Definition at line 365 of file rte_eventdev.h.

uint32_t max_event_queue_flows

Maximum supported flows in an event queue by this device

Examples:

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 367 of file rte_eventdev.h.

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 369 of file rte_eventdev.h.

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 373 of file rte_eventdev.h.

uint8_t max_event_ports

Maximum number of event ports supported by this device

Examples:

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 377 of file rte_eventdev.h.

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 379 of file rte_eventdev.h.

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.

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 384 of file rte_eventdev.h.

uint8_t max_event_port_links

Maximum number of queues that can be linked to a single event port by this device.

Definition at line 389 of file rte_eventdev.h.

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 393 of file rte_eventdev.h.

uint32_t event_dev_cap

Event device capabilities(RTE_EVENT_DEV_CAP_)

Examples:

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 398 of file rte_eventdev.h.

uint8_t max_single_link_event_port_queue_pairs

Maximum number of event ports and queues that are optimized for (and only capable of) single-link configurations supported by this device. These ports and queues are not accounted for in max_event_ports or max_event_queues.
