PFSense on a DEC3840 (Netboard A20)

@stephenw10 I tried it Hi-Adaptive and Maximum, both stayed at 1200.

Hmm, I mean there is a possibility that CPU loading never gets high enough to start ramping up. Or that it's not detecting the loading correctly.

Try running:

sysctl -a | grep freq

So you see cpu frequency levels shown?

If so you can try killing powerd and setting the level manually.

@stephenw10 it returns the following:

Would the command to set it manually be " set dev.cpu.0.freq_levels=2100/1890" ?

Ah, OK. Looks like it's working.

Kill the powerd process then:

sysctl dev.cpu.0.freq=1700

Or whichever speed you want.
The second number there is meant to be power consumption in mW. But I've always found it to be somewhat random!

@stephenw10 that command did change the freq in the console:

stephenw10

Then maybe your test simply didn't load up the CPU enough.

bpl294

@stephenw10 So when i do a speed test over a WG interface it spikes the CPU up to 80% when the PowerD is enabled and at 1200mhz and it doesn't increase the freq. Is the CPU spiking that high good enough to say to increase the freq?

stephenw10

Yeah, 80% should be plenty high enough in highadaptive mode.

I would suggest powerd is not accurately reading the loading in that case. I'm not sure there's anything we can do about that.

@stephenw10 It seems as though that powerd isnt able to distinguish the option in its config. Because it is only using the option that i set for "Unknown Power"

This results in the cpu running in hi-adaptive mode. And i did notice the CPU dropped down to 1700 at one point. If i set that to Minimum, then it stays at 1200mhz. I am using the Apcupsd package. Not sure if they are communicating well.

stephenw10

Ah, that's probably OK then. The defaults we yuse are set hiadaptive for all three. It depends what the BIOS is reporting which is not reliable.
Powerd and apcupsd are not connected.
