if your system is idle, C0 residency should < 10%. Here C0 = 32.7%, there must be a workload on the system. > > Wakeups-from-idle per second: 1156.3 interval: 5.2s > Power usage (ACPI estimate): 2.737W (discharging: 0.6 hours) > > Top causes for wakeups: > 19.3% (223.2) <kernel> : genunix`cv_wakeup > 8.6% (100.0) <kernel> : genunix`clock Apparantly, clock should be the top cause for wakeups, not cv_wakeup if your system is in idle. > 4.0% ( 46.3) <interrupt> : i915#0 > 3.5% ( 40.8) sched : <cross calls> > 3.2% ( 36.9) <interrupt> : i8042#0 > 1.9% ( 21.9) <interrupt> : wpi#0 > 1.7% ( 19.2) <kernel> : > uhci`uhci_handle_root_hub_status_change > > > > Q - Quit R - Refresh > > I have cpupm and cpu-threshold setup...it used to work on my Travelmate > 5720, not any more after svn111.. You can check the system by "mpstat" or "vmstat" or "prstat" to see the cpu utilization and what is using CPU. -Aubrey _______________________________________________ indiana-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/indiana-discuss
