💅 tsi721_setup_mport(9) — the Kernel API Manual glow-up 🎀

okay so bestie, welcome to the Kernel API Manual entry for tsi721_setup_mport(9). yes that's a mouthful, no you don't have to say it out loud. this is the function that makes the Tsi721 chip step into its main character era as a RapidIO master port ✨

🌸 NAME 🌸

tsi721_setup_mport — Setup Tsi721 as RapidIO subsystem master port

like, it literally sets up the Tsi721 as a RapidIO subsystem master port. that's the whole vibe. no cap 💅

🦋 SYNOPSIS 🦋

int tsi721_setup_mport (struct tsi721_device *priv );

🎀 ARGUMENTS 🎀

  • priv — pointer to tsi721 private data 🫶

that's it. one argument. one. and it's just the private data pointer for the tsi721 device. lowkey refreshing ngl 😌

✨ DESCRIPTION ✨

Configures Tsi721 as RapidIO master port.

fr fr, that's what it does — it does the configuring, Tsi721 becomes the RapidIO master port, and the whole thing slays. it's giving "tiny function, huge responsibility" energy. main character behaviour only 👑🔥

💖 RETURN 💖

  • 0 on success 🌈
  • -errno value on failure 💀

so like, check the return value, bestie. 0 means we ate and left no crumbs. a negative errno value means something went sideways and you should go look at that. periodt 🙈
