Field Documentation

const char* driver_name

Event driver name

Definition at line 406 of file rte_eventdev.h.

struct rte_device* dev

Device information

Definition at line 407 of file rte_eventdev.h.

uint32_t min_dequeue_timeout_ns

Minimum supported global dequeue timeout(ns) by this device

Definition at line 408 of file rte_eventdev.h.

uint32_t max_dequeue_timeout_ns

Maximum supported global dequeue timeout(ns) by this device

Definition at line 410 of file rte_eventdev.h.

uint32_t dequeue_timeout_ns

Configured global dequeue timeout(ns) for this device

Definition at line 412 of file rte_eventdev.h.

uint8_t max_event_queues

Maximum event_queues supported by this device

Definition at line 414 of file rte_eventdev.h.

uint32_t max_event_queue_flows

Maximum supported flows in an event queue by this device

Definition at line 416 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 418 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 422 of file rte_eventdev.h.

uint8_t max_event_ports

Maximum number of event ports supported by this device

Definition at line 426 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 428 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 433 of file rte_eventdev.h.

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

Definition at line 438 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 442 of file rte_eventdev.h.

uint32_t event_dev_cap

Event device capabilities(RTE_EVENT_DEV_CAP_)

Definition at line 447 of file rte_eventdev.h.

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.

Definition at line 449 of file rte_eventdev.h.

uint8_t max_profiles_per_port

Maximum number of event queue profiles per event port. A device that doesn't support multiple profiles will set this as 1.

Definition at line 455 of file rte_eventdev.h.
