VkPhysicalDeviceShaderAtomicInt64Features

The VkPhysicalDeviceShaderAtomicInt64Features structure is defined as:

typedef struct VkPhysicalDeviceShaderAtomicInt64Features {
    VkStructureType sType;
    void* pNext;
    VkBool32 shaderBufferInt64Atomics;
    VkBool32 shaderSharedInt64Atomics;
} VkPhysicalDeviceShaderAtomicInt64Features;

or the equivalent

typedef VkPhysicalDeviceShaderAtomicInt64Features VkPhysicalDeviceShaderAtomicInt64FeaturesKHR;

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.
• 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.
