C Specification

The VkPhysicalDeviceShaderMixedFloatDotProductFeaturesVALVE structure is defined as:

// Provided by VK_VALVE_shader_mixed_float_dot_product
typedef struct VkPhysicalDeviceShaderMixedFloatDotProductFeaturesVALVE {
    VkStructureType    sType;
    void*              pNext;
    VkBool32           shaderMixedFloatDotProductFloat16AccFloat32;
    VkBool32           shaderMixedFloatDotProductFloat16AccFloat16;
    VkBool32           shaderMixedFloatDotProductBFloat16Acc;
    VkBool32           shaderMixedFloatDotProductFloat8AccFloat32;
} VkPhysicalDeviceShaderMixedFloatDotProductFeaturesVALVE;

Members

  • sType is a VkStructureType value identifying this structure.

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

  • shaderMixedFloatDotProductFloat16AccFloat32 indicates whether the implementation supports shaders with the DotProductFloat16AccFloat32VALVE capability.

  • shaderMixedFloatDotProductFloat16AccFloat16 indicates whether the implementation supports shaders with the DotProductFloat16AccFloat16VALVE capability.

  • shaderMixedFloatDotProductBFloat16Acc indicates whether the implementation supports shaders with the DotProductBFloat16AccVALVE capability.

  • shaderMixedFloatDotProductFloat8AccFloat32 indicates whether the implementation supports shaders with the DotProductFloat8AccFloat32VALVE capability.

Description

If the VkPhysicalDeviceShaderMixedFloatDotProductFeaturesVALVE 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 VkPhysicalDeviceShaderMixedFloatDotProductFeaturesVALVE, 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)
