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:

Description

  • sType is the type of 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 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. VkPhysicalDeviceShaderAtomicInt64Features can also be used in the pNext chain of VkDeviceCreateInfo to selectively enable these features.

Valid Usage (Implicit)

  • VUID-VkPhysicalDeviceShaderAtomicInt64Features-sType-sType
    sType must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_ATOMIC_INT64_FEATURES
