Description Martin Peres 2019-03-12 13:59:28 UTC

After updating mesa from 18.0.5 to 18.2.2, our SKL and GLK piglit machines (https://intel-gfx-ci.01.org/hardware.html#pigs) started consistently failing both "spec@ext_framebuffer_multisample_blit_scaled@blit-scaled samples=2" and "spec@ext_framebuffer_multisample_blit_scaled@blit-scaled samples=2 with gl_texture_2d_multisample_array".

The piglit version is a little old though: fdc5a4ca11124ab8413c7988896eec4c97336694

Here are the logs from the GLK platform when running "spec@ext_framebuffer_multisample_blit_scaled@blit-scaled samples=2":

Testing Intel-specific behavior.
Left Image: multisample scaled blit using extension.
Right Image: multisample scaled blit using shader program.

Comment 2 Lionel Landwerlin 2019-03-12 14:11:04 UTC

Could at least update to last stable?
For 18.2 that would be 18.2.8 and if you feel adventurous maybe attempt 18.3.4.

Comment 3 Mark Janes 2019-03-12 16:09:37 UTC

This test is reliable on i965 Mesa CI.  The last status change for these tests was 3 years ago.

If the failure is reliable, then a bisect should provide the information that we need to figure out what happened.
