intel_tcc_set_offset(9)

💅 NAME 💅

okay so bestie, this is intel_tcc_set_offset — it sets the TCC offset value to Tjmax. that's it, that's the whole vibe ✨

---

🎀 SYNOPSIS 🎀

int intel_tcc_set_offset (int cpu , int offset );

---

🌸 ARGUMENTS 🌸

• cpu — the cpu that the MSR should be run on, fr fr. drop a negative value in here and it means any cpu, no cap 🫶
• offset — the TCC offset value, and it's in degree C, so like, temperature-coded 💅

---

🔥 DESCRIPTION 🔥

so the whole point: this sets the TCC Offset value to Tjmax. and the way it actually works — the effective thermal throttling temperature, which is also the TCC activation temperature, equals "Tjmax" - "TCC Offset", measured in degree C. literally that simple, the math is mathing 🧚⭐

---

👑 RETURN 👑

on success it returns 0. otherwise you get a negative error code, so if you see a negative number, that's the universe (well, the kernel) telling you something went sideways 😭💀
