            Bug ID: 99974
           Summary: Pinned memory is extremely slow on Dolphin
           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: akz@tutanota.com
        QA Contact: dri-devel@lists.freedesktop.org

When running Dolphin with the OpenGL backend and pinned memory enabled, I get
terrible performance. Getting about 10-20fps in a 60fps game with pinned
memory, and full 60fps without it.

This was discussed on dolphin's IRC channel earlier today, and this PR was made
to disable it. If it gets committed you'll have to use a build without that
code to test it I think.

I'm using an RX460, Linux 4.10.0, mesa/llvm/xorg-server all built from git,
although it happens on older stable versions too.

Has it ever been fast? Even with a different GPU?
