Okay so bestie, welcome to sumo_pm_init_profile(9) from the Kernel API Manual 💖. This page is literally here to initialize that power profiles callback. That's the whole assignment, no cap ✨.

🎀 SYNOPSIS 🎀

Here's the signature, copied exactly because we do not mess with code:

🌸 DESCRIPTION 🌸

Okay so what it does: it initializes the power states used in profile mode — specifically sumo, trinity, and SI ✨. And bestie, listen: this is used for profile mode only. No extra modes, just profile mode 💅.
