Hi everyone,
I've just committed a partial implementation of the SUNW,retain word and so have moved further into booting OpenSolaris. Currently it's only a partial implementation because I can't get Qemu to perform a warm restart without crashing the guest, so I may need to revisit this later. Fortunately, the SUNW,retain word itself is there which now enables the OpenSolaris kernel to get further during boot:

Looking through the OpenSolaris source code[1], it appears that fill_cpu() is expecting a portid property on the CPU nodes. Also searching further within the same file, it seems have_pci() is expecting a portid property on the PCI bus node too.
Does anyone with experience with real Sun kit know what the portid property for both the CPU and PCI device should be set to? It's fairly obvious that it's an integer, but I'm not sure how it should reflect the virtual hardware.
ATB,
Mark.
