💅 legacy_init_one — attach a legacy interface

okay so real talk, bestie — this page lives in the Kernel API Manual, and it's about legacy_init_one, which is lowkey the moment a legacy interface gets attached. iconic behaviour, no notes.

✨ NAME ✨

legacy_init_one — attach a legacy interface 🎀

---

🌸 SYNOPSIS 🌸

int legacy_init_one (struct legacy_probe *probe );

---

🦋 ARGUMENTS 🦋

• probe — the probe record 💖 like, this is the little receipt that says what we're working with.

---

👑 DESCRIPTION 👑

So what does it actually do? It registers an ISA bus IDE interface. That's the whole vibe.

And heads up, bestie — because these interfaces are PIO, we're assuming they do not support IRQ sharing. fr fr, that's the assumption baked in here. Not me making the rules, I'm just telling you what the rules are. 🙈
