rio_pw_enable(9)

okay so bestie, welcome to rio_pw_enable(9) from the Kernel API Manual — yes, the RapidIO crew is back, and this one is lowkey the on/off switch for port-write handling. ✨ iykyk.

🌸 NAME 🌸

rio_pw_enable — Enables/disables port-write handling by a master port 💅

✨ SYNOPSIS ✨

Here's the exact signature, no cap:

void rio_pw_enable (struct rio_mport *mport , int enable );

She returns void, so there's no return value to catch — just call her and move on. 🫶

🎀 ARGUMENTS 🎀

• mport — Master port associated with port-write handling 🦋
• enable — 1=enable, 0=disable ✨
