Field Documentation

uint32_tnb_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_tnb_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.

uint32_tevent_queue_cfg
Queue cfg flags(EVENT_QUEUE_CFG_)

Definition at line 942 of file rte_eventdev.h.

uint8_tschedule_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.

Definition at line 944 of file rte_eventdev.h.

uint8_tpriority
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_tweight
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_taffinity
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.
