Description Kenneth Graunke 2016-03-09 01:00:27 UTC 
The dEQP-GLES3.functional.fbo.blit.rect.nearest_consistency_* tests fail.

Setting the "address rounding" bits in SAMPLER_STATE, even for GL_NEAREST filtering, appears to fix these tests, but breaks others (e.g. dEQP-GLES3.functional.shaders.texture_functions.textureprojlod.usampler3d_vertex).

fixes all the tests, but it's immensely sketchy.
Comment 2 Kenneth Graunke 2016-03-29 00:35:00 UTC 
I ended up pushing that patch despite its sketchiness.

    i965: Set address rounding bits for GL_NEAREST filtering as well.
Comment 3 Kenneth Graunke 2016-03-30 20:04:35 UTC 
I had to revert the patch as it caused dEQP regressions on Sandybridge (apparently my CI build doesn't test those).
Comment 4 Mark Janes 2016-04-25 18:17:38 UTC 
This was fixed by mesa 935ce14
