of_find_last_cache_level(9)

🦋 of_find_last_cache_level(9) 🦋

okay so this little icon is straight from the Kernel API Manual, and she's here to answer one very specific question: where's the last cache level at? no cap, that's the vibe 💅

---

✨ NAME ✨

of_find_last_cache_level — finds the level at which the last cache is present for the given logical cpu. that's the whole function, and she ate 🫶

---

✨ SYNOPSIS ✨

the signature is literally this, bestie:

int of_find_last_cache_level (unsigned int cpu );

---

✨ ARGUMENTS ✨

• cpu — the cpu number (logical index) for which the last cache level is needed. lowkey the only argument, and she's giving main character energy 👑

---

✨ RETURN ✨

returns the level at which the last cache is present. it's exactly the same as the total number of cache levels for the given logical cpu — fr fr, that's the number you get back 🌸
