            Bug ID: 88968
           Summary: Unit mouseover in World of Warcraft (wine, D3D)
                    freezes up the entire system
           Product: Mesa
           Version: git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/radeonsi
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: rubykuby@gmail.com
        QA Contact: dri-devel@lists.freedesktop.org

I'm not sure if I selected all the right bug tracker things, or whether this is
a Mesa or X11 bug.

I have an AMD Radeon HD 7950, which is practically identical to the R9 280.
When running World of Warcraft in wine, everything works fine until I mouseover
a unit. This mouseover should trigger a glow effect around the unit, but
instead freezes up the entire system, forcing me to reboot.

This bug does not occur in standard Ubuntu 14.10. It does occur in Ubuntu 14.10
with the oibaf/graphics-drivers PPA added. It also occurs in Manjaro 0.9.

Ubuntu 14.10 versions:
libgl1-mesa-glx - 10.3.0-0ubuntu3
xserver-xorg-video-ati - 1:7.4.0-2ubuntu2

Oibaf versions:
mesa - 10.5~git1502040730.6fd4a6~gd~u 
xserver-xorg-video-ati - 1:7.5.99+git1501140731.c80ea1~gd~u

Manjaro 0.9 versions:
mesa - 10.4.3-1
xf86-video-ati - 1:7.5.0-1

This bug does not occur when turning on the OpenGL mode within WoW. This bug
does not occur in the Catalyst drivers.

I do not know how to gather debug information, but I'd be glad to provide them
if given instructions.

So it seems like it's a regression between Mesa 10.3 and 10.4. Any chance you
could bisect between those?

I'm going to need to know how to "bisect".

A web search for "git bisect howto" should get you started.

Nailed down the bug to commit 1f6c0b55df9f3553b18062ad2c7e2dc021d4c731:

    radeonsi: set number of userdata SGPRs of GS copy shader to 4

    It only needs the constant buffer with clip planes and read-write resources
    for the GS->VS ring and streamout. That's 2 pointers.

    Reviewed-by: Michel Dänzer <michel.daenzer@amd.com>

The commit before that commit (68d36c0bb532987db27a596408e0326f20ca0365) does
not crash and burn.

Used the following configure command for each build:

./autogen.sh --prefix=/usr/local \
               --sysconfdir=/etc \
               --with-dri-driverdir=/usr/lib/xorg/modules/dri \
               --with-gallium-drivers=r300,r600,radeonsi,nouveau,svga,swrast \
               --with-dri-drivers=i915,i965,r200,radeon,nouveau,swrast \
               --with-egl-platforms=x11,drm,wayland \

               --enable-nine \
               --enable-opencl \
               --enable-opencl-icd \
               --with-clang-libdir=/usr/lib

Followed by make and make install.

Running on Arch Linux currently, with the following package versions:

xorg-server - 1.16.4-1
xf86-video-ati - 1:7.5.0-1
linux - 3.18.6-1

This bug is no longer reproducible on my system. Two variables have changed:

I'm now running Mesa 10.4.6 (small point update) & WoW has had an update to
version 6.1.
