I don't know the details in this particular case. However, even if two CPUs are object code compatible, it doesn't mean that instruction scheduling, caching and such things behave the same way. Code optimized for one CPU might not be optimal for another, even if it runs. -- M?ns Rullg?rd mru@users.sf.net - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
