pruss_cfg_xfr_enable(9)

💅 pruss_cfg_xfr_enable(9) — from the Kernel API Manual, bestie ✨

Okay so picture this: you're deep in the kernel, you've got a PRUSS (that's the programmable real-time unit subsystem, iykyk), and you need to flip the XIN/XOUT shift thingy on or off. That's literally this function. One call, one little enable flag, and the shift functionality is either slaying or napping. 🎀

✨ NAME ✨

pruss_cfg_xfr_enable — enables or disables the XIN XOUT shift functionality. That's the whole job. No cap. 🦋

---

🌸 SYNOPSIS 🌸

int pruss_cfg_xfr_enable (struct pruss *pruss , enum pru_type pru_type ,
       bool enable );

Look at her. Three args, returns an int. Main character energy fr fr. 💖

👑 ARGUMENTS 👑

• pruss — the pruss instance. Like, the one. Your whole PRUSS vibe lives here. 🫶
• pru_type — a PRU core type identifier. It tells the function which PRU core type we're talking about, because there's more than one and they're all iconic in their own way. ⭐
• enable — enable/disable. A humble bool doing the heavy lifting: true-ish means turn it on, false-ish means turn it off. She's simple, she's powerful. 💅

---

🔥 RETURN 🔥

Returns 0 on success, or an error code otherwise. So like… check it, bestie. 0 is the good ending. Anything else is the kernel telling you something went sideways. 😭

The kernel file has the receipts: ./drivers/soc/ti/pruss.c — go read her, she ate. 🍓

And the whole friend group:

lowkey go read those too, they're all part of the same little ecosystem and they'd be jealous if you only talked to this one 🙈
