Field Documentation uint32_t nb_atomic_flows 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 rte_event_queue_conf::event_queue_cfg or RTE_SCHED_TYPE_ATOMIC flag to rte_event_queue_conf::schedule_type), then the value must be in the range of [1, rte_event_dev_config::nb_event_queue_flows], which was previously provided in rte_event_dev_configure(). If the queue is not configured for atomic scheduling this value is ignored. Definition at line 912 of file rte_eventdev.h. uint32_t nb_atomic_order_sequences The maximum number of outstanding events waiting to be reordered by this queue. In other words, the number of entries in this queues 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 no events 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 rte_event_queue_conf::event_queue_cfg or RTE_SCHED_TYPE_ORDERED flag to rte_event_queue_conf::schedule_type), then the value must be in the range of [1, rte_event_dev_config::nb_event_queue_flows], which was previously supplied to rte_event_dev_configure(). If the queue is not configured for ordered scheduling, then this value is ignored. Definition at line 925 of file rte_eventdev.h. uint32_t event_queue_cfg Queue cfg flags(EVENT_QUEUE_CFG_) Definition at line 943 of file rte_eventdev.h. uint8_t schedule_type Queue schedule type(RTE_SCHED_TYPE_*). Valid when RTE_EVENT_QUEUE_CFG_ALL_TYPES flag is not set in rte_event_queue_conf::event_queue_cfg. If the RTE_EVENT_QUEUE_CFG_ALL_TYPES flag is set, then this field is ignored. See also RTE_SCHED_TYPE_ORDERED, RTE_SCHED_TYPE_ATOMIC, RTE_SCHED_TYPE_PARALLEL Definition at line 945 of file rte_eventdev.h. uint8_t priority 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, ignored otherwise Definition at line 955 of file rte_eventdev.h. uint8_t weight Weight of the event queue relative to other event queues. The requested weight should be in the range of [RTE_EVENT_QUEUE_WEIGHT_HIGHEST, RTE_EVENT_QUEUE_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, ignored otherwise. Definition at line 966 of file rte_eventdev.h. uint8_t affinity Affinity of the event queue relative to other event queues. The requested affinity should be in the range of [RTE_EVENT_QUEUE_AFFINITY_HIGHEST, RTE_EVENT_QUEUE_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, ignored otherwise.
