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

What was the problem? Were you able to narrow it down at least?

--- Comment #2 from Vedran Miletić vedran@miletic.net --- Last week I rechecked, but all I got on master was non-working mouse clicks (weird, I know) under Wayland and crashes under Xorg. I'll recheck again.

Using rawhide especially so early into a release you should expect issues all over the place. This isn't a very good way to be testing Mesa from git and reporting issues, for example there can be kernel/gcc/x/desktop bugs etc it makes it hard to narrow things down, on top of that package versions are constantly changing. It's better to Upgrade Mesa/LLVM/kernel etc on a stable distro for your testing.
After rebo a reboot, however, with Mesa git running both the desktop and games, performance in games is very bad, rougly 1 fps.
It could be anything but possibly you have fallen back to software rendering.
Anyway Fedora 28 will be using LLVM 6.0, Linux 4.16. I'm going to close the bug report as there isn't much to go on here, but feel free to reopen if you still have issue with the stable Fedora 28 release.
