            Bug ID: 99228
           Summary: [G33]
                    tests fail
           Product: Mesa
           Version: git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/i965
          Assignee: chadversary at chromium.org
          Reporter: mark.a.janes at intel.com
        QA Contact: intel-3d-bugs at lists.freedesktop.org

Four related tests regressed on g33 at:

mesa/texformat: Handle GL_RGBA + GL_UNSIGNED_SHORT_5_5_5_1

_mesa_choose_tex_format() already handles GL_RGBA +
by converting it to MESA_FORMAT_B5G5R5A1_UNORM. Teach it do the same for
the non-reversed type. Otherwise, the switch's fallthrough converts it
to an 8888 format, which has incompatible precision in the alpha

Patch 2/2 to fix
on Intel.
