Hi,
what exactly is the effect of enabling "power save mode" on multi-core

As far as I understood from [1], it only affects systems with more
than one multi-core physical CPU. Does it have any effect on a system
with one dual-core CPU?
nope.
And in theory (!) powertop will only suggest it for multi-physical
cpus.. in practice there seems to be a bug in the detection for this ;)
