            Bug ID: 103549
           Summary: [HSW] Linux 4.13 CTS regressions
           Product: DRI
           Version: DRI git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: critical
          Priority: medium
         Component: DRM/Intel
          Assignee: intel-gfx-bugs at lists.freedesktop.org
          Reporter: mark.a.janes at intel.com
        QA Contact: intel-gfx-bugs at lists.freedesktop.org

During deployment of a new Haswell device to Intel's Mesa CI, we found that
many tests fail for Linux 4.13.  Using the stock 4.9 kernel, the same tests
pass.

About 100 tests fail on the newer public kernel, eg:
ES31-CTS.functional.texture.gather.offset_dynamic.min_required_offset.2d.depth32f.size_npot.compare_greater.mirrored_repeat_clamp_to_edge
ES31-CTS.functional.texture.gather.offset_dynamic.min_required_offset.2d.depth32f.size_npot.compare_less.repeat_mirrored_repeat

Standard Output

Using a framebuffer object with renderbuffer with format GL_RGBA8 and size (64,
64)
Note: texture level's size is (17, 23)
Texture base level is 0
s and t wrap modes are GL_MIRRORED_REPEAT and GL_CLAMP_TO_EDGE, respectively
Minification and magnification filter modes are GL_NEAREST and GL_NEAREST,
respectively (note that they should have no effect on gather result)
Using texture swizzle [default swizzle state]
Using texture compare func GL_GREATER
Texture coordinates run from (-0.3, -0.4) to (1.5, 1.6)


About 100 analogous Vulkan CTS tests fail as well.
