uint32_tdequeue_timeout_nsrte_event_dequeue_burst() timeout on this device. This value should be in the range of
rte_event_dev_info::min_dequeue_timeout_ns and rte_event_dev_info::max_dequeue_timeout_ns returned by
rte_event_dev_info_get() The value 0 is allowed, in which case, default dequeue timeout used.

int32_tnb_events_limit
In a closedsystem this field is the limit on maximum number of events that can be inflight in the
eventdev at a given time. The limit is required to ensure that the finite space in a closed system is not
exhausted. The value cannot exceed rte_event_dev_info::max_num_events returned by
rte_event_dev_info_get().
This value should be set to -1 for opensystems, that is, those systems returning -1 in
rte_event_dev_info::max_num_events.

uint8_tnb_event_queues
Number of event queues to configure on this device. This value includes any single-link queue-port pairs
to be used. This value cannot exceed rte_event_dev_info::max_event_queues +
rte_event_dev_info::max_single_link_event_port_queue_pairs returned by rte_event_dev_info_get(). The
number of non-single-link queues i.e. this value less nb_single_link_event_port_queues in this struct,
cannot exceed rte_event_dev_info::max_event_queues
Definition at line 789 of file rte_eventdev.h.
uint8_tnb_event_ports
Number of event ports to configure on this device. This value includes any single-link queue-port pairs
to be used. This value cannot exceed rte_event_dev_info::max_event_ports +
rte_event_dev_info::max_single_link_event_port_queue_pairs returned by rte_event_dev_info_get(). The
number of non-single-link ports i.e. this value less nb_single_link_event_port_queues in this struct,
cannot exceed rte_event_dev_info::max_event_ports
Definition at line 799 of file rte_eventdev.h.
uint32_tnb_event_queue_flows
Max number of flows needed for a single event queue on this device. This value cannot exceed
rte_event_dev_info::max_event_queue_flows returned by rte_event_dev_info_get()
Definition at line 809 of file rte_eventdev.h.
uint32_tnb_event_port_dequeue_depth
Max number of events that can be dequeued at a time from an event port on this device. This value cannot
exceed rte_event_dev_info::max_event_port_dequeue_depth returned by rte_event_dev_info_get(). Ignored
when device is not RTE_EVENT_DEV_CAP_BURST_MODE capable.

uint32_tnb_event_port_enqueue_depth
Maximum number of events can be enqueued at a time to an event port on this device. This value cannot
exceed rte_event_dev_info::max_event_port_enqueue_depth returned by rte_event_dev_info_get(). Ignored
when device is not RTE_EVENT_DEV_CAP_BURST_MODE capable.

uint8_tnb_single_link_event_port_queues
Number of event ports and queues that will be singly-linked to each other. These are a subset of the
overall event ports and queues; this value cannot exceed nb_event_ports or nb_event_queues. If the device
has ports and queues that are optimized for single-link usage, this field is a hint for how many to
allocate; otherwise, regular event ports and queues will be used.

enumrte_event_dev_preschedule_typepreschedule_type
Event pre-schedule type to use across the event device, if supported.
