Set it to the lowest available Cx state that you see in dev.cpu.0 .
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.
Is there any reason that TCC is on by default, actually? It seems like
an anti-feature.
