All the way to the end :-)
Seriously: I haven't done any timings yet. I'm mostly just upping
the load to see how stable it is. A -j4 completes and a -j8 is in
progress. If that completes I'll be doing UP vs. SMP comparisons.
There's a visible speedup, so things look good. I hope to have
hard data next week or so.
Random notes:
o It should be safe to enable interrupt delivery to all CPUs
and play around with programming the TPR of the CPUs.
o SMP works with 4BSD only, but raj@ just told me he has ULE
support for SMP.
o We should take advantage of the OpenPIC timers to driver
hardclock, etc.
o Cache prefetching hasn't been enabled on the AP yet.
