            Bug ID: 93466
           Summary: [r600g] Emulate fp64 OpenCL operations using integer
                    arithmetic
           Product: Mesa
           Version: git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: medium
         Component: Drivers/Gallium/r600
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: rivanvx@gmail.com
        QA Contact: dri-devel@lists.freedesktop.org

For teaching and demonstration purposes it would be cool to have emulated fp64
arithmetic on low-end Evergreen and Northern Islands chips which don't support
it (e.g. Caicos). However slow it might end up being, it would be really useful
to have it at least for teaching GPU computing.
