Comment(by sandeen):
I tried running w/ this patch (ran powertop, built libmyth, stopped
everything, copied over original, ldconfig, started everything, ran
powertop again) and didn't see any difference:
before:
{{{
Wakeups-from-idle per second : 147.2 interval: 15.0s
no ACPI power usage estimate available
Top causes for wakeups:
27.4% ( 80.7) mythfrontend : schedule_timeout (process_timeout)
21.4% ( 62.9) <interrupt> : ivtv0
20.6% ( 60.5) <interrupt> : CMI8738-MC8, nvidia
9.8% ( 28.9) mythbackend : futex_wait (hrtimer_wakeup)
}}}
after:
{{{
Wakeups-from-idle per second : 147.8 interval: 15.0s
no ACPI power usage estimate available
Top causes for wakeups:
27.3% ( 80.8) mythfrontend : schedule_timeout (process_timeout)
21.2% ( 62.8) <interrupt> : ivtv0
20.5% ( 60.6) <interrupt> : CMI8738-MC8, nvidia
9.7% ( 28.7) mythbackend : futex_wait (hrtimer_wakeup)
}}}
but feel free to double check my results :)
