Hi,
From ??ondemand?? governor source code, you can find its cpu frequency
scaling is for each CPU. OK, now, for multi-core, it should means
unified freq(max freq) for multi-cores ? or varied freq for each core?
We all know many intel platform only support freq/voltage scaling for
CPU, not every cores. So, in Linux /sys, it means the cpufreq doesn't
show real freq for each core?
Does anybody know the issue ?
yep this is very well known.
if you use powertop 2.0 beta it'll calculate the actual behavior ...
