Description Adam Nielsen 2016-04-04 12:48:26 UTC
Created attachment 122700 [details] dmesg output after OOM event In response to this request: https://lists.freedesktop.org/archives/intel-gfx/2016-February/088489.html I have run the drm-intel-nightly kernel for 18 days, two hours and experienced this problem again. It usually manifests when using mplayer fullscreen (windowed is fine) at 2K or 4K resolution. The video framerate grinds to a crawl, mplayer spits out messages about the computer being too slow for playback, then applications start getting killed by the kernel OOM killer. The system has around 14GB of free memory at this point, so it's obviously not main memory it has run out of, although the kernel still tries to kill processes to free up main memory anyway. The mailing list post has copies of dmesg from a normal kernel, and I will attach copies of dmesg output for drm-intel-nightly. To produce this dmesg output, I ran mplayer in fullscreen mode at 4K (720p video), after a few minutes it ran slowly so I exited mplayer and observed one process was killed. I immediately launched mplayer again and it was slow from the start, and then when I exited I observed another process was killed. I can now no longer run mplayer as it will kill all my processes one by one, so to run mplayer again I will need to restart my machine. It almost seems like there is a video memory leak, video memory is becoming fragmented, or something along those lines. It always seems to take at least two weeks for the problem to surface. System architecture: x86_64 Kernel version: 4.5.0-1-drm-intel-nightly Distribution: Arch Linux Machine: Intel DH87MC motherboard, latest BIOS as of drm-intel-nightly compilation date (reflashed before booting this kernel) Display connector: DP@4K, DVI@1600x1200 portrait, HDMI@1600x1200 portrait I only just saw the request to use drm.debug=0x1e so I will add that to my kernel command line now and reboot in a day or two if I don't hear back with any more tests to run, and in another 18 days or so when the issue happens again I'll attach the more detailed logs.

No, it doesn't. That 14GiB are alloted to the video driver and still in use by userspace. The oom event says you have less than 100MiB of free pages available. cat /sys/kernel/debug/dri/0/i915_gem_objects.
Comment 2 Adam Nielsen 2016-04-04 13:24:49 UTC
Hmm, that's odd - how can I find out what is using 14GB(!) of video memory? $ cat /sys/kernel/debug/dri/0/i915_gem_objects 1045 objects, 5773352960 bytes 790  objects, 1170497536  bytes in gtt 22  active objects, 2465792  bytes 768  inactive objects, 1168031744  bytes 221 unbound objects, 4590669824 bytes 19 purgeable objects, 124370944 bytes 5 pinned mappable objects, 110055424 bytes 7 fault mappable objects, 171761664 bytes 2147483648  gtt total systemd-logind: 959 objects, 2850779136 bytes (2396160 active, 1024491520 inactive, 1026887680 global, 1767260160 shared, 1815900160 unbound) systemd-logind: 75 objects, 2954997760 bytes (0 active, 176033792 inactive, 176033792 global, 2742681600 shared, 2774769664 unbound)

Comment 4 Adam Nielsen 2016-08-11 00:26:22 UTC
I found some advice that recommended stopping using xf86-video-intel and letting it fall back to the default, and this has made the problem go away. I'm not sure what you lose by not using xf86-video-intel though, but it certainly avoids the memory leak. The GEM objects are now consistently well below 1GB after a month, instead of reaching 14+GB after two weeks.

Comment 6 Chris Wilson 2016-08-11 06:51:04 UTC
So basically your distribution chooses not to ship an uptodate driver.
Comment 7 Adam Nielsen 2016-08-11 09:11:29 UTC
I compiled the git version of xf86-video-intel as suggested on the mailing list and it had the same problem, so shouldn't be a problem with the distro. Why the WONTFIX? Is this driver being phased out?

Also, still having video corruption issues on fullscreen playback from bug 97037 and bug 97089 (I suspect those are related to each other; not sure if related to this bug, too) Please help, the driver is near unusable for me right now!

I'm experiencing the same thing on 4.7.0 + Skylake and I don't even have xf86-video-intel, because mesa + Wayland-only Gnome installation. The system has 32GB RAM. It strongly looks like something leaks somewhere. ...

Comment 11 Sérgio Martins 2017-05-16 14:24:00 UTC
What would move this bug forward would be a minimal C/C++ test-case. Having to run firefox or mplayer will probably make the developer move the bug priority down on his list.

Hello, closing this bug as not our bug. This bug was revised by email. The problem was a userspace bug already fixed. Oom report states userspace. If new problems arise, please file a new bug with HW&SW information and fresh logs. Thank you.
