💖 wx_ptp_overflow_check(9) 💖

okay so bestie, welcome to the kernel API manual — this one lives in wx_ptp_overflow_check(9) and honestly? it's a little watchdog with main character energy. let's get into it 🫶

✨ NAME ✨

wx_ptp_overflow_check — the watchdog task whose whole job is to catch SYSTIME overflow before it sneaks up on you 💅

🌸 SYNOPSIS 🌸

void wx_ptp_overflow_check(struct wx *wx);

🎀 ARGUMENTS 🎀

  • wx — a pointer to the wx struct. that's it, that's the whole vibe ✨

🦋 DESCRIPTION 🦋

so the tea is: this watchdog task periodically reads the timecounter so that we don't just. miss it when the system time registers wrap all the way around 😭 like it's literally there to prevent missing the wrap-around moment, no cap.

for the fastest overflowing hardware out there, this thing needs to be run approximately twice a minute — yes, twice a minute, that's the number, don't @ me 🕐🕑

and because it shouldn't have a large impact, we just go ahead and run it for all hardware, not only the speedy ones. lowkey the safest flex 💪

👑 SEE ALSO 👑

the kernel file for this one lives at ./drivers/net/ethernet/wangxun/libwx/wx_ptp.c — go read it, it's giving source code realness 📂✨

and the whole friend group of related functions:

they all ate, fr fr 🔥

💀 reminder bestie: run it roughly twice a minute for the fastest overflowing hardware, or the wrap-around will simply not be caught. that's not a vibe, that's a requirement.

and that's the page!! 🌈 source/version situation is ./drivers/net/ethernet/wangxun... and the date stamp on this whole masterpiece is October 2026 — mwah, slay, periodt 💜🎀🧚
