[BUG] Incorrect CPU Long Term Power Limit (Cross Loading) applied and cannot be changed

[mesaprotector]

Installed lenovolegionlinux-git and lenovolegionlinux-dkms-git from the AUR a couple days ago to be able to see fan speeds on Linux. I use Windows 11 for gaming. The very next time I booted into Windows, I observed abnormally low FPS in-game.

Had not updated the Windows driver, or changed any Windows settings at all for at least two weeks prior to this happening. Doing a clean reinstall of the Windows driver did not help. I use Lenovo Legion Toolkit on Windows and had not changed its settings either.

All I did with LenovoLegionLinux is load into the GUI, check the various fan curves, enable the daemon and logging, and exit - and then I disabled the daemon and logging again after finding this issue, but it did not fix the problem.

I found a workaround, which is to use Custom Mode on Windows and raise the CPU Power Limit (Cross-Loading), in my case from 30 to 45 watts. Even when the GPU was not being fully used, the CPU was underutilized, which was never the case before. I should note that this value cannot be set (is not read correctly) in LenovoLegionLinux. It is listed as 0 and if I try to set to anything it reverts to 0.

Haven't found a way to fix the FPS drops on Performance Mode, unfortunately. I suppose this isn't high priority but I'll leave the issue here in case anyone else has this problem.
