# VkPhysicalDeviceShaderRelaxedExtendedInstructionFeaturesKHR(3) Manual Page

## Name

VkPhysicalDeviceShaderRelaxedExtendedInstructionFeaturesKHR - Structure describing support for VK_KHR_shader_relaxed_extended_instruction an implementation

Loading… please wait.

## C Specification

The `VkPhysicalDeviceShaderRelaxedExtendedInstructionFeaturesKHR` structure is defined as:

    // Provided by VK_KHR_shader_relaxed_extended_instruction
    typedef struct VkPhysicalDeviceShaderRelaxedExtendedInstructionFeaturesKHR {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           shaderRelaxedExtendedInstruction;
    } VkPhysicalDeviceShaderRelaxedExtendedInstructionFeaturesKHR;

## 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.

- `shaderRelaxedExtendedInstruction` specifies whether the implementation supports SPIR-V modules that use the `SPV_KHR_relaxed_extended_instruction` extension.

## Description

If the `VkPhysicalDeviceShaderRelaxedExtendedInstructionFeaturesKHR` 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 `VkPhysicalDeviceShaderRelaxedExtendedInstructionFeaturesKHR`, 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-VkPhysicalDeviceShaderRelaxedExtendedInstructionFeaturesKHR-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_RELAXED_EXTENDED_INSTRUCTION_FEATURES_KHR`
