Description Tomi Sarvela 2018-05-23 08:04:46 UTC 
A couple of Intel-GFX-CI hosts started crashing in piglit tests when the following commits were taken in:

fae925a49 Specify an explicit window size in builtin uniform tests.
3ecdac456 Fix bogus assertions in builtin uniform test generator.

This might be an environment issue on CI, but marking as a behaviour change anyway.

All failing tests can be seen in directory level at https://intel-gfx-ci.01.org/tree/drm-tip/IGT_4491/pig-*
Approximately 28 tests fail on SKL, 26 on GLK, 6.5k on HSW and 4.5k on SNB.

Examples:

SNB https://intel-gfx-ci.01.org/tree/drm-tip/IGT_4491/pig-snb-2600/spec%40glsl-1.10%40execution%40built-in-functions%40fs-abs-float.html
HSW https://intel-gfx-ci.01.org/tree/drm-tip/IGT_4491/pig-hsw-4770r/spec%40arb_gpu_shader_int64%40execution%40built-in-functions%40cs-abs-i64vec2.html
SKL https://intel-gfx-ci.01.org/tree/drm-tip/IGT_4491/pig-skl-6600/spec%40glsl-1.10%40execution%40built-in-functions%40fs-acos-float.html
GLK https://intel-gfx-ci.01.org/tree/drm-tip/IGT_4491/pig-glk-j5005/spec%40glsl-1.10%40execution%40built-in-functions%40fs-acos-float.html

This piglit patch was reverted a couple of hours after the regression.

Thanks, we really need to stay on a fixed version of piglit that goes well with the mesa version we run.
