IPA POWER MANAGEMENT(9)

💖 IPA Power Management 💖

okay so bestie, welcome to the Kernel API Manual, section 9 — this is the IPA power-management page and it's lowkey iconic. The IPA hardware is enabled when the IPA core clock and all the interconnects (buses) it depends on are enabled. all of them, no cap 🫶.

Runtime power management is the main character here: it's used to determine whether the core clock and interconnects are enabled, and if they're not in use, they get suspended automatically. so it's not just sitting there vibing, okay? 😭✨

The core clock currently runs at a fixed clock rate when enabled, and all interconnects use a fixed average and peak bandwidth. that's the current setup, fr fr 💅.
