Can I use both processors with a non-SMP kernel? I don't need SMP, I would settle on manually assigning CPU affinity to each processor, but I gather FreeBSD can only handle 2+ CPUs with SMP enabled. On a 5.4 box without SMP mptables show both CPUs though: <...> MP Config Base Table Entries: -- Processors: APIC ID Version State Family Model Step Fla= gs 0 0x11 BSP, usable 6 11 1 =20 0x383fbff 1 0x11 AP, usable 6 11 1 =20 0x383fbff <...> dmesg.boot says only cpu0 is found, top doesn't see the other one, too.
