The patch has been included in amd-staging-drm-next for a while, should this
bug be closed?

I confirm that bug 102500 and bug 102598 are the same.

I split up the patch into 3 parts and they applied cleanly with offsets to
drm-next-4.15-wip.

I then reverted mesa to commit 214b565bc28bc4419f3eec29ab7bbe34080459fe
(winsys/amdgpu: set AMDGPU_GEM_CREATE_VM_ALWAYS_VALID if possible v2) compiled
and started X and corruption and lockups are gone.

Bug 102500 might be related to bug 102598.

I tried to apply patch attachment 134082 to  amd-staging-4.12 (~agd5f/linux)
kernel and drm-next-4.15-wip but it does not apply cleanly.  I applied it
manually to drm-next-4.15-wip and that kernel would not finish compiling.

I can confirm that after applying the patch the issue doesn't occur for me. (I
hope that's enough, I can't claim more than that since I have done 2-3 upgrades
of mesa/llvm since I last tested the broken kernel.)

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 

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!

Patch fixes issue.
I've tried both staging-4.12 and staging-drm-next branches.
Thanks Christian

PS. It will be nice if Vedran could confirmed this for Vega before we close.

No problem, that just means that this is the same issue I'm still hunting for.

Christian sorry, I thought that was clear. 
Yes, I updated ASAP so it contains:
https://cgit.freedesktop.org/~agd5f/linux/commit/?h=amd-staging-4.12=8bd2cc0ab44b00346cc41f3ac828cbf992f6bc61
Doesn't help for vm-faults

Every test right before and after your comment is for:

To repeat my question: Does patch "drm/amdgpu: fix moved list handling in the
VM" fix the issue?

Do you guys have this in your kernel branch yet? If not that lockup is
expected.

on mesa side looks like this is it:

214b565bc28bc4419f3eec29ab7bbe34080459fe is the first bad commit
commit 214b565bc28bc4419f3eec29ab7bbe34080459fe
Author: Christian König 
Date:   Tue Aug 29 16:45:46 2017 +0200

winsys/amdgpu: set AMDGPU_GEM_CREATE_VM_ALWAYS_VALID if possible v2

When the kernel supports it set the local flag and
stop adding those BOs to the BO list.

Can probably be optimized much more.

v2: rename new flag to AMDGPU_GEM_CREATE_VM_ALWAYS_VALID

additional info:
I try figure out why in my earlier test everything went ok and probably mesa is
the trigger, 

Linux-amd-staging + Mesa-git + LLVM-svn - failure
Linux-amd-staging + Mesa-git + LLVM 4.0.1 - failure
Linux-amd-staging + Mesa 17.1.8 + LLVM 4.0.1 - works ok. 
I try later some bisecting, we will see.
