--
-- == Description
--
-- This device extension allows applications to query the global queue
-- priorities supported by a queue family. It allows implementations to
-- report which global priority levels are treated differently by the
-- implementation, instead of silently mapping multiple requested global
-- priority levels to the same internal priority, or using device creation
-- failure to signal that a requested priority is not supported. It is
-- intended primarily for use by system integration along with certain
-- platform-specific priority enforcement rules.
--
-- == New Structures
--
-- -   Extending
--     'Vulkan.Core11.Promoted_From_VK_KHR_get_physical_device_properties2.PhysicalDeviceFeatures2',
--     'Vulkan.Core10.Device.DeviceCreateInfo':
--
--     -   'PhysicalDeviceGlobalPriorityQueryFeaturesEXT'
--
-- -   Extending
--     'Vulkan.Core11.Promoted_From_VK_KHR_get_physical_device_properties2.QueueFamilyProperties2':
--
--     -   'QueueFamilyGlobalPriorityPropertiesEXT'
--
-- == New Enum Constants
--
-- -   'EXT_GLOBAL_PRIORITY_QUERY_EXTENSION_NAME'
--
-- -   'EXT_GLOBAL_PRIORITY_QUERY_SPEC_VERSION'
--
-- -   'Vulkan.Core10.APIConstants.MAX_GLOBAL_PRIORITY_SIZE_EXT'
--
-- -   Extending 'Vulkan.Core10.Enums.StructureType.StructureType':
--
--     -   'Vulkan.Core10.Enums.StructureType.STRUCTURE_TYPE_PHYSICAL_DEVICE_GLOBAL_PRIORITY_QUERY_FEATURES_EXT'
--
--     -   'Vulkan.Core10.Enums.StructureType.STRUCTURE_TYPE_QUEUE_FAMILY_GLOBAL_PRIORITY_PROPERTIES_EXT'
--
-- == Issues
--
-- 1) Can we additionally query whether a caller is permitted to acquire a
-- specific global queue priority in this extension?
--
-- __RESOLVED__: No. Whether a caller has enough privilege goes with the
-- OS, and the Vulkan driver cannot really guarantee that the privilege
-- will not change in between this query and the actual queue creation
-- call.
--
-- 2) If more than 1 queue using global priority is requested, is there a
-- good way to know which queue is failing the device creation?
--
-- __RESOLVED__: No. There is not a good way at this moment, and it is also
-- not quite actionable for the applications to know that because the
-- information may not be accurate. Queue creation can fail because of
-- runtime constraints like insufficient privilege or lack of resource, and
-- the failure is not necessarily tied to that particular queue
-- configuration requested.
