ice_ptp_rebuild(9)

🎀 NAME

ok so this is ice_ptp_rebuild(9) straight out of the Kernel API Manual, and honestly? it's giving quiet-but-essential. it does exactly one job, and that job is: initialize PTP hardware clock support after reset ✨. like, the clock got yeeted by a reset and this function is the one that patches it back up. main character energy, no cap 💅

---

🦋 SYNOPSIS

void ice_ptp_rebuild (struct ice_pf *pf , enum ice_reset_req reset_type
);

notice the void bestie — it does the thing and gives you nothing back. confident. mysterious. iconic 🫶

---

💖 ARGUMENTS

• pf — the board private structure. that's your whole personality-holding struct for the board, she carries everything 🎀
• reset_type — the reset type being performed. like, which flavor of reset just happened. the enum tells the story here, not us 🌸
