# VkPhysicalDeviceShaderDemoteToHelperInvocationFeatures(3) Manual Page

## Name

VkPhysicalDeviceShaderDemoteToHelperInvocationFeatures - Structure describing the shader demote to helper invocations features that can be supported by an implementation

Loading… please wait.

## 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:

## Description

- `sType` is the type of 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. `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`
