Does it means that a timer-based delay implementation must be used to get an accurate delay in SMP. I think it should print a warning message if the CPU delay loop is used in SMP. In my system, the wrong delay interval fluctuated with CPU frequencies caused a control problem. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
