VkQueueGlobalPriority

Possible values of VkDeviceQueueGlobalPriorityCreateInfo::globalPriority, specifying a system-wide priority level are:

typedef enum VkQueueGlobalPriority {
    VK_QUEUE_GLOBAL_PRIORITY_LOW = 128,
    VK_QUEUE_GLOBAL_PRIORITY_MEDIUM = 256,
    VK_QUEUE_GLOBAL_PRIORITY_HIGH = 512,
    VK_QUEUE_GLOBAL_PRIORITY_REALTIME = 1024,
} VkQueueGlobalPriority;

or the equivalent

#define VkQueueGlobalPriorityKHR VkQueueGlobalPriority

or the equivalent

#define VkQueueGlobalPriorityEXT VkQueueGlobalPriority

Priority values are sorted in ascending order. A comparison operation on the enum values can be used to determine the priority order.

• VK_QUEUE_GLOBAL_PRIORITY_LOW is below the system default. Useful for non-interactive tasks.
• VK_QUEUE_GLOBAL_PRIORITY_MEDIUM is the system default priority.
• VK_QUEUE_GLOBAL_PRIORITY_HIGH is above the system default.
• VK_QUEUE_GLOBAL_PRIORITY_REALTIME is the highest priority. Useful for critical tasks.
