Then, I was able to run a game using DRI_PRIME=1 and use the full power of my GPU. I'm uploading some files to show the results of the two cases (radeon.dpm=0 and radeon.dpm=1), and also the full dmesg of both runs. Note that when DPM is enabled, the GPU load gets stuck at 100%, even if it is capable of performing way better. The problem I'm facing now is that the computer gets way hotter when disabling DPM, even when idle. In any case, hope this results can help somehow.

Comment # 20 on bug 94708 from 
Ok, so I've managed to get my discrete GPU running by disabling DPM (by adding
GRUB_CMDLINE_LINUX_DEFAULT="radeon.dpm=0" to the grub configuration file).
Then, I was able to run a game using DRI_PRIME=1 and use the full power of my
GPU. 

I'm uploading some files to show the results of the two cases (radeon.dpm=0 and
radeon.dpm=1), and also the full dmesg of both runs. Note that when DPM is
enabled, the GPU load gets stuck at 100%, even if it is capable of performing
way better.

The problem I'm facing now is that the computer gets way hotter when disabling
DPM, even when idle. In any case, hope this results can help somehow.

Cheers,
Arthur
