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. 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.
