Hi,
I think I've found a regression, which causes an early boot crash, I
appended the kernel output via jpg file, since I do not have a serial
console or sth.
after bisection, it boils down to this commit:
9dcd61303af862c279df86aa97fde7ce371be774 is the first bad commit
commit 9dcd61303af862c279df86aa97fde7ce371be774
Author: Alex Williamson <alex.williamson@redhat.com>
Date: Wed May 30 14:19:07 2012 -0600
amd_iommu: Support IOMMU groups
Add IOMMU group support to AMD-Vi device init and uninit code.
Existing notifiers make sure this gets called for each device.

We can see this is clearly wrong:
[ 1.486473] AMD-Vi: DEV_ALIAS_RANGE devid: 08:01.0 flags: 00 devid_to: 08:00.0
[ 1.486510] AMD-Vi: DEV_RANGE_END devid: 08:1f.7
So the BIOS is telling us to alias everything in the range of 08:00.0 to
08:1f.7 to device id 08:01.0, which doesn't exist :( Can you send lspci
-vvv? I suspect we'll find that 07:00.0 sources bus 08 and that alias
should really be to 07:00.0 instead of 08:01.0. Please also provide
dmidecode for this system, we may need to create a quirk for this box.
Thanks,
Alex

Sorry, messed up the alias, it's aliasing 08:01:0 - 08:1f.7 to 08:00.0,
which still doesn't exist. Otherwise it's still broken as described.
Joerg, do we have any quirk hooks to fix things like this? Thanks,
Alex

Yep, my guess appears correct, the alias should be to device 07:00.0.
It looks like this is a x1 PCIe card, so I think that PLX bridge is on
the card. The system probably boots fine if you remove the audio card
(or of course with amd_iommu=off). It looks like there is one rev newer
BIOS for this motherboard; we should probably exhaust the possibility
that this bug has already been fixed in BIOS 1503 before we implement a
quirk. Can you test this?
Joerg, any thoughts on a quirk for this? Unfortunately we can't just
skip IOMMU groups when an alias is broken because it puts the other
IOMMU groups at risk that might not actually be isolated from this
device. It looks like we parse the alias info before PCI is probed, so
maybe we'd need to call the quirk from iommu_init_device itself.
Thanks,
Alex

You might also try the sound card in different slots, it's possible the
BIOS only generates the wrong entry for the x1 slot. If you do try
this, please boot with amd_iommu_dump and report configuration and
AMD-Vi dmesg output as above. Thanks,

I fear that the BIOS does everything right and device 08:04.0 is indeed
using 08:00.0 as request-id. There are a couple of devices where this
happens, usually when the vendor just took the old 32bit PCI chip, added
a transparent PCIe-to-PCI bridge to the device and sell it a PCIe.
So the assumption that every request-id has a corresponding pci_dev
structure does not hold. I also had made that assumption in the
AMD IOMMU driver but had to add code which removes that assumption. We
should look for a way to remove that assumption from the group-code too.

Hmm, that throws a kink in iommu groups. So perhaps we need to make an
alias interface to iommu groups. Seems like this could just be an extra
parameter to iommu_group_get and iommu_group_add_device (empty in the
typical case). Then we have the problem of what's the type for an
alias? For AMI-Vi, it's a u16, but we need to be more generic than
that. Maybe iommu groups should just treat it as a void* so iommus can
use a pointer to some structure or a fixed value like a u16 bus:slot.
Thoughts? Thanks,
Alex

Assuming this works, it may be ok as a 3.7 fix, but if there was
actually more than one device behind the alias we'd expose them as
separate iommu groups. I don't think that's what we want. Maybe it
should at least get a pr_warn. Thanks,
Alex

True, we need something more generic as the real fix. When Florian
reports success I'll try to get this still into 3.6, otherwise to
-stable.

Good question. The iommu-groups are part of the IOMMU-API, with an
interface to the IOMMU drivers and one to the users of IOMMU-API. So the
alias handling itself should be a function of the interface to the IOMMU
driver. In general the interface should not be bus specific.
So a void pointer seems the only logical choice then. But I would not
limit its scope to alias handling. How about making it a bus-private
pointer where IOMMU driver store bus-specific information. That way we
make sure that there is one struct per bus-type for this pointer, and
not one structure per IOMMU driver.

I thought of another approach that may actually be more 3.6 worthy.
What if we just make the iommu driver handle it? For instance,
amd_iommu can walk the alias table looking for entries that use the same
alias and get the device via pci_get_bus_and_slot. If it finds a device
with an iommu group, it attaches the new device to the same group,
hiding anything about aliases from the group layer. It just groups all
devices within the range. I think the only complication is making sure
we're safe around device hotplug while we're doing this. Thanks,
Alex

it still fails with the card in a *different* slot.
But with the patch applied, everything works, so this fixes it for me! Thanks a lot. Output of the relevant parts of dmesg and lspci see below. I'll still try the newest BIOS rev. and report back.
thx, Florian

... updating to the newest BIOS revision does not make any difference, rc7 is crashing, rc7+patch is not, I definitely need this patch.
If there is more you want me to test, pls tell.

I think this could work. Instead of searching for other devices, check
for or allocate an iommu group on the alias dev_data, any "virtual"
aliases use that iommu group. Florian, could you test this as well?
Thanks,

Here's a lockdep clean version of it:
amd_iommu: Handle aliases not backed by devices
Aliases sometimes don't have a struct pci_dev backing them. This breaks
our attempt to figure out the topology and device quirks that may effect
IOMMU grouping. When this happens, allocate an IOMMU group on the
dev_data for the alias and make use of it for all devices referencing
this alias.

yes, this patch is working for me, too. I also tested your second patch, it was working as well.

Yes, this is the real fix. But it is too big for v3.6 at this time, so
I'll would take this for 3.7 and use my small fix for 3.6.

I think this lock is not necessary. The iommu_init_device routine does
not run multiple times in parallel for the same device. So we should be
safe on that side.
