Fresh Mesa 11.3-devel RadeonSI Tests On Ubuntu 16.04 vs. NVIDIA's 364.19 Driver

... I have R390 and surprisingly, it's closer in performance to 290 than Fury

Why surprisingly?
390 and 290 have the same chip.

I don't know why, but I seem to be getting MUCH better performance with Ubuntu 16.04's Mesa 11.2 than the 11.3 devel version (on R9 290 atleast). Can anyone test on their setup and confirm? Maybe I am just doing something wrong...
Either way, it's great to see Open Source drivers delivering good performance compared to the competition. Hopefully AMD will keep supporting the devs.

Hi, any update on the performance regression? Have you tried to bisect it? Which apps are affected?

If those R9 Fury cards had 8GB of memory I would have got one. Gaming at 4k definitely eats more VRAM, especially when you insert 4k texture mods for games like I do.

You can use it without installing. This video will explain.

When I try to install the benchmark it gives me error: Dependency is not satisfiable: php5-cli

I have php7 installed. Help?

OK, managed to run it. I have R390 and surprisingly, it's closer in performance to 290 than Fury

How did you manage to get past that issue? I have the same issie and would also like to get the bechtool running...

I mean rc5. Xserver hang when starting with 4.5.0 kernel version was fixed with a temp patch and it is permanently fixed from rc3.

Thanks!

For me amdgpu-pro have better fps than mesa in Unigine Heaven. To use, it download latest kernel from kernel.org and enable CIK support and remove unneeded drivers and modules. Google for more info about linux custom kernel. After your amdgpu driver works, you can use amdgpu-pro.

By latest kernel you mean 4.5.2 or 4.6-rc5? Is the issue with CIK support resolved (I mean the one with 4.5.0 kernel)?

Is this the recommended way of bisecting MESA regressions when using a PPA?

Those instructions look reasonable to me. Make sure you test your "good" (11.2) and "bad" (11.3-git) points also after compiling from source, to make sure you didn't accidentally compile with bad flags.

Hi guys,

Could you please bisect the regressions, so that we can fix them?
