🌸 idpf_ptp_create_clock — Kernel API Manual 🌸

okay so bestie, welcome to the idpf_ptp_create_clock(9) page 💅 this one lives in the 9 section of the Kernel API Manual, and it's short, sweet, and kind of a big deal if you're into precision time stuff ✨

✨ NAME ✨

idpf_ptp_create_clock — literally just creating a PTP clock device for userspace 🕰️👑

🦋 SYNOPSIS 🦋

int idpf_ptp_create_clock (const struct idpf_adapter *adapter );

that's the whole signature, no cap 🫶

🎀 ARGUMENTS 🎀

  • adapter — the driver-specific private structure 🌸 this is your lil bundle of everything the driver knows about itself, and you're handing it over so the function can do its thing.

💖 DESCRIPTION 💖

so what does it do?? this function creates a new PTP clock device 🕰️✨ that's it, that's the plot. it's giving "make the clock, hand it to userspace, slay." the way that a PTP clock device gets born right here and userspace gets to see it — iconic behavior honestly 👑

🔥 RETURN 🔥

  • 0 on success 🎉
  • -errno otherwise 😭 (so like, a negative errno value — that's your "something went sideways" signal, go check errno bestie)

🌈 SEE ALSO 🌈

okay this list is LONG, grab a snack 🍓 but fr fr these are all the sibling functions in the same little PTP family, and you're gonna want to know them:

and the source file itself, for when you gotta read the real thing 👀:

  • Kernel file ./drivers/net/ethernet/intel/idpf/idpf_ptp.c
pro tip from your girl: man 9 idpf_ptp_init and man 9 idpf_ptp_release are like the bookends of this whole PTP saga — start there if you're lost 🧚

⭐ and that's the page, bestie! this one came out of ./drivers/net/ethernet/intel/idpf, dated October 2026, and it's the idpf_ptp_create_clock(9) entry of the Kernel API Manual — go forth and create clocks 💜🦋💅
