AMD-Vi regression with PCIe/PCI bridges in 4.4

AMD-Vi regression with PCIe/PCI bridges in 4.4

[Clemens Ladisch]

Hi,

there are several reports of Xonar PCIe sound cards failing to work in
kernel 4.4 (including 4.4.5):

https://bugzilla.redhat.com/show_bug.cgi?id=1313790
https://bugzilla.kernel.org/show_bug.cgi?id=111711
https://bbs.archlinux.org/viewtopic.php?pid=1601338#p1601338

They show error messages like this:

  AMD-Vi: Event logged [IO_PAGE_FAULT device=03:00.0 domain=0x0000 address=0x000000000020cf00 flags=0x0070]

All these cards use a PCI chip, with different PCIe bridges (ASM1083,
PEX8112, PEX8111).

It probably matters that "03" is the PCI bus, but that device "00" does
not exist.

Clemens

I have seen that before, can you please boot with 'amd_iommu_dump' on
the kernel command line and send me dmesg after boot?


Thanks a lot,

Hmm, with this IVRS table it should've never worked. For it to work
there needs to be an alias defined from device 05:04.0 to device
05:00.0. Otherwise the iommu driver doesn't know about the real
requestor-id it could expect from the sound card.

Did you do a BIOS update in-between? Or maybe some change to the sound
driver makes it misbehave and use a wrong pci request-id?

It did work before 4.4.  Is it possible that the IOMMU, or some feature,
got enabled by default?

Martin/Tomasz, could we get the amd_iommu_dump dmesg output for an
earlier kernel?

> Did you do a BIOS update in-between?

None of the three reporters reported this.

Switching between 4.4 and 4.3 makes the problem (dis)appear.
The problem must be connected with the kernel code.

The driver did not change at all, and the sound device is a plain PCI
chip.  The various sound card models use completely different PCIe/PCI
bridges (PEX8112 and ASM1083).

It's for 4.1.15. Both kernels were built with Gentoo patches but I don't
think they added anything in related areas. I can build vanilla kernels
if it would be better.

Hmm, is this reproducible without the propietary nvidia-driver loaded?

All those "iommu: Adding device x to group y" messages from 4.4 are
missing.

Apparently, something caused the IOMMU to be enabled.  Tomasz, could you
please compare the configurations (/lib/modules/(version)/build/.config)
with "diff -u" or something like that?

Yeah, these messages got added in v4.2.

Yes, I get errors also w/o nvidia module (attaching dmesg).

I did that before and couldn't figure out anything on my own. There is a
lot of noise due to new/changed options between 4.1 and 4.5. I don't
think I made any significant change in config (except make oldconfig).
Diff attached.

Sorry, I don't have access to that system at the moment and supply the
info as early as I get back home in 10 days. Please keep me in cc.

As for the other questions:

- no proprietary drivers installed
- no BIOS update

Martin

Hmm, pretty weird. Maybe I can get one of those cards myself to
reproduce it. Can you guys send me some more detailed information about
the sound cards that cause the problems? Vendor and exact product name
would be helpful.

Thanks,

I'm using Asus Xonar DX card: https://www.asus.com/Sound-Cards/Xonar_DX/

Let me add that I also did no BIOS upgrade in the meantime and I use no
other proprietary drivers other than Nvidia (which I already checked not
to be the source of the problem).

I use the Asus Essence STX II (the one withOUT the additional 7.1
surround card):

http://www.asus.com/Sound-Cards/Essence_STX_II/

I use it in its original configuration, without changing the op-amp
chip.

Most of the PCIe Xonar cards use the same architecture: a PCI chip and
a PCIe/PCI bridge.  Consider the Asus Xonar DGX, Xonar DSX, or Xonar DX.
(The D2X and STX are way overpriced.)

Okay, with this card I was able to reproduce the problem myself. Can you
guys please test if the attached patch fixes the issues for you as it
did for me?

Subject: [PATCH] iommu/amd: Fix checking of pci dma aliases

Commit 61289cb ('iommu/amd: Remove old alias handling code')
removed the old alias handling code from the AMD IOMMU
driver because this is now handled by the IOMMU core code.

But this also removed the handling of PCI aliases, which is
not handled by the core code. This caused issues with PCI
devices that have hidden PCIe-to-PCI bridges that rewrite
the request-id.

Fix this bug by re-introducing some of the removed functions
from commit 61289cbaf6c8 and add a alias field
'struct iommu_dev_data'. This field carrys the return value
of the get_alias() function and uses that instead of the
amd_iommu_alias_table[] array in the code.

Fixes: 61289cbaf6c8 ('iommu/amd: Remove old alias handling code')
