My impression is that mp tables are getting worse and worse on new
hardware because vendors assume everyone is running an acpi-aware OS.
Does anybody have an (informed) opinion as to
There's an initial implementation of acpi, but it's not yet ready.
Getting boot-time MP info is not enough, the information regarding
bus/interrupt entries is provided in many cases by AML methods.
So, in short, you need all of acpi to get that information.
The good news is that it's implemented.

good point. two reasons

Does that imply that we can expect the acpi tables to be often

If you forget about bus information.

Well, the code is done. The interpreter seems to be working, and the
tables seem to be parsed.
The problem is that we have to supply bus in

An example, enumerating and configuring PCI using acpi methods,
enumerate and configure X using acpi methods.

i hope i'm not being ignorant here, but i just went through
the linux code for enumerating pci. they try every trick in
the book,
I may be mistaken, but I think they have all sorts of ways to
enumerate devices, both with and without acpi.

Not that this is a great answer, but the way I've done SMP boot without
parsing either the ACPI or MPS tables was to issue broadcast init and
startup IPIs, rather than targeted ones. All the CPUs in an i7-based machine
came up, fwiw...

Hello 9fans,
My name is Scott Sullivan and I'd like to introduce myself and seek out
other 9fans in the Greater Toronto Area.
I first learned of Plan 9 back in 2007 and took a cursory glance over
the system and a couple of the introductory papers and was fascinated.
Since then I've spent co
Read the source for the programs and the system, and experiment with
them at will. It´s fun.

Nemo is too modest, what he really meant was that you should take a
look at this:
http://plan9.lsub.org/who/nemo/9.intro.pdf
and then experiment at will :)
you will hardly find a better resource for delving into Plan 9.
