My copy of pci_read_bridge_bases() in jbarnes's linux-next tree
doesn't do anything like that.
284 void __devinit pci_read_bridge_bases(struct pci_bus *child)
285 {
...
369 if (base <= limit) {
370 res->flags = (mem_base_lo & PCI_PREF_RANGE_TYPE_MASK) |
371 IORESOURCE_MEM | IORESOURCE_PREFETCH;
372 if (res->flags & PCI_PREF_RANGE_TYPE_64)
373 res->flags |= IORESOURCE_MEM_64;
374 res->start = base;
375 res->end = limit + 0xfffff;
376 dev_printk(KERN_DEBUG, &dev->dev, " bridge window %pR\n", res);
377 }
What's going on?
