💅 fec_ptp_init(9) — Kernel API Manual

okay bestie, so this is a kernel API manual page for fec_ptp_init, and we're gonna get you fluent in it in like two minutes. no cap. 🦋

✨ NAME ✨

fec_ptp_init —

and honestly? that's it. that's the whole NAME line. the description after the dash is literally empty, so we're all just out here raw-dogging it with a function name and vibes 😭 the manpage said "figure it out" and left. iconic of it, honestly.

🌸 SYNOPSIS 🌸

void fec_ptp_init (struct platform_device *pdev , int irq_idx );

so she's void (returns nothing, gives no gifts, just does the work 💅) and she takes exactly two things: a struct platform_device * named pdev, and an int named irq_idx. periodt.

🎀 ARGUMENTS 🎀

  • pdev — the FEC network adapter. this is your main character 🫶 the actual piece of hardware we're doing all this for.
  • irq_idx — the interrupt index. the little number that says which interrupt we're talking about.

🔥 DESCRIPTION 🔥

okay so here's the tea: this function does all the required steps for enabling ptp support. it's the getting-ready-with-me of ptp. 🧚

and here's the plot twist 👑 — if ptp support has already been loaded? she does not redo the whole thing. no ma'am. it simply calls the cyclecounter init routine and exits. in and out, minimal effort, ate and left no crumbs. ⭐

so if you're sitting there like "wait, did it do the full setup or just the cyclecounter thing" — depends on whether ptp support was already loaded. that's the whole vibe check. 💀

💜 SEE ALSO 💜

kernel file ./drivers/net/ethernet/freescale/fec_ptp.c, and the whole friend group:

they're all in ./drivers/net/ethernet/freescale too, iykyk 🌈

and that's the whole page, bestie — short, sweet, and lowkey mysterious. this edition is dated October 2026 and lives under ./drivers/net/ethernet/freescale. go forth and enable ptp responsibly 💖✨🌸
