Issues with CPU frequency after upgrade 23.01

bingo600

So "In plain english" , 23.05 has the 23.01 issue fixed.
And i should delete my "tunables", and give it a try ??
Correct ?

Should i enable PowerD , that i use to have enabled to activate the 23.05 speed/power adapt ?

Btw: The PR you listed above, has 23.09 as target

No, 23.05 behaves the same as 23.01 with regard to SpeedShift.

Enabling SpeedStep (powerd) does nothing unless you disable SpeedShift. You can do that by setting hint.hwpstate_intel.0.disabled="1".

Since SpeedShift is better that SpeedStep in every way except the default values (IMO). I recommend just setting the values as you have in both 23.01 and 23.05.

He..he

I just deleted my SpeedShift entries , as i thought the fix were in 23.05.
I'm reentering and setting to 75, as when it ran on 23.01
And keep PowerD disabled.

Thnx

For reference I'm running those values at 80 on a test box I have here that supports SpeedShift.

bingo600

I seem to remember that 80 was the "recommended value" in our last round of SpeedStep settings.

But i like the way my Hystou/Protecli behaves on 75.

I have an Atom C3558, I'm now using pfSense 2.7 but the FreeBSD version is obviously the same. The CPU was running most of the time at 800MHz, now is mostly stuck at the top speed of 2.2GHz and of course runs hotter. I don't know if it's an Heisenberg situation - just having the Dashboard open to check the CPU speed runs the CPU faster.

I have tried to set dev.hwpstate_intel.X.epp to 80 (X from 0 to 3) but it does not help. I'm not sure if the C3558 has SpeedShift, Intel ARK doesn't say it, nor I can find it in the boot log.

C3K doesn't have Speed Shift. Without the dashboard open try running:

Check the available freq levels and current freq shown.

I see this on my Protectli with a (non-Speed Shift?) J3160 with my busy Dashboard and powerd set to Hiadaptive. I never see the current CPU speed displayed at all on the Dashboard (since it's not displayed when at maximum), but if I leave the Dashboard and run sysctl dev.cpu.0.freq at the command line I can see the frequency change.

Tried via SSH - looks locked at 2200MHz:

I'll try to disable SpeedShift and reactivate PowerD and see what happens.

reactivate PowerD

PowerD works fine on the 6100 which is that CPU.

stephenw10

Yeah you need powerd active to get lower CPU frequencies.

@stephenw10

Setting hint.hwpstate_intel.0.disabled to 1 with PowerD returned to the old behaviour:

dev.cpu.0.temperature: 39.0C

So, I added 4 cpu entries for my Intel i3-6100T as described here and seems to work well. My cpu drops down to 897MHz and temps are down to 30 degrees C. PowerD had no effect so I turned it off. I could not tell a difference between 75 and 80 in my low so I left it at 80. My low was never lower than 897MHz.
