nvec_register_notifier(9)

💅 nvec_register_notifier — a Kernel API Manual moment

okay so bestie, we're in the Kernel API Manual today and this page is literally called nvec_register_notifier(9) — say that three times fast, I dare you 🫶

---

✨ NAME ✨

nvec_register_notifier — Register a notifier with nvec. that's it, that's the whole name, and she ate 💅

---

🦋 SYNOPSIS 🦋

int nvec_register_notifier (struct nvec_chip *nvec , struct
notifier_block *nb , unsigned int events );

look at her go. three args, one int coming back at you, no cap ✨

---

🎀 ARGUMENTS 🎀

• nvec — A struct nvec_chip. it's the chip struct, she's the main character of this whole file ngl 👑
• nb — The notifier block to register. this is the thing you're handing over so it can get called later 🫶
• events — Unused. literally unused, bestie. don't come for me, I don't make the rules 💀

---

🌸 DESCRIPTION 🌸

So here's the tea ☕ — this function registers a notifier with nvec. The notifier gets added to an atomic notifier chain (yes, atomic, so act accordingly 🔥).

That chain gets called for all received messages… except the ones that correspond to a request initiated by nvec_write_sync. those ones? not invited to the party 🙈

the way that's the entire behaviour and it's still iconic. periodt ✨
