thermal_set_governor(9)

💅 thermal_set_governor(9) — Kernel API Manual energy ✨

okay so bestie, welcome to the thermal_set_governor page, straight out of the Kernel API Manual 🎀 this one's short and sweet but she's important, so pay attention okay?

---

✨ NAME ✨

thermal_set_governor — switch to another governor 🔁👑

like, the whole personality of this function is "swap out the governor" and honestly? iconic.

---

🌸 SYNOPSIS 🌸

int thermal_set_governor (struct thermal_zone_device *tz , struct
       thermal_governor *new_gov );

she takes two things and she returns an int, that's the whole vibe 🫶

---

🦋 ARGUMENTS 🦋

• tz — a valid pointer to a struct thermal_zone_device ⭐ bestie please make it valid, this is not the place for a silly little garbage pointer okay 😭
• new_gov — pointer to the new governor 👑 this is the one sliding into the role

---

💜 DESCRIPTION 💜

Change the governor of thermal zone tz. that's it, that's the whole job 💅✨ new governor, new era, main character energy fr fr.

---

🔥 RETURN 🔥

• 0 on success 🎉 slay, we love a clean zero
• an error if the new governor's bind_to_tz failed 💀 like, the glow-up didn't stick

ngl if you get the error back it means the bind_to_tz of the new governor didn't work out — so don't go assuming the swap happened 🙈
