No, I don't use powerd. I want my processor to always run at max speed.
But I encountered situations when sometime system is running at 1200GHz instead
of 2400 and it is fixed with BIOS updates.
That is why I check dev.cpu.0.freq each time system reboot.


My processor is Intel E5620 :
http://ark.intel.com/products/47925/Intel-Xeon-Processor-E5620-12M-Cache-2_40-GHz-5_86-GTs-Intel-QPI

It is not so ancient thing.

No, it's not ancient. With no capabilities that can set or report  CPU
frequency, the OID is undefined.

I may be that the "CPU supports Enhanced Speedstep, but is not
recognized."
is really a problem. It says that FreeBSD does not have a table of the EST
setting/energy saving values for that processor. This is not unusual as
Intel at some point decided that these tables were proprietary and stopped
releasing them to the open source community. ACPI should be able to provide
the list of frequencies but it looks like it did not do so. This may be a
bug in BIOS.

Do you see similar messages for all est devices? I am guessing that they
do, but your message does not actually say so.

In any case, the problem is that EST is not attaching and that is cause of
the lack of the OID when P4TCC and throttling are disabled. Since you are
only using it to be sure that the system is running at full speed and re
not running powerd, there is no reason not to enable P4TCC so the OID will
be defined. TCC will not actually be used, so this is the simple solution.

I am concerned that there is now a second report of this, though. It smells
like a BIOS issue,but it seems to work under Windows. Perhaps you need a
BIOS update? (N.B. This is really grasping at straws as I just don't know
much beyond what I have said.)

The parent should probably be listed.  On mine it's acpi0

Right, so even with p4tcc enabled there's no dev.est, yet we then have 
dev.cpu.0.freq and freq_levels made available.  Hmm ..

The above all seem the same, except temperatures.  The only difference I 
see is the lack of dev.cpu.0.freq and dev.cpu.0.freq_levels.

Do you have Enhanced Speedstep (EST), disabled in your BIOS settings?  
If so, just turn it on.  Then you should also be able to set running 
frequency to 'MAX performance' or similar there.

If not disabled, ie you have EST enabled in BIOS, that points to a real 
issue of EST detection.  And it still seems strange that enabling p4tcc 
is enough to have cpufreq(4) include OIDs for freq and freq_levels?

Right, this is still looking like you have EST disabled in BIOS.

Setting debug.cpufreq.lowest=2400 should also accomplish that without 
running powerd.  Enabling higher C-states (C2, C3 .. Cmax) would save a 
lot of power (ie, heat) without compromising performance, but that's a 
separate issue.

Well, your checking did expose this issue ..

Right.  Looks like your board has two of these packages, and indeed it 
does support EST.  If you do have that enabled, we have a problem, and 
really need to see a verbose boot dmesg.  If not, you have a problem 
that can be easily fixed in BIOS settings :)
