Also, what if we had the possibility to run code for disabled devices - then the vpci hiding could cleanly happen when the device is disabled instead of checks from northbridge code. Like a .disable functor in device_ops?
We do. If you run it in phase2 it runs independent of the enabled flag, and could use that to do any disabling that was needed. It's a little confusing to put the device in the tree then, though, because it will never show up in lspci.
I guess I mean a way to run disabling code if a device doesn't appear in the mainboard dts at all. E.g, there is a northbridge/amd/geodelx/graphics.dts and if the mainboard dts doesn't source it or it's disabled, a disabling function would be ran. This is just something that optionally wired built-in PCI devices might be interested in, not the typical case of PCI slots.
I can imagine it would get tricky to implement and quite likely it's just a bad idea.
