I've been having this annoying problem that on my i5 10210U, which has a PL1 of 15 watts and PL2 of 31 watts, in any Linux distro it would not go over 15 watts. I've tried Debian and Arch and both have the same problem. I have tried a LOT of troubleshooting tools but they didn't work. On another laptop which is not mine, I tested Linux and it had no problem clamping to PL2. I suspect that its BIOS has a lot more features, including the ability to alter turbo boost and some power management, but my BIOS doesn't give much control on power at all. So this means it leaves the power control on the OS itself? But if it works on Windows, so should it on Linux. I am sure I am missing some software or some component which handles this part. I tried compiling my own Kernel with some boxes checked regarding power, but after so much time spent compiling, I get some error in the end. Does somebody know what I am looking for?
