Nouveau - Feb 2010 - [Bug 26733] New: Full-screen XV causes graphics lockup

http://bugs.freedesktop.org/show_bug.cgi?id=26733

           Summary: Full-screen XV causes graphics lockup
           Product: xorg
           Version: git
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
        AssignedTo: nouveau at lists.freedesktop.org
        ReportedBy: tavianator at gmail.com
         QAContact: xorg-team at lists.x.org


Since updating libdrm, xf86-video-nouveau, and the DRM module to the latest GIT
(as of today), any time I make a video full-screen in VLC (with XVideo output)
on my nv92, the screen freezes.  Through ssh I found this in dmesg at the time
of the crash, which I'm told is bad:

A drm module I compiled on the 21st works fine, so it looks to me like this
commit caused it: 966a2b2e31b4d7fd72733ebb78a74bf0054a3f85.  And sadly that
commit fixes suspend for me, so I either get working full-screen XV or working
suspend.

Never mind, a proper bisect points out 21c684bc635f76c71741541eb10dfa86fd846cfa
(drm/nv50: switch to indirect push buffer controls) as the offending commit.

okias is right, but now it's happening during normal use too.  It seems to
happen especially often while flash is playing something.  It's getting a
bit
annoying, so I'd be glad to test any patches you can suggest, or anything
else.

I agree. Day ago my Nouveau hang too without Xv (maybe was flash running, not
sure).

I accidentally turn on Kwin OpenGL effects. So, maybe problem still occurs, but
I wasn't able reproduced it again (tested 20 minutes of Xv video).

Well it's still happening for me, once even without X running at all.

Look like it's fixed by "drm/nouveau: fix a nouveau_bo dereference
after it's
been destroyed", can you test it?

NACK on that, just got another PFIFO_DMA_PUSHER lockup, during normal use this

Can you update to this kernel, it's the only *known* issue which could cause
something like this to occur:

If one of us nouveau devs could reproduce this issue, we'd have a way to
find
out *why* it's happening and fix it.  Unfortunately, I don't think any
of us
can, so it's hard to fix.

I've had more than a few xvideo related lockups over time, but this time i
was
able to see it was preceded by a PFIFO_DMA_PUSHER. Don't have any concrete
ideas yet, besides carefully reviewing the xvideo code in the ddx. You are
welcome to share any ideas or thoughts that might help solve this.

Had a look at the nv50 xv code, found some odd things. No sure if they are the
cause, but it doesn't hurt to fix things. You are ofcourse welcome to try
the
latest ddx (that's the xorg driver for those who don't know).

Hi, same or similar problem here, often during day to day work under kde4.4
with NVIDIA Quadro NVS 140M.

I will try out "as of today" DDX as soon as possible and report back
(unless
I'm told that this is a completely different bug...)

I noticed something strange.
I've been experiencing this issue for a long time now, and I'm almost
sure : it
happens when my computer is hot.

I have a very bad ventilated laptop (Compaq Presario CQ60). Sometimes it even
suddenly shutdowns because of his temperature.

When my laptop is up from the morning and I try to play a video on the evening,
that causes graphics lockup (let's say in 90% of time, even more if it's
a HQ
video). His temperature is then around 90?C.
However, if I let my laptop cool down, then turn it on (most often his
temperture will then be 65?C) and try again, there's no problem.


That seems weird, and maybe I'm wrong. But that could explain why the issue
happens only to some people, and why it doesn't always happen.

I upgraded last month to the latest git revision. That seems even worse : I now
occasionally get graphics lockup even when I don't play videos. And I
can't
watch a HD video for more than... let's say twenty minutes.

Does this still happen with the latest kernel/xf86-video-nouveau?

That laptop isn't my primary computer anymore so I'll have to update it
and
check.  I'll let you know in the next couple days.  Last time I used it
(last
year) it still locked up every once in a while but I'm not sure if that was
directly related to this bug.
