What additional steps are needed when building the model to get an SMP
system?

Ideally this would eventually be documented in
http://wiki.xen.org/wiki/Xen_ARMv7_with_Virtualization_Extensions/FastModels 
but it is probably a bit premature for that right now.

I think it is sufficient to do the following after opening the project
("sgcanvas <SGPROJ>") and before clicking the "Build" button.

      * Right click the header of the "cluster" in the diagram (the top
        bit of the box which says "cluster" in it)
      * Select "Object Properties" from the context menu
      * In the "Parameters" tab update the "num_cores" variable, e.g. to
        "0x4"
      * Click build and continue as usual.

Do that sound about right? It appears to work for me at least. I've not
applied all your patches so I can't see how many processors there really
are.

Ian.
