Re: BIOS disables CPUSs.
It would be good to verify that 2.4.21 still works properly on this box
to verify the hardware isn't hosed.  Also, if your BIOS CMOS has error
logs, it might be good to read them to see what it is thinking.

Also, does the same 3-cpu configuration result when you boot 2.6?

Thanks,

It does work fine with 2.4.21, the last part of the log on the mentioned
URL is few hours old.  The hardware looks okay, the box was running for
more than 14 months without any hardware trouble.

> logs, it might be good to read them to see what it is thinking.

I could not find any error logs till now, the BIOS help only says that a
CPU is turned off when a severe error occured.

> Also, does the same 3-cpu configuration result when you boot 2.6?

I cannot promise when I have a chance to test 2.6 there, it's a
production system.

Please try CONFIG_NR_CPUS=8, or apply the patch below to 2.4.23.

smp_boot_cpus() incorrectly assumes that Local APIC ID's are handed out
0,1,2...

But they're handed out 0,1,6,7 on your system.  #6 happens to be your
boot CPU, smp_boot_cpus() brings up #0 and #1, and never asks to boot #7
-- thus 3 logical processors.  If #0 happened to be your boot processor,
you'd get only 2 logical processors.

cheers,

A similar (but more elaborate) fix is in 2.6.

Why is the additional variable "kicked" in 2.6 necessary?
Appears that kicked == (cpucount + 1), and the loop already
compares that to NR_CPUS via max_cpus:

                if (max_cpus <= cpucount+1)
                        continue;

Though I think it would read more clearly this way:

                if (cpucount + 1 >= max_cpus)
                        break;

Speaking of max_cpus, it would probably be a good thing if maxcpus() did
not allow the administrator to set max_cpus > NR_CPUS at boot time.

There's some kind of shenanigan going on with cpucount I can't be arsed
to decipher where it's incremented and decremented all over the place;
do_boot_cpu() returns status, so counting successes got the bug fixed.
Fixing max_cpus > NR_CPUS has some kind of core impact. So I've pretty
much punted on both killing kicked and fixing max_cpus. I anticipate
a particular someone I don't want to hear from complaining loudly.

Maybe something like the below (untested) would be helpful.


-- wli


Propagate kicked down to do_boot_cpu() and nuke the redundant cpucount.
The choice of which to nuke was based on cpucount being modified all
over the place and actually being 1 less than all cpus, vs. kicked being
a counter maintained all in one place and actually representing the
total number of cpus. Old semantics are AFAICT preserved apart from
terminating the wakeup loop at kicked < max(NR_CPUS, max_cpus), which is
actually a darn good idea since there's no reason to fiddle with the
rest of the APIC ID space once we've got all the cpus we're allowed to.

[-- Attachment #1: Type: text/plain, Size: 707 bytes --]

Alles,

I have a new P4 Hyperthreading PC that I have installed RedHat9 on. I am
trying to add some features to my kernel (e.g. NTFS read support, crypto
api, etc.) but when I build my new 2.4.22 kernel with CONFIG_SMP=y set
then reboot, I am seeing only one processor in /proc/cpuinfo. When I
boot with my stock RH9 2.4.20-20.9smp kernel I see two virtual
processors show up in /proc/cpuinfo.

I've even build a 2.4.22 kernel with the config-2.4.20-20.9smp
configuration that came with RH9.

I build with the straightforward 'make dep clean bzImage modules
modules_install' command. Is this correct?

Am I missing a step to build a smp kernel for hyper threading?

Your help would be most appreciated.

Job

I see a very similar behaviour on a dual Xeon system here. But it began
with 2.4.22. After upgrading from 2.4.21 to 2.4.22, HT was disabled. It
became even worse, the mainboard (some Serverworks board in Siemends
Primergy F250 server) decided to disable the second CPU completely (I
don't have the logs from that moment, sorry).

After upgrading to 2.4.23-pre9 and enabling the second CPU in the
mainboard BIOS, I see HT only working on the second CPU. There only a
message about the first: WARNING: No sibling found for CPU 0. I tried
compiling with or without ACPI, it makes no difference. I can live with
3 virtual CPUs but idealy it should be fixed before 2.4.23 release.
Needles to say that it still works with 4 virtual CPUs using 2.4.21.

The problem is still reproducible with 2.4.23-rc3. And the box has
rebooted suddently after 10 days running 2.4.23-pre9 in the weird 1+2xHT
mode. After the reboot, the second CPU disappeared and now I saw that
the BIOS disabled both CPUs, maybe because of detected errors.

Both logs from 2.4.23-pre and 2.4.21 can be found on:
