C Specification

The VkPhysicalDeviceShaderBfloat16FeaturesKHR structure is defined as:

// Provided by VK_KHR_shader_bfloat16
typedef struct VkPhysicalDeviceShaderBfloat16FeaturesKHR {
    VkStructureType    sType;
    void*              pNext;
    VkBool32           shaderBFloat16Type;
    VkBool32           shaderBFloat16DotProduct;
    VkBool32           shaderBFloat16CooperativeMatrix;
} VkPhysicalDeviceShaderBfloat16FeaturesKHR;

Members

This structure describes the following features:

  • shaderBFloat16Type indicates whether the implementation supports shaders with the BFloat16TypeKHR capability.

  • shaderBFloat16DotProduct indicates whether the implementation supports shaders with the BFloat16DotProductKHR capability.

  • shaderBFloat16CooperativeMatrix indicates whether the implementation supports shaders with the BFloat16CooperativeMatrixKHR capability.

Description

If the VkPhysicalDeviceShaderBfloat16FeaturesKHR 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 VkPhysicalDeviceShaderBfloat16FeaturesKHR, 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-VkPhysicalDeviceShaderBfloat16FeaturesKHR-sType-sType
    sType must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_BFLOAT16_FEATURES_KHR
