AMD rDNA2 setup on silverblue

Project Discussion
1

I’m trying to figure out what is needed to get the most out of the rDNA2 SIENNA_CICHLID gfx on silverblue.

With recent kernel 5.9.15-200.fc33.x86_64 it works out of the box, it looks and feels good even on wayland.

However i tried to get hardware acceleration working on chrome/brave from within toolbox and I had to install mesa-libGL package to get it working.

So I have a few questions:

  • Do I need to install mesa-libGL using rpm-ostree
  • Is mesa-libGL the right thing to install in the first place or is there some other package to install
  • If I install the libva and glx-utils inside toolbox and it shows me that hardware acceleration is working… is it working only inside the container or on the host as well ?

I’m trying to avoid any changes to the core os using rpm-ostree entirely but how do I tell if my wayland session is hardware accelerated without installing necessary packages on the host?

Installing packages on the host for testing / validating is fine and won’t break your guarantee :slight_smile:.

In this case, you can list the packages included in the host image with rpm -qa and mesa-libGL is most probably included.

Remember that applications launched from the toolbox do not share the host installed packages (/usr). They share your home content, the kernel and devices.
