VkPhysicalDeviceShaderDemoteToHelperInvocationFeatures

The VkPhysicalDeviceShaderDemoteToHelperInvocationFeatures structure is defined as:

typedef struct VkPhysicalDeviceShaderDemoteToHelperInvocationFeatures {
    VkStructureType sType;
    void* pNext;
    VkBool32 shaderDemoteToHelperInvocation;
} VkPhysicalDeviceShaderDemoteToHelperInvocationFeatures;

or the equivalent

typedef VkPhysicalDeviceShaderDemoteToHelperInvocationFeatures VkPhysicalDeviceShaderDemoteToHelperInvocationFeaturesEXT;

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.
• 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. If the application wishes to use a VkDevice with any features described by VkPhysicalDeviceShaderDemoteToHelperInvocationFeatures, 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.
