so guys,
I can't believe that nobody hits this: Since -rc1 Nautilus' list of
elements or Firefox' website window or just photos in eog (probably
among many more things) is mangled. Please have a look at the screenshot
of nautilus.
This is the same on a i3 laptop with intel graphics and a i7 with nouvau
graphics. I bisected and the problem is this merge:
first bad commit: [56e520c7a0a490b63b042b047ec9659fc08762a4] Merge tag
'iommu-updates-v4.9' of
git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Two things I'd ask of you if this isn't already a known problem to you:
* I failed bisecting into this merge but I could easily have tried it
totally wrong, so I'd appreciate any advice on how to bisect into this.
Strangely, running joro's
https://git.kernel.org/cgit/linux/kernel/git/joro/iommu.git/commit/?h=iommu-updates-v4.9&id=13a08259187c5cd3f63d98efa159ab42976d85a4
(referenced here:
https://git.kernel.org/cgit/linux/kernel/git/joro/iommu.git/tag/?h=iommu-updates-v4.9)
is good (?)
* Please add anybody you know is involved to CC.
I'm happy to test patches too, of course.
Anyhow. This is a bad regression that prevents me from running 4.9. Just
so you know.
so long,
martin

Can you please send a boot-dmesg and 'lspci -v'? We need more
information about your system first.

This is one machine booting a bad kernel. I could provide another
example later this week.

You have an Intel system without any IOMMU (enabled), otherwise you
would have a DMAR-ACPI table, but there is none:

So it is pretty unlikely that any change in IOMMU code causes your
issue. Not sure why your bisecting ended up there. You also have an
Intel GPU in the system:

My best guess is that some changes in the i915 driver cause your issue,
I add the maintainers of i915 to the cc-list, maybe they have an idea.

I'll come up with a nouveau system example and it was quite easy to bisect. To quote the merge commit msg:
This also required some changes outside of the IOMMU code, but these are acked by the respective maintainers.
Any help on bisecting into it would be awesome.

So the information here is pretty scarce. Please file a bug at [1],
describe the problem, perhaps add drm.debug=14 module parameter and
attach dmesg from boot to reproducing the problem.

Martin, did you do that and can point me to the bug? And if not: Any
news on the issue?
FWIW: I added this report to the list of regressions for Linux 4.9. I'll
watch this thread for further updates on this issue to document progress
in my weekly reports. Please let me know via regressions@leemhuis.info
in case the discussion moves to a different place (bugzilla or another
mail thread for example).
tia! Ciao, Thorsten

I did not file a bug in bugzilla yet. I haven't given up that we can fix
this here before the release. I've ignored it the last few days though.
Again: This is the first bad commit:
[56e520c7a0a490b63b042b047ec9659fc08762a4] Merge tag
'iommu-updates-v4.9' of
git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
If you know how to bisect into this, please share your thoughts. Linus'
merge here is bigger than iommu-update-v4.9 i think and that's what I
have to look at really. I'm not sure how though.
One part of the merge is indeed iiommu-updates-v4.9:
That's the tag:
https://git.kernel.org/cgit/linux/kernel/git/joro/iommu.git/tag/?h=iommu-updates-v4.9
and the tagged object:
https://git.kernel.org/cgit/linux/kernel/git/joro/iommu.git/commit/?h=iommu-updates-v4.9&id=13a08259187c5cd3f63d98efa159ab42976d85a4
I'll have to think about how to check the iommu-updates-v4.9 part of the
merge again... to eliminate something.

You say it like filing the bug report and having the bug fixed are
mutually exclusive things...
Pretty please? It's easier for us to direct folks at the bug, with
history and logs in one place. I realize only Daniel and me were Cc'd
here, not intel-gfx list.
Also, please double check your bisect. Not sure why the finger points at
i915 when the bisect points at iommu merge.
BR,
Jani.

Hi Martin.
I can't contact you through LKML because I'm not subscribed, but I've
been working with Chris Wilson, one of the Intel
DRM developers to analyse and fix the corruption. We've got a patch that
fixes it for me and Norbert who also reported
the problem. The patch is at the bottom of this message.
Hope it helps.
Chris

That's just the enabling patch, everything was meant to be in place by

With 4.9-rc4 I have corruptions that look like the ones reported in this
thread.
I reported my finding on LKML thread about 3.9-rc4. And in Bugzilla in a bug
report with an attachment that shows the same type of corruptions as here in
this thread:
https://patchwork.freedesktop.org/patch/116808/
mentioned in the other bug report and the following LKML thread does not fix
the issue for me:
Re: [REGRESSION] Linux 4.9-rc4: gfx glitches on Intel Sandybridge (was: Re:
Linux 4.9-rc4)
https://lkml.org/lkml/2016/11/6/70
https://bugzilla.kernel.org/show_bug.cgi?id=177701#c4
In my case it looks like this:
https://martin-steigerwald.de/tmp/display-issues-with-kernel-4.9-rc4.png
I have a busy week, so I won´t to any bisecting at the moment. I am happy to
test another patch during breaks between holding the training, but please
point me specifically to what patch to test. Thank you.
In general I am a bit confused about:
1) when do I use the bugtracker
2) when to just post on LKML
3) and which bugtracker to use? bugzilla.kernel.org versus the freedesktop one
in this case. See:
http://lkml.iu.edu/hypermail/linux/kernel/1611.0/03126.html
4) how to determine whether a bug report matches my case or not. In that case
its easy enough considering the screenshots.
(using this list archive as threading view in lkml.org seems broken)
This bug is already being discussed in three places right now, I bet it makes
sense to settle on one place. I´d opt for Bugzilla but I would like to use my
MUA to access it for simple comments.
Thanks,
Martin

That bug conflates two issues, with the main issue being unrelated to
corruption.

As I wrote in another thread, the fix has now been pushed to
drm-intel-fixes branch of http://cgit.freedesktop.org/drm-intel. It's
-rc4 plus half a dozen fixes, including "drm/i915: Round tile chunks up
for constructing partial VMAs" which should fix the corruption.
Please try that, and report back. If it doesn't fix the issue, please
file a bug at the freedesktop.org bugzilla.
BR,
Jani.
