C Specification

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

The VkDeviceQueueGlobalPriorityCreateInfo structure is defined as:

// Provided by VK_VERSION_1_4
typedef struct VkDeviceQueueGlobalPriorityCreateInfo {
    VkStructureType          sType;
    const void*              pNext;
    VkQueueGlobalPriority    globalPriority;
} VkDeviceQueueGlobalPriorityCreateInfo;

or the equivalent

// Provided by VK_KHR_global_priority
typedef VkDeviceQueueGlobalPriorityCreateInfo VkDeviceQueueGlobalPriorityCreateInfoKHR;

or the equivalent

// Provided by VK_EXT_global_priority
typedef VkDeviceQueueGlobalPriorityCreateInfo VkDeviceQueueGlobalPriorityCreateInfoEXT;

Members

  • 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 VkQueueGlobalPriority

Description

Queues created without specifying VkDeviceQueueGlobalPriorityCreateInfo will default to VK_QUEUE_GLOBAL_PRIORITY_MEDIUM.

Valid Usage (Implicit)
  • VUID-VkDeviceQueueGlobalPriorityCreateInfo-sType-sType
    sType must be VK_STRUCTURE_TYPE_DEVICE_QUEUE_GLOBAL_PRIORITY_CREATE_INFO

  • VUID-VkDeviceQueueGlobalPriorityCreateInfo-globalPriority-parameter
    globalPriority must be a valid VkQueueGlobalPriority value
