rte_event_dequeue_burst() timeout on this device. This value should be in the range of min_dequeue_timeout_ns and max_dequeue_timeout_ns which previously provided in rte_event_dev_info_get() The value 0 is allowed, in which case, default dequeue timeout used.

In a closed system 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 overwhelmed. The value cannot exceed the max_num_events as provided by rte_event_dev_info_get(). This value should be set to -1 for open system.

Number of event queues to configure on this device. This value cannot exceed the max_event_queues which previously provided in rte_event_dev_info_get()

Number of event ports to configure on this device. This value cannot exceed the max_event_ports which previously provided in rte_event_dev_info_get()

Number of flows for any event queue on this device. This value cannot exceed the max_event_queue_flows which previously provided in rte_event_dev_info_get()

Definition at line 542 of file rte_eventdev.h.

Maximum number of events can be dequeued at a time from an event port by this device. This value cannot exceed the max_event_port_dequeue_depth which previously provided in rte_event_dev_info_get(). Ignored when device is not RTE_EVENT_DEV_CAP_BURST_MODE capable.

Maximum number of events can be enqueued at a time from an event port by this device. This value cannot exceed the max_event_port_enqueue_depth which previously provided in rte_event_dev_info_get(). Ignored when device is not RTE_EVENT_DEV_CAP_BURST_MODE capable.

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 can be used.
