Eric,

Thanks for the advice.
I will try to add the SMP support in the northbridge/amd/amdk8 at first.

Regards

Or at least work with the others working on it and it can be a cooperative
venture.

Basically it is the nature of open source if something isn't implemented
you can wait or you can write it.

So far what I have seen is a talented user figuring out LinuxBIOS.
I have not seen a developer giving constructive giving constructive
feedback or helping in the development.

My general advise to people who want to just use the Opteron port
is stay away.

For developers the advice is dig in, just be aware everything is
undergoing active development, and there are a lot of pieces
that have been stubbed in but have not been written correctly yet.
SMP support is one of those.

Eric

OK.

There are few levels of this.

Coherent Hypertransport setup.

Mapping resources to their location in the coherent HT domain.

Memory Initialization on secondary cpus.

Starting up the secondary cpus.

Stefan Reinauer is currently working on Coherent Hypertransport initialization.
And there is a hardcoded version of it in northbridge/amd/amdk8/coherent_ht.c

Ron is currently working on getting the new Config language going and probably
in the week or two we will switch over to that.

While not writing memory initialization code I am busily getting the kinks
out of romcc.  I think I have just squashed the last of the bugs in register
allocator.  I thought I was there earlier but a few extra ones cropped up
after I rewrote the algorithms so they ran in a reasonable amount of time.

And since the reasons for my original hesitation are no longer valid I have
implemented goto support in romcc.  I think I am only short enumeration constants,
macros with arguments, and switch statements to have a full implementation of
C.  Admittedly there are some things I cannot support like non const
static variables.  And I still have to fix the limits on variables,
currently I don't limit chars and shorts when stored in larger
integers to just the low bits of the register.
