            Bug ID: 205169
           Summary: AMDGPU driver with Navi card hangs Xorg in fullscreen
                    only.
           Product: Drivers
           Version: 2.5
    Kernel Version: 5.4.0-rc2
          Hardware: x86-64
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri@kernel-bugs.osdl.org
          Reporter: drjoms@gmail.com
        Regression: No

I have another problem logged with Navi + AMDGPU drivers. It's triggered
independently and reliable.
https://bugzilla.kernel.org/show_bug.cgi?id=204725

With that said, starting strictly and specifically with kernel version 5.4.0* I
have new problem.

I successfully load into Xorg. I can start OpenGL and Vulkan games in non full
screen. But once I start them - input devices hang, screen freezes. Machine is
responsive over SSH/ethernet. I can raise skinny elephants.

I tried opening a few games in non full screen mode and in full screen mode.
And i reliably hit bug everytime anything with OpenGL goes full screen on
native resolution of the screen.

I noticed, issue is less likely to happen if program goes full screen in non
native resolution.

I will attach details in files for DMESG, lsmod and some other things directly
as message, if they are short enough.

i realised that I have llvm 10 and 9 same time on my machine. i removed llvm
10, recompiled mesa.

uname -a
Linux (none)dimko's Desktop 5.4.0-rc2 #1 SMP PREEMPT Tue Oct 8 19:48:16 IST
2019 x86_64 AMD Ryzen 5 1600 Six-Core Processor AuthenticAMD GNU/Linux

I am on AMD64 Gentoo.

will test after mesa is recompiled with V9 LLVM support and report any changes.
If any.

interesting find, under Xwayland, same issue doesn't happen!
I won't blame it on Xorg, because under older kernel programs with OpenGL and
fulscreen work.

What kernel version were you using before that didn't have the problem?

It was 5.3.* when I could open and use OpenGL and Vulkan apps full screen and
it wouldn't crash. This is list of kernels I used from 5.3.*

ls /boot/ |grep vmlinuz-5.3. 
vmlinuz-5.3.0+
vmlinuz-5.3.0-next-20190920

i had a couple of LLVM versions.i removed all. Now I have version 9.0.0

 sys-devel/llvm
      Latest version available: 9.0.0
      Latest version installed: 9.0.0

I have recompiled Mesa with llvm 9(previously was compiled with llvm 10 which i
removed off the system manually)

"git bisect" identifies this commit as the problematic one: 617089d5837a
("drm/amd/display: revert wait in pipelock").

Reverting this commit on top of amd-staging-drm-next seems to work fine.

first introduced.

I had a similar issue with Borderlands 2:
https://gitlab.freedesktop.org/mesa/mesa/issues/2004


After I reverted the patch  mentioned in comment 10, the issue seems to be
fixed.
The other hang later seems unrelated (looks like sdma is the problem with that
one).

I don't know which games you mean. Some others work don't hang me, such as Ion
Fury, The Bard's Tale IV and etc. Yet some others like Hedon hang with
gfx_0.0.0 timeout hang, so not the same as flip_done timed out hang.

Anyway, I'll try reverting that commit, to check if it helps.

I tested many games all over. Many had this issue, some not. After reverting
the aforementioned kernel patch and installing latest llvm and mesa from git, I
had no more hangs (around 3-4 weeks without a hang now).

It did not just solve one problem, but two!

First of all it solved original issue.
Second of all, some games were hanging right before quitting.
Xorg was responsive, but processes did not disappear.

I was blaming on proprietary code.

Apparently it was same bug, just different invocation of it.

Please close this bug report. My problem is now fixed.

It fixes Pathfinder: Kingamer too. But first let the patch be upstreamed, then
it's OK to close the bug :)

I just let Borderlands 2 run for about one hour in the menu which causes a hang
without this patch in at most 3 minutes.

Consider Borderlands 2 also fixed with this :)

Just FYI, 5.4 is out, but the fix didn't land yet, so it needs to be still
applied manually.

Also, even with 100 ms timeout, the flip hang still happens just very rarely
and not in the usual scenarios for me. For example when playing The Witcher 3
(Wine+dxvk) and minimizing the game Window, on some rare occasion that flip
hang occurs even with the patch. I suppose it's something to do with KWin (I
usually keep compositing disabled though in those cases).

So may be 100 ms value is not always enough?

Kernel driver hangs in production using regular usage. Such issues should be
escalated as much as possible: DCN authors and developers meetings, core
developers replacements, driver refactoring/rewrite, tests coverage. But it
works in commercial environment only, open source provides
TIMEOUT_FOR_FLIP_PENDING.

1.5 years passed: TIMEOUT_FOR_FLIP_PENDING is still here and nobody cares, and
i am almost sure that nobody will care about it tomorrow.

Thank you.
