I can reproduce the bug with AMD Ryzen 2500u powered HP Envy x360 convertible laptop. tuned.log

Version installed on Fedora 32 is 2.13.0. It seems tuned have not fully tested on AMD hardware and builtin cpufreq_conservative module hence the following errors:

2020-05-05 19:16:48,311 ERROR    tuned.utils.commands: Executing modprobe error: modprobe: FATAL: Module cpufreq_conservative is builtin.

Only the old radeon driver supported those tweaks, and they shouldn't be used anymore: https://lists.freedesktop.org/archives/amd-gfx/2020-September/053717.html

Just use "dpm-battery", "dpm-balanced", or "dpm-perfomance" instead https://github.com/redhat-performance/tuned/blob/master/tuned/plugins/plugin_video.py

FWIW, I was told that those values shouldn't be changed at all: https://lists.freedesktop.org/archives/amd-gfx/2020-September/053717.html

I see that power_dpm_state is also meaningless The diffrence between power_method and power_dpm_state is that the former throws "No such file" error and the latter does not Thank you

Hi. I updated video_plugin on my fork, but don't have access to newer radeon GPU (yet). Can somebody please check it before I update docs and tests? https://github.com/CZerta/tuned/tree/radeon_powersave_update

[WhiteCat6142]

The patch worked fine on my RX5600XT. (I'm not sure "amdgpu / radeon" detect works properly. If it is compatible with some older systems, it should be marged, I think.)
