Powerd no longer works on FreeBSD 14.1 on laptop

N

nickednamed

I recently upgraded from 13.sth to 14.1 and powerd no longer seems to work, and sysctl no longer shows cpu freq_levels.

I'm 99% sure everything was working as expected before. In any case, after the upgrade there is a significant difference in CPU usage, temps, and battery life, on the same hardware, with the same configuration.

Here is some more info:

CPU is Intel i7-2620M

uname -a
Code: 
FreeBSD laptop 14.1-RELEASE-p5 FreeBSD 14.1-RELEASE-p5 GENERIC amd64

When trying to run powerd, either from /etc/rc.conf or command line, I get:
Code: 
powerd: no cpufreq(4) support -- aborting: No such file or directory

sysctl dev.cpu.0:

Note, cpu_freq is no longer listed, as it was before.

FWIW, it works on "11th Gen Intel(R) Core(TM) i7-1185G7 (8) @ 4.80 GHz"
