cpufreq_cooling_register(9)

✨ cpufreq_cooling_register(9) ✨

okay bestie, so this is a page from the Kernel API Manual and it's literally about one little function, but she's an important one 🎀

---

💅 NAME 💅

cpufreq_cooling_register — the function that creates a cpufreq cooling device. that's it, that's the whole gig. she builds the cooling device, no cap ✨

---

🌸 SYNOPSIS 🌸

struct thermal_cooling_device * cpufreq_cooling_register (struct
cpufreq_policy *policy );

like, she takes a policy and hands you back a struct thermal_cooling_device *. a whole glow-up from policy to cooling device, we love a transformation arc 👑

---

🦋 ARGUMENTS 🦋

• policy — a cpufreq policy. that's the whole argument, bestie. just the cpufreq policy, nothing else, she keeps it simple 💖

---

🌈 SEE ALSO 🌈

• the kernel file ./include/linux/cpu_cooling.h — go read her, she's the source of truth 📖
• cpufreq_cooling_unregister(9) — the breakup counterpart, when the cooling device has to go 😭
• of_cpufreq_cooling_register(9) — the device-tree-flavoured sibling, iykyk 🌳

---

ngl this one is short and sweet, so there's not much to warn you about here — but do clock that cpufreq_cooling_unregister(9) is the matching undo, because every register deserves her unregister 🫶

and that's the whole page, fr fr 💜 it's from ./include/linux, dated October 2026, filed under the Kernel API Manual — mwah, go forth and cool those cpus 🧚⭐
