Some more interesting findings in this field lead me to another related
question:
what is the relation between kern.smp.cpus, kern.smp.active and
kern.smp.maxcpus?
To my understanding, it should be:
If the machine has more than one CPU, and SMP and apic are enabled in
the config file, then
kern.smp.cpus =3D nof cpus in the system
kern.smp.active =3D 1
kern.smp.maxcpus =3D 16
else
kern.smp.cpus =3D 1
kern.smp.active =3D 0
kern.smp.maxcpus =3D 1
This is the expected result, and also the result I get from my single
CPU Pentium 3, running 6.3-RELEASE:
kern.smp.cpus: 1
kern.smp.active: 0
kern.smp.maxcpus: 1
=46rom my single CPU sparc64, running 7.0-PRERELEASE, I get:
kern.smp.cpus: 1
kern.smp.active: 0
kern.smp.maxcpus: 16 <-- why not 1??
=46rom my Core2Due, running 8.0-CURRENT, I get:
kern.smp.cpus: 2
kern.smp.active: 1
kern.smp.maxcpus: 16
which is OK, but nevertheless SMP is not defined in sys/param.h (see
previous posts).
Thanks for any insight,
