subgroup uniform control flow by an implementation

The VkPhysicalDeviceShaderSubgroupUniformControlFlowFeaturesKHR structure is defined as:

typedef struct VkPhysicalDeviceShaderSubgroupUniformControlFlowFeaturesKHR {
    VkStructureType sType;
    void* pNext;
    VkBool32 shaderSubgroupUniformControlFlow;
} VkPhysicalDeviceShaderSubgroupUniformControlFlowFeaturesKHR;

This structure describes the following feature:

  • sType is a VkStructureType value identifying this structure.
  • pNext is NULL or a pointer to a structure extending this structure.
  • shaderSubgroupUniformControlFlow specifies whether the implementation supports the shader execution mode SubgroupUniformControlFlowKHR

If the VkPhysicalDeviceShaderSubgroupUniformControlFlowFeaturesKHR structure is included in the pNext chain of the VkPhysicalDeviceFeatures2 structure passed to vkGetPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. If the application wishes to use a VkDevice with any features described by VkPhysicalDeviceShaderSubgroupUniformControlFlowFeaturesKHR, it must add an instance of the structure, with the desired feature members set to VK_TRUE, to the pNext chain of VkDeviceCreateInfo when creating the VkDevice.

Valid Usage (Implicit)

sType must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_SUBGROUP_UNIFORM_CONTROL_FLOW_FEATURES_KHR
