rio_local_set_device_id(9)

💖 NAME 💖

okay so bestie, this is rio_local_set_device_id(9) from the Kernel API Manual — and the whole assignment is literally set the base/extended device id for a port. That’s it, that’s the vibe. 🎀✨

🌸 SYNOPSIS 🌸

here’s the signature, no cap — keep it exact if you’re typing it out:

void rio_local_set_device_id (struct rio_mport *port , u16 did );

🫶 ARGUMENTS 🫶

• port — the RIO master port, aka the port you’re doing the thing to 💅
• did — the Device ID value to be written, literally the value going in ✨

🦋 DESCRIPTION 🦋

okay so what’s the actual tea? It writes the base/extended device id from a device. That’s the whole move. Lowkey tiny, highkey useful, and it does exactly what it says on the label 🫶💖
