I have question about tlb flush. When a memory page is unmaped, do we always flush tlb of all other cores? Or do we have some way to track which core to flush? If so, how do we track that information? And it would be better if some one can show the code in the kernel to do that.
Please look for active_tlb() in Context and global_flush() in map_util.cpp where the flush is done according to the active_tlb mask.
