          Priority: medium
            Bug ID: 60969
          Assignee: dri-devel@lists.freedesktop.org
           Summary: [r600g] Lockup while playing OpenGL games with HD6450
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: rankincj@googlemail.com
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: git
         Component: Drivers/Gallium/r600
           Product: Mesa

HD6450 (CAICOS), kernel 3.7.7-201.fc18.x86_64

The PC quickly locks up while playing either WoW or Minecraft 1.4.7 with Mesa
from git. However, I have an earlier version of Mesa-git that plays both games
correctly. The mouse cursor continues to move after the freeze, but the
keyboard no longer responds.

The HEAD for my working Mesa is:

commit 0e2f26d5ea26febd16173aa8bbf7427b090e320f
Author: Ian Romanick <ian.d.romanick@intel.com>
Date:   Fri Feb 8 18:03:33 2013 -0800

    intel: Do not expose OES_compressed_ETC1_RGB8_texture or
ARB_texture_rgb10_a

    Older hardware cannot do ARB_texture_rgb10_a2ui, and the translation
    code for OES_compressed_ETC1_RGB8_texture was never implemented in the
    i915 driver.

I will try and bisect this issue when I have more time with the affected PC.
Note that this issue does not happen with either my HD4670 or HD4890.

According to git bisect:

974b482acaf62ced1e8981761a8bda252bd51fe1 is the first bad commit
commit 974b482acaf62ced1e8981761a8bda252bd51fe1

    r600g: fix lockup when hyperz & alpha test are enabled together. v3

    Seems that alpha test being enabled confuse the GPU on the order in
    which it should perform the Z testing. So force the order programmed
    throught db shader control.

    v2: Only force z order when alpha test is enabled
    v3: Update db shader when binding new dsa + spelling fix

    Signed-off-by: Jerome Glisse <jglisse@redhat.com>
    Reviewed-by: Marek Olšák <maraeo@gmail.com>

This results in GPU stalls, which can be reset succesfully.

Yes thanks, that patch seems to have worked. No lock-ups yet.
