💅 cpuidle_cooling_set_cur_state(9) — the whole vibe

okay so first things first, bestie: this page lives in the Kernel API Manual ✨ and the header up top literally spells it cpuidle_coo...et_cur_state(9) because somebody's terminal was Not Wide Enough 😭 but like... we know her. she's cpuidle_cooling_set_cur_state. iconic name, no notes.

🌸 NAME 🌸

cpuidle_cooling_set_cur_state — literally just Set the current cooling state 🧊✨ that's the whole job.

---

🦋 SYNOPSIS 🦋

int cpuidle_cooling_set_cur_state (struct thermal_cooling_device *cdev ,
unsigned long state );

yes the spacing is like that, don't @ me, copy it exactly 💅

---

🎀 ARGUMENTS 🎀

• cdev — the thermal cooling device 🫶 like, the actual device we're messing with.
• state — the target state 🎯 the state we're aiming for. the goal. the dream.

---

✨ DESCRIPTION ✨

okay so here's what happens, fr fr. The function checks first whether we're initiating the mitigation 👀 and that, in turn, wakes up all the idle injection tasks belonging to the idle cooling device 😴➡️🔥 so everybody's up and doing their little jobs.

And in any case — like, no matter what happens with that check — it updates the internal state for the cooling device 💖 so the state is always fresh, always updated, always that girl.

---

🔥 RETURN 🔥

ngl this one is genuinely stress-free: The function can not fail — it is always zero. 0️⃣🫶 no error codes, no drama, no crying in the group chat. slay.
