All
I go through the code and curious about the value of pci_bus.primary
of Bus#0, the root bus.
On x86, the root bus is get by,
root->bus = pci_acpi_scan_root(root);
While I scan the code not find some place set the *primary* field.
I think this value indicate the upstream bus number, while for root
bus, this value should be?
So this value of the root bus is any value? Or some restriction?
