option - seems like
it saves quite some power. Does it affect realtime performance. can it
be disabled at runtime?
Should not affect realtime performance - it was judged stable enough
for mainline and I've seen no reports on LKML of it causing problems.
PPS. i've usually disabled freq. scaling during
audio-work as there were
x-runs when the cpu speed changed. this does no longer seem to be the
case.. is it still a good habit to shut down powernowd ?
JACK was fixed to use gettimeofday() as the clock source so disabling
frequency scaling should no longer be needed.
