SMP supported (in upcoming 2.2)?

Post by John Reynol » Mon, 29 Jul 1996 04:00:00



Hello,

I searched the mail/news archives looking for news about SMP support.
Most of what I saw as responses to the "SMP question" was ``it's being
worked on'' or ``yeah, it'll get here sometime'' ...

Most of these messages were "old" (6 months, sometimes years old) so
what I would like to know is if FreeBSD 2.2 (when it is released)
going to support SMP "out of the box"?  If not, are there plans to do
such a thing beyond FreeBSD 2.2? I find myself drooling over dual
Pentium Pro boxes (drool only, no cash :) and am just wondering if this
wonderful OS is going to support both chips at once.

In a nutshell, what are the "official plans" for bringing SMP into FreeBSD
for the masses?

Thanks,

-Jr

Probably when it works better.

1. SMP support and current->mm behaviour on 2.2

I'm working on a driver that uses current->mm in a function that
ferrets out a physical address for a user-mode buffer. The function
seems to work fine on a 2.2 kernel without SMP support compiled in, but
it crashes the driver with SMP support there. I investigated and found
that current->mm was returning NULL. Is there something I'm missing?
This is my first time working with Linux's SMP support.
