the test development branch is called sommerfeld_i386mp. the i386 in
the name is quite significant. there is no SMP development branch for
sparc. all the -current (and probably netbsd-1-6) does is to spin up
well... that's all it does by default. but there's this #if 0 in
locore.s you can enable and it will attempt to run the other cpus
and blow up. it *should* work but i haven't figured out why it blows
up yet (and haven't tried for a long time either, :-( )
the second cpu. that's all. you may want to check the following url to
compare various ports' status on SMP, etc. :
