SMP

[Guillaume Laurhs]

Hello 2 All,

I recently bought a Daystar nPower card to bless an old 9500/132 (it's
now a bi-180). I successfully compiled on it an smp kernel.org 2.2.16
kernel on it, and it works flawlessly... but with only one cpu...

pm9500:~# cat /proc/version
Linux version 2.2.16 (root@pm9500) (gcc version 2.95.2 20000313 (Debian
GNU/Linux)) #2 SMP Mon Jun 12 16:59:05 CEST 2000

I know that smp in an unsupported feature, but would somebody help
me/provide me links or people to activate it ??

Thanks,

GoM

You can get a working SMP kernel at ftp://borg.mit.edu/pub/linux/linuxppc/kerne
ls/multiprocessor/ with all of its support files.  It's a bit old (2.2.12),
but it works.

Weren't those cards the only working example of assymetric
multi-processing?.  Would an SMP kernel actually drive them properly?

Hi *,

yeah it works on a UMAX S900, but without USB.

Unfortunately, it doesn't work. BootX 1.2.2 shows up only one penguin, and I get
the same /proc/cpuinfo.
I realized that I have this oddity in dmesg :

Entering SMP Mode...
Processor 1 is stuck.

On 2.2.16 it's the same (dmesg from the begining) :

It sounds like the second processor cannot be correctly started...

I tried with an older bootX (1.1.3) it's the same. For now, I can't quik, I think
Darwin messes up quik (it's installed on a partition before linux).

The cards work well under MacOS, distributed.net client makes a full use of both
processors (which brings the 9500 a bit higher than a G3@333, but still 3,5 times
lower than a G4@450..., always accordingto dnet's client)


Any though about this ? Any way to debug ??

Thanks,

GoM

Ah, this problem.  I had it too with my nPower400.  I got rid of it by shutting down completely, and starting up again (into Linux).  I haven't had that problem since, at least with my kernel...

Hi!

I have some problems, Im using IBM PC server 330 with Adaptec Serverraid
card.. the problem is that the Redhat 7.3 does not recognize my second prosessor

Looks like the MP table only has 1 processor listed in it.
Perhaps NT 4 knows about this BIOS/MP table as a problem and has a
workaround for it.

Anyone know if Linux has anyone MP table quirks/workarounds to force
a second processor in a case like this?

Hi

I did something (dont ask) :) and now even the top command says CPU0 & CPU1..??
and both of the processor lights blinks when running a program..
Also the Server RAID card rocks better than before,
so perhaps the problem was "the newbie problem" ;)
