The dual VAX was the first machine we tried to make work, but for various
reasons including the machine's peculiarities and our own embryonic
knowledge, we abandoned it. The first working Plan 9 kernel was for a 4-CPU

there was a vax compiler and i think a vax kenfs implementation, i don’t know
if there was a vax cpu/auth kernel. quite possibly not.
currently i can only find my own post on tuhs confirming the vax was a dead
end. but i am sure jmk told me he found a vax compiler binary in the labs dump.

possibly true but multi-cpu boxes where becoming quite popular in the late
1980s and these have very similar kernel design challenges to multicore
Windows and Linux began on single-core single processor machines.
Multiprocessor had been around for some time--IBM's System 360 began using
multi-processors in 1968--but not for x86. Plan 9 first edition came out in
1992, at a time when multicore didn't exist, and multicore was released with

people wrote documentation for a reason; sometimes the documentation is

Btw, how do I reply to someone like you are doing? Copying and quoting manually

I finally read the article about asking questions, sorry if i was being rude or

And about the multi-core support, well I kinda moved away from it since I don't
really need it, I was just wondering if i can disable it in an easy way for the

In addition to the papers Ori pointed out, you may wish to read Francisco J
Ballesteros' Notes on the Plan9 3rd edition kernel:
https://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.75.5409
I don't know how obsolete this is for the current versions of plan9.
A big reason for doing Plan 9, as the linked article says right up top, was
supporting multi{core|processor} machines. And that took some research
because there really hadn't been that many around to write OSes for before
then. Some novel work resulted, work that still has relevance.

read: https://doc.cat-v.org/plan_9/4th_edition/papers/9
and once again, read:
Does plan9 have multi-core support? If it does, how does it manage it (what
files/man pages/docs do I read). If it doesn't have, how would I implement it.
