Hi, Is there likely to be support for OpenCL on older AMD GPUs? I have tried running an OpenCL benchmark (https://github.com/mpicbg-scicomp/gearshifft) on an AMD A6-6420K APU running Fedora 28. The code seems to partially run, but gives incorrect results. Would it be challenging to add full OpenCL 1.1 support? Benson
