Hello Christian,

you've made your 'homework'...;-)

No, I haven't.
It was fallen into the cranks of the repeated DC rebase of Alex's
'amd-staging-drm-next' tree (didn't noticed it for the last 7 days, Alex
vacation). 
I'll make it short. NO that didn't solve it for me, too.

But _this_ patch is GOLD:
drm-amdgpu-fix-VM-sync-with-always-valid-BOs.mbox

Tested-by: Dieter Nützel <Dieter@nuetzel-hh.de>

Best 'glmark2' Score I've ever seen.
RX580, 8 GB
Xeon X3470, 4/8, 3 GHz
24 GB

glmark2 Score: 6428

with additional load on the gfx cores through parallel running
'opencl-example/run_tests.sh' I got

glmark2 Score: 7574

Good job!
