I will make sure I have your exact settings. Does frame buffer affect
acceleration of amdgpu?

Not sure what do you mean Ryzen card. I don't have APU. just AMD CPU Ryzen
1600.

currently i am trying to get rid of this:
/usr/lib64/dri/swrast_dri.so failed (libLLVMAMDGPUCodeGen.so.8: cannot open
shared object file: No such file or directory)

i am recompiling mesa, because it was compiled with old LLVM I suspect.
Once I do that i will try your config.
