Yup. Are you saying it is simply not possible to access PCI config space of a device from a device driver unless the driver is in fact part of the driver stack associated with that device?
Yes.
Yeah, this is an already known issue from the beginning ;-). Technically, we don't have the PDO of the southbridge chip, therefore we cannot access it in anyway as documented by Micro$oft.
What is required to get into the southbridge driver stack?
From the little reading I've done the last day or two it seems that
a driver would not have to do very much once in the stack. Is it really not feasible? It would definately be the cleanest way.
