Description Jan Bertran 2015-10-02 08:03:48 UTC 
After several minutes or hours run time the OpenGL application gets stuck, no more rendering.
ssh session is alive and system can be inspected.
cat /sys/class/drm/card0/error --> "no error state collected"

System is ITX board with Intel N3150 cpu/gpu, dual monitor setup same resolution on each one with half of framebuffer shown on corresponding monitor.
Compositor is disabled.

Application is OpenGl fullscreen-"fullframebuffer" so page flip is active.
Linux:
  Kubuntu 15.10 beta updated at 1 october 2015 and with following git packages
Kernel: 4.3.0-994-generic #201509302200 SMP Thu Oct 1 02:02:04 UTC 2015 x86_64
package: http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-nightly/current/
linux-image-4.3.0-994-generic_4.3.0-994.201509302200_amd64.deb

libdrm: from https://launchpad.net/~xorg-edgers/+archive/ubuntu/ppa/+packages
with release libdrm-intel1:amd64                           2.4.65+git20150922.f3c6740f-0ubuntu0ricotz~vivid amd64

Other linux versions tested: releases of Kubuntu 14.10, 15.04 and 15.10, Fedora 22.
Other Intel HW tested: ITX boards with J1900 (similar results but variable state, sometimes system remains accessible from network, others is completely frozen)

The hang cannot be reproduced with single monitor setups.

There are several other bugreports similar but as kernel messages are not the same and this report is only about dual screen I'm opening this one...

Also I have done a hacked-modified glxgears version to make it more similar to my OpenGl usage, the result is the same but it takes a bit longer.

Comment 3 Jesse Barnes 2015-10-05 22:14:19 UTC 
Can you attach to the hanging processes with gdb -p and check the backtraces?  If we're not seeing a GPU hang, the process must be hanging on something else, maybe waiting for an event or potentially a locking problem in the kernel (sysrq-t would help track that down; depending on your kernel config that's easy or hard to do; best google around for your specific distro instructions).

Comment 7 Chris Wilson 2015-11-12 17:24:21 UTC 
If you can gather cat /sys/kernel/debug/dri/0/i915_gem_pageflip and an Xorg.0.log from xf86-video-intel compiled with --enable-debug=full, that should be enough information to pinpoint the blame.
Comment 8 Ben Widawsky 2015-11-13 01:29:23 UTC 
Jan, have you attempted to reproduce this without OpenGL involved?
Comment 9 Jan Bertran 2015-11-13 11:57:08 UTC 
First a bit of history about the issue.
One year ago we tested our games in single screen mode under Kubuntu 14.10 and
J1900 system. It worked for weeks without any issue.
Then an update on xf86-video-intel always produced a hang and always in a few 
seconds. We went back to original xf86-video-intel file.

Later we started making dual screen versions of our games.
The window setup keeps being similar. The app window covers whole framebuffer,
single OpenGl context (No compositor) and page flip gets activated as in single 
monitor setup. Then started to happen graphics frozen issues. We have tried
for several releases of Ubuntus (15.04 15.10 kernels 3.10, 4.1 4.2 4.3) and 
Fedora 22 with same result but different behavior and time to hang
(some could be recovered switching to console vt and back to X, others left 
system unusable).
Lately all hangs on J1900 left system totally inaccessible so I switched 
testing to N3150.

About test without OpenGL I'm not sure to understand.
I'm not sure how to test page flip without OpenGL or maybe you suggest 
that depending on the gpu load the behavior can change.
I think so, our game needs less time to hang than a test application I made 
based on glxgears.
Also about timing we setup frame rate to 30fps (60 Hz monitor and 
glXSwapIntervalMESA(2) or glXSwapIntervalSGI(2) )
While almost all applications just sync to VBlank with no divisor, so this 
could be an uncommon case.

