💅 smp_cpuid_part(9) — Kernel API Manual

okay bestie, welcome to the smp_cpuid_part(9) page ✨ this is a lil kernel manpage from the Kernel API Manual, and honestly? it's short, it's sweet, it's giving minimal icon energy 🎀

---

✨ NAME ✨

smp_cpuid_part — return part id for a given cpu 🧚‍♀️

like, that's the whole job. you hand it a cpu, it hands you back a part id. no cap. 🌸

---

✨ SYNOPSIS ✨

unsigned int smp_cpuid_part (int cpu );

yes that's literally it, one function, unsigned int out, int in 🫶 the type signature stays exactly like that, don't @ me 💅

---

✨ ARGUMENTS ✨

• cpu — the logical cpu id 🙈 that's the one you're asking about. logical, bestie. logical. not physical, not "vibes-based", logical. ⭐

---

✨ RETURN ✨

it returns the part id of the logical cpu you passed as the argument 👑 so like, you give it cpu, it gives you back that cpu's part id. one in, one out, main character function behaviour fr fr 💖

---

✨ SEE ALSO ✨

• Kernel file ./arch/arm/include/asm/smp_plat.h 🦋 go read it, it's right there, iykyk 📖✨

---

lowkey a reminder: this page is describing exactly what it says and nothing more, so don't go inventing extra behaviour for it, bestie 😭 the docs said what they said 💀

---

and that's the whole vibe check, bestie 🌈💜 this lil page is from the kernel source tree at ./arch/arm/include/asm, stamped October 2026 — mwah, slay, periodt 🎀🔥🫶
