            Bug ID: 103917
           Summary: [gfx9/Vega] Performance regression in master, 17.3
                    works fine
           Product: Mesa
           Version: git
          Hardware: All
                OS: All
            Status: NEW
          Severity: critical
          Priority: medium
         Component: Drivers/Gallium/radeonsi
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: vedran@miletic.net
        QA Contact: dri-devel@lists.freedesktop.org

I'm using Fedora rawhide (to become 28) along with Mesa 17.3.0-rc3, LLVM 5.0.0
and Kernel 4.15-git. If I install Mesa 17.3.0-rc5, everything still works fine.
If I install Mesa git, everything works fine with 17.3-rc3 running desktop and
17.4 running games.

After rebo a reboot, however, with Mesa git running both the desktop and games,
performance in games is very bad, rougly 1 fps.

I tried to bisect, but wasn't able to figure out what commit exactly is causing
the problem. I compile Mesa with

./autogen.sh --enable-egl --enable-driglx-direct --disable-gles1 --enable-gles2
--enable-shared-glapi --enable-glx-tls --enable-dri --enable-texture-float
--with-dri-drivers="" --with-egl-platforms=drm,wayland,surfaceless,x11
--with-gallium-drivers=r600,radeonsi,swrast --with-vulkan-drivers=radeon
--enable-opencl --enable-opencl-icd PKG_CONFIG_PATH=/usr/local/lib64/pkgconfig
--enable-nine --enable-gbm --enable-va --enable-vdpau
--libdir=/usr/local/lib64; make clean; make -j4; make -j4 check
