🌈 rio_basic_attach(9) — Kernel API Manual 🌈

okay bestie, welcome to the Kernel API Manual page for rio_basic_attach(9). This one is short but iconic: it's the attach function for the basic RapidIO enumeration/discovery method. No cap 💖.

---

✨ NAME ✨

rio_basic_attach — the dash after it is followed by literally nothing, so there's no extra one-line description here. Just the function name doing its main-character thing 💅.

🦋 SYNOPSIS 🦋

The signature is giving "I return an int and I take zero arguments":

int rio_basic_attach (void );

🎀 ARGUMENTS 🎀

• void — no arguments. Nothing to pass, nothing to vibe-check, just empty on purpose 🫶.

💅 DESCRIPTION 💅

Okay so when this enumeration/discovery method is loaded as a module, this function registers its specific enumeration and discover routines for all available RapidIO mport devices. That's the whole glow-up ✨.

The "scan" command line parameter controls the ability of the module to start RapidIO enumeration/discovery automatically. So yeah, that parameter is the little switch in charge of the auto-start vibes 👑.

It returns 0 for success or -EIO if it's unable to register itself. Very demure, very clear 😌.

Heads up bestie: this enumeration/discovery method cannot be unloaded and therefore does not provide a matching cleanup_module routine. That's not a missing detail — it's literally how it is, so don't come for it 💀.
