iavf_poll_virtchnl_msg(9)

💅 iavf_poll_virtchnl_msg — kernel API manual, but make it make sense 🎀

okay so bestie, we're looking at iavf_poll_virtchnl_msg(9) from the Kernel API Manual. Yes, that's a mouthful, and yes, it's giving "driver internals that only your one Intel-obsessed mutual understands" — but honestly? It's not that deep, and you're gonna slay this. 💖

✨ NAME ✨

iavf_poll_virtchnl_msg — and that's literally it, no cap. The original page just leaves the description hanging there like a text back you're never gonna get. 🙈 So: this is the function, and everything below is the whole story.

---

🌸 SYNOPSIS 🌸

int iavf_poll_virtchnl_msg (struct iavf_hw *hw , struct
       iavf_arq_event_info *event , enum virtchnl_ops op_to_poll );

Three args, one int back. Simple, iconic, no notes. 👑

---

🦋 ARGUMENTS 🦋

• hw — the HW configuration structure. Your hardware's whole personality in one struct, lowkey. 💜
• event — the event to populate on success. Like, if the poll works out, this is where the good news lands. 🎀
• op_to_poll — the requested virtchnl op to poll for. You tell it which opcode you're waiting on, and it goes looking. iykyk. 🔍

---

⭐ DESCRIPTION ⭐

So here's the vibe: this function initializes a poll for a virtchnl msg that matches the requested op (that's your op_to_poll, bestie). 💅

What you get back:

• 0 — a message of the correct opcode is chilling in the queue. We love a success story. ✨
• an error code — if no message matching the op code is waiting, or there are other failures. 😭

That's fr fr the whole thing. It polls, it checks, it reports. Main character energy, minimal drama.

lowkey important: it's not just "no matching message" that gets you an error — "other failures" count too, so don't assume an error code always means the queue was empty. 🫶
