It works, ie. with this patch applied the PCI resources on the nx6325 look exactly like with commit a76117dfd687ec4be0a9a05214f3009cc5f73a42 reverted.

This leaves the issue of the serial ports on ia64 open. So it may be that we'll have to instead revert the use of pci_claim_resource() on x86, but it sounded like we'd have people looking at that. I'd rather make forward progress on something that looks this trivial than revert it just to get us back to the pre-regression thing.

It works fine for me on the original hardware where the problem was reported. I don't see any change between iomem/ioport layout between the kernel without this patch and the kernel with this patch. I don't have the problem card I had in the same slot, so I would like to move it and run another test.

I suspect you have always had the error, it's just that back before the commit that started using "pci_claim_resource()", we did that "find_parent_resource()+request_resource()" by hand. So before commit a76117dfd687ec4be0a9a05214f3009cc5f73a42, the ROM resources were done with: pr = pci_find_parent_resource(dev, r); if (!pr || request_resource(pr, r) < 0) { r->end -= r->start; r->start = 0; } inside pcibios_assign_resources(), and it would never warn about it, it would just silently mark the resource unregistered (and then we'd re-allocate it later). So I _think_ that you actually are getting the same layout as with 2.6.30, but with a warning that didn't exist in 2.6.30. Can you verify? With the change to use "pci_claim_resource()", it initially changed things to use "insert_resource()", and that shouldn't have even succeeded, but apparently did! That's a bit scary. The patch to make it use pci_request_resource() should have made it have the same behavior as we had in 2.6.30 - albeit with the warning (that we didn't use to have). I do wonder why the insert_resource() seems to have worked, though, so maybe I'm misdiagnosing this. Can you post your /proc/iomem from 2.6.30?

Can you verify? You're absolutely correct: /proc/iomem on 2.6.30 and 31-rc5+ are identical, the only difference being 2.6.30 not complaining about any collisions. > With the change to use "pci_claim_resource()", it initially changed things > to use "insert_resource()", and that shouldn't have even succeeded, but > apparently did!

So this is not a regression per se. The warning looks a bit annoying, but in fact I believe that the warning is correct, and is showing us a real problem. Well, not "problem" exactly, but an issue. I think that what is happening is that pci_find_parent_resource() may be in fact finding another parent resource than the one we strictly want (the pre-existing one). And I think it's brought on by the fact that this is a ROM resource. I bet that what is happening is: - the PCI bridge has a _prefetchable_ bus resource window at ff600000-ff6fffff : PCI Bus 0000:02 - the PCI bridge is a transparent bridge - the BIOS has set up the ROM (BAR 6) at ff680000-ff69ffff : 0000:02:03.0 - We have for some reason marked the ROM as being non-prefetchable. and what happens is: - pci_find_parent_resource() refuses to use the ff600000-ff6fffff PCI bridge resource, because it is marked IORESOURCE_PREFETCH, and the ROM resource is not so marked. - But because it's a transparent bridge, once we've iterated over the bridge window resources, we have a couple of resources that point back to the parent of the bridge - the PCI root resources. So now pci_find_parent_resource() will return that instead - request_resource() will (correctly) notice that the root resource already has other resources at that address (the PCI brige window!) and will refuse to insert it - leading us to re-allocating the BIOS-provided resource later (to the non-prefetchable bus window) - but when we for a short while (incorrectly) used 'insert_resource()' in pci_claim_resource(), it would recurse back into the prefetchable window, and everything would work - because a ROM resource is actually perfectly happy to be in a prefetchable window. So I think I understand the behavior on your box, and the warning was actually correct and useful - our PCI layer is being stupid. We should mark ROM resources as being prefetchable. Hmm.. We do seem to _try_ do exactly that in pci_read_bases(). I wonder what I'm missing, and where that bit is then cleared. Or whether we're doing that ROM BAR probe somewhere else too..

Manuel, could you compile your kernel with CONFIG_PCI_DEBUG enabled, and then boot it with "pci=earlydump", and send me the dmesg of a kernel boot? You may need to make sure that CONFIG_LOG_BUF_SHIFT is big enough to get it all, and perhaps use "dmesg -s 1000000" (some versions of dmesg will truncate the result to 64kB or something by default, and depending on just how verbose your boot ends up being, you migth lose things).
