tick_offline_cpu(9)

🦋 tick_offline_cpu(9) 🦋

okay so welcome to the Kernel API Manual, bestie — this page is all about tick_offline_cpu, and it's literally the CPU-teardown moment where the lights go off and the broadcast mechanism gets left on read 💅✨

---

✨ NAME ✨

tick_offline_cpu — shutdown all clock events related to this CPU and take it out of the broadcast mechanism 🎀

---

🌸 SYNOPSIS 🌸

void tick_offline_cpu (unsigned int cpu );

it returns void, so no return value era — periodt 💜

---

🎀 ARGUMENTS 🎀

• cpu — the outgoing CPU 👋 like, the one that's packing its bags and heading out 🧳

---

🦋 DESCRIPTION 🦋

Called by the dying CPU during teardown 💀 yes, “dying” is the actual vibe here — it's the CPU's final exit scene, and this function gets the call 🙈✨
