Definition at line 411 of file rte_eventdev.h.

◆ max_event_queue_priority_levels

uint8_t max_event_queue_priority_levels

Maximum number of event queue priority levels by this device. Valid when the device has RTE_EVENT_DEV_CAP_QUEUE_QOS capability

Definition at line 413 of file rte_eventdev.h.

◆ max_event_priority_levels

uint8_t max_event_priority_levels

Maximum number of event priority levels by this device. Valid when the device has RTE_EVENT_DEV_CAP_EVENT_QOS capability

Definition at line 417 of file rte_eventdev.h.

◆ max_event_ports

uint8_t max_event_ports

Maximum number of event ports supported by this device

Definition at line 421 of file rte_eventdev.h.

◆ max_event_port_dequeue_depth

uint8_t max_event_port_dequeue_depth

Maximum number of events can be dequeued at a time from an event port by this device. A device that does not support bulk dequeue will set this as 1.

Examples: examples/ipsec-secgw/event_helper.c, examples/l2fwd-event/l2fwd_event_generic.c, examples/l2fwd-event/l2fwd_event_internal_port.c, examples/l3fwd/l3fwd_event_generic.c, and examples/l3fwd/l3fwd_event_internal_port.c.

Definition at line 423 of file rte_eventdev.h.

◆ max_event_port_enqueue_depth

uint32_t max_event_port_enqueue_depth

Maximum number of events can be enqueued at a time from an event port by this device. A device that does not support bulk enqueue will set this as 1.

Definition at line 433 of file rte_eventdev.h.

◆ max_num_events

int32_t max_num_events

A closed system event dev has a limit on the number of events it can manage at a time. An open system event dev does not have a limit and will specify this as -1.

Examples: examples/ipsec-secgw/event_helper.c, examples/l2fwd-event/l2fwd_event_generic.c, examples/l2fwd-event/l2fwd_event_internal_port.c, examples/l3fwd/l3fwd_event_generic.c, and examples/l3fwd/l3fwd_event_internal_port.c.

Definition at line 437 of file rte_eventdev.h.
