# VkPhysicalDeviceShaderAtomicFloat16VectorFeaturesNV(3) Manual Page

## Name

VkPhysicalDeviceShaderAtomicFloat16VectorFeaturesNV - Structure describing features supported by VK_NV_shader_atomic_float16_vector

Loading… please wait.

## C Specification

The VkPhysicalDeviceShaderAtomicFloat16VectorFeaturesNV structure is defined as:

    // Provided by VK_NV_shader_atomic_float16_vector
    typedef struct VkPhysicalDeviceShaderAtomicFloat16VectorFeaturesNV {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           shaderFloat16VectorAtomics;
    } VkPhysicalDeviceShaderAtomicFloat16VectorFeaturesNV;

## 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.

## Description

- `shaderFloat16VectorAtomics` indicates whether shaders can perform 16-bit floating-point, 2- and 4-component vector atomic operations.

If the `VkPhysicalDeviceShaderAtomicFloat16VectorFeaturesNV` 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 `VkPhysicalDeviceShaderAtomicFloat16VectorFeaturesNV`, 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-VkPhysicalDeviceShaderAtomicFloat16VectorFeaturesNV-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_ATOMIC_FLOAT16_VECTOR_FEATURES_NV

Structure Chaining

Extends the structures

  - VkDeviceCreateInfo

  - VkPhysicalDeviceFeatures2
