The explanations by Tom and Marc made a few things clear for me:
- The physical HT structure is not what we want to model.
- The appearance of HT and topology in PCI config space is what matters.
- 18.0 is not a PCI bridge, don't pretend it is one
With that in mind, I'd like to propose another dts. I know that it has its own quirks, but it can serve as a discussion point.
I'm beginning to feel like we're thinking too much.
The fact is that whether or not the three HT links are a bridge, there is routing in there that makes each link logically the parent of a different set of devices. do we call that a bridge?
I don't know what to do with bus@1.
ah well it's been a long day, will look at this later. For now let's get myles patch in and try to see where that goes. I think I'm not ready for this dts. But if myles wants to try it that's fine too.
