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 Name                                 OpenCL ICD Loader
  ICD loader Vendor                               OCL Icd free software
  ICD loader Version                              2.2.12
  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! :-)
