C Specification

The VkPhysicalDeviceShaderDemoteToHelperInvocationFeatures structure is defined as:

// Provided by VK_VERSION_1_3
typedef struct VkPhysicalDeviceShaderDemoteToHelperInvocationFeatures {
    VkStructureType    sType;
    void*              pNext;
    VkBool32           shaderDemoteToHelperInvocation;
} VkPhysicalDeviceShaderDemoteToHelperInvocationFeatures;

or the equivalent

// Provided by VK_EXT_shader_demote_to_helper_invocation
typedef VkPhysicalDeviceShaderDemoteToHelperInvocationFeatures VkPhysicalDeviceShaderDemoteToHelperInvocationFeaturesEXT;

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

  • shaderDemoteToHelperInvocation indicates whether the implementation supports the SPIR-V DemoteToHelperInvocationEXT capability.

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

Valid Usage (Implicit)

  • VUID-VkPhysicalDeviceShaderDemoteToHelperInvocationFeatures-sType-sType
    sType must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_DEMOTE_TO_HELPER_INVOCATION_FEATURES
