Hi willy, Linus,
I've been chasing a bug for the past week or so that I can't seem
to figure out, and was hoping to get your eyes on it.
The basic summary is, we can't allocate a memory resource for our
BAR after a PCI hotplug operation. We've been able to bisect it
down to d33b6fba2c4350651f3f61ff2ab858a2f116e9a4 (Resources:
insert identical resources above existing resources).
This happened around the 2.6.19 timeframe, and we just haven't
noticed it until now. My testing has been with latest 2.6.28-rc8
release.
Since it's been around for so long, I don't think this is urgent
enough to hold 2.6.28, but it would be nice to understand and
fix. :)
I've got a lot of data that I'll include in this mail, but the
general "table of contents" are:
(a) console log from mainline
(b) console log with revert patch applied
(c) memory map presented by firmware
(d) dmesg from mainline
(e) dmesg with revert patch
(f) lspci -vv output
(g) the revert patch I used
The only real difference between (a) and (b) is this error:
pci 0000:c3:00.0: BAR 0: can't allocate mem resource [0xfe000000-0xfdffffff]
There was no significant difference between (d) and (e), but I
included them both for completeness.
As regards (g), I couldn't do a plain 'git revert' because of
conflicts due to changes since 2.6.19. I manually reverted it,
and I'm pretty sure I got it right, but that might be worth
double-checking too.
Thanks.

I'm missing some pieces I'd like to see: /proc/iomem before and after, and
lspci output before and after (you do give lspci output, but only one, and
I can't tell if it's before or after).
Also, is it just the error message, or does it actually affect
functionality?

Oh - one more thing. Your revert is very complex, and a simpler revert
(that _should_ revert just the actual behavioral change) is just the
two-liner that removes these two lines:
if ((first->start == new->start) && (first->end == new->end))
break;
in __insert_resource.
So can you check if your more complex revert really has the same behaviour
as just removing those two lines?
Matthew: I do suspect that the "insert below" patch is wrong. Look at
"pci_claim_resource()", for example: it uses insert_resource() to insert
the PCI device resource into the resource tree. But if the PCI device
resource has the same size as the bus window, that commit changes it to
insert it as the _parent_ of the bus window, no?
Of course, on a PC, the only user of pci_claim_resource() would be some
PCI quirks that should never trigger this, but it's an example of the kind
of behavioural change that that commit introduced, and which looks
like it could result in a wrong resource tree.
I'm not finding the original discussion that resulted in that patch,
though, so I have a somewhat hard time to judge the reasoning. It's from
almost three years ago, I don't remember details even if I had been
involved with it (and judging by the sign-off path, I hadn't).
Matthew, do you remember the context of that commmit d33b6fba2?

Yeah, I knew I forgot to send the contents of /proc/iomem. I'll
include them below.
I'll also include the lspci output for after. The one I included
in the last mail was for 'before'.

Hm, that is a good question. ;) The particular device I was
testing with was an infiniband device, and I have never actually
pushed any traffic over it; just used it to reproduce the error.
I can try and hook the card up to something and push traffic over
it, but that will have to wait until Monday. Maybe Justin (cc'ed)
knows, since he was the one who first reported this to me.
Lots of data follows. The revert output I'm including is with my
complex revert patch. I'll try the 2-liner next and respond in a
separate mail.
(a) mainline /proc/iomem before hotplug
(b) mainline /proc/iomem after successful hot-remove
(c) mainline /proc/iomem after hot-add + BAR error printk
(d) mainline lspci -vv after operation (c)
(e) revert /proc/iomem before hotplug
(f) revert /proc/iomem after successful hot-remove
(g) revert /proc/iomem after successful hot-add
Thanks.

