💖 NAME 💖

rte_sched_port_params — the lil' struct that holds every single thing the DPDK scheduler needs to know before it builds you a port. It's literally the vibe-settings sheet for a traffic-managed port, bestie.

✨ SYNOPSIS ✨

#include <rte_sched.h>

🎀 Data Fields 🎀

  • const char * name
  • int socket
  • uint64_t rate
  • uint32_t mtu
  • uint32_t frame_overhead
  • uint32_t n_subports_per_port
  • struct rte_sched_subport_profile_params * subport_profiles
  • uint32_t n_subport_profiles
  • uint32_t n_max_subport_profiles
  • uint32_t n_pipes_per_subport

🦋 DETAILED DESCRIPTION 🦋

Okay so. Port configuration parameters. That's the whole job. That's what this struct is for, and it is serving it.

Defined at line 270 of the file rte_sched.h. ✨

👑 FIELD DOCUMENTATION 👑

const char* name

The name of the port you're associating this config with. Like a little nametag for your port. 🏷️

Defined at line 272 of the file rte_sched.h.

int socket

The CPU socket ID. Gotta tell it where the silicon lives, bestie. 💅

Defined at line 275 of the file rte_sched.h.

uint64_t rate

The output port rate — and this one is measured in bytes per second, no cap. 📈

Defined at line 278 of the file rte_sched.h.

uint32_t mtu

The maximum Ethernet frame size, measured in bytes. Heads up: this should not include the framing overhead. Do not sneak the overhead in there. It's giving separate-concerns. 🙈

Defined at line 283 of the file rte_sched.h.

uint32_t frame_overhead

The framing overhead per packet, measured in bytes. This is where the overhead goes. (See above. We said it separately for a reason.) 🎀

Defined at line 286 of the file rte_sched.h.

uint32_t n_subports_per_port

Number of subports. Just the count. Slay. 🌸

Defined at line 289 of the file rte_sched.h.

struct rte_sched_subport_profile_params* subport_profiles

The subport profile table. Every single pipe gets configured using one of the profiles from this table — that's the whole system, every pipe pulls its fit from this closet. 👗

Defined at line 294 of the file rte_sched.h.

uint32_t n_subport_profiles

The number of profiles in the pipe profile table. 📋

Defined at line 297 of the file rte_sched.h.

uint32_t n_max_subport_profiles

The max allowed profiles in the pipe profile table. The ceiling. The limit. Don't exceed it. 🚫

Defined at line 300 of the file rte_sched.h.

uint32_t n_pipes_per_subport

The maximum number of subport pipes. And the way this one works: it's used to reserve a fixed number of bits in struct rte_mbuf::sched.queue_id for the pipe_id, and that applies to all the subports of the same port. So it's a shared bit-budget situation. 🧮

Defined at line 307 of the file rte_sched.h.
