Hi,
I have a few questions about the PM Dual Core and how could it really work
with Linux. Sorry if there are new patches on LKML about any of these things:
Could each processor or die, have it's own cpufreq scaling governor?
Is there a way to allow one die to be idle and let the other one normal?
So in other words, could we manage these processors speedstep, utilization and
workload individually?
This depends on your hardware. I was reading the Sossaman data sheet the
other day, and it says that the entire chip must run at the same
frequency. You can set each core to a different frequency, but the
hardware chooses the higher of the two. Likewise, the entire chip can
sleep, but individual cores can only go into C1. I imagine the Core Duo
is the same.
IIRC, the dual-core Opterons behave a little differently but the two
cores still have to run at the same frequency.
