--- Comment #4 from Ralf Kölmel ---
Hi,
for completeness please provide also these infos, maybe to see if there are
some odd configurations:
cat /sys/devices/system/cpu/intel_pstate/
max_perf_pct min_perf_pct no_turbo num_pstates turbo_pct
I'm assuming that you have no special kernel parameters set ?
On my system, which don't show this problem, it looks like :
cat /sys/devices/system/cpu/intel_pstate/max_perf_pct
100
cat /sys/devices/system/cpu/intel_pstate/min_perf_pct
31
cat /sys/devices/system/cpu/intel_pstate/num_pstates
27
cat /sys/devices/system/cpu/intel_pstate/no_turbo
0
cat /sys/devices/system/cpu/intel_pstate/turbo_pct
4
The reference explanation (also for the correlation of intel_pstate with
cpufreq) you can find on
https://www.kernel.org/doc/Documentation/cpu-freq/intel-pstate.txt .
One thing i should mention for my systems, that i use tuned to set a cpu/energy
profile.
This isn't the default for a clean installation.
