uint32_t dequeue_timeout_ns¶

rte_event_dequeue_burst() timeout on this device. This value should be in the range of rte_event_dev_info::min_dequeue_timeout_ns and rte_event_dev_info::max_dequeue_timeout_ns returned by rte_event_dev_info_get() The value 0 is allowed, in which case, default dequeue timeout used.

int32_t nb_events_limit¶

In a closed system this field is the limit on maximum number of events that can be inflight in the eventdev at a given time. The limit is required to ensure that the finite space in a closed system is not exhausted. The value cannot exceed rte_event_dev_info::max_num_events returned by rte_event_dev_info_get().

This value should be set to -1 for open systems, that is, those systems returning -1 in rte_event_dev_info::max_num_events.

uint8_t nb_event_queues¶

Number of event queues to configure on this device. This value includes any single-link queue-port pairs to be used. This value cannot exceed rte_event_dev_info::max_event_queues + rte_event_dev_info::max_single_link_event_port_queue_pairs returned by rte_event_dev_info_get(). The number of non-single-link queues i.e. this value less nb_single_link_event_port_queues in this struct, cannot exceed rte_event_dev_info::max_event_queues

Definition at line 789 of file rte_eventdev.h.

uint8_t nb_event_ports¶

Number of event ports to configure on this device. This value includes any single-link queue-port pairs to be used. This value cannot exceed rte_event_dev_info::max_event_ports + rte_event_dev_info::max_single_link_event_port_queue_pairs returned by rte_event_dev_info_get(). The number of non-single-link ports i.e. this value less nb_single_link_event_port_queues in this struct, cannot exceed rte_event_dev_info::max_event_ports

Definition at line 799 of file rte_eventdev.h.

uint32_t nb_event_queue_flows¶

Max number of flows needed for a single event queue on this device. This value cannot exceed rte_event_dev_info::max_event_queue_flows returned by rte_event_dev_info_get()

Definition at line 809 of file rte_eventdev.h.

uint32_t nb_event_port_dequeue_depth¶

Max number of events that can be dequeued at a time from an event port on this device. This value cannot exceed rte_event_dev_info::max_event_port_dequeue_depth returned by rte_event_dev_info_get(). Ignored when device is not RTE_EVENT_DEV_CAP_BURST_MODE capable.

uint32_t nb_event_port_enqueue_depth¶

Maximum number of events can be enqueued at a time to an event port on this device. This value cannot exceed rte_event_dev_info::max_event_port_enqueue_depth returned by rte_event_dev_info_get(). Ignored when device is not RTE_EVENT_DEV_CAP_BURST_MODE capable.

uint32_t event_dev_cfg¶

Event device config flags(RTE_EVENT_DEV_CFG_)

Definition at line 828 of file rte_eventdev.h.

uint8_t nb_single_link_event_port_queues¶

Number of event ports and queues that will be singly-linked to each other. These are a subset of the overall event ports and queues; this value cannot exceed nb_event_ports or nb_event_queues. If the device has ports and queues that are optimized for single-link usage, this field is a hint for how many to allocate; otherwise, regular event ports and queues will be used.

Definition at line 830 of file rte_eventdev.h.

enum rte_event_dev_preschedule_type preschedule_type¶

Event pre-schedule type to use across the event device, if supported.
