I have been using a 6800U on Linux for the past two weeks. With kernel 5.18 almost everything is supported out of the box. The few issues I have:
- Kernel logs show that the GPU driver crashes from time to time. When it happens the screen freezes for a few seconds but recovers.
- HVEC hardware decoder gives green artifacts on VLC using VA-API.
- It seems not to support advanced power management, on battery the CPU will happily boost to 4.7 GHz which in my opinion makes little sense. AMD has been steadily pushing work related to power management so I expect it to improve. As it stands total power consumption on battery averages 5.1 W.
- ChuckNorris89 4y agoCan I ask which laptop that is?
- nicolaslem 4y agoSure, HP 845 G9.
- lhl 4y agoAMD does automatically switch to a "power saving" profile on battery that lowers power consumption significantly vs on charger, but if you want, you can tweak even further with a fantastic tool: https://github.com/FlyGoat/RyzenAdj https://github.com/FlyGoat/RyzenAdj - it's a simple CLI util so easy to set up w/ udev rules to run automatically. On my old Ryzen laptop, I have it set to run `ryzenadj -f 48` when I go on battery, which limits the temperature below my laptop's fan hysteresis for a very efficient and totally silent system, and `ryzenadj -f 95` to set it back, but you can also adjust most power and clock parameters (not everything works on Ryzen 6000 yet, but the basics should). The docs/wiki are also great and has lots of charts illustrating what each setting does: https://github.com/FlyGoat/RyzenAdj/wiki/Renoir-Tuning-Guide https://github.com/FlyGoat/RyzenAdj/wiki/Renoir-Tuning-Guide The other tool you could check out (and use in conjunction or instead of ryzenadj) is a tool called auto-cpufreq: https://github.com/AdnanHodzic/auto-cpufreq https://github.com/AdnanHodzic/auto-cpufreq - it lets you switch governor and turbo/clock speeds automatically base on battery if you're just looking for a simpler way to set that. 5.19 has a bunch of amdgpu fixes that might fix some things https://lists.freedesktop.org/archives/dri-devel/2022-April/351458.html https://lists.freedesktop.org/archives/dri-devel/2022-April/... but sadly there are often also sometimes regressions/weird bugs: https://gitlab.freedesktop.org/drm/amd/-/issues?page=90&sort=priority&state=all https://gitlab.freedesktop.org/drm/amd/-/issues?page=90&sort...
- rowanG077 4y agoIs it possible somehow to set separate CPU/GPU power limits like is possible on the steam deck?
