I did something new for me recently. I installed FreeBSD 14.3 on a used Dell PowerEdge T430. It features dual Intel Xeon E5-2683 v4 processors, 160GB of ECC RAM, a flashed Dell PERC H330 RAID card, a Kingston KC600 256GB SATA SSD, 8 Seagate Ironwolf 4TB NAS HDDs and so on. (I've attached the...

So, as might have been obvious from an answer in another post I'm trying to help a little with restoring and improving the BeagleBone Black & possiblye other TI processors support. One of the things that I've been wanting to have ever since using FreeBSD (on the BBB) is dynamic frequency &...

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...

sysctl -a | grep dev.cpu.* shows freq_levels for only cpu.0 even freq is also being shown for dev.cpu.0 why is this happening?

How to get CPU turbo frequency? I want to write small statusbar widget in C which will show current CPU frequency (including turbo). For example I can (in shell) run sysctl -n dev.cpu.0.freq and that return maximal base frequency (or in Intel case: max base frequency + 1 MHz). To get turbo freq...
