VkPhysicalDeviceShaderFloat8FeaturesEXT(3)

# VkPhysicalDeviceShaderFloat8FeaturesEXT(3) Manual Page

## Name

VkPhysicalDeviceShaderFloat8FeaturesEXT - Structure describing float8 features that can be supported by the implementation

## C Specification

The `VkPhysicalDeviceShaderFloat8FeaturesEXT` structure is defined as:

    // Provided by VK_EXT_shader_float8
    typedef struct VkPhysicalDeviceShaderFloat8FeaturesEXT {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           shaderFloat8;
        VkBool32           shaderFloat8CooperativeMatrix;
    } VkPhysicalDeviceShaderFloat8FeaturesEXT;

## 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.

- `shaderFloat8` indicates whether the implementation supports shaders with the `Float8EXT` capability.

- `shaderFloat8CooperativeMatrix` indicates whether the implementation supports shaders with the `Float8CooperativeMatrixEXT` capability.

## Description

If the `VkPhysicalDeviceShaderFloat8FeaturesEXT` 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 `VkPhysicalDeviceShaderFloat8FeaturesEXT`, 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-VkPhysicalDeviceShaderFloat8FeaturesEXT-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_FLOAT8_FEATURES_EXT

Structure Chaining

Extends the structures

  - VkDeviceCreateInfo

  - VkPhysicalDeviceFeatures2
