So the only constraint is that when a 64b naturally-aligned access is made to mtime/mtimecmp, the access must be completed atomically if the platform allows 64b naturally-aligned accesses to those registers? A platform is still allowed to signal an error on such accesses and to force an RV64 processor to access those registers with 32b loads and stores, right? Cheers, David
