Field Documentation

uint32_t dequeue_timeout_ns

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()

RTE_EVENT_DEV_CFG_PER_DEQUEUE_TIMEOUT

Definition at line 408 of file rte_eventdev.h.

int32_t nb_events_limit

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.

Definition at line 415 of file rte_eventdev.h.

uint8_t nb_event_queues

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()

Definition at line 423 of file rte_eventdev.h.

uint8_t nb_event_ports

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()

Definition at line 428 of file rte_eventdev.h.

uint32_t nb_event_queue_flows

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 433 of file rte_eventdev.h.

uint32_t nb_event_port_dequeue_depth

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()

See Also

rte_event_port_setup()

Definition at line 438 of file rte_eventdev.h.

uint32_t nb_event_port_enqueue_depth

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()

rte_event_port_setup()

Definition at line 445 of file rte_eventdev.h.

uint32_t event_dev_cfg

Event device config flags(RTE_EVENT_DEV_CFG_)

Definition at line 452 of file rte_eventdev.h.
