Comment 1 Mark Janes 2016-01-20 17:08:11 UTC
There more than 100 other dEQP tests that cause assertions on Haswell:


and the rest are in this category:

Those are most likely unrelated.

In addition to fixing the assertion failure, we should figure out why intel_miptree_copy_slice is being called, and see if we can avoid it.  I think that can happen due to texture relayout ("suddenly, miplevels!").  So it may be unavoidable.  But if we can, we should.
Comment 3 Neil Roberts 2016-01-21 19:03:41 UTC
I think this is just a case of the upper layers of Mesa incorrectly allowing an invalid texture and then the driver gets confused. I've posted a patch for it here:


And a Piglit test for it here:

Comment 4 Neil Roberts 2016-01-21 21:47:44 UTC
I've pushed the patch
