Field Documentation

const char* driver_name

Event driver name

Definition at line 343 of file rte_eventdev.h.

struct rte_device* dev

Device information

Definition at line 344 of file rte_eventdev.h.

uint32_t min_dequeue_timeout_ns

Minimum supported global dequeue timeout(ns) by this device

Definition at line 346 of file rte_eventdev.h.

uint32_t max_dequeue_timeout_ns

Maximum supported global dequeue timeout(ns) by this device

Definition at line 348 of file rte_eventdev.h.

uint32_t dequeue_timeout_ns

Configured global dequeue timeout(ns) for this device

Definition at line 350 of file rte_eventdev.h.

uint8_t max_event_queues

Maximum event_queues supported by this device

Definition at line 352 of file rte_eventdev.h.

uint32_t max_event_queue_flows

Maximum supported flows in an event queue by this device

Definition at line 354 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 356 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 360 of file rte_eventdev.h.

uint8_t max_event_ports

Maximum number of event ports supported by this device

Definition at line 364 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.

Definition at line 366 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.

Definition at line 371 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.

Definition at line 376 of file rte_eventdev.h.

uint32_t event_dev_cap

Event device capabilities(RTE_EVENT_DEV_CAP_)

Definition at line 381 of file rte_eventdev.h.
