wx_ptp_tx_hwtstamp_work(9)

💅 wx_ptp_tx_hwtstamp_work(9) — the Kernel API Manual glow-up 🎀

okay bestie, so this is a page from the Kernel API Manual (kernel docs section 9, driver/kernel API vibes ✨) and it's all about wx_ptp_tx_hwtstamp_work — literally the little worker that checks whether a Tx time stamp is still pending. no cap, it's giving "did the hardware finish yet" energy 🔥

---

✨ NAME ✨

wx_ptp_tx_hwtstamp_work — check for a pending Tx time stamp 🕐

🦋 SYNOPSIS 🦋

int wx_ptp_tx_hwtstamp_work (struct wx *wx );

🌸 ARGUMENTS 🌸

• wx — the private board struct 🫶 like, the board's own little private stash of info, iykyk

💖 DESCRIPTION 💖

okay so here's the whole vibe 👑: if a Tx timestamp request is outstanding and the hardware has latched a valid value, we convert it into the timecounter ns value, then store that result into the shhwtstamps structure — which is passed up the network stack 📤✨. that's literally it, that's the whole job. main character energy fr fr.

like, imagine the hardware being like "bestie I got a timestamp for u 💅" and this function being the one to translate it into something the network stack can actually read. iconic.

⭐ RETURN ⭐

• 0 — when there is nothing left to poll for 🎀 (we're done here, slay)
• -1 — when the timestamp is not available yet, and the caller should poll again 😭 (not yet bestie, come back later)
