Per chip but we usually only wire one up per machine. > In general it is quite nice when "-nodefaults" does not create > neither PHB nor LPC so the user can add them manually with parameters > different than defaults. In this case though, PHB and LPC bridges are all part of the P8 chip, and I'm trying to represent that topology as best as possible. I think "-nodefaults" for Pnv should only be about the devices we attach to the LPC/PHB not the busses themselves. Cheers, Ben.
