[Nouveau] [Bug 35876] New: Hard GPU hang on nvidia
https://bugs.freedesktop.org/show_bug.cgi?id=35876 Summary: Hard GPU hang on nvidia Product: Mesa Version: git Platform: x86-64 (AMD64) OS/Version: Linux (All) Status: NEW Severity: major Priority: medium Component: Drivers/DRI/nouveau AssignedTo: nouveau at lists.freedesktop.org ReportedBy: maximlevitsky at gmail.com Created an attachment (id=45137) --> (https://bugs.freedesktop.org/attachment.cgi?id=45137) git snapshot Hardware: Geforce 8400M GS - (0x086700a2) Acer Aspire 5720G Userspace: Git tips of all components except Xserver.

Just 2D usage of compiz is enough. I will eventually test if even just 2D usage can trigger this.

https://bugs.freedesktop.org/show_bug.cgi?id=35876 --- Comment #1 from maximlevitsky at gmail.com 2011-04-01 19:49:11 PDT --- I might have being lucky with this bug, dunno. I looked at docomentation at envytools and it mentions that you can't do a tlb flush while pgraph is running on NV86. Well, thats known and code contains a workaround. What I did in addition to that is I took Martin Peres's code that suspends/resumes pgraph and hooked it into nv84_graph_tlb_flush. No hangs yet, but that doesn't mean anything yet. I added this code: nv50_graph_pause(dev); nv50_vm_flush_engine(dev, 0); nv50_graph_unpause(dev); So PGRAPH is paused when it is supposed to be idle. Yet, his nv50_graph_pause often complains that: [18931.100046] [drm] nouveau 0000:01:00.0: PGRAPH: PGRAPH paused while running a ctxprog, NV40_PGRAPH_CTXCTL_0310 = 0x11 [18937.770017] [drm] nouveau 0000:01:00.0: PGRAPH: wait for idle fail: 00000000 00000000 00000000 00000101! Let wait and see, but it could be that I am right and we need to pause PGRAPH more aggressively here. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.

I'm having the same problem with vanilla kernel v2.6.39-rc6. But there were no problems with v2.6.37 (may be I haven't tested it enough). I think, this should be fixed in the kernel (more exactly, in the "nouveau" kernel driver). -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.

Putting 'return FALSE' in can_exchange fixes the problem, last time I must have forgot to 'make install' or something. However, 'Option "PageFlip" "false"' doesn't help, because even if set, the condition in can_exchange lets flipping in some cases (if nouveau_exa_pixmap_is_onscreen() == FALSE). Not sure why that check is there. @Alexander Potashev - older kernel you describe just doesn't have pageflipping code, so sure you don't see it on it. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.

I switched my system to nvidia ctxprog, and Unegine tropics demo which used to hang after 3~5 minutes or runtime. Now it already runs for 40 minutes (and I will leave it for few hours) and compiz is on, I use the system, and I did s2ram cycle with tropics and compiz was on. No changes in mesa/other components were done, so its for sure the ctxprog.

I have finished the compare process.

(Well my card has 2 MPs, so that would make that 2 bits I guess :-) ) Attached patch was tested by 1/2 hour run of Unegine tropics game.

I'll say as often as it would take to justify making it automatic so I could run it in background and not play it as its not fun to play game too much, especially thi game that I don't like that much. In fact, I reproduced a hang with latest mesa, no reclocking and nvidia ctxprog. (Only thing that was on is power saving magic, but I had these crashes without it as well, so not likely to be the reason - still will test without it as well soon). -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.

I have another older dump of PFIFO that, where its not killed, and once again there is attempt to switch to channel #2 which is for DDX. In fact channel mapping (which just happens to be this way): Without compiz: 1 - framebuffer - idle (while in X of course) 2 - xserver EXA - occasional bursts while game runs. on screen panel updates (clock,etc..) mostly I think 3 - xserver AIGLX - not used at all, as I don't launch such clients 4 - game With compiz: 1 - framebuffer 2 - xserver EXA 3 - xserver AIGLX 4 - compiz - again, short bursts of activity time after time while game runs, probably to redraw windows that X clients (the same panel for example) writes to. 5 - game Also channel 0 seems not to be used at all, it with channel 127 are sort of special. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.

https://bugs.freedesktop.org/show_bug.cgi?id=35876 --- Comment #27 from maximlevitsky at gmail.com 2011-08-30 17:48:40 PDT --- Thanks to Marcin Ko?cielnicki, I understand now that hung PFIFO dumps were just a consequence of an attempt to execute 'software' command in the command stream. These commands indeed cause PFIFO errors, but that is normal as the error triggers an interrupt and kernel driver handles the error. In this case software command was used to signal a pageflip, and it was issued for every full screen 3d application. However I forgot to mention that I was running kernel nouveau driver with 'msi=1' option, an option that makes hardware use message signaled interrupts that are known to be broken on several systems because of chipsets bugs or else. Due to that in rare case, the interrupt was't delivered to kernel, causing PFIFO to hang waiting for software to service that interrupt. When I disabled the 'msi' option, which is disabled by default, the problem gone and I was able to test run supertuxkart for hour and 50 minutes, and I actually repeated that test few times with different variations, including running with nouveau's ctxprog and compiz. I am quite sure (knocks wood) that problem is gone. A side note is that I was getting hangs on one small webgl demo the http://helloracer.com/webgl/, and I was using older version of mesa because latest had rendering issues (resolved now and believed to be chromium bug actually). That demo generated a lot of PGRAPH errors (doesn't now) and once again since each error triggers an interrupt, eventually same hang would happen. Also running XV, syncs to VBlank and that also involves interrupts, and I had in past several hangs while using XV, so I won't be surprised if that was the cause (I used 'msi' option since it was introduced, and didn't expect this to happen) Thats all, and it seems (knocks wood again) that my card is finally stable. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.

I reproduced that once more without my patch of course. I got: [10459.780042] [drm] nouveau 0000:01:00.0: PGRAPH TLB flush idle timeout fail: 0x00c00603 0x0000014d 0x00005600 0x00000000 [10464.810946] [drm] nouveau 0000:01:00.0: PGRAPH TLB flush idle timeout fail: 0x00c00603 0x0000014d 0x00005600 0x00000000 [10469.826439] [drm] nouveau 0000:01:00.0: PGRAPH TLB flush idle timeout fail: 0x00c00603 0x0000014d 0x00005600 0x00000000 [10474.841967] [drm] nouveau 0000:01:00.0: PGRAPH TLB flush idle timeout fail: 0x00c00603 0x0000014d 0x00005600 0x00000000 [10479.770036] [drm] nouveau 0000:01:00.0: PGRAPH TLB flush idle timeout fail: 0x00c00603 0x0000014d 0x00005600 0x00000000 In kernel log.
