Hi ! I have a problem on platforms with multiple PCI domains and allocating resources. The mechanism of having the arch set PCIBIOS_MIN_IO and PCIBIOS_MIN_MEM to avoid allocating things over the legacy areas among other things doesn't work well for us. The reason is that on platforms where resource addresses are remapped because the PCI bus isn't mapped 1:1, the values of the ranges we try to avoid (typically 0...4K for IO space and legacy VGA memory) is different from one domain to the next. Right now, I'm doing a workaround for .28 that will reserve those regions on some platforms before the allocation occurs, but it's a bit fishy, especially it gives strange results when using things like legacy IDE PCI cards that really want to allocate in those areas. Ideally, we would need to pass the pci_bus pointer to those macros. Thus, is there any objection to me replacing those accross the board with something like that ? resource_size_t pcibios_min_assign_io(struct pci_bus *bus) resource_size_t pcibios_min_assign_mem(struct pci_bus *bus) Please holler if you have objections before I start fixing everybody :-) Cheers, Ben. -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
