Description Kenneth Graunke 2016-03-09 01:12:55 UTC 
The dEQP-GLES3.functional.clipping.line.wide_line_clip_viewport_center and dEQP-GLES3.functional.clipping.line.wide_line_clip_viewport_corner test cases both fail.

However, dEQP-GLES3.functional.clipping.line.wide_line_clip passes.
Comment 1 Kenneth Graunke 2016-03-09 09:52:29 UTC 
Disabling "Viewport XY Clip Test Enable" (GEN6_CLIP_TEST_XY) in 3DSTATE_CLIP makes these tests pass.  It seems like they're getting clipped away by the viewport.
Comment 2 Kenneth Graunke 2016-03-11 00:20:06 UTC 
I have a 5 patch series which fixes these bugs.  I'll send it to the list as soon as it passes regression testing.
