💅 ice_ptp_port_phy_restart(9) — bestie's guide to the Kernel API Manual

okay so picture this: you're deep in the Kernel API Manual, you found a PHY that needs its timestamping situation sorted, and you open this page. slay, you're in the right place. this is ice_ptp_port_phy_restart, and she's the one who kicks the PHY timestamping block into gear. 🎀

✨ SYNOPSIS ✨

int ice_ptp_port_phy_restart (struct ice_ptp_port *ptp_port );

it returns an int, she takes one arg, and honestly? iconic behaviour. 💅

🌸 ARGUMENTS 🌸

  • ptp_port — the PTP port whose PHY start is set. that's it, that's the whole vibe. she hands you the port, you hand her the port. 🫶

💖 DESCRIPTION 💖

so what actually happens?? two things, bestie, and they're both important. ✨

first: she starts the PHY timestamping block. the block goes from "not it" to "it." 🔥

second: she kicks off Vernier timestamping calibration. yes, Vernier, like the fancy measurement thing. she's calibrating. let her cook. 👑

and here's the lowkey important part — the vibe check. if the timestamping block can't be calibrated (for example, if the link is down), she doesn't just leave it hanging half-alive like some kind of chaos gremlin. instead she disables the timestamping block. no half-finished situationships here. it's either calibrated or it's off. periodt. 💀

ngl, "link is down" is the example the page gives for why calibration might fail — so if things look off, check your link first, bestie. 🙈

🦋 SEE ALSO 🦋

literally the whole ice_ptp extended universe, and we are obsessed. also, the source lives in the kernel file ./drivers/net/ethernet/intel/ice/ice_ptp.c — go say hi. 💜

🌈 and that's the whole page!! no cap, she's short but she's got range. this lil beauty lives in ./drivers/net/ethernet/intel/ice, straight from October 2026, and the manpage itself is ice_ptp_port_phy_restart(9) from the Kernel API Manual. mwah 💋 go calibrate something, bestie. 🧚‍♀️💖
