I have an Framework Laptop with i7-1165G7 and Pop!_OS 22.04 installed. Recently I noticed that under sustained load (e.g. Blender Benchmark) the CPU would initially have high clock speeds but after around 40 s throttle to 2.8 GHz (its base clock).
As per my monitoring the CPU is set to performance mode and doesn’t overheat.
Even while boosting package power stays always below 30 W (the official PL1 that Framework) configured. Whats odd is that my PL1 reading says 200 W. The 200 W PL1 reading is confirmed by the value inside the model specific registers or other tools like CoreFreq. I never observed the CPU go above 30 W or anywhere near the PL2 of 64 W.
Initially the CPU would boost to higher frequencies until it reaches 30 W package power.
After several web searches I still don’t have a clue whats wrong or what could explain the behavior.
Is this normal behavior under Linux?
Is it possible to keep the CPU boosting above base clock indefinitely like on Windows?
