ice_ptp_init(9)

🌸 ice_ptp_init(9) — straight outta the Kernel API Manual 🌸

okay bestie, buckle up, we're talking about ice_ptp_init today — the kernel API manual page that literally sets up your PTP hardware clock support ✨ this is the group-chat recap, no details lost, i promise 🫶

💅 NAME 💅

ice_ptp_init — initialize PTP hardware clock support 🔥

---

✨ SYNOPSIS ✨

void ice_ptp_init (struct ice_pf *pf );

---

🎀 ARGUMENTS 🎀

• pf — the board private structure, aka the main character of this whole function 💖

---

🦋 DESCRIPTION 🦋

so the vibe here is: this sets up the device so it can interact with the PTP hardware clock, and it does that for all the functions — both the function that actually owns the clock hardware 👑 and the functions that are connected to the clock hardware 🔗. everyone gets an invite to the party, bestie.

the clock owner is the one that allocates and registers a ptp_clock with the PTP_1588_CLOCK infrastructure ⭐. and then — this part is lowkey important — all functions allocate a kthread and work items, which are used for asynchronous work, things like Tx timestamps and periodic work 😭 they really said "everybody works, nobody coasts."

no cap, that's the whole function. short, sweet, and it's giving infrastructure. 🧚

this cutie came to you straight from ./drivers/net/ethernet/intel/ice, dated October 2026, and it lives in the Kernel API Manual 🎀 slay, bye 💜
