is anybody actively working on this (SMP)?
I've made my mind up and will buy the new board from ASUS P55T2P4D which
features two Pentium processors as soon as I can get hold of one here in
Problem is, I don't know anything about Intel-assembler and what is needed
to control and synchronize the actions between the processors but this shouldn't be
too hard to find out (with a little help from you out there maybe:-).
I figure quite a lot of code out there is dependent on the fact that only
one process can be executing inside the kernel at one time (like the
VXLOCK example). I don't think that I could work out all of this on my own,
(well I think I can, but I'm sure it will take ages :-) so is there
anybody out there willing to participate in SMP development? I'd really like
to get this into the kernel for the release after the next one, probably
together with a revamped buffer and file cache system, which would make
NetBSD a superior operating system :-)
Any takers to join my effort?
