ice_ptp_set_vernier_wl(9)

💖 NAME 💖

okay so bestie, welcome to the Kernel API Manual page for ice_ptp_set_vernier_wl(9) — the function that sets the window length for vernier calibration ✨

Like, that's the whole title. ice_ptp_set_vernier_wl — "Set the window length for vernier calibration". Say it with me. Slay.

---

🦋 SYNOPSIS 🦋

int ice_ptp_set_vernier_wl (struct ice_hw *hw );

yeah. one arg. one int coming back at you. iconic behavior honestly 💅

---

🌸 ARGUMENTS 🌸

• hw — pointer to the HW struct 🫶 that's it, that's the whole input. give it the hardware struct and let it cook.

---

🎀 DESCRIPTION 🎀

So what does it actually do?? It sets the window length used for the vernier port calibration process. that's the entire description and honestly? it ate. no filler, no fluff, no "in some cases" caveats — just a straight-up setter doing setter things 💜

think of it as: calibration needs a window, this function picks the window length. main character energy for a one-line description ngl 👑

⭐ SEE ALSO ⭐

first up, the actual home of this thing — the kernel file it lives in, no cap:

• Kernel file ./drivers/net/ethernet/intel/ice/ice_ptp_hw.c 🍓

and then… okay. buckle up bestie 😭 because the cross-reference list here is long. like, extended-family-holiday-dinner long. every single one of the ice PTP friends shows up, so here's the full roll call, verbatim, exactly as the manual gives it — not me dropping a single name, periodt:

ngl bestie, this one is short and sweet: no flags, no env vars, no exit-status drama, no bug notes, no warnings — just a struct ice_hw * and a window length. sometimes a manpage is just a manpage 💅

---

and that's the page!! mwah 🫶 this lil number came to you from the ./drivers/net/ethernet/intel/ice corner of the source tree, dated October 2026, and it is — as always — the ice_ptp_set_vernier_wl(9) page from the Kernel API Manual. bye bestie, go set some window lengths 💖🎀✨
