2.3 and PowerD

l3lu3

Prior to 2.3, I've been using powerd with zero problems. After the update, I spotted the following message in the logs:

rc.bootup: The command '/usr/sbin/powerd -b hadp -a hadp -n hadp' returned exit code '69', the output was 'powerd: no cpufreq(4) support -- aborting: No such file or directory'

A quick search didn't show anyone else with pfSense having this problem. I did find an older post on the FreeBSD forums for 10.2, but unsure how relevant it is to this case: https://forums.freebsd.org/threads/52827/

I believe that there are some Pentium4 2.80 Ghz CPUs that support intel Enhanced Speed Step that are in a LGA775 package but I don't think the earlier designs did. I'm not certain if they all supported thermal monitoring either.

If your cpu has Enhanced SpeedStep and thermal monitoring you should have these lines in the dmesg output:

est0: <enhanced speedstep="" frequency="" control=""> on cpu0
p4tcc0: <cpu frequency="" thermal="" control=""> on cpu0</cpu></enhanced>

I can't remember what the prior cpu frequency scaling system was called, perhaps it was just SpeedStep. Manufacturers did things differently and BIOS was often cludged to get it working in Windows and nothing else. If you haven't recently ruined your working ACPI with a BIOS update that contains a broken DSDT (Differentiated System Description Table) or SSDT (Secondary Description Table), I think that it is probably a kernel, kernel module, or module config problem.

To list the kernel modules on your system use:

ls /boot/kernel | grep -v kernel

For future reference, I found the answer, apparently in 10.3, device.hints automatically disabled the options to enable powerd on this cpu platform. The way to turn it back on is to change the following options in /boot/device.hints:

hint.acpi_throttle.0.disabled="0"
hint.p4tcc.0.disabled="0"

but after reading https://groups.google.com/forum/#!topic/fa.freebsd.stable/1eY514QprJY, it seems like it might be a moot point in running powerd at all, as far as power consumption goes.

I've got a PC Engines APU with an AMD G-T40E embedded CPU which also lost cpufreq/powerd functionality by default. I also noticed that the CPU never enters a lower C-state than C1 (don't know if it ever did before 2.3).

So I added hint.acpi_throttle.0.disabled="0" to /boot/loader.conf.local and set hw.acpi.cpu.cx_lowest to C2 in System / Advanced / System Tunables.

Now I get dev.cpu.0.freq_levels again, and dev.cpu.0.freq shows the powerd HiAdaptive throttling and dev.cpu.0.cx_usage tells me about half of the time is spent in C2.


: sysctl dev.cpu.0
dev.cpu.0.temperature: 59.5C
dev.cpu.0.cx_usage: 48.33% 51.66% last 204us
dev.cpu.0.cx_lowest: C2
dev.cpu.0.cx_supported: C1/1/0 C2/2/100
dev.cpu.0.freq_levels: 1000/-1 875/-1 750/-1 625/-1 500/-1 375/-1 250/-1 125/-1
dev.cpu.0.freq: 125

But the CPU temperature is about the same so I suspect I'm trading latency for nothing in return.

ACPI throttling / P4TCC don't actually reduce the clock frequency; instead, they just insert idle cycles into the pipeline. This limits peak power, but usually increases average power, as it keeps the CPU awake for longer. You should remove the hint.acpi_throttle.0.disable line and just use hw.acpi.cx_lowest=C2.
