VkDeviceMemoryReportCallbackDataEXT

The definition of VkDeviceMemoryReportCallbackDataEXT is:

typedef struct VkDeviceMemoryReportCallbackDataEXT {
    VkStructureType sType;
    void* pNext;
    VkDeviceMemoryReportFlagsEXT flags;
    VkDeviceMemoryReportEventTypeEXT type;
    uint64_t memoryObjectId;
    VkDeviceSize size;
    VkObjectType objectType;
    uint64_t objectHandle;
    uint32_t heapIndex;
} VkDeviceMemoryReportCallbackDataEXT;

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• flags is 0 and reserved for future use.
• type is a VkDeviceMemoryReportEventTypeEXT type specifying the type of event reported in this VkDeviceMemoryReportCallbackDataEXT structure.
• memoryObjectId is the unique id for the underlying memory object as described below.
• size is the size of the memory object in bytes. If type is VK_DEVICE_MEMORY_REPORT_EVENT_TYPE_ALLOCATE_EXT, VK_DEVICE_MEMORY_REPORT_EVENT_TYPE_IMPORT_EXT or VK_DEVICE_MEMORY_REPORT_EVENT_TYPE_ALLOCATION_FAILED_EXT, size is a valid VkDeviceSize value. Otherwise, size is undefined:.
• objectType is a VkObjectType value specifying the type of the object associated with this device memory report event. If type is VK_DEVICE_MEMORY_REPORT_EVENT_TYPE_ALLOCATE_EXT, VK_DEVICE_MEMORY_REPORT_EVENT_TYPE_FREE_EXT, VK_DEVICE_MEMORY_REPORT_EVENT_TYPE_IMPORT_EXT, VK_DEVICE_MEMORY_REPORT_EVENT_TYPE_UNIMPORT_EXT or VK_DEVICE_MEMORY_REPORT_EVENT_TYPE_ALLOCATION_FAILED_EXT, objectType is a valid VkObjectType enum. Otherwise, objectType is undefined:.
• objectHandle is the object this device memory report event is attributed to. If type is VK_DEVICE_MEMORY_REPORT_EVENT_TYPE_ALLOCATE_EXT, VK_DEVICE_MEMORY_REPORT_EVENT_TYPE_FREE_EXT, VK_DEVICE_MEMORY_REPORT_EVENT_TYPE_IMPORT_EXT or VK_DEVICE_MEMORY_REPORT_EVENT_TYPE_UNIMPORT_EXT, objectHandle is a valid Vulkan handle of the type associated with objectType as defined in the VkObjectType and Vulkan Handle Relationship table. Otherwise, objectHandle is undefined:.
• heapIndex describes which memory heap this device memory allocation is made from. If type is VK_DEVICE_MEMORY_REPORT_EVENT_TYPE_ALLOCATE_EXT or VK_DEVICE_MEMORY_REPORT_EVENT_TYPE_ALLOCATION_FAILED_EXT, heapIndex corresponds to one of the valid heaps from the VkPhysicalDeviceMemoryProperties structure. Otherwise, heapIndex is undefined:.

memoryObjectId is used to avoid double-counting on the same memory object.

If an internally-allocated device memory object or a VkDeviceMemorycannot be exported, memoryObjectId must be unique in the VkDevice.

If an internally-allocated device memory object or a VkDeviceMemory supports being exported, memoryObjectId must be unique system wide.

If an internal device memory object or a VkDeviceMemory is backed by an imported external memory object, memoryObjectId must be unique system wide.
