intel_tcc_get_offset(9)

💖 NAME 💖

okay bestie, this is intel_tcc_get_offset(9) from the Kernel API Manual, and she has one very specific job: intel_tcc_get_offset returns the TCC Offset value to Tjmax. periodt 💅

---

✨ SYNOPSIS ✨

int intel_tcc_get_offset (int cpu );

one int goes in, one int comes out, no cap 🫶

---

🎀 ARGUMENTS 🎀

• cpu — the cpu that the MSR should be run on. A negative value means any cpu. iykyk 🌸

---

🌸 DESCRIPTION 🌸

Get the TCC offset value to Tjmax. That's the whole vibe check.

The effective thermal throttling or TCC activation temperature equals "Tjmax" - "TCC Offset", in degrees C. so yes, the formula is literally right there and it's giving math class but make it thermal 🔥

---

🔥 RETURN 🔥

On success, you get the Tcc offset value in degrees C. Otherwise, you get a negative error code. that's it, that's the whole return arc 😭
