messages.log part

Each time I try to start openarena or any other game, card locks up (not in
menu, but in game).

I'm not sure, but log in messages seems to be related to this issue (see
messages attachment).

Software versions:
kernel 2.6.37.2
libdrm 2.4.23
mesa 7.10.1
xf86-video-nouveau 0.0.16_git20101217

While nvfx (3d gallium driver) isn't supported, i run few tests with
nouveau-git (commit 72690683e35680d912e9b8ff2ee0b7a18631dd0d - "drm/nouveau/pm:
Document and expose CL and WR for 0x1002Cx") and mesa-7.12-devel (OpenGL
version string: 2.1 Mesa 7.12-devel (git-a09b7f7)).

Other software - Q3 Arena linux demo.

Results kinda strange.

Default settings
Timedemo 1 
demo demo002 - lock up card very fast, can power off machine via ACPI.
demo demo001 - works!

geometry detail set to low
demo demo001 - not tested
demo demo002 - works!

geometry detail set to medium
demo demo002 - lock up after some time (not at start of level)

For perflvl=0 

even demo001 lock up after some time in the middle (always at same place).

So, I guess we run ahead or behind GPU, mostly in sending geometry data? need
more test with perf mesa demos, for example ....

currently my performance levels are

drm] nouveau 0000:01:00.0: mem timing table length unknown: 14
[drm] nouveau 0000:01:00.0: 2 available performance level(s)
[drm] nouveau 0000:01:00.0: 0: core 300MHz memory 1000MHz voltage 1300mV
fanspeed 100%
[drm] nouveau 0000:01:00.0: 1: core 500MHz memory 1000MHz voltage 1400mV
fanspeed 100%
[drm] nouveau 0000:01:00.0: c: core 100MHz memory 501MHz voltage 1300mV
[TTM] Zone  kernel: Available graphics memory: 255992 kiB.


and perflvl 1 lock up whole machine pretty fast (before i managed to run any
bench, even  with just composited, via Xrender/Kde 3.5.10 desktop)

Guess I need additional "bug" for tracking this. And probably one more for
tracking invisible VTs after s3 sleep ....

OK, perf/vertexrate lockup card.

If I disable (in vertexrate.c) everything, but immediate mode, i have

guest@slax:~/botva/src/demos/src/perf$ ./vertexrate
Vertex rate (10000 x Vertex4f)
  Immediate mode: 11.2 million verts/sec

perf/vbo works, but as far as I can see it doesn't draw anything  visible.

Ok, VBO glDrawArrays works too:

guest@slax:~/botva/src/demos/src/perf$ ./vertexrate
Vertex rate (10000 x Vertex4f)
  Immediate mode: 11.5 million verts/sec
  VBO glDrawArrays: 12.8 million verts/sec
guest@slax:~/botva/src/demos/src/perf$                      

Uncommenting anything else lock up card.

Sorry, in my case aux. power was NOT connected to card. Now fastest perflevel
works for Q3/demo001 (up to 78.0 fps for 1280x1024x32@60, but GPU temp raised
to 92 C). 

But unmodified vertexrate demo still freezes card even with default boot clocks

Try cutting the vertexrate demo down to a minimal subset that causes the lockup
and trace the command buffer.
You're getting DMA_VTX_PROTECTION so you're likely accessing out of bounds
vertex data somehow.
If you can find the commands that cause it and compare with the gallium code
you might be able to find the error.

Attached patch for tracing command buffer (apply to libdrm).

More info.

When I set NVFX_SWTNL=1 ./vertexrate it also works without lockup. I was
playing with amount of vertex data, and found what  defining MAX_VERTS up to
1263 works OK, but 1264 and up   lead to card lock-up.

So, i traced two cases, and diff'ed first full trace (with lockup) and part of
second trace (33 Mb big, due to successful execution of test).

So, I bisected mesa tree (7.11 branch)

Result:

2a904fd6a0cb80eec6dec2bae07fd8778b04caf3 is the first bad commit
commit 2a904fd6a0cb80eec6dec2bae07fd8778b04caf3
Author: Marek OlЕЎГЎk <maraeo@gmail.com>
Date:   Sun Dec 26 04:30:51 2010 +0100

    st/mesa: set vertex arrays state only when necessary

    The vertex arrays state should be set only when (_NEW_ARRAY | _NEW_PROGRAM)
    is dirty. This assumes user buffer content is mutable, which will be
    sorted out in the next commit. The following usage case should be much
faster
    now:

    for (i = 0; i < 1000; i++) {
       glDrawElements(...);
    }

    Or even:

    for (i = 0; i < 1000; i++) {
       glSomeStateChangeOtherThanArraysOrProgram(...);
       glDrawElements(...);
    }

    The performance increase from this may be significant in some apps and
    negligible in others. It is especially noticable in the Torcs game (r300g):
        Before: 15.4 fps
        After: 20 fps

    Also less looping over attribs in st_draw_vbo yields slight speed-up
    in apps with lots of glDraw* calls.

I guess the bisection failed in this case, because that commit contains a bug
that was fixed later.

gallium: notify drivers about possible changes in user buffer contents ? It was
well-masked for Q3 arena until extension sorting exposed it there, but I run my
./vertexrate (reduced) test, and you can see whole bisect log... May be nvfx
played too much with mesa/gallium internals.

Created attachment 53562
  --> https://bugs.freedesktop.org/attachment.cgi?id=53562
hand-typed "log"

While trying some self-made liveCD based on slackware-current, I found
Slackware's Mesa works fine for both Celestia, and Q3 timedemo demo002.
Slackware currently uses Mesa 7.10.2/libdrm 2.4.24/ and some nouveau DDX from
march, 2011. I've compiled 7.11 branch , and discovered it hang videocard like
7.12 does on my main system. Then I just set good commit at last one from Luca.
And even if i keep all other components the same
(libdrm-2.4.27/xf86-video-nouveau few comments behind git/kernel 3.2.0-rc1
mainline) freeze go on and off with just mesa versions.My bisect compilation
was without any llvm stuff (normal compilation has llvm 2.9). nice mistery, and
thanfully  whole machine not locked up hard, only videocard, it seems.

[Bug 34969] [nouveau] Card lockup on openarena

[bugzilla-daemon]

https://bugs.freedesktop.org/show_bug.cgi?id=34969

--- Comment #20 from Andrew Randrianasulu <randrik@mail.ru> 2012-04-14 14:53:55 PDT ---
At least my hangs seems  to be  fixed by big driver rewrite. Currently using
3.4.0-rc2 nouveau kernel, libdrm up to commit
292da616fe1f936ca78a3fa8e1b1b19883e343b6 ("nouveau: pull in major libdrm
rewrite"), mesa master up to commit b2df031a959f36743527b9abc89913ce4f895de3
("r300/compiler: Fix nested flow control in r500 vertex shaders") and
xf86-video-nouveau up to commit fb3a36b1e5af0f81bb266da894d3442eed8e4e55
("nve0: initial exa/xv acceleration for kepler chipsets").

Please, re-test with new code.

Moving to Nouveau.

Are you still experiencing this issue with an updated graphic stack, aka.
kernel 3.18, mesa 10.4, libdrm 2.4.58 and f86-video-nouveau 1.0.11?
