okay so this is a page from the Kernel API Manual and it's about pruss_cfg_read(9), and honestly? it's giving "small function, big responsibility." buckle up 🎀

✨ NAME ✨

pruss_cfg_read — read a PRUSS CFG sub-module register 🔥

like, you want a value out of the CFG sub-module? this is the girl for the job.

---

🌸 SYNOPSIS 🌸

int pruss_cfg_read (struct pruss *pruss , unsigned int reg , unsigned int *val );

three args, one int back. clean, minimal, iconic. 💅

---

🦋 ARGUMENTS 🦋

• pruss — the pruss instance handle 🫶 your little passport to the PRUSS world, ngl.
• reg — register offset within the CFG sub-module ✨ so like, which register we're peeking at.
• val — pointer to return the value in 💖 it's a pointer, so the value comes back out through here. yes bestie, out-param behavior, we love a mutable argument.

---

💜 DESCRIPTION 💜

Reads a given register within the PRUSS CFG sub-module and returns it through the passed-in val pointer. that's it. that's the whole vibe. one read, one value, zero drama 🌈

lowkey important: the result doesn't come back as the function's return value — it lands in whatever val points at. don't be out here checking the return value for your register data, bestie 😭

⭐ RETURN ⭐

• 0 on success 🎉 slay.
• or an error code otherwise 💀 (so like, do check it. fr fr.)
