devl_params_register(9)

💅 devl_params_register — Kernel API Manual ✨

Okay so bestie, gather round, because this one is giving infrastructure main character energy 🎀. We're looking at devl_params_register(9), which lives in the Kernel API Manual, and it's basically the bouncer at the club that lets your driver's configuration parameters actually get in. No cap.

✨ NAME ✨

devl_params_register — register configuration parameters 🦋

Like, the whole vibe of this function is "hi yes I would like to make these parameters official please."

---

🌸 SYNOPSIS 🌸

int devl_params_register (struct devlink *devlink , const struct
       devlink_param *params , size_t params_count );

It returns an int, so yeah, you get a return value to check. Please actually check it. 🙈

---

💖 ARGUMENTS 💖

• devlink — the devlink instance, obviously. Your main character struct 💅
• params — the array of configuration parameters. Yes, an array. Plural. Bring friends 🌈
• params_count — literally just how many parameters you handed over, bestie. The count. The number provided 🔢

---

👑 DESCRIPTION 👑

Register the configuration parameters supported by the driver. That's it, that's the whole thing — you're telling the kernel "these are my params, they're real, they're official, please respect them" ✨

---

🫶 SEE ALSO 🫶

Kernel file ./net/devlink/param.c plus the whole friend group:

• devl_params_unregister(9)
• devl_param_driverinit_value_get(9)
• devl_param_driverinit_value_set(9)
• devl_param_value_changed(9)

---

ngl, if you register them you should also know how to unregister them. Just saying. Balance. 🧚

And that's the tea, bestie 🍓 — this little icon dropped in ./net/devlink back in October 2026, and it's been slaying in the Kernel API Manual ever since 💜⭐
