Those are\nmostly expected to run on server-class machines. The Thunder familly\nof CPUs are just meant for those kind of server-class machines.\n\nSo I do see a direct use-case for adding the ThunderX familly of cores,\nyes.\n\nFor the others, I'm not as positive, but I still added them while I was\nat it. Not much additional work, except waiting for more tests to run...\n;-)\n\nRegards,\nYann E.
