idle=poll is handy when profiling the kernel with oprofile clock-unhalted events. Because if you use the normal halt-based idle loop no profile "ticks" are accounted to idle time at all and the results are really hard to understand. - 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/
