          Priority: medium
            Bug ID: 65192
          Assignee: dri-devel@lists.freedesktop.org
           Summary: Screensavers lock up machine (screen goes blank,
                    keyboard unresponsive, sound loops; sysrq/ssh
                    possible)
          Severity: major
    Classification: Unclassified
                OS: Linux (All)
          Reporter: luziphermcleod@yahoo.ie
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: git
         Component: Drivers/Gallium/r600
           Product: Mesa

For a while now, some screensavers sometimes lock up my machine. That means all
screens go blank, the keyboard is unresponsive (numpad-key doesn't toggle the
indicator led), the sound loops. But I still can use ssh from a remote machine
and the magic-sysrq-keys also work.

There is nothing to see in neither /var/log/messages (acquired via netconsole)
nor /var/log/Xorg.0.log.

I can trigger the bug (or regression, I think it used to work about 2 months
ago) reliably by using the Xfce4 screensaver settings application, which has a
preview of the screensaver selected. When switching between screensavers, the
lockup quickly occurs. A good candidate is the screensaver named "AntMaze", it
alsmost always locks up my machine (only worked once so far).
Other stuff works quite solid, Half-Life 2 worked multiple hours today.

Setting R600_HYPERZ=0 in /etc/environment didn't help. Also occurs on kernel
3.8.0-rc7.

I'm happy to provide more info if needed.

Are you sure this ended up in the environment of the screensaver hacks? Can you
try e.g.

R600_HYPERZ=0 /usr/lib/xscreensaver/antmaze

manually to see if that works better? Same thing might be interesting for
R600_DEBUG=sb (or R600_LLVM=0, but AFAICT you're building without the r600g
LLVM compiler backend anyway?).

I did as suggested and ran:

R600_HYPERZ=0 /usr/lib/misc/xscreensaver/antmaze

This worked more often, but I could make it crash when using different
screensavers. Using

R600_HYPERZ=0 /usr/bin/xscreensaver-demo

and switching between screensavers crashed as often as without R600_HYPERZ=0.
Also, the screensaver juggler3d crashed twice when exiting the window it ran
in.

R600_DEBUG=sb didn't help either.

I also confirmed that environment variables are working as they should via
setting GALLIUM_HUD.

Beware that AFAIK the screensaver hacks aren't spawned from the
xscreensaver-demo process but from the xscreensaver daemon process. Did you
confirm that the latter saw the environment variable?

I'm very sure that the environment variable is seen. Today, I added it to my
/etc/environment again, restarted, and confirmed it is there by echo
$R600_HYPERZ, which printed 0, as expected.
I'm starting X manually (with startx), so I'm quite certain that the
xscreensaver daemon process also sees the variable.

All the following tests have been done with R600_HYPERZ=0 in /etc/environment.

As I mentioned in my previous comment, starting antmaze with the command
R600_HYPERZ=0 /usr/lib/misc/xscreensaver/antmaze
works more often. In fact I couldn't get it to crash in about 25 tries today.

What did crash was again juggler3d on the third try when _closing_ its window.
The command used was:
R600_HYPERZ=0 /usr/lib/misc/xscreensaver/juggler3d

Also, by using the xscreensaver-demo application (with R600_HYPERZ=0 in
/etc/environment) and switching between random screensavers, I could trigger a
crash quickly.

More info:
I tried again with juggler3d and it crashed first time upon exit. flurry also
triggered the crash on exit.
So I now suspect that antmaze isn't problematic - it is not starting a
screensaver that causes the crash, but closing one. As I switched screensavers
randomly in xscreensaver-demo, I just by chance clicked on antmaze when I had a
problematic screensaver selected previously.

Can you try confirming that, e.g. by trying Mesa from the 9.1 branch or an
older snapshot from master?

--- Comment #9 from Luzipher <luziphermcleod@yahoo.ie> ---
Unfortunately I couldn't confirm my thoughts. But I still am quite sure I did
not have those problems earlier - I had screensavers and youtube last year and
didn't notice regular crashes. I frequently use this linux installation, in
fact it's my main os for several years now, so I really would have noticed.
Maybe it's another package ? X, libdrm, radeon-ucode, xf86-video-ati come to
mind. Maybe mostly radeon-ucode, as I have the feeling that the problems
started at about the same time as the buzz on the uvd code drop.

Well, tests done (I could reproduce the crash on every of these with directly
started juggler3d on closing the window, mostly first or second try):

mesa-9.0.3 (forgot to get glxinfo)

mesa-9.0.1.ebuild, glxinfo:
OpenGL renderer string: Gallium 0.4 on AMD RV770
OpenGL version string: 3.0 Mesa 9.0.1
OpenGL shading language version string: 1.30

mesa-8.0.4-r1.ebuild, glxinfo:
OpenGL renderer string: Gallium 0.4 on AMD RV770
OpenGL version string: 2.1 Mesa 8.0.4
OpenGL shading language version string: 1.20
with 8.0.4, I got only garbage and a lot of these messages:
radeon: The kernel rejected CS, see dmesg for more information.
dmesg:
[ 1580.805418] radeon 0000:02:00.0: r600_cs_track_validate_cb invalid tiling 6
for 0 (0x08110668)
[ 1580.805463] radeon 0000:02:00.0: r600_packet3_check:1720 invalid cmd stream
573
[ 1580.805465] [drm:radeon_cs_ib_chunk] *ERROR* Invalid command stream !



I also tried the oldest kernel I have with 8.0.4, it's a vanilla 3.4.0-rc6.
Even there I could get the same crash after closing the window with the garbage
output.

I think this bug is fixed.

I retested for this issue on current mesa git (commit    
7568a89500c35f14cbd397f87c77acc915afc672) on kernel 3.10.0-rc7. I could start
and exit juggler3d at least 20 times without crash as well as use the
xscreensaver-demo application for switching between screensaver previews.

Sorry for not being able to nail down the issue better, but I have limited
time.
