inv_mpu_magn_probe(9)

💅 inv_mpu_magn_probe(9) — like, the Kernel API Manual page, bestie 🎀

okay so welcome to the Kernel API Manual entry for inv_mpu_magn_probe(9) — yes that (9) means it's a kernel-section page, we love a section-9 moment ✨

---

🌸 NAME 🌸

inv_mpu_magn_probe — probe and setup the magnetometer chip, no big deal, just making the magnetometer exist properly 🧲✨

---

🦋 SYNOPSIS 🦋

int inv_mpu_magn_probe (struct inv_mpu6050_state *st );

literally the whole signature, copied exactly, because we do not mess with code in this house 💅

---

💖 ARGUMENTS 💖

• st — the driver internal state. that's it, that's the whole vibe. it's the driver's own little state blob and it needs to be handed over 🫶

---

👑 DESCRIPTION 👑

okay so what does this thing actually do? it returns 0 on success, and a negative error code otherwise — periodt, that's the contract 📉

It is probing the chip and setting up all needed i2c transfers. like, it goes and pokes at the hardware and gets all the i2c plumbing ready so everything later just works 🔥

and the iconic part: it's a Noop if there is no magnetometer in the chip. no magnetometer? no problem. it just vibes and does nothing 🙈✨

ngl, that "no magnetometer" case is the main character energy of this whole function — it's not an error, it's just nothing to do 💀
