looking through open source components, I'e noticed that amd_kfd driver within linux kernel offers drivers for HSA component to userspace.
I tried that on my Kabini board ( Athlon 5350) only to discover that it currently supports only Kaveri and Carrizzo.
I googled around and found HSA Foundation page with sub-projects, one of them covering linux kernel component, which is, I presume, periodically patched into official kernel sources:
But even that one mentions only Kaveri and Carrizo.
I there a plan for Kabini and some predicted timeline ?
