VkQueueFamilyGlobalPriorityProperties

Return structure for queue family global priority information query

The VkQueueFamilyGlobalPriorityProperties structure is defined as:

typedef struct VkQueueFamilyGlobalPriorityProperties {
    VkStructureType sType;
    void* pNext;
    uint32_t priorityCount;
    VkQueueGlobalPriority priorities[VK_MAX_GLOBAL_PRIORITY_SIZE];
} VkQueueFamilyGlobalPriorityProperties;

or the equivalent

typedef VkQueueFamilyGlobalPriorityProperties VkQueueFamilyGlobalPriorityPropertiesKHR;

or the equivalent

typedef VkQueueFamilyGlobalPriorityProperties VkQueueFamilyGlobalPriorityPropertiesEXT;
  • sType is a VkStructureType value identifying 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
    VkQueueGlobalPriority enums representing all supported global queue priorities in this queue family. The first priorityCount elements of the array will be valid.

If the VkQueueFamilyGlobalPriorityProperties 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 VkQueueGlobalPriority enums in the ascending order.

For example, returning priorityCount as 3 with supported priorities as VK_QUEUE_GLOBAL_PRIORITY_LOW, VK_QUEUE_GLOBAL_PRIORITY_MEDIUM and VK_QUEUE_GLOBAL_PRIORITY_REALTIME is not allowed.

Valid Usage (Implicit)

VUID-VkQueueFamilyGlobalPriorityProperties-sType-sType

sType must be VK_STRUCTURE_TYPE_QUEUE_FAMILY_GLOBAL_PRIORITY_PROPERTIES
