Re: Fw: SMP Support

[Cort Dougan <cort@fsmlabs.com>]

There are some tricks for the 750 on SMP that no-one has actually tried
yet.  I did some early work with it that ended up with horrible
performance.  The 750's don't broadcast TLB invalidates and that really
messes SMP up for us.

I'm not sure of the 755 follows in this tradition but I'd suggest checking
carefully for that.  SMP works well on anything other than 750's, though.
