C Specification

The VkPhysicalDeviceShaderSubgroupExtendedTypesFeatures structure is defined as:

// Provided by VK_VERSION_1_2
typedef struct VkPhysicalDeviceShaderSubgroupExtendedTypesFeatures {
    VkStructureType    sType;
    void*              pNext;
    VkBool32           shaderSubgroupExtendedTypes;
} VkPhysicalDeviceShaderSubgroupExtendedTypesFeatures;

or the equivalent

// Provided by VK_KHR_shader_subgroup_extended_types
typedef VkPhysicalDeviceShaderSubgroupExtendedTypesFeatures VkPhysicalDeviceShaderSubgroupExtendedTypesFeaturesKHR;

Members

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.

Description

  • shaderSubgroupExtendedTypes is a boolean specifying whether subgroup operations can use 8-bit integer, 16-bit integer, 64-bit integer, 16-bit floating-point, and vectors of these types in group operations with subgroup scope, if the implementation supports the types.

If the VkPhysicalDeviceShaderSubgroupExtendedTypesFeatures 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 VkPhysicalDeviceShaderSubgroupExtendedTypesFeatures, 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)
  • VUID-VkPhysicalDeviceShaderSubgroupExtendedTypesFeatures-sType-sType
    sType must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_SUBGROUP_EXTENDED_TYPES_FEATURES
