It would be nice to have a /sys file where the CPU frequency is in, but unless you have cpufreq loaded, no such file exists. And there are quite a few processors which do not have cpufreq, so /proc/cpuinfo is the only information (besides dmesg) where you can read it from. -- 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/
