One question is, why are 0-1M frames also copied to high end which are then clobbered immediately? It looks like unnecessary if just for leaving a guard range from stray pointers... move_memory(e, 0, __pa(&_end) - xen_phys_start); /* Poison low 1MB to detect stray pointers to physical 0-1MB. */ memset(maddr_to_bootstrap_virt(e), 0x55, 1U<<20); Thanks, Kevin _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
