Just to conclude: NVIDIA SUX - just as most of you stated no support from nVidia to Open-Source and more interesting OpenCL applications of their GPU - after almost 15 years of being loyal customer (purchased 5+ cards and recommended to others) I say GOODBYE NVIDIA WILL NOT RECOMMEND YOU TO ANYONE ANYMORE! ATI/AMD RADEON ROX - I have just bought RADEON RX 580 and OpenCL seems available here - HELLO AMD RADEON - you have just re-gained old customer I missed your smooth edges and better colors :-) #

Segmentation fault (core dumped) <--- ;-) Except DRM and AMDGPU firmware it still needs some more tweaking, but this is clearly a proof of hardware vendor support for Open-Source Community :-) "It's not Open-Source if not runs on FreeBSD"^TM :-) Thank you folks! :-) Tomek -- CeDeROM, SQ7MHZ, http://www.tomek.cedro.info
