 What is so special about A8? We have some ARM code in tree, is Cortex
SO different from previous architectures? As far as I understand, main
problem in such platforms is different perefireal devices on each next
chop and board, which doesn't have "common denominator" like PCI bus
or other standard pieces, which helps a lot on PC (x86, amd64) architecture.

 BTW, we have infrastructure for crypto accelerators ;-)

 And what about NUMA... I know only one (almost-general-purpose) OS,
which has full support for NUMA. It is Sun^WOracle Solaris. Ant it
does it very well (not to forget about boxes like SunFire 25K with 72
2-core sockets at, as fa as I remember, 18 processor-memory boards).

    I participated in project, which added NUMA support to Sun JVM
HotSpot, and Solaris was only one which gives us all needed
information -- nor Linux nor  Windows either had not needed API two
years ago, and as far as I know, there is no big changes in this area
for them (but I could be wrong).

 So, I cannot say, that FreeBSD is seriously behind the pack in NUMA suppor=
t.
