💅 powernow_k6_init(9) — the Kernel API Manual, but make it cute

okay bestie, welcome to the powernow_k6_init page from the Kernel API Manual — yes, that's the manual name, and yes it's giving "ancient kernel lore that still slays" 🧚✨

---

✨ NAME ✨

powernow_k6_init — literally the function that initializes the k6 PowerNow! CPUFreq driver 🎀

---

🌸 SYNOPSIS 🌸

int powernow_k6_init (void );

that's it, that's the whole signature, no cap 💅

---

🦋 ARGUMENTS 🦋

• void — no arguments. nothing. zero. the void is voiding 🙈

---

🔥 DESCRIPTION 🔥

so this function initializes the K6 PowerNow! support ✨ like, it's the one that gets the whole thing up and running.

and because it's a good well-behaved little driver, it tells you how it went via its return value:

• -ENODEV — returned on unsupported devices 😭 (your hardware said "not me", respectfully)
• -EINVAL or -ENOMEM — returned on problems during initialization 💀 so like, bad value or no memory, the classics
• zero — returned on success 👑 and that's the iconique outcome we're all rooting for

ngl the -ENOMEM one is the vibe check nobody wants to fail. fingers crossed for that sweet, sweet zero 🫶
