VkPhysicalDeviceShaderAtomicInt64Features(3)

# VkPhysicalDeviceShaderAtomicInt64Features(3) Manual Page

## Name

VkPhysicalDeviceShaderAtomicInt64Features - Structure describing features supported by VK_KHR_shader_atomic_int64

## C Specification

The VkPhysicalDeviceShaderAtomicInt64Features structure is defined as:

    // Provided by VK_VERSION_1_2
    typedef struct VkPhysicalDeviceShaderAtomicInt64Features {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           shaderBufferInt64Atomics;
        VkBool32           shaderSharedInt64Atomics;
    } VkPhysicalDeviceShaderAtomicInt64Features;

    // Provided by VK_KHR_shader_atomic_int64
    // Equivalent to VkPhysicalDeviceShaderAtomicInt64Features
    typedef VkPhysicalDeviceShaderAtomicInt64Features VkPhysicalDeviceShaderAtomicInt64FeaturesKHR;

## 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

- `shaderBufferInt64Atomics` indicates whether shaders can perform 64-bit unsigned and signed integer atomic operations on buffers.

- `shaderSharedInt64Atomics` indicates whether shaders can perform 64-bit unsigned and signed integer atomic operations on shared and payload memory.

If the `VkPhysicalDeviceShaderAtomicInt64Features` 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 `VkPhysicalDeviceShaderAtomicInt64Features`, 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-VkPhysicalDeviceShaderAtomicInt64Features-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_ATOMIC_INT64_FEATURES

Structure Chaining
