## Name

VkPhysicalDeviceShaderSubgroupExtendedTypesFeatures - Structure describing the extended types subgroups support feature for an implementation

Loading… please wait.

## 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. `VkPhysicalDeviceShaderSubgroupExtendedTypesFeatures` can also be used in the `pNext` chain of VkDeviceCreateInfo to selectively enable these features.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceShaderSubgroupExtendedTypesFeatures-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_SUBGROUP_EXTENDED_TYPES_FEATURES`
