            Bug ID: 101198
           Summary: Major performance regression for AMD card
           Product: Mesa
           Version: git
          Hardware: x86-64 (AMD64)
                OS: All
            Status: NEW
          Severity: major
          Priority: medium
         Component: Drivers/Gallium/radeonsi
          Assignee: dri-devel at lists.freedesktop.org
          Reporter: dark.shadow4 at web.de
        QA Contact: dri-devel at lists.freedesktop.org

With the latest git mesa, there are major performance drops. First noticed the
issue with the 32bit steam game "Move or die", but it seems to affect the whole
system. It basically makes the game unplayable.

Bisecting pointed me to the following commit:

I tried reverting it, but it doesn't apply cleanly.


Running Arch Linux 64
Linux 4.11.2

System the issue was tested on:
- Arch Linux 64bit
- Linux 4.11.2, AMDGPU driver
- Radeon R9 285
