VkPhysicalDeviceShaderIntegerDotProductFeatures(3)

# VkPhysicalDeviceShaderIntegerDotProductFeatures(3) Manual Page

## Name

VkPhysicalDeviceShaderIntegerDotProductFeatures - Structure describing integer dot product features that can be supported by an implementation

## C Specification

The `VkPhysicalDeviceShaderIntegerDotProductFeatures` structure is defined as:

    // Provided by VK_VERSION_1_3
    typedef struct VkPhysicalDeviceShaderIntegerDotProductFeatures {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           shaderIntegerDotProduct;
    } VkPhysicalDeviceShaderIntegerDotProductFeatures;

    // Provided by VK_KHR_shader_integer_dot_product
    // Equivalent to VkPhysicalDeviceShaderIntegerDotProductFeatures
    typedef VkPhysicalDeviceShaderIntegerDotProductFeatures VkPhysicalDeviceShaderIntegerDotProductFeaturesKHR;

## Members

This structure describes the following feature:

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

## Description

- `shaderIntegerDotProduct` specifies whether shader modules can declare the `DotProductInputAllKHR`, `DotProductInput4x8BitKHR`, `DotProductInput4x8BitPackedKHR` and `DotProductKHR` capabilities.

If the `VkPhysicalDeviceShaderIntegerDotProductFeatures` 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 `VkPhysicalDeviceShaderIntegerDotProductFeatures`, 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-VkPhysicalDeviceShaderIntegerDotProductFeatures-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_INTEGER_DOT_PRODUCT_FEATURES

Structure Chaining

Extends the structures

  - VkDeviceCreateInfo

  - VkPhysicalDeviceFeatures2
