I don't seem to have a `cpuinfo` command. I use OmniOS, if that matters.
That said, after googling for cpuinfo alternatives, I found and run:
# psrinfo -v

Also, running `while true; do kstat -m cpu_info | egrep

vary in time and on the various cores/instances. The only two values
appearing are 2401000000 and 400000000. The displayed chaging Cstate
values , 1, 2, 3
Finally, looking at

Are those commands the proper way to detect if CPU scaling is working?
Thanks.

Does 'cpuinfo -v' return anything?

Hi,
Is there a way to check the current CPU frequency and temperature ?
Do Illumos supports scaling frequency depending on CPU load ?
My (fanless) server is quite hot and I wonder if everything is ok.
Thanks.
PS: In case it depends on CPU, my server is:
# prtdiag -v
