Information about Linux/PPC SMP mode
This document and the related code was written by me
(Cort Dougan, firstname.lastname@example.org) please email me if you have questions,
comments or corrections.

If you want to help by writing code or testing different hardware please
1. State of Supported Hardware
PowerSurge Architecture - tested on UMAX s900, Apple 9600
The second processor on this machine boots up just fine and
enters its idle loop. Hopefully a completely working SMP kernel
on this machine will be done shortly.
The code makes the assumption of only two processors. The changes
necessary to work with any number would not be overly difficult but
I don't have any machines with >2 processors so it's not high on my
list of priorities. If anyone else would like do to the work email
me and I can point out the places that need changed. If you have >2
processors and don't want to add support yourself let me know and I
can take a look into it.
BeBox support hasn't been added to the 2.1.X kernels from 2.0.X
but work is being done and SMP support for BeBox is in the works.
CHRP SMP works and is fairly solid. It's been tested on the IBM F50
with 4 processors for quite some time now.
