Does NetBSD-arm support SMP ?
I get to know the new Cortex-A8 is a dual core.
I believe that first we'd need an updated pmap, which the work Matt
is doing in the matt-armv6 branch would help with (as I think
Cortex is armv7?) the reason for this is the handling of virtual
vs physical addresses, all the older arms use virtually indexed and
tagged cache making SMP very hard to do.
Of course the sooner someone gets their hands on these things the
sooner it'd be ported to :)
Give a Cortex-A8 and I'll make it work. :)
