-- == Description
--
-- In Vulkan, users can specify device-scope queue priorities. In some
-- cases it may be useful to extend this concept to a system-wide scope.
-- This extension provides a mechanism for callers to set their system-wide
-- priority. The default queue priority is
-- 'QUEUE_GLOBAL_PRIORITY_MEDIUM_EXT'.
--
-- The driver implementation will attempt to skew hardware resource
-- allocation in favour of the higher-priority task. Therefore,
-- higher-priority work may retain similar latency and throughput
-- characteristics even if the system is congested with lower priority
-- work.
--
-- The global priority level of a queue shall take precedence over the
-- per-process queue priority
-- ('Vulkan.Core10.Device.DeviceQueueCreateInfo'::@pQueuePriorities@).
--
-- Abuse of this feature may result in starving the rest of the system from
-- hardware resources. Therefore, the driver implementation may deny
-- requests to acquire a priority above the default priority
-- ('QUEUE_GLOBAL_PRIORITY_MEDIUM_EXT') if the caller does not have
-- sufficient privileges. In this scenario
-- 'Vulkan.Core10.Enums.Result.ERROR_NOT_PERMITTED_EXT' is returned.
--
-- The driver implementation may fail the queue allocation request if
-- resources required to complete the operation have been exhausted (either
-- by the same process or a different process). In this scenario
-- 'Vulkan.Core10.Enums.Result.ERROR_INITIALIZATION_FAILED' is returned.
