## Name

VkPhysicalDeviceShaderMixedFloatDotProductFeaturesVALVE - Structure describing support for mixed float dot products

Loading… please wait.

## 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)

- VUID-VkPhysicalDeviceShaderMixedFloatDotProductFeaturesVALVE-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_MIXED_FLOAT_DOT_PRODUCT_FEATURES_VALVE

Structure Chaining

Extends the structures

  - VkDeviceCreateInfo

  - VkPhysicalDeviceFeatures2
