## Name

VkPhysicalDeviceComputeShaderDerivativesFeaturesKHR - Structure describing compute shader derivative features that can be supported by an implementation

Loading… please wait.

## C Specification

The `VkPhysicalDeviceComputeShaderDerivativesFeaturesKHR` structure is defined as:

    // Provided by VK_KHR_compute_shader_derivatives
    typedef struct VkPhysicalDeviceComputeShaderDerivativesFeaturesKHR {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           computeDerivativeGroupQuads;
        VkBool32           computeDerivativeGroupLinear;
    } VkPhysicalDeviceComputeShaderDerivativesFeaturesKHR;

or the equivalent

    // Provided by VK_NV_compute_shader_derivatives
    typedef VkPhysicalDeviceComputeShaderDerivativesFeaturesKHR VkPhysicalDeviceComputeShaderDerivativesFeaturesNV;

## Members

This structure describes the following features:

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `computeDerivativeGroupQuads` indicates that the implementation supports the `ComputeDerivativeGroupQuadsKHR` SPIR-V capability.

- `computeDerivativeGroupLinear` indicates that the implementation supports the `ComputeDerivativeGroupLinearKHR` SPIR-V capability.

## Description

See Quad shader scope for more information.

If the `VkPhysicalDeviceComputeShaderDerivativesFeaturesKHR`. 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 `VkPhysicalDeviceComputeShaderDerivativesFeaturesKHR`., 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-VkPhysicalDeviceComputeShaderDerivativesFeaturesKHR-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_COMPUTE_SHADER_DERIVATIVES_FEATURES_KHR`
