The maximum number of active flows this queue can track at any given time. If the queue is configured for atomic scheduling (by applying the RTE_EVENT_QUEUE_CFG_ALL_TYPES flag to event_queue_cfg or RTE_SCHED_TYPE_ATOMIC flag to schedule_type), then the value must be in the range of [1, nb_event_queue_flows], which was previously provided in rte_event_dev_configure().

The maximum number of outstanding events waiting to be reordered by this queue. In other words, the number of entries in this queue’s reorder buffer.When the number of events in the reorder buffer reaches to nb_atomic_order_sequences then the scheduler cannot schedule the events from this queue and invalid event will be returned from dequeue until one or more entries are freed up/released. If the queue is configured for ordered scheduling (by applying the RTE_EVENT_QUEUE_CFG_ALL_TYPES flag to event_queue_cfg or RTE_SCHED_TYPE_ORDERED flag to schedule_type), then the value must be in the range of [1, nb_event_queue_flows], which was previously supplied to rte_event_dev_configure().

Queue schedule type(RTE_SCHED_TYPE_*). Valid when RTE_EVENT_QUEUE_CFG_ALL_TYPES bit is not set in event_queue_cfg.

Definition at line 639 of file rte_eventdev.h.

Priority for this event queue relative to other event queues. The requested priority should in the range of [RTE_EVENT_DEV_PRIORITY_HIGHEST, RTE_EVENT_DEV_PRIORITY_LOWEST]. The implementation shall normalize the requested priority to event device supported priority value. Valid when the device has RTE_EVENT_DEV_CAP_QUEUE_QOS capability

Definition at line 644 of file rte_eventdev.h.

Weight of the event queue relative to other event queues. The requested weight should be in the range of [RTE_EVENT_DEV_WEIGHT_HIGHEST, RTE_EVENT_DEV_WEIGHT_LOWEST]. The implementation shall normalize the requested weight to event device supported weight value. Valid when the device has RTE_EVENT_DEV_CAP_QUEUE_QOS capability.

Definition at line 652 of file rte_eventdev.h.

Affinity of the event queue relative to other event queues. The requested affinity should be in the range of [RTE_EVENT_DEV_AFFINITY_HIGHEST, RTE_EVENT_DEV_AFFINITY_LOWEST]. The implementation shall normalize the requested affinity to event device supported affinity value. Valid when the device has RTE_EVENT_DEV_CAP_QUEUE_QOS capability.
