Install pro driver with opencl on Debian Stretch? Also compiler flag quest.

Hello, I am the proud owner of a Rx 580 card and I'm on Debian 9 (stretch)

 

I've been using AMD hardware for my desktops for >20 years - going back to the Rage 128 on my power mac

I'm currently using the open source amdgpu stack via Debian 9 (stable) with backports enabled.

 

However I am getting errors in some programs, for example, Blender, LuxCoreRender, etc.. (output from clinfo is below)

 

I was unable to install the amdgpu-pro driver either, using the supplied script.

Since Ubuntu is based on Debian I figured that this couldn't possibly be that difficult but rather than trying to figure it out myself with possible impact on stability (my machine is more stable now than it had been in a long time) I thought I should ask you first..

 

I'd like to do whatever it takes so that the pro driver is installed, without problems, and openCL and the Blender export tools work.

 

I want to be able to use openCL accelerated rendering to render optically complex materials like glass, clear plastic and water.

 

Can that be done without "breaking Debian" as they say? I am an intermediate level user and can compile software, edit scripts, etc.

 

Also, unrelated, I wanted to ask what the best compiler optimization flag string was for compiling software for Bulldozer. I am still on a Bulldozer machine.

 

Here (below) is the clinfo output as it is returned now.

Thank you!

I am very happy with my purchases, generally. Your products offer excellent value.
