VkPhysicalDeviceShaderAtomicInt64Features(3)

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;

or the equivalent

// Provided by VK_KHR_shader_atomic_int64
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
