            Bug ID: 95282
           Summary: system hang on video playback via vdpau
           Product: xorg
           Version: git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: critical
          Priority: medium
         Component: Driver/nouveau
          Assignee: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
          Reporter: estellnb-7Km2I/eHSAQdnm+yROfE0A@public.gmane.org
        QA Contact: xorg-team-go0+a7rfsptAfugRpC6u6w@public.gmane.org

Yesterday I have installed the proprietary firmware for nouveau as described
under wiki/VideoAcceleration/#firmware and now my machine hangs reliably on
start of video playback. If vdpau is not used (i.e. by specifying xine -V XShm
xy.mkv) then it does not hang. It first starts to hang, then there is a short
moment where it reacts on pressing num lock and where playback continues and
then it hangs forever.
  When switching to vt02 before playback starts you can see several messages;
it also reacts on Alt-PrnScr-l/m/p printing out that it would now print the
memory/registers/backtraces but then does not actually print them unless you
presss Alt-PrnScr-C. There appears to be nothing in the log (switched to vt02
is the last message in the xorg.0.log).

Interesting. Looks like we messed up and somehow the a rendertarget was not
mapped into vram, and then the bsp/vp engines hung (and I never figured out how
to reset them).

Does xine use GL + VDPAU in separate threads? If so, that could definitely be
the cause. I know kodi does that, and I think mpv does as well. mplayer is what
I developed VP2 support with, and was pretty reliable.

much better with 4.6.0-ARCH-00466-ge80ac9b. However sometimes I still get a
hang; I will have to assert whether the occasional hangs do really stem from
vidoe playback ...

System/kernel hangs still occur in 20-30% of the time but only when xine
intializes playback. Once it has successfully started to play it will continue
until it finishes (4.6.0-ARCH-00466-ge80ac9b). The bug still depends on vdpau
since there are no hangs when starting xine with -V XShm.

  Worse than ever with 4.7.0-rc1-ARCH-11985-gf758c64. Now xine has crashed 3
out of 3 times on startup using vdpau for video playback. Last known better was
4.6.0-ARCH-00466-ge80ac9b.

  Same problem with 4.7.0-ARCH-13902-gd491e80. Immediate crash on starting xine
video playback when started with vdpau; the only escape is via SysRQ-keys.
Anyone here who would care?

dmesg while trying to play with vdpau by xine

 There is not much in the logs except:
nouveau 0000:01:00.0: bsp: Watchdog interrupt, engine hung.

 tested with kernel 9ca581b50dab6103183396852cc08e440fcda18e and a freshly
downloaded firmware.

  What may I do in order to get more meaningful debug information? Is vdpau
playback an issue that is being worked upon?

The same with VLC-2.2.4 (DVB-T stream), VDPAU, kernel 4.9.4, mesa-13.0.3,
xf86-video-nouveau-1.0.13. Any web browser crashes KDE Plasma - XOrg-server the
same way - it does not react to anything or it také ages to react. Mpv
absolutely stable till now using opengl-hq profile.

[Bug 95282] G96: system hang on video playback via vdpau

VDPAU - playback still crashing / not implemented with 4.10.0-rc8+ (Wed Feb 15
13:10:17 CET 2017) for the NV50 family (tested with G96GLM [Quadro FX 770M]. As
vdpau support for this card is on your ToDo-list at
nouveau.freedesktop.org/wiki/VideoAcceleration at least for the iso6avc1mp41
and the H.264 codecs I have tested videos with these codecs  and both videos
have crashed with xine -V vdpau right after xine started having done some
init-steps first. I will add a screenshot of these messages shortly.

screenshot trying to play an iso6avc1mp41 file - hanging on startup

You can see some messages including the message that avc1 has not yet been
implemented. Still I wonder why it is crashing if it can not use VDPAU directly
for video decodation. Though I have run nice -20 dmesg --follow in another
terminal at the same time no messages have appeared while xine was hanging the
system. Quite a while after startup the music (and only the music) played for
short but that was all of what had happened after the given messages appeared
on the xine-console. Escaping with SysRq-S-U-B was still possible.

  Anyone here who could asses whether the hang-problem with vdpau could be
related to GART/IOMMU? Here is what I have in my dmesg:

(In reply to poma from comment #9)

I confirm – starting xine is enough without any need of playing video. I get
the same error as in comment #9 Still the error looks a bit different than one
in the log from comment #3
