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 911 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 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 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 924 of file rte_eventdev.h.

   uint32_t event_queue_cfg
       Queue cfg flags(EVENT_QUEUE_CFG_)

       Definition at line 942 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.

           RTE_SCHED_TYPE_ORDERED, RTE_SCHED_TYPE_ATOMIC, RTE_SCHED_TYPE_PARALLEL

       Definition at line 944 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 954 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 965 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.
