Just means that in that space of memory the object got allocated doesn't need to be tested. So skipping. not a failure. (In reply to Rodrigo Vivi from comment #1) > Just means that in that space of memory the object got allocated doesn't > need to be tested. So skipping. not a failure. It has different result when run multiple rounds on one machine. It's difficult to track the result. The failure is able to reproduce on BYT latest -nightly(691817ae2a8f37cb1df33f21a6dd1c15a8832693) root@x-byt06:/GFX/Test/Intel_gpu_tools/intel-gpu-tools/tests# dmesg -r|egrep "<[1-4]>"|grep drm root@x-byt06:/GFX/Test/Intel_gpu_tools/intel-gpu-tools/tests# ./gem_bad_reloc --run-subtest negative-reloc IGT-Version: 1.8-g4e5c16c (x86_64) (Linux: 3.18.0-rc7_drm-intel-nightly_691817_20141202+ x86_64) Found offset 17035264 for 4k batch Test requirement not met in function negative_reloc, file gem_bad_reloc.c:90: Test requirement: gem_exec[0].offset < BIAS Subtest negative-reloc: SKIP (0.000s) root@x-byt06:/GFX/Test/Intel_gpu_tools/intel-gpu-tools/tests# ./gem_bad_reloc --run-subtest negative-reloc-lut IGT-Version: 1.8-g4e5c16c (x86_64) (Linux: 3.18.0-rc7_drm-intel-nightly_691817_20141202+ x86_64) Found offset 17035264 for 4k batch Test requirement not met in function negative_reloc, file gem_bad_reloc.c:90: Test requirement: gem_exec[0].offset < BIAS Subtest negative-reloc-lut: SKIP (0.000s) Pushed a work-around in i-g-t: commit 88ff1cec3a830fc467b91efb7e1dcdb4d82a0e17 Author: Damien Lespiau <damien.lespiau@intel.com> Date: Thu Dec 4 13:42:12 2014 +0000 gem_bad_reloc: Don't flip-flop between SKIP and PASS Here is a cheap way for this test to give consistent results. This doesn't change the usefulness of this test, hopefully.
