C Specification

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

// Provided by VK_EXT_global_priority
typedef enum VkQueueGlobalPriorityEXT {
    VK_QUEUE_GLOBAL_PRIORITY_LOW_EXT = 128,
    VK_QUEUE_GLOBAL_PRIORITY_MEDIUM_EXT = 256,
    VK_QUEUE_GLOBAL_PRIORITY_HIGH_EXT = 512,
    VK_QUEUE_GLOBAL_PRIORITY_REALTIME_EXT = 1024,
} VkQueueGlobalPriorityEXT;

Description

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_EXT is below the system default. Useful for non-interactive tasks.

  • VK_QUEUE_GLOBAL_PRIORITY_MEDIUM_EXT is the system default priority.

  • VK_QUEUE_GLOBAL_PRIORITY_HIGH_EXT is above the system default.

  • VK_QUEUE_GLOBAL_PRIORITY_REALTIME_EXT is the highest priority. Useful for critical tasks.
