Depending upon the loop calibration method used by a particular architecture it can me one of many different things. Some platforms don't even make use of it and thus leave it at it's default value of "1<<12", so using it as a heuristic here is arbitrary at best. -- 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/ | |||||||||
