I cannot get Turbo Boost working on Linux for my Intel Kaby Lake R processor (i7-8650u), always below 10W, 2.1GHz. Current throttling. #Surface #Laptop

This is the same post I made on Reddit but unfortunately I couldn't get much attention. It's seems here is a bit more professional, I am hoping someone can help me, thank you. It's a laptop from Microsoft, Surface Book 2. I run Fedora Linux and Arch Linux, both of them have this issue...

It's a laptop from Microsoft, Surface Book 2. I run Fedora Linux and Arch Linux, both of them have this issue. Either vanilla kernel
or surface kernel
has the same problem.
I've tried most solution: cpupower
tlp
thermald
throttled
power-profiles-daemon
intel-pstate
s-tui
turbostat
disable SecureBoot
I still cannot get it working.
The CPU is not hot, neither power throttling. I can get it up to 4.2GHz
, 35W package
on Windows with Throttlestop
These digits are What I've never seen on Linux.
It always stays below 2.1GHz
, 1.3GHz
when all core are stressed, always below 55C. I've made sure, TurboBoost
is on.
I've opened these post looking for similar experience, not many responds.
Book2 (15") - No CPU Turbo Boost (always below 2.0GHz)
What's the maximum CPU frequency you can get on Linux with your Surface?
This is the performance I got on Windows
