Description Tomas Janousek 2009-11-20 10:55:09 UTC

When trying to play http://store.lisk.in/tmp/tile.ogv with mplayer with xvideo output (textured video) in dualhead, I get this:

[  258.177512] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung
[  258.177526] render error detected, EIR: 0x00000000
[  258.177530] i915: Waking up sleeping processes
[  258.177587] reboot required
[  258.177604] [drm:i915_wait_request] *ERROR* i915_wait_request returns -5 (awaiting 9359 at 9357)

[  258.178318] [drm:i915_gem_execbuffer] *ERROR* Execbuf while wedged
...

The dualhead configuration is this:
Screen 0: minimum 320 x 200, current 1680 x 1850, maximum 4096 x 4096
VGA1 connected 1680x1050+0+0 (normal left inverted right x axis y axis) 433mm x 271mm
   1680x1050      59.9*+
[...]
LVDS1 connected 1280x800+200+1050 (normal left inverted right x axis y axis) 331mm x 207mm
   1280x800       60.0*+
[...]
TV1 disconnected (normal left inverted right x axis y axis)

If only LVDS1 is connected, it plays fine. I remember playing that clip with no problem with 1920x1200 connected to VGA1, but I'm not 100 % sure -- I may try as soon as I get to that monitor again.

I can also confirm that mplayer -vo gl works fine, it's just xvideo.

I tried with the following kernels: v2.6.32-rc8-11-ga8a8a66, v2.6.32-rc5-81-g964fe08, v2.6.30-rc6-26-g0f6f49a, with and without KMS. I have xf86-video-intel 2.9.0, but I tried with 2.9.0-78-geda2bb2 as well. I can reproduce this in 100 % cases.

Neither dmesg nor Xorg.log show any errors or warnings regarding this, except those few lines, so I'm attaching my usual dmesg and Xorg.log just for details about my hardware.

I've tried playing video with Xv on 945GM, it will give me a black window with extended desktop. Didn't see GPU hang message here. My configuration is:
Kernel:       (drm-intel-next)5b8f0be0dce012d190a53d55240fe3fde6306476
Mesa:           (master)2b07b640619ac68344276ba0557ea46b2cbc3f26
Xserver:                (master)19f7c15e2008dab3c46ba3e14dfa353d01c74f72
Xf86_video_intel:               (master)eda2bb26783f7e9ef1ae659265930308378206e1

And it works well on 945GME(Aspire one)

The steps to reproduce this issue is:
1. xinit & (without VGA attached)
2. attach VGA
3. xrandr --output VGA1 --auto
4. xrandr --output VGA1 --right-of LVDS1
5. mplayer -vo xv mediafile

And FYI, following order can't reproduce the issue:
1. xinit & (with VGA attached)
2. xrandr --output VGA1 --right-of LVDS1
3. mplayer -vo xv mediafile

945GME(Aspire one) also has this issue with these steps

We just found that the video is offset up to the top of the desktop. only bottom line of video can be still seen from the desktop

Comment 8 Vasily Khoruzhick 2010-01-10 01:38:07 UTC

I can reproduce this bug on 2009Q4 software with 945GM hardware, but system doesn't hang, mplayer just shows video in a thin (1px) line at the top of the screen.

With composite enabled (kde effects with xrender backend) it shows video correctly in a window, but in fullscreen mode it shows only a black screen.

Comment 10 Chris Wilson 2010-06-05 07:10:05 UTC

Using XVideo on an extended desktop is fixed with:

commit d31abccd41c417338aac7c681e8bc6bd187b1843
Author: Chris Wilson <chris@chris-wilson.co.uk>

    i915: Support textured video on an extended desktop.
    
    Handle rendering textured video onto an extended desktop (>2048) by
    using a temporary pixmap. Note that we still cannot handle rendering to
    a greater than 2048 destination region, for that we will need to tile.
    Hmm, time to request a 2560x1600, 10bpc monitor...
