Re: static config for CPUs with K8 example

Ron,

If the 8111 is connected to 8131. Should add the config for 8131 and say its
north is "amd8111".

Regards

Yinghai Lu

主题: static config for CPUs with K8 example

OK, I am hoping this is the kind of thing that will work for the K8.

First, in cpu/k8, define a file, chip.h:

struct cpu_k8_config {
        struct chip *north, *south, *east, *west;
};

Thenin cpu/k8/Config.lb, add this line:
config chip.h

Note this file could be called anything, but chip.h is a habit for me.

In the mainboard config (mainboard/arima/hdama/Config.lb), you set things 
up as follows:

southbridge amd/amd8111 "amd8111"
end
southbridge amd/amd8131 "amd8131"
end

# pull in all includes, etc. for  the k8. 
# should we have a 'noise keyword' for this, e.g. 'cputype k8'?

dir /cpu/k8

# define the CPUs, their names, and their connections.
cpu k8 "cpu0"
  register "north" = "amd8111"
  register "east"  = "cpu1"
end

cpu k8 "cpu1"
  register "north" = "amd8131"
  register "west"  = "cpu0"
end

This will result in initialized structures, per-cpu, that "do the right 
thing".

I've hit a bug I have to ask Greg about, but this is a rough idea. 
Comments?

ah, ok, I need that more complex diagram that stefan sent me. All the 
diagrams he has sent so far show no link from 8131 to 8111 ...

Stefan? can you send 2 and 4 cpu pictures again?

are the names 'north, south, east, west' acceptable to everyone? It 
follows current nomenclature.