The last tests done are under Kubuntu 15.10 with kernels 

linux-image-4.3.0-994-generic_4.3.0-994.201510162200_amd64 and 
libdrm2_2.4.65+git20150922.f3c6740f-0ubuntu0ricotz
and more recently with
linux-image-4.3.0-994-generic_4.3.0-994.201511052100_amd64 and 
libdrm2_2.4.65+git20151026.c745e541-0ubuntu0ricotz

And with latest updates I have a problem: the test application does not hang 
(at least for 3 days) without "drm.debug=0x1e"
but it does hang when drm debug is enabled, our game instead keeps hanging in 1 
day regardless of drm debug.
It seems also that if intel_gpu_top is running on an ssh terminal graphics hang in much less time.
Maybe system/gpu load influences on some race condition ?
Test app is just glxgears hacked with dummy textures and more gears and window 
setup using all display size, but our game usually is on the limit of 30fps (sporadically goes down to 20fps).

Next week I will do requested tests of xf86-video-intel with debug enabled, and 
later a test app that just fills framebuffer with single color.
At the moment cat /sys/kernel/debug/dri/0/i915_gem_pageflip gives

Thanks. We're trying to narrow down the cause of the underlying issue. I was trying to determine if this can be reproduced without mesa. It sounds like you've been able to reproduce it without your game, which is a good start. Would you be able to post your glxgears based application?

source code of modified glxgears

Attached a hacked version of glxgears:
Main modifications (just quick hacks):
- force frame rate divided by 2 (if 60Hz monitor 30fps)
- force run only if desktop resolution is double the width one of typical resolutions (for example 1920*2 x 1080 or 1600*2 x 900 ...)
- undecorated, stay on top window. No fullscreen hint as it would make go to only one monitor, problem with some window managers the panel/menu bar is visible (deactivating page flip)
- textures generated by program with alpha channel to "stress test" and more gears.
Build with
gcc  -o "glx_swapbuf_test"  ./glxswapcontrol.c   -lm -lX11 -lGL -lGLU
Time to hang can be as much as 2 days usually less than 1 day.
Last hang with kernel linux-image-4.3.0-994-generic_4.3.0-994.201511052100_amd64 both with and without drm debug enabled.

I have compiled xf86-video-intel with --enable-debug=full but it makes crash kde-plasma desktop. 
I'm trying to start app with other window managers or without any (xinit + shell script with xrandr) but in both cases I only get visual artifacts, (giant fragments of gears).
There has to be something missing in X startup sequence/permissions.

Thanks.

finally running with xf86-video-intel debug full Xorg log

contents of 
/sys/kernel/debug/dri/0/i915_gem_pageflip:
No flip due on pipe A (plane A)
No flip due on pipe B (plane B)
No flip due on pipe C (plane C)

Attached fragments of Xorg.0.log file

With debug full, the assert crashes in minutes/seconds.
Now running the test with UXA instead of default SNA
cat /etc/X11/xorg.conf 
Section "Device"
        Identifier "Intel UXA"
        Driver  "Intel"
        Option "AccelMethod" "UXA"
EndSection

First difference: there are no debug messages from xorg_video_Intel.

2 days working, UXA seems valid workaround (at least with linux-image-4.3.0-994-generic_4.3.0-994.201511052100_amd64.deb)

for me, next tests pending xf86-video-intel from git instead of ubuntu release and sna enabled, and maybe J1900 instead of N3150.
Comment 16 Jan Bertran 2015-12-01 07:56:12 UTC 
N3150 with SNA and latest git (2015-11-22) keeps blocking on page flip events.
N3150 with UXA works OK.
J1900 keeps hard-locking both with UXA and SNA.
(in both cases multimonitor setup)

Jan, Ben - is this issue still valid on newer kernels? There have been 1 year of silence...

In my opinion bug could be closed on Gen8 graphics as the problem with Celeron N3150 was in the X11 SNA driver and not in the kernel.
About Gen7 J1900 I have not tried anymore.
