Phoronix: Some Fresh Linux 4.8 + Mesa 12.1-dev OpenGL Benchmarks For Radeon GPUs

For those craving some fresh Mesa Git benchmarks, here are a few OpenGL tests I carried out with some AMD Radeon GPUs when comparing the out-of-the-box Ubuntu 16.04 LTS performance to what's offered currently by Linux 4.8 and Mesa 12.1-dev Git...

I think llvm is borked currently, so take results with a grain of salt

My Ubuntu 16.04 LTS is not 'out-of-the-box', but with xenial-proposed kernel (4.4.0-38-generic), Mesa 12.1 (oibaf PPA) and linux-firmware package from Yakkety (1.161) my RX470 works without problems, even HDMI audio works.

System details shows "Gallium 0.4 on AMD POLARIS10 (DRM 3.2.0 / 4.4.0-38-generic, LLVM 3.9.0)"

I wanted to use 4.8 kernel but I have no HDMI audio

How is that possible? You need DAL for HDMI audio… right?

Did you use the amdgpu-pro kernel driver?

I dont know how, but the audio works. Using 4.6 and 4.8 from Canonical Kernel Team PPA for Yakkety, audio doesnt work.

I used it before, but now I only use Mesa 12.1

Kernel 4.7 or later is required for Polaris AFAIK... either you have no accel, or ubuntu backported amdgpu something or you have some amdgpu-pro leftover or...

To me it sounds like the kernel module is still installed as a normal 4.4 kernel doesn't support polaris and the amdgpu-pro dkms package can be used in combination with stock mesa (git/12.1) without problems.

ubay@pc:~$ dkms status
aziokbd, 1.0.0, 4.4.0-38-generic, x86_64: installed
bbswitch, 0.8, 4.4.0-38-generic, x86_64: installed
virtualbox, 5.0.24, 4.4.0-38-generic, x86_64: installed

I'm sure that AMDGPU-PRO is properly uninstalled, with the command 'amdgpu-pro-uninstall'.

Better check logs, if amdgpu Polaris works with 4.4 kernel then probably Jupiter did the job
