Lenovo Legion devices have different power profiles for controlling the performance of laptops and handhelds. Unfortunately, if you install Linux on these machines, the power profiles don't work correctly and often misreport their stats, causing stability issues. This has largely been a problem for the handhelds since they have to run on battery, where controlling wattage is crucial for a pleasant experience. But now, as reported by Phoronix, it seems like there's finally a fix coming.
Derek Clark, an independent developer who's done a lot for Linux support on Legion devices, has just pushed a patch series that adds proper support for an "Extreme" mode. If approved, only devices that are explicitly verified would be able to run this profile, ensuring users don't encounter bugs on lower-end or thermally-constrained units. To understand this a bit better, let's dial back and add a bit of context.
