Bug 73625

I am sorry, disabling ColorTiling2D does not fix it, but it definitely makes situation better. I suppose there are different bugs mixed here,  and disabling ColorTiling2D hide some of them.

mesa-9.2.5 (kernel-3.13-rc7) seems to work (at least with mpv), so it looks like regression in mesa.

Can you bisect?

Will try, but this machine is so slow

> Will try, but this machine is so slow

Can you be more specific what you did, which movie you looked?
I have the same gfx card and  Mesa git, so maybe I can help.

Did severall tests for Christian and Alex with UVD.

Only this "Sometimes there are visible screen corruptions (color squares)...) makes me wonder. Do you get it during UVD playback or later (xdm/kdm) logout?

I see it sometimes since later 3.13-rcX versions and Mesa git during KDM (glamor-0.5.1-39.14) logout. I'll try to get a picture (with photo camera) and retest with 3.12.7 and Mesa 10.0.2. Maybe it arise only after UVD playback.

For example this movie most of time triger instability

I do nothing special: player in full-screen mode, mouse in idle.

It is about UVD playback. I does not see any desktop corruption without GPU hanging. If it hangs, reboot are required in most cases, as image does not restored properly after gpu reset and restarting of Xorg does not help.

"looping" and  corruptions exist and with mesa-9.2.5, but seems that finely found trick:
sleep 1; xset dpms force off
before first use vdpay allow eliminate this.

Nice BD snipping...;-)

> I do nothing special: player in full-screen mode, mouse in idle.

Tried (all) combinations.
big window (start up)
switch to full-screen
switch back
change window to smaller KDE 4.12.1 default size
switch to full-screen
switch back...

I even can 'scroll' with the mouse wheel forth and back

=> NO blocks (squares).

Linux 3.13.0-rc7
Mesa git and 10.0.2 (openSUSE 12.3)
X.org 1.15 (openSUSE 12.3, Xorg repo)
xf86-video-ati-7.2.0 (latest openSUSE 12.3, Xorg repo)

But I found something with your test.mkv and another .mkv file.

It seems to be that we have a start up/initialization problem with UVD (2.2, here). When your test.mkv file is the first one after start up/login it takes several seconds to start and I had one hang. Whole system was not dead but X.  Sadly no log.

After running other files with UVD *.mkv (big files?) start up is somewhat better. But slower then others (e.g. Serenity - HD DVD Trailer.mp4).

But NO squares/blocks at all.

Some redraw stuttering during switch from full-screen to (small) window and fewer back to full-screen. Much WORSE with Glamor. Generally speaking UVD takes much more cycles under Glamor.

Glamor (a bug/leak; glamor-0.5.1-39.14) is the culprit for my reported color squares during logout from KDE 4.12.1. If system starts without Glamor (the X server 1.15.0 thing, https://bugs.freedesktop.org/show_bug.cgi?id=70706 ;-) I get NOT any such things during fade out/logout from KDE.

Last thing:

Sometimes UVD starts reliable with sound (I even can scroll with the mouse wheel forth and back) but with empty black video window (only the white mplayer scale during scroll).
Worst case was:
1 normal start
then 5 BAD
then OK, again...

Now I get partially some color squares:

Glamor (glamor-0.5.1-39.14)
KDE 4.12.1
kwin
GL desktop effects ON
UVD/video window on all virtual desktops (sticky)

scroll with mouse wheel through all (4 virtual desktops) GL cube

Sometimes some redraws show partially color squares, as long as I gave the system time for full refresh...

=> system is on its limits?! 

Or glamor is in the way or need optimization.

I think there are two kinds of problems here:
first: looping, corruption, black window (also have this).
and seems there are 'sleep 1; xset dpms force off' in terminal  before using vdpau workaround for that.
second: gpu hangs, which seems to be a mesa regression after 9.2.5

Did you try to set dpms off after boot before seeing that?

I suggest you put the dpms off into your X startup script and then try to bisect the GPU lockup first.

I try to do that, but seems my testing was not enough in some case as R600_DEBUG=nosb helps.

My classification of problems was wrong, while bisecting from step to step was looping or gpu hanging. It seems that problems exists more early (it is why commit 29ff2e907d6c54f95be6dfa72201fd25bbd50fcd was marked as bad), but with sb it mach easy to reproduce. Enabling sb with mesa-9.2.5 makes it behavior with uvd similar to current current git (looping almost immediately, but not sure about gpu hangups).

It seems to me that uvd is stable with R600_DEBUG=nosb and current mesa (it is only necessary workaround). I mean stable behaviour - if it able to play some movie it always play it, or if it hang gpu on other it always hang it there.

There are some low resolution (1024x560, 1024x600) h264 movies that with R600_DEBUG=nosb hang GPU, but strange thing - uvd work with R600_DEBUG=sb with it!

It is seems a different issue and this:

helps here (it works with R600_DEBUG=nosb), thanks.
