💖 devm_peci_controller_add(9) 💖

ok so bestie, welcome to the Kernel API Manual ✨ we're talking about devm_peci_controller_add today and honestly? it's a whole vibe. it's the function that officially announces your PECI controller to the world. main character energy fr fr 🎀

✨ NAME ✨

devm_peci_controller_add — add PECI controller 🦋

like, that's it. that's the whole job. adding a PECI controller. iconic behavior, no notes 💅

---

🌸 SYNOPSIS 🌸

struct peci_controller * devm_peci_controller_add (struct device *dev ,
const struct peci_controller_ops *ops );

look at her. she takes two things and she gives you back a controller. we love a queen who knows what she wants 👑

---

🫶 ARGUMENTS 🫶

• dev — the device, bestie 💖 this is the one used for all the devm operations (iykyk — devm = managed, so the lifecycle stuff handles itself, we literally love that for us).
• ops — a pointer to the controller specific methods 🧚 this is where the controller's own personality lives.

---

🔥 DESCRIPTION 🔥

okay so picture this: your peci_controller driver is in the final stage of its probe, right? like, the last little moment before it steps out fully dressed 💅 and that's exactly when it calls devm_peci_controller_add — to register itself with the PECI bus. that's the whole thing. that's the slay. it's giving debutante ball, it's giving "everybody look at my controller" 🌈⭐

no cap, that's genuinely the entire description. short and iconic. periodt. 💀✨

---

💜 RETURN 💜

• a pointer to the newly allocated controller 🎀 (yay!! the good ending)
• or an ERR_PTR in case of failure 😭 (the bad ending — always check, bestie, please check, do not skip the check, I am begging 🙈)

---

👑 SEE ALSO 👑

• Kernel file ./drivers/peci/core.c — go read it, it's where the magic actually happens 🔥📖

---

tiny reminder from your girl: the return value can be an ERR_PTR, so vibe-check it before you dereference it, okay? protect yourself 💖

and that's the page!! 🌸 this one came out of ./drivers/peci in October 2026, from the Kernel API Manual — love her, read her, cite her 🫶✨ mwah, bye bestie! 💜🦋🎀
