C Specification

Queues can be created with a system-wide priority by adding a VkDeviceQueueGlobalPriorityCreateInfoKHR structure to the pNext chain of VkDeviceQueueCreateInfo.

The VkDeviceQueueGlobalPriorityCreateInfoKHR structure is defined as:

typedef struct VkDeviceQueueGlobalPriorityCreateInfoKHR {
    VkStructureType             sType;
    const void*                 pNext;
    VkQueueGlobalPriorityKHR    globalPriority;
} VkDeviceQueueGlobalPriorityCreateInfoKHR;

or the equivalent

// Provided by VK_EXT_global_priority
typedef VkDeviceQueueGlobalPriorityCreateInfoKHR VkDeviceQueueGlobalPriorityCreateInfoEXT;


  • sType is a VkStructureType value identifying this structure.

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

  • globalPriority is the system-wide priority associated to these queues as specified by VkQueueGlobalPriorityEXT


Queues created without specifying VkDeviceQueueGlobalPriorityCreateInfoKHR will default to VK_QUEUE_GLOBAL_PRIORITY_MEDIUM_KHR.

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

  • VUID-VkDeviceQueueGlobalPriorityCreateInfoKHR-globalPriority-parameter
    globalPriority must be a valid VkQueueGlobalPriorityKHR value
