I did not find anything that looks like configuring the C-states. You can just enable/disable the HPET timer, the ACPI wake states (S1 or S3) and other settings that are not related to ACPI/frequency scaling like configuring the USB ports. It looks like FreeBSD also doesn't detect the settings well: http://lists.freebsd.org/pipermail/freebsd-acpi/2011-August/007264.html I guess there is no chance to get C3 states working. I looked into the manual [1] and on page 28ff the table lists the expected power consumption when the system is in various states. I did not see any C3 state there, only C1. So I guess I have to use this board with the limitation or think about changing to a board that supports frequency scaling. Thanks for your support.

Re: frequency scaling on D525MW not working properly
Also on the D5* atoms on FreeBSD it would be nice to check that it actually works as advertised, by running a few cpu-bound processes (i.e. for (;;); ) and measuring the watts being burned at different frequencies. That's the real proof that the frequency scaling is doing something real. -Matt

Thanks for the details. I did not look at that point as I expected at least frequency scaling which is supported by the Atom on the Fit-PC2 I also use. I think I will try to get the temperature down by using a fan. But then it is no longer a fanless system that I wanted to have running all the time. And a system in a mini-ITX case with a temperature of 55 degrees is not what I want to have running all the time. Thanks all for the help. I guess I will have to think about a replacement to get a cooler fanless system. Regards, Sven

Hmm, disabling UEFI is OK, but make sure that you have enabled EST in BIOS (something probably read like "enhanced speed step" or something like "P-state"). Besides CPU P-State, you could also set allowable CPU C-State to C3 by setting sysctl hw.acpi.cpu.cx_lowest and put tunable hw.i8254.intr_disable="0" in /boot/loader.conf (you need to reboot after changing /boot/loader.conf).

frequency scaling on D525MW not working properly
Hello, I bought an Atom based Intel D525MW board. DragonFly release is running on that system. But I have a few minor issues. The CPU is getting somewhat warm (about 55 degrees celsius). This is not a real problem, because it is not too hot. But I think this occurs because the frequency scaling does not work. Running "sysctl hw.acpi" prints the following lines (I cut the output to one logical CPU, but for the other three the output is identical): hw.acpi.cpu.cx_lowest: C1 hw.acpi.cpu0.cx_supported: C1/3 hw.acpi.cpu0.cx_lowest: C1 hw.acpi.cpu0.cx_usage: 100.00% last 5000us Also there is no sysctl hw.acpi.cpu.px_dom0.select available, so I guess powerd is also running not properly and the CPU frequency is not scaled in any way. After looking into the dmesg output, I guess some driver does not recognize parts of the hardware/ACPI stuff correctly (see below; the text is repeated for the other 3 logical CPUs). cpu0: on acpi0 cpu_cst0: on cpu0 cpu_pst0: Can't get _PSS package - AE_NOT_FOUND The dmesg is attached. It would be great if there is someone who can help me to get this fixed. If more details are necessary, just let me know. Sven Copyright (c) 2003-2012 The DragonFly Project.
