uint32_t min_dequeue_timeout_ns

Minimum supported global dequeue timeout(ns) by this device

Definition at line 359 of file rte_eventdev.h.

◆ max_dequeue_timeout_ns

uint32_t max_dequeue_timeout_ns

Maximum supported global dequeue timeout(ns) by this device

Definition at line 361 of file rte_eventdev.h.

◆ dequeue_timeout_ns

uint32_t dequeue_timeout_ns

Configured global dequeue timeout(ns) for this device

Definition at line 363 of file rte_eventdev.h.

◆ max_event_queues

uint8_t max_event_queues

◆ max_event_queue_flows

uint32_t max_event_queue_flows

◆ 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 369 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 373 of file rte_eventdev.h.

◆ max_event_ports

uint8_t max_event_ports

◆ max_event_port_dequeue_depth

uint8_t max_event_port_dequeue_depth

◆ max_event_port_enqueue_depth

uint32_t max_event_port_enqueue_depth

◆ max_event_port_links

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.

◆ 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.

◆ event_dev_cap

uint32_t event_dev_cap

◆ max_single_link_event_port_queue_pairs

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.
