VkPhysicalDeviceComputeShaderDerivativesFeaturesKHR

The VkPhysicalDeviceComputeShaderDerivativesFeaturesKHR structure is defined as:

typedef struct VkPhysicalDeviceComputeShaderDerivativesFeaturesKHR {
    VkStructureType sType;
    void* pNext;
    VkBool32 computeDerivativeGroupQuads;
    VkBool32 computeDerivativeGroupLinear;
} VkPhysicalDeviceComputeShaderDerivativesFeaturesKHR;

or the equivalent

typedef VkPhysicalDeviceComputeShaderDerivativesFeaturesKHR VkPhysicalDeviceComputeShaderDerivativesFeaturesNV;

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.

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