Well you have to do a lot more work then to handle instable TSCs then. In particular the frequencies can be different between CPUs, they change (which you can catch with cpufreq notifiers) and during the cpufreq change period they're instable (as in you can't tell for some time which frequency they're currently running at and they might be running immediate frequencies) The current cycles_2_ns() users avoid this problem by not using the TSC in this case, but that might not be an option for you (cpufreq is becoming more and more ubiquitous) Good luck. -Andi - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
