Description

My problem was, that in the boot logs pfSense did detect and use Intel SpeedShift.
As i have an i3-7100 CPU which, supports Intel SpeedStep, i wanted this to be used for better powersavings.

I´ve spent many days to find out how to enable SpeedStep.
Actually you have to disable the p-states - now the boot log in pfSense shows SpeedStep is found and used.
Now the CPU has much more states for frequency and uses them instead of only the two states from Speedshift.

For this to work I had to add one line to the loader.conf.local:
hint.hwpstate_intel.0.disabled="1"

Would it be possible to include this under "Miscellaneous" as Checkbox. named e.g. disable SpeedShift / enable SpeedStep?
Or maybe add it to the pfSenses documentation?
Or maybe both?

Thanks in advance.
