Last I checked, which was quite recently, they were literally not
programmable on Linux whatsoever.  The "issue" is it's completely
unsupported on Linux and does not work at all.

(OpenCL on the normal CPU cores works, mind you, but is embarrassingly
slow compared normal threaded code, so that's useless)

Unfortunately Intel is light years ahead of AMD in most things these
days.  Though, if AMD has CPUs with on-die programmable GPUs in Linux, I
for one would be quite a bit more interested...
