ice_ptp_adjfine(9)

💅 ice_ptp_adjfine — the clock-frequency glow-up, aka ice_ptp_adjfine(9)

okay so this is from the Kernel API Manual and it's literally the function that gives your clock its lil makeover. bestie, it's giving "fine-tuning era" ✨

---

🌸 NAME

ice_ptp_adjfine — Adjust clock increment rate 🕰️

---

🎀 SYNOPSIS

int ice_ptp_adjfine (struct ptp_clock_info *info , long scaled_ppm );

---

🦋 ARGUMENTS

• info — the driver's PTP info structure 👑 (yes, the whole struct, she's the main character here)
• scaled_ppm — parts per million with a 16-bit fractional field 💫 so like, real precise, no cap

---

💖 DESCRIPTION

Adjust the frequency of the clock by the indicated scaled ppm from the base frequency 🎚️✨

That's it, that's the vibe. You hand her a scaled_ppm, she nudges the clock's frequency that many parts-per-million away from base. tiny adjustments, iconic results 🫶

ngl bestie, that SEE ALSO is a whole friend group 😭 but they're all ice_ptp girlies and they all live in ./drivers/net/ethernet/intel/ice 🧚‍♀️🍓

okay that's the whole page 💜 this one's straight out of ./drivers/net/ethernet/intel/ice, dated October 2026, and yeah — she really said "adjust the increment rate" and meant it. periodt 💅🔥
