[9fans] multiprocessor

[Andrew]

I have an older system that claims to be able to run two processors. Its
an ast premmia gx p/90 (stunning i know). Ive got two p90's in it and
the jumpers set properly, the kernel i built for it has the arch mp
apic line in the misc section also. But alas I cannot get it to find
both processors. Is this because of intel's pathetic attempts at smp
early on? or is there something else i may be missing?

thanks

[9fans] Ultrasparc II

[Peter Downs]

I've located the Ultrasparc II User's Guide, which has a nice
28 page section on MMU internals.  Some of the mechanisms are pretty
similar to sparcv8.

Has anyone out there worked on a sparcv9 compiler?

Does the system or documentation say anywhere it is MPS 1.1 or 1.4 compatible?
Some early manufacturers rolled their own MP hardware.

We still have dual-P90 systems running.

of course.

at the risk of pointing out the obvious, can we
assume you've removed the nomp line from plan9.ini
(and that you're using the correct plan9.ini)?
