amdgpu error message

Hi,

i upgraded from mainline kernel 4.19.7 to 4.20-rc5.
Sadly using that kernel the system freezes when it tries to show gdm.

OS: Ubuntu 18.04.1

Kernel:
Linux version 4.20.0-042000rc5-generic (kernel@gloin) (gcc version 8.2.0

I attached an .txt file showing more of the error messages.

I also have seen freezes with 4.19.7 with a similar error message, but this
happens very rarely. With 4.20-rc5 the issue happens every time gdm tries to
start, which makes the system unusable.

If you need any other info, please ping me.

Many thanks !
Christian

I have the same issue with a 2700U in a Dell Inspiron 7375. All of the 4.20 RC
versions that I have tried show the same problem. The system is able to boot
with a 4.19 kernel.

Can you boot the system without amdgpu loaded (e.g., append
modprobe.blacklist=amdgpu)?  Or is this a general platform problem?

To clarify, the system can boot with the amdgpu module, but it will lock up
when LightDM/X starts. Booting with the amdgpu module blacklisted works.

Yes, same here. The system boots until GDM wants to start, then it freezes with
the mentioned amdgpu error. Disabling amdgpu let the system start up completely
including gdm.

020aa2ec15fc4a5ffdfcab7dc0db648a137abc41 lets me log in before the system
freezes.

770af5859d6903049b7f39ed4f4e6612b63fd82d locks up before LightDM can start.

I'll do a bit more testing.

Ignore that previous comment. I'm getting some strange results here and may
have marked a commit with an intermittent crash as "good" while bisecting.

Well, that's kind of useless.

Any suggestions on how to get a better idea of where the break was?

FYI, as a workaround, you can use the kernel opt:

 iommu=pt

..at least, on 4.20 rc7, which is the only one I've tried that on, but it
should work with others.

I can confirm that the iommu=pt workaround works, also iommu=soft works to get
gdm started and use the laptop. Sadly i have no idea what impact those
workarounds have when it comes to performance of the gpu/cpu or battery
lifetime ?

Sadly i had a freeze during desktop usage shortly after boot using iommu=pt.
The driver situation for raven ridge is really sad atm :( .

I've tested a next-20181221 kernel with IOMMU_DEFAULT_PASSTHROUGH set, and I'm
able to get the system to start properly. Still seeing some system lockups,
when playing games, but it's better than crashing on the login screen.

Hi,

the laptop is still freezing when trying to start with kernel 4.20 (release
version) using latest amdgpu firmware from kernel firmware git.

Using iommu=soft still solves that issue.

I also tested with a kernel daily build from 26.12 which should include the
latest drm changes, and it also shows the same issue.

Is there anything we can provide to help finding the root cause ?

Many thanks !
Christian

Seeing same issue with Dell 5575 (AMD 2500u, Vega mobile) on 4.20 Release. 
iommu=soft seems to allow boot.

With iommu=soft I still occasionally experience frozen screen with following
logs:

I would like to add that on my Lenovo E585 iommu=pt works reliably; even for
hours and doing games/webvideos. But a few minutes in wayland produce a frozen
screen (without iommu=pt is does not even start).

No problem here with amdgpu and iommu enabled, running kernel 4.20.0 on Dell
Latitude 5495 (2700U). So BIOS issue maybe?

iommu=pt is however still needed for kfd (bug 107898).

journalctl -b of lockup from bisected commit

E585 owner here.  Please let me know if I can provide any additional
information that would be helpful.  Thanks in advance for your help.

This problem was very consistently reproduced during the bisect.  I've attached
a journalctl -b from the first bad commit.  I was able to bisect the problem
to...


284dec4317c8e76f45d3ce922f673c80331812f1 is the first bad commit
commit 284dec4317c8e76f45d3ce922f673c80331812f1
Author: Christian König <christian.koenig@amd.com>
Date:   Wed Aug 22 16:44:56 2018 +0200

    drm/amdgpu: enable GTT PD/PT for raven v3

    Should work on Vega10 as well, but with an obvious performance hit.

    Older APUs can be enabled as well, but will probably be more work.

    v2: fix error checking
    v3: use more general check

Hi,

many thanks for that bisect.
I googled the commit and found the following in addition which seems to be the
same issue ?

https://bugzilla.kernel.org/show_bug.cgi?id=201727

Hope that helps.

Many thanks !
Christian

Still the same issue with kernel 5.0-rc1. Any plan on when to tackle that issue
?

I'm able to boot when building from that commit (1c1eba8) and looks like it
will land in 4.20.4.

Thanks!

Very nice. Just tried 5.0-rc2 and booting works fine now without the iommu
workaround !
