C Specification

The VkPhysicalDeviceComputeShaderDerivativesFeaturesNV structure is defined as:

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

Members

This structure describes the following features:

Description

  • sType is the type of this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • computeDerivativeGroupQuads indicates that the implementation supports the ComputeDerivativeGroupQuadsNV SPIR-V capability.

  • computeDerivativeGroupLinear indicates that the implementation supports the ComputeDerivativeGroupLinearNV SPIR-V capability.

See Quad shader scope for more information.

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

Valid Usage (Implicit)
  • VUID-VkPhysicalDeviceComputeShaderDerivativesFeaturesNV-sType-sType
    sType must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_COMPUTE_SHADER_DERIVATIVES_FEATURES_NV
