drm lockups on g965 hardware

[Peter Cordes]

Binary package hint: linux-source-2.6.20

 All Feisty needs to support 3D on Intel g965 hardware without frequent crashes or lockups is to use a newer version of the kernel drm drivers. It has i915 drm 1.6.0, but libdrm from git is currently at 1.9.0.

 Running feisty's AMD64 2.6.20-14-generic, and with X started in an AMD64 feisty chroot, some openGL programs can trigger a bug, and get a message like:
Apr 8 03:34:25 tesla kernel: [133430.971457] [drm:i915_wait_irq] *ERROR* i915_wait_irq: EBUSY -- rec: 16309404 emitted: 16312306

 And the X server exits, leaving the image on screen unchanged. re-starting X fails, because the hardware is confused. (A reboot, or at least a suspend/resume to re-POST the video is needed.)

 How frequently this happens depends on the program. Some games seem to trigger this within 15 minutes to an hour. Others not at all. I think it depends on what graphics effects are enabled, too. Anyway, currently feisty on g965 hardware will, I think, give the average gamer crashes on the order of once in an hour of gameplay.

 Using kernel-side drm modules compiled from the latest git makes Feisty's mesa work great. (i915 version 1.9.0). I played nexuiz for > 8 hours on it :) With Feisty's kernel drm modules, nexuiz sometimes made the video lock up, as above. So as I said, kernel drm modules are the only thing holding Feisty back from working fairly solidly out of the box on g965 hardware. (2D support is ok already).

 It might not be necessary to go all the way to 1.9.0. I've been compiling the latest drm and mesa on edgy for months now, with quite good results.

I have an Inspiron 1420N with Ubuntu 7.04 installed by Dell. When I launch certain OpenGL applications (e.g. the screensaver Euphoria) X locks up. X does not respond to ctrl-alt-backspace and I cannot switch virtual terminals. I do stay logged in over ssh. The last entry in /var/log/messages is "[ 2674.200000] [drm:i915_wait_irq] *ERROR* i915_wait_irq: EBUSY -- rec: 34 emitted: 62". That last number, 62, varies.

If X was started by GDM, gdm detects that it locked up and restarts it. However, X does not start and gdm sits forever trying to start it. Stopping gdm and trying startx as root gives the following messages:

> Peter, now that the 7.10 Gutsy Gibbon release of Ubuntu is out, we were wondering if you can still reproduce this issue.

 I haven't tried, since I'm still using the latest git mesa and drm (kernel and userspace).

 Next time I'm planning to reboot anyway, I'll try to remember to switch back to the shipped kernel drm modules, and all that.

Brian> fixed in Gutsy
 I don't think that thread sheds any light on this. g965 usually worked even in Feisty, but some GL apps triggered bugs.

Peter F> lockups with gm965
 If you haven't tried using the latest git drm and mesa, you might want to try. I'll attach a script I use to run git-pull, compile and install drm and mesa. Run it from a directory where you have a "drm" and a "mesa" directory, from doing a
git-clone something://whatever
You'll need kernel headers, e.g. linux-headers-[versionnumber]-generic
There's some good info on freedesktop.org about building things from git.

 I hope that's enough info to get you started.

> I checked out the git trees, ran you script (had to comment out the 64 bit mesa stuff)

 I'm glad you figured it out, since I created it for my own use and didn't take time to clean it up before posting it.

 Did your mesa get compiled with -fno-strict-aliasing? It needs that, maybe especially if you use a higher level of optimization than -O1. I'll attach a patch for configs/linux-dri-x86 (which again you'll have to clean up, because it changes lib_dir to lib32, for use on amd64 Ubuntu.)

> i915 identifies itself as 20070209 version, according to dmesg.

 good.

 Check your other mesa versions with
LIBGL_DEBUG=verbose MESA_VERBOSE=1 glxgears
(and/or glxinfo)

Leann> I'm flipping the status to Incomplete until we hear a report back from you regading stock Gutsy drm modules. Also marking Importance to "Medium".

 I have been unable to cause any lockups on Gutsy (kernel version sig Ubuntu 2.6.22-14.46-generic. I hadn't noticed that /proc file before :). I booted with just the Ubuntu version of the drm kernel modules, and ran stuff with LD_LIBRARY_PATH=/usr/lib LIBGL_DEBUG=verbose MESA_VERBOSE=1 nexuiz so I could verify that it was using /usr/lib/dri/i965_dri.so, not /usr/local/lib/dri. I checked with lsof that it's using the /usr/lib versions of all the libraries.

 Anyway, using stock Gutsy everything, I ran nexuiz and enabled all the eye candy (including HDR and dynamic lighting/shadows) at 1680x1050. timedemo demos/demo3 runs at < 3 fps, and sometimes down to 1 fps (on a g965, E6600, 4GB of DDR2-800). On edgy and feisty (with the previous version of Nexuiz, though), really low framerates would fairly consistently lock up my g965. I ran all five demos probably a couple times each.

 So I think it's fair to say that on desktop g965 hardware (Intel DG965WH motherboard), Gutsy no longer has problems. Or at least it's much better than Feisty. I'll try openarena, in case it reveals problems.

Leann> However against the linux-source-2.6.20 package this is being marked as "Won't Fix" as it does not meet the criteria for a stable release update.

