[Bug 370333] Re: Regression: Kubuntu 9.04 generates 25 wakeups/s in powertop

[Alan Jenkins]

And the differences are:

  24.6% (  7.4)     <kernel core> : hrtimer_start (tick_sched_timer)
(but these wakeups are most likely duplicates of the hi-res timeouts below. otherwise there would be closer to 17 extra wakeups instead of 10)

  14.7% (  4.4)         konqueror : schedule_hrtimeout_range (hrtimer_wakeup)
  10.0% (  3.0)          knotify4 : schedule_hrtimeout_range (hrtimer_wakeup)
   3.6% (  1.1)              kwin : schedule_hrtimeout_range (hrtimer_wakeup)

   3.3% (  1.0)              Xorg : queue_delayed_work (delayed_work_timer_fn)
(delayed_work looks more kernel-specific.  Maybe Intel KMS, I dunno.)

   3.3% (  1.0)   hald-addon-stor : schedule_hrtimeout_range (hrtimer_wakeup)
(is present in 8.04, but only at _0.5_ wakeups/s)

   0.9% (  0.3)            plasma : schedule_hrtimeout_range (hrtimer_wakeup)
   0.7% (  0.2)             kded4 : schedule_hrtimeout_range (hrtimer_wakeup)
   0.7% (  0.2)           krunner : schedule_hrtimeout_range (hrtimer_wakeup)
   0.7% (  0.2)          knotify4 : futex_wait (hrtimer_wakeup)
