It's a duplicate of 16334. Or rather 16334 is a duplicate of this
but the discussion about the issue was more developped in 16334.
Anyway this is not a regression (at least not recent) and the fix
from Al is in the vfs tree in the for-next branch on commit
6c2bdaf089a3876226893fab00dd83596c465ad2
"Fix reiserfs_file_release()"

Since it's a reproducible deadlock maybe the fix should go upstream faster
than v2.6.36?

May be yeah. Although the fix is not a naive trick and it changes a sensitive
piece of code.
Don't know what Al has planned with it.

As far as I know, it's only a lockdep warning, not an actual deadlock.
And it's in a class of lockdep warnings that we've had for a long
time, and has never actually triggered as a read deadlock afaik.
I also don't think it's a new warning - or at least I don't see why it
would have started triggering after 2.6.34.
My preferred fix in many ways would be to make the locking in the VM
layer less incestuous. For example, we could fairly easily move the
final
if (vma->vm_file)
fput(vma->vm_file);
outside the actual mmap_sem lock (well, "fairly easily" here means
keeping the list of free'd vmas around for longer, probably in the
task_struct thing, and then replacing all the
"up_write(&mm->mmap_sem)" things with a "unlock_mm(mm)" looking
something like
static void unlock_mm(struct mm_struct *mm)
{
struct vm_area_struct *vma_list = current->vma_to_free;
if (vma_list)
current->vma_to_free = NULL;
up_write(&mm->mmap_sem);
while (vma_list) {
struct vm_area_struct *vma = vma_list;
vma_list = vma_list->next;
fput(vma_list->vm_file);
kmem_cache_free(vm_area_cachep, vma);
}
}
which would fairly trivially delay the actual 'fput()' to after we
hold no locks.
I dunno if it's really worth it, but it doesn't look all that
complicated, and it would avoid at least _some_ lock dependencies.

Two commits in the X server repo (1.8 branch commits shown) might help
here:
commit 665aa7ce8645b50b888db32ebab4e192dbe00649
OS support: fix writeable client vs IgnoreClient behavior
commit 090d26723f7cdbb3aebfe212170b7f81c163dd7b
dixstruct: make ignoreCount change more ABI friendly
2.6.34 introduced some new features, and X will test for them and use
them if available. However, the server's handling of clients was buggy
with the new code, which could cause clients to hang after VT switch,
waiting to be woken up.

If if matters, I saw such messages in the server log when the hang
happened:
[mi] EQ overflowing. The server is probably stuck in an infinite loop.

This entry should remain on the regression list.
In my opinion, we should apply Graham's patch from comment 8:
https://bugzilla.kernel.org/attachment.cgi?id=26508
which turns on "pci=use_crs" for this machine.
BIOS is telling us what configuration works, and we should
pay attention to it. amd_bus.c has no hope of ever discovering
this working configuration.

* x86/pci Oops with CONFIG_SND_HDA_INTEL

To: linux-kernel
Hi,
I am on x86_64 with latest (v2.6.34) kernel. When i set
CONFIG_SND_HDA_INTEL=Y It hangs at an early stage in boot with kernel oops.
When i use CONFIG_SND_HDA_INTEL=M the machine will boot, and i get the
dmesg (below).
I have bisected down to one commit that causes the problem:
commit 3e3da00c01d050307e753fb7b3e84aefc16da0d0
x86/pci: AMD one chain system to use pci read out res
...
I have reverted this in my current kernel (v3.6.34) and it seems to work
OK like this.
Is it possible to get this commit either removed, or amended to work
with SND_HDA_INTEL ?
OOPS from dmesg

I'm guessing these VIA chipsets are pretty common; how common is the
platform bug you fixed with 3e3da00c?
I'd rather quirk one platform than a whole bunch...

This is voodoo kernel development, and I don't think we should do it.
Can you explain the cause of Graham's oops? All I can see is that we
discovered a host bridge window of [mem 0x80000000-0xfcffffffff] to
bus 00, we did *not* find a bridge leading to bus 80, we found a device
on bus 80 that is inside the window forwarded to bus 00, so we moved
that device outside the window:
bus: 00 index 1 [mem 0x80000000-0xfcffffffff]
pci 0000:80:01.0: reg 10: [mem 0xfebfc000-0xfebfffff 64bit]
pci 0000:80:01.0: address space collision: [mem 0xfebfc000-0xfebfffff 64bit] conflicts with PCI Bus #00 [mem 0x80000000-0xfcffffffff]
pci 0000:80:01.0: BAR 0: set to [mem 0xfd00000000-0xfd00003fff 64bit]
I have no idea why this led to a page fault at ffffc90000078000:
BUG: unable to handle kernel paging request at ffffc90000078000
IP: [<ffffffffa0018d11>] azx_probe+0x3a2/0xa6a [snd_hda_intel]
It looks to me like amd_bus.c just failed to discover the host bridge
to bus 80. If the BIOS can program the chipset to work that way, we
should be able to figure that out, too.
Graham, I think your "pci=earlydump" log is missing the KERN_DEBUG
output. It would be interesting to see that for the patched kernel
so we can compare it with 2.6.34.

I think the basic problem is that Yinghai's patch broke your system,
and this is a regression between 2.6.33 and 2.6.34.
We could use a quirk like yours (which looks fine, BTW) to cover up
this regression, but I don't like that approach because other machines
are probably affected by the same issue, and we'd have to find and
fix them one-by-one.
I think it'd be better to figure out the problem with 3e3da00c01d
and fix or revert it. I said earlier that I wasn't in favor of just
reverting it, and I still don't like that option because it will
likely break something. But Yinghai didn't supply any details about
the system that 3e3da00c01d fixed, so I don't know how to fix things
so both that system and yours work.
I assume that 2.6.34 with 3e3da00c01d reverted will work fine even
without "pci=use_crs". Can you try that and attach the dmesg log?

