[Bug 109762] [AMDGPU] flip_done timed out when playing Xonotic

[bugzilla-daemon]

[-- Attachment #1.1: Type: text/plain, Size: 1435 bytes --]

https://bugs.freedesktop.org/show_bug.cgi?id=109762

--- Comment #1 from Amadeusz <amade@asmblr.net> ---
So as I half remembered it didn't happen in the past.

I did some internet searches and there are few similar bugs on this bugzilla:
https://bugzilla.freedesktop.org/show_bug.cgi?id=109461
https://bugzilla.freedesktop.org/show_bug.cgi?id=104624
https://bugzilla.freedesktop.org/show_bug.cgi?id=108309

But also I found:
https://bbs.archlinux.org/viewtopic.php?id=239670
which allowed me to narrow the time when it broke.

I looked at changes between 4.14 and 4.15 and choose to try reverting one of
the commits with "flip" as part of commit message. (Getting bisect running on
4.14 with too new gcc is pain...)

So seems like reverting 320a127437e5d3cbb7fc444f8769eb510d11d3b9 helps with
random freezes for me (although I tested only for one day).

However from what I can see reverting this commit is just a workaround...

So if anyone wants to try and reproduce it you can install Xonotic from
xonotic.org (or your distribution repositories) and either have some fun
playing or just create infinite time match with bots and once click left mouse
button after it starts to select bot view and leave it running.
One note that I start xonotic from command line with vblank_mode=0 added
before, like "vblank_mode=0 xonotic".
