But which ones are NUMA with node-scattered physical memory? sn2 for sure. DIG, zx1 are not, for sure. I'm not certain about NEC or Bull. So I'm not convinced that it works for all possible physical memory layouts. Jesse> So you're worried about the performance penalty of turning on NUMA for Jesse> generic kernels? Yes. Actually, I'm concerned about size, too. It would be good to have an init-mem-like approach so that we can free all the code/data for unused machvec code. --david
