--- Comment #4 from Dirk Brandewie <dirk.brandewie@gmail.com> ---
I looks like everything is working correctly.  You have to remember that the 
frequencies returned by turbostat and intel_pstate are measured effective
frequency over the time of the sample.  Previously with acpi_cpufreq the value
returned through /proc/cpuinfo and the cupfreq sysfs interface was the
requested
frequency and not the actual frequency.

If you want to see that the floor for P states has actually changed you can see 
the requested P state with:
  rdmsr -a -f15:8 0x199

The actual frequency that all cores on the processor run at is selected by the
processor based on the requests for all cores.
