VkPhysicalDeviceShaderSubgroupRotateFeatures(3)

Name

VkPhysicalDeviceShaderSubgroupRotateFeatures - Structure describing whether subgroup rotation is enabled

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. If the application wishes to use a VkDevice with any features described by VkPhysicalDeviceShaderSubgroupRotateFeatures, 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-VkPhysicalDeviceShaderSubgroupRotateFeatures-sType-sType
sType must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_SUBGROUP_ROTATE_FEATURES
