It's a long shot, but does https://lists.freedesktop.org/archives/mesa-dev/2016-August/127318.html fix it?

I can confirm on R9 390, this patch stops the GPU page faults in dmesg log, but I'm still getting major corruption when recording the screen in obs or ffmeg https://youtu.be/pFqhIGYLbDM

Revert this patch to fix VDPAU corruption:

"radeonsi: increase performance for DRI PRIME offloading if 2nd GPU is CIK or VI" 5ee3cac1380fec6971e9d25267589a586da0ecd8.

I reverted this, rebuilt mesa, ran the ffmpeg command, played it back, the first 4 seconds is corrupt in the same way as before, then it's fine.

Rebuilt obs-studio, the window now shows an uncorrupted screen! REbuilt ffmpeg and no corruption.

This issue wasn't limited to mobile Bonaire. One interesting hint from bug 97610 is that it works fine with the radeon kernel driver, so maybe it's related to addrlib or the amdgpu winsys.

Anyway, fixed for now in Git master. Note that you need to start X with the fixed Mesa, because it affects glamor as well.

Revert "radeonsi: enable SDMA on CIK"

I can confirm this fixes the corruption I've reported in bug 97610.

Since Marek mentioned in the commit message of the revert, that it's maybe some tile configuration issue, I was wondering if Tom was correct in bug 97610, comment #1? Should I do the test – obviously with the revert undone – with the tiling configurations copied from radeon (bug 97610, comment #2)? Or is this something else?
