Trying The Radeon RX 480 & R9 Fury With The AMDGPU Code For Linux 4.8

With the main batch of Radeon/AMDGPU driver changes ready for DRM-Next that will in turn land for the Linux 4.8 kernel, I've begun testing this new code with various AMD GPUs. Here are my AMDGPU results when comparing Linux 4.7 Git to this code that's coming for Linux 4.8 with a Radeon R9 Fury and RX 480.

Yesterday I built a fresh Ubuntu kernel of this new drm-next-4.8 Radeon/AMDGPU material merged back atop its Linux 4.7 drm-fixes code. This was pointed out by Alex in the forums due to not all of the drm-fixes being mainlined yet for the RX 480. If you are interested in trying out this Linux 4.7 drm-fixes + drm-next-4.8 kernel for Radeon/AMDGPU, you can find it on Phoronix.net: linux-image-4.7.0-rc5-4.8-next-plus-fixes_4.7.0-rc5-4.8-next-plus-fixes-1_amd64.deb.

I compared this 4.8 DRM-Next code to Linux 4.7 Git mainline for seeing if there are any OpenGL performance changes for the R9 Fury or RX 480...

See yesterday's article for the new features/changes of AMDGPU for Linux 4.8. Mesa 12.1-dev from the Padoka PPA was running on this system.




But long story short, there weren't any OpenGL performance changes found for the R9 Fury or RX 480 with this DRM-Next code. You can dig through more data via this OpenBenchmarking.org result file. At least the AMDGPU Linux 4.8 code is bringing the OverDrive overclocking support, so will get some RX 480 Linux overclocking results up shortly.
