I note that in FreeBSD 11, we now have this:
# grep performance_cx_lowest /etc/defaults/rc.conf
performance_cx_lowest="C2" # Online CPU idle state
However this wiki page suggests that C1 is the default
https://wiki.freebsd.org/TuningPowerConsumption
Are these inconsistent?
I went looking for this because I've been having trouble with the TSC-low
timecounter hardware choice and my system clock running at about 80% of normal
speed. Moving to ACPI-fast solved this problem.
Could the power saving CPU states be related to this problem, or should I look
elsewhere for the TSC issue?
This is a server, not a laptop.
Thanks
