I haven't gotten SMP to work on my G4/500DP yet, but I agree that this
should work:
$ cat /proc/cpuinfo
I'm not positive that shows that the second CPU is actually being used
(I have seen in x86 Linux/BSD where the second processor is shown in
/proc/cpuinfo yet apparently not actually running any threads on the
second processor). If you load the machine with some workload and run
"top" it may show CPU use above 100%. That is a good indicator that the
second processor is in use. However, if it shows less than 100% that
does not *necessarily* mean that it is in use. It is my understanding
that newer versions of top can recognize that there is actually "200%"
of CPU available and is smart enough to look at each CPU load
individually and correct it to a 100% scale. Since I don't have mine
working at all yet, I can't say any of this is a correct answer.
If I'm way off base here, anyone with better knowledge should feel free
to enlighten me with a clue by four =)

Hello Kjell,
Try:
$ cat /proc/cpuinfo
It should provide details on each of the CPU's that it finds.

Subject: SMP on 9500MP
Hi,
I built 2.4.13 with SMP support for use on a 9500MP (2 x 604@200).
When I
boot I see that it switches into SMP mode but I don't think it's actually
using both processors, and top still only has one processor line. Is
there a way to tell how many processors the kernel is recognizing? Also,
is anyone else running an SMP kernel on this type of machine?
Kjell
