okay so bestie, this page is from the Kernel API Manual, and it’s giving “tiny private helper during initialization” energy. let’s get into it 🫶

✨ SYNOPSIS ✨

int set_platform_caps (struct pp_hwmgr *hwmgr , uint32_t powerplay_caps
);

• hwmgr — Pointer to the hardware manager. iconic little pointer moment, no cap.
• powerplay_caps — the bit array (from BIOS) of capability bits. Exception: the current implementation always returns 1. yes bestie, that’s the exception — noted and everything 😭
