            Bug ID: 106738
           Summary: No test for miptrees with DRI modifiers
           Product: Mesa
           Version: git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/i965
          Assignee: intel-3d-bugs at lists.freedesktop.org
          Reporter: nanleychery at gmail.com
        QA Contact: intel-3d-bugs at lists.freedesktop.org

We currently have a bug in i965 related to modifiers. If the driver imports a
tiled bo with a pitch >= 2^15 bytes, the driver will "retile" it to linear
during miptree creation. I'll be sending out a fix for this soon.

As far as I'm aware, there isn't a framework that can be used to test this
issue. We should have a test to prevent a similar issue from occuring again.
