✨ NAME ✨

rte_event_port_conf — it's giving event port configuration struct, bestie 💅

(this one lives in the rte_event_port_conf(3) page under Library Functions Manual, iykyk)

🌸 SYNOPSIS 🌸

#include <rte_eventdev.h>

🎀 Data Fields

  • int32_t new_event_threshold
  • uint16_t dequeue_depth
  • uint16_t enqueue_depth
  • uint32_t event_port_cfg

💖 DESCRIPTION 💖

okay so. rte_event_port_conf is the Event port configuration structure. that's the whole vibe. it's the little bundle of settings you hand over when you're setting up an event port 🦋

👑 FIELD DOCUMENTATION 👑

🌟 int32_t new_event_threshold

A backpressure threshold for new event enqueues on this port. use it for a closed system event dev where the event capacity is limited — and it cannot exceed the capacity of the event dev, no cap 🚫

Configuring ports with different thresholds can make higher priority traffic less likely to be backpressured. for example, a port used to inject NIC Rx packets into the event dev can have a lower threshold so as not to overwhelm the device, while ports used for worker pools can have a higher threshold. this value cannot exceed the nb_events_limit value which was previously supplied to rte_event_dev_configure().

This should be set to '-1' for open system, i.e when max_num_events == -1.

🦋 uint16_t dequeue_depth

Configure the maximum size of burst dequeues for this event port. this value cannot exceed the nb_event_port_dequeue_depth value which was previously supplied to rte_event_dev_configure().

Ignored when device does not support the RTE_EVENT_DEV_CAP_BURST_MODE capability.

🌈 uint16_t enqueue_depth

Configure the maximum size of burst enqueues to this event port. this value cannot exceed the nb_event_port_enqueue_depth value which was previously supplied to rte_event_dev_configure().

Ignored when device does not support the RTE_EVENT_DEV_CAP_BURST_MODE capability.

💜 uint32_t event_port_cfg

Port configuration flags(EVENT_PORT_CFG_) — the little toggles, the main character energy of this struct ✨
