Hi Eric, I got the following report from PowerTOP after cyclic event was added.
=====snip====== Wakeups-from-idle per second: 392.5 interval: 5.0s Top causes for wakeups: 25.5% (100.1) <kernel> :unix`cbe_hres_tick 25.5% (100.1) <kernel> :genunix`clock 25.5% (100.1) <kernel> :genunix`cyclic_timer 19.1% ( 74.9) <kernel> :uhci`uhci_handle_root_hub_status_change 8.5% ( 33.4) <kernel> :ehci`ehci_handle_root_hub_status_change 8.4% ( 33.0) java :<scheduled timeout expiration> 2.5% ( 10.0) <kernel> :ata`ghd_timeout 1.5% ( 5.8) dtgreet :<scheduled timeout expiration> 1.0% ( 4.0) <kernel> :genunix`deadman ======snip===== This looks confused for me. Actually, timer interrupt occurred 100 times per second, from the report, We know we have 3 cyclic consumers, but it appears we have 300 times events. >>>>>>25.5% (100.1) <kernel> :unix`cbe_hres_tick <<<<<<<<<<<<< >>>>>>25.5% (100.1) <kernel> :genunix`clock <<<<<<<<<<<<< >>>>>>25.5% (100.1) <kernel> :genunix`cyclic_timer<<<<<<<<<<<<< This is probably wrong. Thoughts? Thanks, -Aubrey
