C Specification

// Provided by VK_KHR_global_priority
typedef struct VkQueueFamilyGlobalPriorityPropertiesKHR {
    VkStructureType             sType;
    void*                       pNext;
    uint32_t                    priorityCount;
    VkQueueGlobalPriorityKHR    priorities[VK_MAX_GLOBAL_PRIORITY_SIZE_KHR];
} VkQueueFamilyGlobalPriorityPropertiesKHR;

or the equivalent

// Provided by VK_EXT_global_priority_query
typedef VkQueueFamilyGlobalPriorityPropertiesKHR VkQueueFamilyGlobalPriorityPropertiesEXT;


  • sType is the type of this structure.

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

  • priorityCount is the number of supported global queue priorities in this queue family, and it must be greater than 0.

  • priorities is an array of VK_MAX_GLOBAL_PRIORITY_SIZE_EXT VkQueueGlobalPriorityEXT enums representing all supported global queue priorities in this queue family. The first priorityCount elements of the array will be valid.


If the VkQueueFamilyGlobalPriorityPropertiesKHR structure is included in the pNext chain of the VkQueueFamilyProperties2 structure passed to vkGetPhysicalDeviceQueueFamilyProperties2, it is filled in with the list of supported global queue priorities for the indicated family.

The valid elements of priorities must not contain any duplicate values.

The valid elements of priorities must be a continuous sequence of VkQueueGlobalPriorityKHR enums in the ascending order.


For example, returning priorityCount as 3 with supported priorities as VK_QUEUE_GLOBAL_PRIORITY_LOW_KHR, VK_QUEUE_GLOBAL_PRIORITY_MEDIUM_KHR and VK_QUEUE_GLOBAL_PRIORITY_REALTIME_KHR is not allowed.

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

  • VUID-VkQueueFamilyGlobalPriorityPropertiesKHR-priorities-parameter
    Any given element of priorities must be a valid VkQueueGlobalPriorityKHR value
