okay so bestie, this is the intel_tcc_get_tjmax(9) page from the Kernel API Manual, and it's literally about one function: intel_tcc_get_tjmax — the one that returns the default TCC activation Temperature. that's the main-character job, no cap 💖.

✨ SYNOPSIS ✨

int intel_tcc_get_tjmax (int cpu );

that's the signature exactly as written, spacing and all — canon is canon, bestie 💅.

🌸 ARGUMENTS 🌸

• cpu — the cpu that the MSR should be run on, bestie. a negative value means any cpu. slay 🦋.

🦋 DESCRIPTION 🦋

💖 RETURN 💖

• on success: the Tjmax value in degrees C. iconic ✨
• otherwise: a negative error code. not iconic, but useful 😭.
