# VkPhysicalDeviceShaderSubgroupRotateFeatures(3) Manual Page

## Name

VkPhysicalDeviceShaderSubgroupRotateFeatures - Structure describing whether subgroup rotation is enabled

Loading… please wait.

## C Specification

The `VkPhysicalDeviceShaderSubgroupRotateFeatures` structure is defined as:

    // Provided by VK_VERSION_1_4
    typedef struct VkPhysicalDeviceShaderSubgroupRotateFeatures {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           shaderSubgroupRotate;
        VkBool32           shaderSubgroupRotateClustered;
    } VkPhysicalDeviceShaderSubgroupRotateFeatures;

or the equivalent

    // Provided by VK_KHR_shader_subgroup_rotate
    typedef VkPhysicalDeviceShaderSubgroupRotateFeatures VkPhysicalDeviceShaderSubgroupRotateFeaturesKHR;

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

## Description

- `shaderSubgroupRotate` specifies whether shader modules can declare the `GroupNonUniformRotateKHR` capability.

- `shaderSubgroupRotateClustered` specifies whether shader modules can use the `ClusterSize` operand to `OpGroupNonUniformRotateKHR`.

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

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceShaderSubgroupRotateFeatures-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_SUBGROUP_ROTATE_FEATURES`
