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? The GPU 
of particular interest to me is Radeon HD 8470, caicos, which appears to 
have WIP:

How can one help move this forward?
