STRUCT CPUIDLE_COOLING_DEVICE(9)

✨ NAME ✨

struct cpuidle_cooling_cooling_device — wait, no bestie, it's struct cpuidle_cooling_device 💅 — and it's literally just the data for the idle cooling device. That's the whole vibe. It holds stuff. It's a struct. Iconic behavior, honestly.

🎀 SYNOPSIS 🎀

struct cpuidle_cooling_device {
    struct idle_inject_device *ii_dev;
    unsigned long state;
 };

Yes, that's the entire struct, no cap. Two members. It's giving minimalist queen. 🦋

🌸 Members 🌸

• ii_dev — an atomic that keeps track of the last task exiting the idle cycle 👀 like it's literally the record keeper of who dipped out of the idle cycle last. Not me being obsessed with an atomic. 🔥
• state — a normalized integer that gives the state of the cooling device ✨ normalized! integer! cooling device state! she's tidy, she's orderly, she knows her value (it's an integer, it's normalized, it's the state). 💜

👑 SEE ALSO 👑

• Kernel file: ./drivers/thermal/cpuidle_cooling.c 🍓 (yes, that's where the real code lives, go read it, iykyk)

ok bestie that's the whole page, no notes 💀 two struct members, seven SEE ALSOs, and a file path. we ate. 🫶

Later, from ./drivers/thermal 🌈, dropping in October 2026 — mwah, slay, periodt. 🎀💖
