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 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().

Definition at line 540 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 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().

uint32_t event_queue_cfg

Queue cfg flags(EVENT_QUEUE_CFG_)

Examples:

examples/eventdev_pipeline/pipeline_worker_tx.c.

Definition at line 562 of file rte_eventdev.h.

uint8_t schedule_type

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

Examples:

examples/eventdev_pipeline/pipeline_worker_generic.c, and examples/eventdev_pipeline/pipeline_worker_tx.c.

Definition at line 564 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

Examples:

examples/eventdev_pipeline/pipeline_worker_generic.c, and examples/eventdev_pipeline/pipeline_worker_tx.c.
