C Specification

The VkPhysicalDeviceShaderOCPMicroscalingTypesFeaturesEXT structure is defined as:

// Provided by VK_EXT_shader_ocp_microscaling_types
typedef struct VkPhysicalDeviceShaderOCPMicroscalingTypesFeaturesEXT {
    VkStructureType    sType;
    void*              pNext;
    VkBool32           shaderFloat4;
    VkBool32           shaderFloat6;
    VkBool32           shaderFloat8UnsignedE8M0;
    VkBool32           shaderMXInt8;
} VkPhysicalDeviceShaderOCPMicroscalingTypesFeaturesEXT;

Members

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.

  • shaderFloat4 indicates whether the implementation supports shaders with the Float4EXT or BitcastExtractEXT capabilities.

  • shaderFloat6 indicates whether the implementation supports shaders with the Float6EXT or BitcastExtractEXT capabilities.

  • shaderFloat8UnsignedE8M0 indicates whether the implementation supports shaders with the Float8UnsignedE8M0EXT capability.

  • shaderMXInt8 indicates whether the implementation supports shaders with the MXInt8EXT capability.

Description

If the VkPhysicalDeviceShaderOCPMicroscalingTypesFeaturesEXT 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 VkPhysicalDeviceShaderOCPMicroscalingTypesFeaturesEXT, 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.
