Why does FreeBSD 8.-0 think that my Dell SX260 have "non-unform processors"?
Torfinn Ingolfsen
I just booted my Dell OptiPlex SX260[1] from a usb memory stick with
FreeBSD 8.0-release on it. Part of the dmesg output is:

Why does FreeBSD think that this machine has "non-unform processors?
Ok, the Pentium 4 in it can proably do hyperthreading, but that isn't
much to talk about.
What excatly is non-unform here?

Why is it booting up at half speed? Same in your 7.2-STABLE dmesg.
Something set that way in BIOS? What does 'sysctl dev.cpu' say?

Only spotted a verbose dmesg for 7.2-STABLE there, not for 8.0?

I suppose you have HTT disabled in BIOS?

I don't know, but suspect the detected half CPU speed may be a clue?

I don't know. Since last time, I've upgraded the bios to the latest
(A03) and reset bios to default values - but the problem is still there.
According to the specs, a SX260 supports all Pentium 4 cpus with 400
MHz and 533 MHz FSB (front side bus).

The only setting in bios related to cpu speed are
"normal" and "comaptible". I've tried both - doesn't make a difference.
Now sysctl.dev.cpu says:

Not, I didn't make one that evening. There is one over ther now. :-)

It has one Pentium 4 cpu.
Hyperthreading was disabled in bios, it is enabled now:

My first thought was that perhaps you were running a uniprocessor kernel, but
I checked GENERIC and SMP option is there. My dmesg is a little different:
FreeBSD 8.0-STABLE #16: Sat Dec 19 22:56:44 EST 2009
CPU: Intel(R) Pentium(R) 4 CPU 2.80GHz (2793.02-MHz 686-class CPU)
Origin = "GenuineIntel" Id = 0xf41 Stepping = 1
Features=0xbfebfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CLFLUSH,DTS,ACPI,MMX,FXSR,SSE,SSE2,SS,HTT,TM,PBE>
Features2=0x641d<SSE3,DTES64,MON,DS_CPL,CNXT-ID,CX16,xTPR>
AMD Features=0x20100000<NX,LM>
TSC: P-state invariant
FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs
FreeBSD/SMP: 1 package(s) x 1 core(s) x 2 HTT threads
cpu0 (BSP): APIC ID: 0
cpu1 (AP/HT): APIC ID: 1
I think the clue to run down is why does FreeBSD think your sx260 is running
at 1295.21-MHz.
I think I would try updating your usb stick's kernel with 8-stable and rebuild
it. I'm wondering if someone who made the stick image turned off SMP to make i
fit on small sticks (above is 7.2-stable, not the 8 on a stick).
I see HTT in your CPUs features, but I wonder what that's based on. What if
the BIOS supports hyperthreading but the cpu doesn't? (there were p4
processors sold before hyperthreading came out, I know, I bought one. 8o)
You might try finding a cpu diagnostic tool that describes the cpu in great
detail, like from download.com, etc.
You might also go to Intel's site and lookup the id 0xf29 and see if Intel
says it actually supports hyperthreading.

set to the following by adding:
powerd_enable="YES"
power_flag'-i 85 -r 60 -p 100"
or
Now you can also modify this file: /etc/sysctl.conf or /boot/loader.conf
(CPU Frequency)
debug.cpufreq.lowest=600
To test live in your terminal you can set it with this command:
sysctl debug.cpufreq.lowest=600
Now you can set it to 1200 but I would recommend 100 at a time for testing.

Yes, this is your problem, regarding speed anyway. I only picked up on
this because this year we bought 2 used intel mobos on eBay; a D845GBV
with a 2GHz P4 (also 400/533 MHz FSB with similar 845 chips to yours)
and the other a D865GLC with a 2.6GHz HTT P4 (400/533/800 MHz FSB).
Only the D865GLC 800MHz FSB board takes the 2.6GHz HTT P4, shown as
'2.60C GHz' in the board manual and also on this page:
http://www.intel.com/support/processors/pentium4/sb/CS-011987.htm
Our older 400/533 FSB board only takes a non-HTT P4 using 400MHZ FSB,
('2.60 GHz' without the 'C'), though it only has a 2GHz non-HTT CPU.
After a looong time hunting through fluff and bumph from various angles
and searches on the intel site (argh!), I finally found:
http://processorfinder.intel.com/List.aspx?ProcFam=483
Where there are several 478-pin 2.60GHz P4s with 512MB L2 cache, eg:
http://processorfinder.intel.com/details.aspx?sSpec=SL6WS (800MHz FSB)
http://processorfinder.intel.com/details.aspx?sSpec=SL6QR (400MHz FSB)
but all of the HTT 2.6GHz ones require 800MHz FSB, so I guess this is
why its set to run at half speed by your board? Perhaps the SX270 you
mentioned having taken this CPU out of, supported up to 800MHz FSB?

Yeah, just p4tcc thermal throttling, no EST speedstep control on these;
powerd could save you some heat but not much less power use, I gather.

Well I don't imagine running at half speed with HTT is going to be as
quick as full speed without .. and I'll guess further that this is what
the 'non-uniform processors' message is likely about. You may find that
putting a faster non-HTT P4 in it, maybe up to 2.8GHz would go better,
or that search tool shows some 3.06GHz and a 2.40A GHz HTT @533MHz FSB.

You're right, of course. :-)
I found a Pentium 4 with 400 Mhz FSB, it looks much better now:

Great. Your 2GHz P4 is a later stepping which has HTT also, ours is:
CPU0: Intel(R) Pentium(R) 4 CPU 2.00GHz stepping 04
Total of 1 processors activated (4003.47 BogoMIPS).
as Debian dmesg tells it.
But I still don't know whether it's nowadays safe and/or advantageous
running hyperthreading on these CPUs in FreeBSD? Anyone?
cheers, Ian
