💅 panthor_mmu_init(9) — the Kernel API Manual, but make it cute ✨

okay so bestie, welcome to the Kernel API Manual entry for panthor_mmu_init(9) — yes the whole manual name is in the title, we're not hiding it, we're owning it 🫶. This is the function that gets the MMU logic up and running, and honestly? she's a little iconic for it.

✨ NAME ✨

panthor_mmu_init — literally just Initialize the MMU logic. that's it, that's the whole job 💅

---

🌸 SYNOPSIS 🌸

int panthor_mmu_init (struct panthor_device *ptdev );

one function, one argument, zero drama. we love a low-maintenance queen 👑

---

🎀 ARGUMENTS 🎀

• ptdev — the Device. yeah that's the whole description in the original and honestly? she said "Device." and left. respect. 🦋

---

💖 RETURN 💖

• 0 on success 🎉 — slay, the MMU is up!
• a negative error code otherwise 😭 — not slay, but at least it tells you something went wrong, iykyk

ngl bestie, a negative error code means "go check your stuff", so pls do actually check it and don't just vibe past it 🙈
