I used AMD pro stack for sometime before the AMDGPU driver evolved to something useful.

Not all of the patches are upstream, but they are all public. Is the opensource driver you're thinking of at the url that harry gave me? What it the state? (beta, alpha, etc.). About how complete is it with respect to the other opensource GCN drivers? > OpenCL support is provided by the ROCm stack which you can get from the > gpuopen site. "We do not support ROCm with PCIe Gen 2 enabled CPUs such as the AMD Opteron, Phenom, Phenom II, Athlon, Athlon X2, Athlon II and Older Intel Xeon and Intel Core Architecture and Pentium CPUs." Ouch! Mine is a Phenom II 6 core 1090T. I can't go spending a ton on a new CPU, MB, RAM, and GPU (and I'd need a less hacked case too :) Granted I could get an i3, cheap the MB and RAM, but I've worked so hard for a great platform... 32GB RAM, 6 core Phenom II, HD 7780 GPU, RAID 5 on 2TB HDs, Bluray drive, Mechanical keyboard, HP laser printer, 4800x4800dpi HP scanner... AMD is normally so good at compatibility too. Ok, I'm over it, what is doable at this point? > Headless boards are supported just fine and have been > for years.

[1] No offence, but AMD's gpu-pro would not allow the system to suspend (sleep), also I'd often get a black and white set of vertical lines through my display and the kernel would totally freeze (no sysreq). The worst part is that it would happen totally randomly (really).
