dmesg

Hello,

After fixing https://bugs.freedesktop.org/show_bug.cgi?id=109107, hardware
decode on Ryzen 2700u started working again.

However, at the next update at mesa git 67426cc the GPU is hanging completely
if I try to watch videos on chromium-vaapi, with the following error:

[  215.259576] amdgpu 0000:04:00.0: [mmhub] VMC page fault (src_id:0 ring:40
vmid:5 pasid:32770, for process chromium-vaapi pid 2877 thread chromium-v:cs0
pid 2946)
[  215.259583] amdgpu 0000:04:00.0:   in page starting at address

[  225.212466] [drm:amdgpu_job_timedout [amdgpu]] *ERROR* Process information:
process chromium-vaapi pid 2877 thread chromium-v:cs0 pid 2946


Graphical interface is hanged completely however music keeps hanging in the
background, so I was able to ssh into the system and dump the dmesg log.

Fedora repos:
che-mesa, rpmfusion, fedora-rawhide-kernel-nodebug
Mesa-git installed is build from: sha 67426cc


Full dmesg log attached.

--- Comment #1 from Michael Eagle <xanto@egaming.ro> ---
Same behavior happens with both:
kernel-5.0.0-0.rc4.git2.2.fc30.x86_64
kernel-5.0.0-0.rc6.git1.2.fc30.x86_64


Downgrading the kernel to official fedora '4.20.7-200.fc29.x86_64' makes the
system not to crash anymore, however the video is very scrambled, as part of it
would play in a loop.

Disabling 'hardware accelerated video decode' in chrome://flags/ fixes the
issue.

Hello,

Sorry for the late reply, I've just tested it using mesa git SHA 138865e ,
which includes this commit. And the issue seems solved.
I suppose this can be closed now.
Thank you much!
