zl3073x_dev_start(9)

💖 zl3073x_dev_start 💖

okay so bestie, welcome to the zl3073x_dev_start(9) page — this is from the Kernel API Manual, and honestly? it's giving "tiny function, big responsibilities" energy. like, this is the main character of bringing the whole zl3073x device to life. 🦋

---

✨ NAME ✨

zl3073x_dev_start — start normal operation. that's it, that's the vibe. it literally gets the party going 🎀

---

🌸 SYNOPSIS 🌸

int zl3073x_dev_start (struct zl3073x_dev *zldev , bool full );

like look at her. two arguments, one int return, zero drama. slay 💅

---

🧚 ARGUMENTS 🧚

• zldev — zl3073x device pointer. yeah bestie you gotta tell her which device we're starting, she's not a mind reader 😭
• full — perform full initialization. set this to true and she goes the extra mile, no cap 🌈

---

👑 DESCRIPTION 👑

so here's the tea, fr fr: this function starts normal operation. and what does that actually mean? glad you asked 🫶

• it registers all the DPLLs and their pins
• and it starts monitoring

that's the base package. cute, right? but wait — there's more ✨

if full initialization is requested (aka full is true), she additionally:

• initializes the phase offset measurement block
• fetches hardware-invariant parameters

so like, it's the same function but she brought extra snacks. lowkey iconic 🍓

ngl, if you're not sure whether you want the full version — that's a you problem, the manpage doesn't tell you. it just says what it does. i'm not out here inventing behaviour 😤

---

⭐ RETURN ⭐

• 0 on success 🎉
• <0 on error 💀

that's the whole return contract. zero means we ate, negative means something went sideways. periodt.
