            Bug ID: 94713
           Summary: [Gen8+] ES 3.1 Stencil texturing broken for
           Product: Mesa
           Version: git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/i965
          Assignee: idr at freedesktop.org

dEQP-GLES31.functional.stencil_texturing.format.stencil_index8_2d_array and
dEQP-GLES31.functional.stencil_texturing.format.stencil_index8_cube both fail
on Broadwell.  These tests simply create a stencil texture, then draw using a
shader that samples from it.  Something about multi-layered textures breaks.

No crazy blitting or packed depth/stencil stuff is involved - we simply have a
S8 texture and rely on the sampler's W-tiling capabilities.
