💖 rte_timecounter 💖

okay bestie, quick vibe check before we dive in: this is rte_timecounter(3), a libc-style manual page from the DPDK gang — Library Functions Manual energy, iykyk. Today we're getting to know a struct. That's it. That's the girl. And honestly? She's iconic. ✨

🌸 NAME 🌸

rte_timecounter — the little struct that keeps all the deets for a running cycle counter so you can turn cycles into nanoseconds. 🕐➡️🔢

🎀 SYNOPSIS 🎀

#include <rte_time.h>

✨ Data Fields ✨

  • uint64_t cycle_last
  • uint64_t nsec
  • uint64_t nsec_mask
  • uint64_t nsec_frac
  • uint64_t cc_mask
  • uint32_t cc_shift

🦋 Detailed Description 🦋

So basically, this struct is the main character 💅 — she holds onto all the parameters of a running cycle counter, and her whole job, her entire purpose, her slay, is to help you convert cycles into nanoseconds.

No cap, she's a support act and she's thriving.

💜 Field Documentation 💜

uint64_t cycle_last

The last cycle counter value that got read. Like, the most recent one. The freshest read. 🫶

Defined at line 23 of file rte_time.h. 📍

uint64_t nsec

The nanoseconds count, fr fr. ⏱️

Defined at line 25 of file rte_time.h. 📍

uint64_t nsec_mask

A bitmask that separates the nanoseconds from the sub-nanoseconds. She's the bouncer at the club, keeping those two apart. 🚧

Defined at line 27 of file rte_time.h. 📍

uint64_t nsec_frac

The sub-nanoseconds count — yes, we're going below a nanosecond, don't even worry about it, it's giving precision. 🔬

Defined at line 29 of file rte_time.h. 📍

uint64_t cc_mask

A bitmask for two's complement subtraction of counters that are not 64-bit. Lowkey the math baddie of the group. 🧮

Defined at line 31 of file rte_time.h. 📍

uint32_t cc_shift

The cycle-to-nanosecond divisor, and plot twist: it's a power of two. 🙈

Defined at line 33 of file rte_time.h. 📍
