Working AMD VEGA 56 based graphics card

[Andreas Drewke]

Hi,

I am the author of a 3D engine and am currently working on a game title. 
I use FreeBSD as main operating system for that.

Please see here if interested: https://github.com/andreasdr/tdme2

I started with a NVIDIA 1060 graphics card using the binary driver from 
NVIDIA. This worked great but did not include a working vulkan API.

So I bought a AMD VEGA 56 based graphics card for that. A nice side 
effect is that I can use now a open source graphics driver (amdgpu).

I can confirm that hardware accelerated OpenGL and Vulkan does work with 
FreeBSD using AMDGPU. (My Vulkan renderer is not complete yet, but shows 
content as expected in comparision to NVIDIA on XUbuntu)

Please see attached the required text files.

I am writing this because I was hinted to do so in #freebsd IRC channel. 
If you want me to do some further tests just tell me.

Best regards
Andreas
