ice_start_phy_timer_eth56g(9)

📦 version 7.3.1, in nixpkgs unstable

💅 ice_start_phy_timer_eth56g — from the Kernel API Manual, bestie ✨

Okay so picture this: it's the Kernel API Manual, it's October 2026, and we're cracking open ice_start_phy_timer_eth56g(9) — yes the whole entire function name, she's long, she's iconic, she's giving "I was named by a committee and I ate". Sit down, hydrate, let's go 🫶

🌸 NAME 🌸

ice_start_phy_timer_eth56g — no cap, her whole job is Start the PHY clock timer. That's it. That's the tweet. 💅

✨ SYNOPSIS ✨

int ice_start_phy_timer_eth56g (struct ice_hw *hw , u8 port );

Look at her. Two arguments, one int return, absolutely zero notes. 🔥

🎀 ARGUMENTS 🎀

  • hw — a pointer to the HW struct. You know the one. The big one. She's holding everything, she's the main character of this whole subsystem tbh 👑
  • port — the PHY port to start. Like, your port. The one you picked. Go off 🦋

💖 DESCRIPTION 💖

So the tea is: this function starts the clock of a PHY port. That's the whole vibe check.

But listen — the way that this is not optional. You literally have to do this as part of the flow to re-calibrate Tx and Rx timestamping offsets in two very specific situations, bestie:

  • whenever the clock time is initialized, and
  • when the link speed changes.

So like… init the clock? Start the timer. Link speed suddenly different? Start the timer. She's the girl you call. Periodt. ⭐

ngl if you skip this step the timestamp offsets are going to be looking real uncalibrated 😭 do not do that to yourself.

🌈 RETURN 🌈

  • 0 — success. slay. we love a zero. 🥳
  • other — the PHY read/write failed. not slay. something in the register-access situation went sideways 💀

🦋 SEE ALSO 🦋

Okay so there are… a lot of friends in this group chat. Like, an unreasonable number. She knows everyone. She's the social butterfly of ./drivers/net/ethernet/intel/ice/ice_ptp_hw.c (that's the kernel file they all live in, in case you were wondering 🧚).

Take a breath. Here we go:

iykyk. that's the whole extended universe right there 🌟

💫 the cute sign-off 💫

This absolute bop of a page lives in ./drivers/net/ethernet/intel/ice (the rest of the file path is up in SEE ALSO, you already saw it 🧚), it's from the Kernel API Manual, dated October 2026, and it's filed under ice_start_phy_timer_eth56g(9). Go start that timer bestie, the clock is literally ticking 💖🎀🦋