[If you haven't been following this bug, the report is at [3].]
Here's a theory. I'm not an expert in HyperTransport, so maybe somebody
who knows HyperTransport and/or VIA chipsets can validate or refute it.
This is based on the _HyperTransport I/O Link Specification_, rev 3.10b [1],
and the _BIOS and Kernel Developer's Guide (BKDG) for AMD Family 10h
Processors_ [2].
In a nutshell, I think the problem is that amd_bus.c treats a
HyperTransport (HT) host bridge as though it were a PCI host bridge. In
particular, when an HT chain contains more than one PCI host bridge, the
HT host bridge apertures encompass all the PCI host bridges, but
amd_bus.c mistakenly assigns all those resources to one PCI host bridge.
>From a software point of view, HyperTransport is similar but not
identical to PCI. It is possible to make native HyperTransport
peripheral devices, but PCI devices must be attached via a
HyperTransport-to-PCI bridge [1, sec 4.1].
A PCI host bridge has a platform-specific non-PCI connection, e.g., a
front-side bus, on the primary (upstream) side and a PCI bus on the
secondary (downstream) side. Note that in the HyperTransport spec,
"host bridge" refers to the interface from the host, e.g., CPU cores, to
a HyperTransport chain. This HyperTransport host bridge has a
HyperTransport link on the secondary side, *not* a PCI bus.
A HyperTransport-to-PCI bridge is one kind of PCI host bridge, because
the primary side is HyperTransport and the secondary side is PCI.
Graham's machine contains one HT host bridge leading to an HT chain, and
it has PCI devices on buses 00, 02, 03, 06, and 80. In addition, the HT
host bridge configuration registers appear at device 18 (hex) in bus 00
configuration space, though they are not actually PCI functions. PCI
buses 02, 03, and 06 are reachable from bus 00 via the PCI-to-PCI
bridges at 00:03.3, 00:03.2, and 00:02.0, respectively.
However, there are no PCI-to-PCI bridges that lead to bus 00 or bus 80,
so the HT chain must contain two separate PCI host bridges that lead to
them.
Now, here's the problem: amd_bus.c reads the HT host bridge configuration
and learns that it routes buses 00-ff and the related address space,
including the following range, down the HT chain at node 0, link 0:
[mem 0x80000000-0xfcffffffff]
That makes sense, because both PCI host bridges are on that HT chain, so
the HT host bridge has to forward all that address space. The problem
is that amd_bus.c assumes there's only one PCI host bridge on the
chain, so it assigns *all* that address space to PCI bus 00.
This doesn't work because parts of that address space belong to bus 80,
not bus 00, and we can't reach bus 80 from PCI bus 00. In particular,
we know that at least the following address space is routed to bus 80,
because the 80:01.0 device does work at this address, which is in the
middle of the range we found above:
[mem 0xfebfc000-0xfebfffff]
(Note that we can reach bus 80 from the HT chain, but the HT chain is
outside the PCI domain, even though some of the HT registers appear in
PCI bus 00 config space. We need a second PCI host bridge from the HT
chain to PCI bus 80.)
The HT spec does suggest that an HT/PCI host bridge should implement a
HyperTransport Bridge Header [1, sec 7.4]. This header would make the
HT/PCI host bridge look just like a PCI-to-PCI bridge, with the usual
primary/secondary/subordinate bus numbers, memory, prefetchable memory,
and I/O port apertures, etc.
If all the HT/PCI host bridges on a chain were implemented this way, I
think it probably would work to pretend the HT host bridge is a PCI host
bridge. But this sort of implementation is apparently not universal.
The VIA chipset in Graham's machine doesn't do it that way, and the
Serverworks HT-2100 chipset in the HP DL785 doesn't either.

I don't think so. that system only have one HT chain.

the (0xe4) = ff 00 00 03
mean it will route pci operation all to node0 link0.
that chip from VIA has some design problem that will produce one orphan device.

This patch apparently does cover up the problem, but it fails on
so many levels:
- incomprehensible summary
- no changelog
- no bugzilla pointer
- unrelated junk in patch ("tmp")
- completely unexplained change to generic resource.c
- no indication that we understand the root cause

I think the best long-term fix is to always enable "pci=use_crs",
regardless of the BIOS date (currently we only do it for 2008 and
newer). System designers and BIOS writers expect the OS to pay
attention to that information, and indications are that Windows
does use it, so I think we will ultimately be better off if we
use the expected, best-tested path.
However, we have at least one known Linux issue (bug #16228) when
_CRS is enabled, so I'm hesitant to enable it unconditionally at
least until that is resolved.
In the short term, I think we should apply Graham's quirk from
comment #8, which enables pci=use_crs just for his system.
Here's my response to Yinghai's patches. ACPI gives us these resources:
pci_root PNP0A03:00: host bridge window [mem 0x80000000-0xff37ffff] (bus 00)
pci_root PNP0A08:00: host bridge window [mem 0xfebfc000-0xfebfffff] (bus 80)
Yinghai's patch (comment #17, with a v2 posted to the list but not in
the bugzilla), gives us these resources:
pci_bus 0000:00: resource 5 [mem 0x80000000-0xfcffffffff]
pci_bus 0000:80: resource 5 [mem 0x80000000-0xfcffffffff]
I think it's just a bad idea to assign the same range to both buses,
especially when the BIOS is telling us what we should be using.
I also think it's a mistake to mess with the resource code to deal
with this specific case. A change like that makes resource.c hard
to understand and maintain in the future.
