--- Comment #1 from [email protected] 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. _______________________________________________ Nouveau mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/nouveau
