There was a bug in the waitpid logic, a fix for which was committed to the git tree. Please try this again with the new code. Also, you might want to use it as such: sudo idlestat --trace -t 5 -f /tmp/myoutput -- /usr/bin/top (note the --) to ensure that idlestat doesn't get confused about the command being another commandline parameter. > Total trace buffer: 153896 kB > Log is 4.999488 secs long with 675 events > clusterA@state hits total(us) avg(us) min(us) max(us) > C6-SNB 163 4955450.00 30401.53 0.00 141946.00 > cpu0@state hits total(us) avg(us) min(us) max(us) > C1-SNB 1 912.00 912.00 912.00 912.00 > C6-SNB 115 4996270.00 43445.83 67.00 211819.00 > cpu0 wakeups name count > irq040 eth0 50 > cpu1@state hits total(us) avg(us) min(us) max(us) > C1-SNB 3 10809.00 3603.00 27.00 10742.00 > C6-SNB 62 4985746.00 80415.26 59.00 223952.00 > cpu1 wakeups name count > irq018 ata_piix 6 > cpu2@state hits total(us) avg(us) min(us) max(us) > C1-SNB 3 10800.00 3600.00 26.00 10745.00 > C6-SNB 52 4986684.00 95897.77 5724.00 223957.00 > cpu2 wakeups name count > cpu3@state hits total(us) avg(us) min(us) max(us) > C1-SNB 20 15123.00 756.15 121.00 10895.00 > C6-SNB 47 4962591.00 105587.04 1.00 223950.00 > cpu3 wakeups name count > Does that mean processors spent all time in idle state and none in active > state? > > -- > Best Regards > Salman Ahmed > > _______________________________________________ > linaro-dev mailing list > linaro-dev@lists.linaro.org > http://lists.linaro.org/mailman/listinfo/linaro-dev _______________________________________________ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