 I agree. I think I replied to this bug on the 2.6.20 page without thinking. The Debian BTS just has bug numbers... Although they probably do something special for kernel bugs, because they use package names with the kernel version in it, too.

> libGL: OpenDriver: trying /usr/lib/dri/i965_dri.so

 Unless you replaced that file yourself, then your attempt to install mesa from git was not successful... You should be basically applying the changes I make to the 64bit config to your 32bit config, since you're running a 32bit system.

I get
peter@tesla:~$ LIBGL_DEBUG=verbose MESA_DEBUG=1 glxgears
libGL: XF86DRIGetClientDriverName: 1.8.0 i965 (screen 0)
libGL: OpenDriver: trying /usr/local/lib/dri/i965_dri.so
...

 because I changed the config file to make it look for the dri library in /usr/local/lib/dri.

 Good idea using Debian's packages. That's probably sufficient. It's surprising it doesn't work. I didn't know if there are any major differences between the g965 and the mobile gm965, but I would be surprised. OTOH I'm not trying ut2004.

  I'll try something that uses texture compression, since in the past I've found that always locked up. (even FXT1, not just DXTn with the external library).

 BTW, I played openarena for a couple hours this afternoon with no problems on my system (with Gutsy's mesa and drm). Of course, I'm using a g965, not an 855GM. I've found lockups are more common at lower frame rates, and openarena doesn't have enough eye candy to slow down a g965.

[Peter Cordes (peter-cordes)]

> this is a hard freeze :-(

 usually what happens is the X server exits, leaving the video hardware displaying whatever it was at the time. So the mouse doesn't move the cursor, and you can't ctrl+alt+f1 (because no X server is listening for that key combo.) However, it's only X that's affected. If you have another computer you can ssh in from, you can shut down cleanly. Or Alt+sysrq+r to take the keyboard out of "raw" mode, so e.g. ctrl+alt+delete should shut down cleanly. or hold alt+sysrq and hit s, then u, then b. (to sync, umount, and reboot.) The power button should also shut down cleanly.

 When X crashes like this, restarting it is no good. The video hardware is in some weird state and only re-POSTing will help, which only happens on a reboot or when coming back from a suspend/resume.

[Peter Frühberger (peter-fruehberger)]

oki - i try again, with the debian unstable packages and dri modules after a reboot.

[Peter Cordes (peter-cordes)]

> You could fetch the ut2004 demo

 The demo only has one level per game type, so I couldn't try the map you suggested... I was able to reproduce the lockups with ut2004 on my system. So although gutsy is much better than feisty or edgy were, it's still not perfect.

 I got lockups most quickly on the "bombing run" match type. It locked up within a minute on that, after ~half an hour of the assault. This was at 1024x768, dynamic lights disabled. Lockups seemed equally frequent with all three combinations I tried: gutsy kernel and userspace; gutsy kernel + git libdrm and mesa; git kernel drm + git libdrm and mesa.

 The error messages were always the same.

 Those messages don't look familiar, so I think they must have fixed one thing, and ut2004 is uncovering another problem.

 So gutsy still has problems, but so does the latest git kernel+userspace. :( So at this point backporting the kernel drm into the gutsy kernel won't help anything, AFAIK. This might be more of a mesa dri bug, not a drm bug.

 I'm having fun with ut2004 on my old s754 athlon64 + 7600gt, though. :)

  I'll report this on freedesktop.org.

[Leann Ogasawara (leannogasawara)]

Thanks for the updates Peter C. Per your comments it sounds like the bug this report was originaly about has been resolved. As a result I am going to mark this bug as 'Fix Released'. However it appears that you may have discovered other issues. Please feel free to open a new bug report regarding those issues.

Peter F, it seems you have slightly different hardware than what Peter C originally reported against. If your issue persists can you please open up a new report as well.

Please continue to use this report as a means of communication if it is helpful. Thanks again for your feedback and helping to make Ubuntu better. And please continue to file reports for any future bugs you encounter. Thanks!

[Peter Cordes (peter-cordes)]

This did turn out to look the same as the lockups I had seen before with SPECViewperf.

 See https://bugs.freedesktop.org/show_bug.cgi?id=7962, where I've mentioned this bug, and passed along the info about the ut2004 lockups.

[nbubis (nbubis)]

I seem to have the same problem with a fresh install of gutsy as well. running 3d apps (blender, k3d) locks up X. I'm running on a dell 1420n with a 965 GMA.
Is this really an error with the kernel modules? is there a solution \ workaround for this problem?

 AFAIK, gutsy is as stable as the latest git versions of libGL (and
/usr/lib/dri/i965_dri.so), libdrm, kernel-side drm.

 Also AFAIK, the fix for the graphics lockups could be in any of those
pieces of software.

  When I say "as stable", I don't mean perfectly stable. e.g. ut2004-demo
locks up my g965 quite easily. So does SPECviewperf 9.0.3's tcvis. It is
better than e.g. Edgy, where even some screensavers could lock it up.

keeps crashing on Hardy Heron (alpha1) as well!
this includes xorg7.3 and updated mesa and libdrm pckgs.

I find it hard to believe that so many people with this chip are incapable of running basic 3D software..
