Okay, so I have tested on ATI/AMD Radeon XT7870, and clinfo shows some
stuff.. but also gets some error that propagates to upper layer
applications..

I have noticed that when I also install Intel driver for OpenCL there
are errors because there is no underlying hardware. CPU based OpenCL
driver is nice to test some stuff.

It still needs some work but I can see that ATI/AMD really left nVidia
far behind in the Open-Source world.

I have just ordered ATI/AMD RADEON RX 580 :-)

AMD ROX! =)
NVIDIA SUX! =)
