Clinfo output

Trying to couple mainline amdgpu driver with opencl from amdgpu-pro (installed via Gentoo dev-libs/amdgpu-pro-opencl package). Clinfo and apps see the opencl but when trying to create a command queue driver returns CL_OUT_OF_HOST_MEMORY. (My previous attempts end up with clinfo crash, so it is an obvious progress). The same behavior is reported on Ubuntu 16.04.3 as you may see here https://redmine.darktable.org/issues/11702
