C Specification

To query 64-bit atomic support for signed and unsigned integers with images call vkGetPhysicalDeviceFeatures2 with a VkPhysicalDeviceShaderImageAtomicInt64FeaturesEXT structure included in the pNext chain of its pFeatures parameter.

// Provided by VK_EXT_shader_image_atomic_int64
typedef struct VkPhysicalDeviceShaderImageAtomicInt64FeaturesEXT {
    VkStructureType    sType;
    void*              pNext;
    VkBool32           shaderImageInt64Atomics;
    VkBool32           sparseImageInt64Atomics;
} VkPhysicalDeviceShaderImageAtomicInt64FeaturesEXT;


  • sType is the type of this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • shaderImageInt64Atomics indicates whether shaders can support 64-bit unsigned and signed integer atomic operations on images.

  • sparseImageInt64Atomics indicates whether 64-bit integer atomics can be used on sparse images.


Valid Usage (Implicit)
  • VUID-VkPhysicalDeviceShaderImageAtomicInt64FeaturesEXT-sType-sType
