i've had a core i7 machine for some time with 4c/8t.
unfortunately, the mp table has only 4 processor entries.
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.

Extremely doable.
If you forget about bus information.

Nemo, I wonder if you have any way to allow others to collaborate on
that code? Seems like there's certainly interest, and the ACPI spec
*is* open...
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 info

The bad news is that is does not work yet.
What remains to be done is to supply bus information to the kernel
correctly, and that's not happening as of today.
where can I find the
fix, and there's the joy of acpi aware drivers.
what does this mean?

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...

evidently this is also the case on core i5/xeon 3 machines
with = 4t as well.
in my case, i was given a lucky break by bios which gave
the processors apic ids 0, 2, 4, 6 and the
18 matches
