💅 rio_local_get_device_id(9) — the Kernel API Manual glow-up ✨

okay so bestie, welcome to the Kernel API Manual page for rio_local_get_device_id(9) and honestly? it's a little cutie. lowkey one job, does it well. let's get into it 🫶

---

🌸 NAME 🌸

rio_local_get_device_id — get the base/extended device id for a port, fr fr that's the whole vibe ✨

---

🎀 SYNOPSIS 🎀

u16 rio_local_get_device_id (struct rio_mport *port );

that's it. one arg, one u16 coming back at you. iconic behavior honestly 👑

---

🦋 ARGUMENTS 🦋

• port — the RIO master port you're pulling the deviceid from. that's your main character right there 💖

---

✨ DESCRIPTION ✨

so what does it actually do? it reads the base/extended device id from the local device that's implementing the master port. then it hands you back the 8/16-bit device id. that's the whole quest. no cap, no side plots, just the id 🎀

like it's giving "small function, big confidence" and we respect it 💅

and that's the whole page bestie, you ate that 💅✨

sign-off time 🫶 this one comes from ./drivers/rapidio and it's dated October 2026 — so yes, she's from the future and she's still just returning a device id. queen behavior 👑💖
