cpuidle_unregister_driver(9)

💅 cpuidle_unregister_driver 💅

okay so welcome to the Kernel API Manual, bestie — this page is all about cpuidle_unregister_driver, and it’s giving “clean up your driver registration” energy ✨

---

🎀 NAME 🎀

cpuidle_unregister_driver — unregisters a driver 💅

---

✨ SYNOPSIS ✨

void cpuidle_unregister_driver (struct cpuidle_driver *drv );

---

🫶 ARGUMENTS 🫶

• drv — a pointer to a valid struct cpuidle_driver ✨

---

💖 DESCRIPTION 💖

So this function unregisters the cpuidle driver, and it does it under a lock so that concurrent attempts to [un]register the driver can’t happen at the exact same time. Lowkey crucial, fr fr 🔥

The drv you pass in has to match the driver that’s currently registered — that’s the vibe check, and it must pass 💅
