fsl_rio_pw_enable(9)

💖 NAME 💖

okay so bestie, this page is fsl_rio_pw_enable(9) — from the Kernel API Manual, no cap. It's the function that does enable/disable port-write interface init. Literally what it says on the tin. 🫶

✨ SYNOPSIS ✨

int fsl_rio_pw_enable (struct rio_mport *mport , int enable );

🎀 ARGUMENTS 🎀

• mport — the master port that implements the port write unit. That's the main-character struct here. 👑
• enable — 1 = enable; 0 = disable port-write message handling. So yes, it's a little on/off switch, and the numbers mean exactly that. 💅
