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 :-)

ICD loader properties

ICD loader Profile OpenCL 2.2
NOTE: your OpenCL library declares to support OpenCL 2.2,
but it seems to support up to OpenCL 2.1 only.
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! :-)
