Available is not required. Set it to C8. That guarantees that you will use
the lowest available. The correct incantation in rc.conf is "Cmax".
performance_cx_lowest="Cmax"
economy_cx_lowest="Cmax"

But, unless you want laggy performance, you will probably also want:
hint.p4tcc.0.disabled=1
hint.acpi_throttle.0.disabled=1
in /boot/loader.conf. Low Cx states and TCC/throttling simply don't mix
well and TCC is not effective, as mentioned earlier in this thread.
