Ooh, interesting. I thought that patch was a functionally equivalent 
cleanup of

	pr = pci_find_parent_resource(dev, r);
	if (!pr || request_resource(pr, r) < 0) {

to

	if (pci_claim_resource(dev, idx) < 0) {

but yeah, it's not exactly the same. pci_claim_resource() uses 
'insert_resource()' rather than 'request_resource()'.

We could certainly revert the commit, but I also wonder whether we should 
just change 'pci_claim_resource()' to use request_resource() instead.

I _think_ the use of "insert_resource()" is purely historical, and is 
because that broken function _used_ to not look up the parent, but instead 
do that crazy "pcibios_select_root()" thing, and then it really does need 
to recurse down and "insert" the resource in the right place.

We should no longer _need_ to do the "insert_resource()" thing, since we 
are inserting it into the exact parent that we want (as of commit 
cebd78a8c: "Fix pci_claim_resource").

And if that "insert_resource()" in pci_claim_resource() ever does anything 
fancier than the raw "request_resource()", then that's a problem anyway.

Willy, comments? x86 historically has never used pci_claim_resource() at 
all (it always open-coded the above) except for some quirk handling. So 
I'm pretty sure that a patch like the below should be safe and correct. 
But it's parisc machines that always seem to break.

Added Andrew Patterson to the Cc, because his report was what caused us to 
originally look at pci_claim_resource() and make it use 
"pci_find_parent_resource()". We just never went whole hog, and we left 
that broken "insert_resource()" around.

So Rafael and AndrewP, does this work for you? (I also moved the "dtype" 
thing around, it bothered me).

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

Thanks,

Ok, I'll commit it.

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.

This patch introduces a warning on my system:

pci 0000:02:03.0: BAR 6: address space collision on of device [0xff680000-0xff69ffff]

Below are iomem and pci dev info in the bad and good cases (good = patch reverted).
This isn't fatal here:  the e1000's disabled expansion rom gets reassigned to elsewhere.

This change also works with the original "problem" card. I don't see any
issue with the serial port, but I have only tested on an rx6600.

Heh, that's funny. 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?

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.

Ok.

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).
