batocera.linux VS RyzenAdj

& here's their official website

The OS you probably want is Batocera. I have a couple external SSDs that I use to run it on my VCSs, and they're great. It's definitely an easier setup than Windows with Launchbox, and you don't have to deal with licensing, forced updates, and all the other Windows garbage.

This subreddit is for the completely free and open-source distribution that you would find at https://batocera.org/ which comes with absolutely no copyrighted ROMs(games). You will only get support here for that and that alone. Unfortunately if you bought a preconfigured system ("unofficial image"), your issues are with the people who sold it to you. Nobody here can help you with anything outside the scope of the official release of Batocera. Which does have thorough documentation; https://wiki.batocera.org/

You made this post on the Github as the bug report, right? https://github.com/batocera-linux/batocera.linux/issues/8905

This is the only issue I could find and says it has been fixed a few weeks back. https://github.com/batocera-linux/batocera.linux/issues/8722

Alternatively, since you just built a nice PC, you can take the free options and just software emulate classic systems and run MAME. If you don't have time to set much up, look into a Batocera boot drive https://batocera.org/

Out of curiousity how the 7840HS performs at different TDP, I did some benchmarks using Geekbench 6.2.0. To change the TDP, I've used the software RyzenAdj like so:

TLDR: Ryzen Adj.

A few years ago I did a bunch of poking w/ a 4800H, you can see the actual mechanics of using RyzenAdj. There are also Geekbench 5 benchmarks linked from the doc at different power limits which you can compare to 4800U devices on Geekbench's site: https://github.com/lhl/linuxlaptops/wiki/2020-MECHREVO-Code-...

Note, each laptop manufacturer may choose their different power limits (and like Intel, AMD's curves are largely driven by temperature, so dependent on cooling solution and other settings).

This is a good summary of some of how Ryzen Mobile's power limiting works (actually, read that whole wiki if you're interested in the topic): https://github.com/FlyGoat/RyzenAdj/wiki/Renoir-Tuning-Guide

I'd also look up "AMD PMF" (their equivalent of DPTF) which only recently made it's way to the Linux kernel (but of course, that will include loads of details anyone can look through): https://www.phoronix.com/news/AMD-PMF-CnQF-Linux-6.1

That app just uses (under the hood) this one https://github.com/FlyGoat/RyzenAdj - g-helper not using that , as it requires admin rights to run :)
