All,
I want to confirm something for the pci_dev->resource[].
As in the definition in the pci.h, this resource array is divided into
several parts.
0-5 for standard PCI resources
6 for ROM resource
7-10 for bridge resource( if no iov )
1. For P2P bridge, 0-5 is left empty?
2. If so, in code pci_setup_device(), I think it set the wrong resource.
It call pci_read_bases(dev, 2, PCI_ROM_ADDRESS1), for a p2p bridge.
And in pci_read_bases(), BAR information is retrieved and set to
pci_dev->resource[0|1].
3. If pci_setup_device() just set first two resource, the child bus will
point to empty resource.
In pci_alloc_child_bus(), child->resource[0-3] will be point to
bridge->resource[7-10], which is not set in pci_setup_device().
4. Another question is, is there any convention for pci_bus->resource[].
[0] for io, [1] for mem, [2] for prefetch?