Ok, this definitely shows that the commit in question generates a bogus
resource tree:

This is _not_ the correct nesting. PCI bus 50 is inside 4f, which is
inside 4e. Yet the resource tree has these reversed, and shows 4e inside
4f inside 50 (and 51 inside 52). And yes, the reversal happens exactly
when the size of the inner resource has the same size as the size of the
outer one - and then the inner one has been inserted "too high" in the
resource tree.
So this is very clearly the direct (and intended, but incorrect) result of
that commit d33b6fba2c4350651f3f61ff2ab858a2f116e9a4. Reverting it (using
my two-liner rather than your version, though) is almost certainly the
right thing.
We have the exact same issue here:

> 806a0000000-806bfffffff : PCI Bus 0000:54
Again, the nesting is wrong, adn for the exact same reason, even if the
pattern is slightly different (ie noe bus #4e is in the right spot in the
hierarchy, because it has a different size).
Here's the relevant parts of the lspci that show the bus hierarchy
(very aggressively snipped from your huge lspci output):

ie the bus number allocation really is that bus #53 is inside #52, which
is inside #51, which is inside #50, inside #4f, inside #4e..
Your machine is an insane mess of PCI bridges, which is probably why you
see this, while most other people probably never will. But I bet it
happens on other machines, and I also bet it generally doesn't really
result in any problems.
Because in practice, the fact that the resource tree has been nested the
wrong way around probably almost never actually matters: especially as it
happens only when the nesting resources are the same size, which also
means that there can be no _other_ resources that would fit inside the
true outer one.
So even if lots of other people see some of the same issues, it doesn't
cause any other symptoms, and that in turn explains why we've had this
going on for such a long time (since 2.6.16 or whatever).

And yes, now the resources nest the right way, and match the actual
physical topology of the bus.
So yes, that commit really is causing problems. At the same time, I would
worry about even the trivial two-liner removal before the release of
2.6.28, because while we clearly need to do it, equally clearly this
doesn't seem to be a _huge_ problem, and I worry that the brokenness of
insert_resource() might have other subtler results.
So my inclination would be to prepare the appended patch for the 2.6.29
merge window, but not commit it yet. At least as long as you can't
actually show any real devices misbehaving (ie the resource tree is
clearly not right, but since I suspect that everything _works_ despite
that, this is not a high-priority issue and the unlikely but potential
pain is thus much bigger than the negligible gain of fixing it at this
point in the 2.6.28 release cycle).
Oh, and it would still be good to know why Matthew wanted it this way to
begin with.
Jesse? Matthew?

It affects functionality. The BAR is not reprogrammed after hotplug. Below is an example:

I'm not sure what motivated this change, it was pushed back in June of '06.
/me digs through mailing list archives Hm can't seem to find anything useful.
Hopefully Matthew's memory will be more helpful.
I can put your patch in my -next branch if you think it would help (not that -
next gets a ton of testing, but hey)...

Better than nothing, I guess.
We may end up back-porting it (since Chen confirms that it's not just a
warning, it actually affects functionality), but let's get it some testing
in -next first and then eventually in the merge window. So you might mark
it for attention for 'stable@kernel.org' as you commit it.

I pushed it to my -next branch, though I forgot to add the stable@ cc and fix up the comments while I was there... I think I'll have to rebase anyway, so I'll take care of both of those when I do.

commit d4e9908a08199fe4d728c68cc7c5ca2d827ae99fAuthor: Linus Torvalds <torvalds@linux-foundation.org>Date: Sat Dec 13 17:37:57 2008 -0800
resource: revert parent nesting of identical ranges Revert the change that causes inverted resource nesting in the case of identical resource ranges. Initially introduced by d33b6fba2c4350651f3f61ff2ab858a2f116e9a4, this change was provided without a justification and seems to cause problems on some machines in the face of PCI hot plugging. The patch makes resources registered against an existing but identical range nest as children of the existing resource, rather than parents.

You're quite correct. This was actually the intended behaviour of
insert_resource() ... the problem is that pci_claim_resource() is using
it wrong.

Basically it was that we came across a machine with the opposite problem
-- that we found a parent after we found a child (and claimed the
child's resources), and had no way to insert the parent's region above
the child's region. Alex's machine finds the child after the parent and
needs to insert the child's resource inside the parent's resource.
pci_claim_resource() should be looking through the resources that belong
to the parent bus, trying to insert inside each of them, not just
taking the root resource and wandering all the way down. I'll work on a
patch tomorrow to do that unless someone beats me to it.
