Working? :-)

Well, there are servers at reasonable prices and a lot of cores &/|
sockets with POWER 8 cpus. Mine has a lot of problems, though none
seem to be related to SMP :). I'm running 11-CURRENT and I get:

root@:/ # dmesg | grep CPU
FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs
cpulist0: <Open Firmware CPU Group> on ofwbus0
cpu0: <Open Firmware CPU> on cpulist0
cpu1: <Open Firmware CPU> on cpulist0
SMP: AP CPU #8 launched

root@:/ # sysctl kern.sched.topology_spec
kern.sched.topology_spec: <groups>
 <group level="1" cache-level="0">
  <cpu count="2" mask="101,0,0,0">0, 8</cpu>
 </group>
</groups>

Cheers,

Luciano.
