_ish_sync_fw_clock(9)

✨ _ish_sync_fw_clock — Kernel API Manual ✨

Okay so bestie, welcome to _ish_sync_fw_clock(9) — yes that leading underscore is real and yes it's part of the name, don't @ me 💅. This is the kernel API manual page for it, and we're gonna get you comfy with it in like two minutes flat 🫶.

---

🌸 NAME 🌸

_ish_sync_fw_clock — literally syncs the FW clock with the OS clock. That's the whole vibe. ⏰✨

---

🦋 SYNOPSIS 🦋

void _ish_sync_fw_clock (struct ishtp_device *dev );

It returns void, so like… nothing comes back. It just does the thing 🔥.

---

🎀 ARGUMENTS 🎀

• dev — the ishtp device pointer 👑. That's your one (1) input, bestie. That's it. That's the whole guest list.

---

💖 DESCRIPTION 💖

Okay so what does it actually do? It syncs FW and OS time. Yeah. That's genuinely the entire description in the original and I refuse to invent lore that isn't there 🙈. It's giving "short and iconic", it's giving "said what she said", periodt ✨.

Ngl this is one of those "the name says everything" situations — no cap, no secret extra behaviour to memorise here 💀.

But do keep in mind: the docs list void as the return type, so don't go looking for a status code, there isn't one to check 🧚.

And that's the page, bestie 🎀 — brought to you by the source over in ./drivers/hid/intel-ish-hid/ipc, dated October 2026, and yes the footer really does just say _ish_sync_fw_clock(9) again because the manual page loves a callback 💅✨. Mwah, go sync some clocks 🫶
