AMDGPU hardware decoding/encoding: vdpau or vaapi?

[gradinaruvasile]

I was researching for a EPYC or Threadripper "server" (as in made of parts)solution and for the 2U form factor therte is little info out there...

Depends what fan are you referring to. I have an APU so no dedicated GPU, can't say about that.
The CPU fan though is dynamically controlled by...

On the APUs (2200G and suppose 2400G too) it works really well with Debian Testingm kernel 4.18/4.19 (both the one from the experimental repos (4.18)...

I did try out the wip kernels a few times but didn't really help as in i did not spot performance differences(whereas newer Mesa did) but the wip kernels...

Mesa 18.2 and kernels 4.18 are working fine. Yes, for better compatibility one should use 4.19 - mainline is fine too (i am using it and works very well)....

[gradinaruvasile]

The desktop Raven Ridge CPUs are stable under 4.18/4.19 at least under Debian Testing and MATE with MESA from git (or Debian Experimental). But your laptop...

But do they actually work? For UVD play something HD with h264 in mpv/smplayer and see the console output. For vce you could try transcoding with ffmpeg:...

What i'm saying that on Linux the cpu and gpu drivers are separate for cpus that don't have iGPs (unlike Windows where you get an AMD ginormous driver...

[gradinaruvasile]

This forum is for Xorg graphical drivers. Ryzen CPUs without iGPs don't use this driver at all. Frequency scaling is a different matter altogether....

Is that a 2200g?? What kernel?

I have on my 2200g (disregard the governor):

analyzing CPU 3:
  driver: acpi-cpufreq

[gradinaruvasile]

Actually the mainline kernel git is just fine. I use it and it works just fine. Mesa the same, the newer the better. 18.2 git for example brings (between...

[gradinaruvasile]

Umm. Since then i restarted the computer and just checked it and works...
The interesting thing is that now vaapi seems to me it is directly used,...

[gradinaruvasile]

I have a Ryzen 3 2200G apu, Debian Testing and with the Mesa 18.0.1 from Debian Experimental i have VDPAU and VAAPI working (although no VP9 and HEVC...

[gradinaruvasile]

Here it doesn't really matter where the dpms support comes from. The driver crashes when tries to manage the dpms on/off setting. Created a bug for i...

[gradinaruvasile]

In Debian/MATE at least the DPMS is commanded by the power manager. If i set the screen to never turn off in the power manager, it will obey that setting....
