Feedback Needed - CPU Count

[jimp]

Trying to figure out the best way to see/retrieve not only the count of CPUs, but how they are arranged in a system.

From what I can see/test here, I think I have a good idea, but what I really need is to see the output from a whole bunch of different setups. Especially those with multiple physical CPUs

So if everyone could run these commands from Diagnostics > Command or the shell and copy the results here, it would help a ton, thanks!

sysctl kern.smp.cpus; grep "SMP.*package.*core" /var/log/dmesg.boot

Sample output:

kern.smp.cpus: 2
FreeBSD/SMP: 1 package(s) x 1 core(s) x 2 HTT threads

If you have a CPU count greater than 1, but the second line doesn't show, please run:

grep "SMP" /var/log/dmesg.boot

Results so far (collected from pfSense and FreeBSD servers):

kern.smp.cpus: 1 / (empty)
kern.smp.cpus: 2 / FreeBSD/SMP: 1 package(s) x 1 core(s) x 2 HTT threads
kern.smp.cpus: 2 / FreeBSD/SMP: 1 package(s) x 2 core(s)
kern.smp.cpus: 2 / FreeBSD/SMP: 2 package(s) x 1 core(s)
kern.smp.cpus: 4 / FreeBSD/SMP: 1 package(s) x 2 core(s) x 2 HTT threads
kern.smp.cpus: 4 / FreeBSD/SMP: 1 package(s) x 2 core(s) x 2 SMT threads
kern.smp.cpus: 4 / FreeBSD/SMP: 1 package(s) x 4 core(s)
kern.smp.cpus: 4 / FreeBSD/SMP: 2 package(s) x 1 core(s) x 2 HTT threads
kern.smp.cpus: 8 / FreeBSD/SMP: 2 package(s) x 4 core(s)
kern.smp.cpus: 16 / FreeBSD/SMP: 2 package(s) x 4 core(s) x 2 SMT threads

If your results are identical to ones already on the list, no need to post them. Thanks!

Runs without any issue.

I added a summary to the initial post with results so far, if your results are identical to ones already listed, no need to report them.

Thanks!
