          Priority: medium
            Bug ID: 73785
          Assignee: dri-devel@lists.freedesktop.org
           Summary: Team Fortress 2 causes random GPU stalls on radeonsi
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: xamaniqinqu@gmail.com
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: git
         Component: Drivers/Gallium/radeonsi
           Product: Mesa

Created attachment 92376
  --> https://bugs.freedesktop.org/attachment.cgi?id=92376&action=edit
dmesg output related to the GPU stall.

Overview:
    The game "Team Fortress 2" causes the GPU to stall randomly. The stalls
sometimes resolve by themselves after ~1 min, but will occur again rapidly.

Steps to reproduce:
    1) Install "Team Fortress 2" through Steam (
http://store.steampowered.com/app/440/ ).
    2) Start the game, join a map.
    3) Play until the GPU hangs.
    4) Optionally: wait until GPU recovers.

Actual results:
    Frequent GPU stalls while playing Team Fortress 2. Sometimes video output
is restored after ~1 min.

Expected results:
    No stalls.

Build date and platform:
    Build date of all components: 01/18/2014
    Linux kernel version: 3.13-rc8 x86_64
    Mesa: git (566e0ddfd01dbadd75462fed5a3f141b9f494028)
    LLVM: 3.5-svn (commit 199570)

Additional information:
    I am running on a Radeon HD 7970 with DVI output at 2560x1440. Dynamic
power management is enabled. Disabling Hi-Z does not alleviate the problem. The
output of "dmesg 'drm\|radeon'" has been added as an attachment. I could not
reproduce the issue (yet) in another Source engine title, "Left 4 Dead 2".

Is this a regression?  If so when was the last time it was working?  Does
disabling dpm help?  Boot with radeon.dpm=0 on the kernel command line in grub.

Hello Alex,

Thanks for replying to my bug report.

I am not certain exactly when this bug was introduced or even which component
is involved, but since TF2 was stable a month ago it must be a regression.

I can report that having played well over 2 h with dynamic power management
disabled, that this bug is related to dpm.

However, playing with radeon.dpm=1 and setting
/sys/class/drm/card0/device/power_dpm_state to 'balanced' (down from
'performance'), the stalls become much less frequent, more in the range of once
or twice every 2-3 hours.

I think it's coincidence.  balanced and performance are the same on your chip.

I have the same Problem but it doesn't matter if DPM is enabled or not.

I can reproduce this Bug when i play on the map "Ghost Town"(Wave 666).
Always when the Tanks are comming and I going to them the GPU hangs.
On other maps its more or less random.

Every component was build yesterday
   Linux 3.14-rc1(drm-fixes branch)
   LLVM 3.5-svn
   Mesa 10.2-devel git
   xorg 1.15.0
   glamor 0.6

Yeah it helps

With R600_DEBUG=nohyperz there were no hangs in TF2 or Rust(both had the same
Problem)

I saw HyperZ in now disabled by default so R600_DEBUG is not longer needed.

which means it's not a HyperZ issue. It must be something else. Closing as this
bug report is against HyperZ.
