Following cases also segfault: igt/gem_concurrent_blit/cpu-gpu-read-after-write-interruptible igt/gem_concurrent_blit/gtt-gpu-read-after-write igt/gem_concurrent_blit/gtt-gpu-read-after-write-interruptible igt/gem_concurrent_blit/prw-gpu-read-after-write igt/gem_concurrent_blit/prw-gpu-read-after-write-interruptible bisect shows:78865847f9fae7e590960f9836f2ec8b611a190e is the first bad commit commit 78865847f9fae7e590960f9836f2ec8b611a190e Author: Daniel Vetter <daniel.vetter@ffwll.ch> AuthorDate: Mon Aug 19 07:23:49 2013 +0200 Commit: Daniel Vetter <daniel.vetter@ffwll.ch> CommitDate: Mon Aug 19 08:09:25 2013 +0200 lib/drmtest: skip fixtures after an igt_skip This way we can just enclose all igt_skip/igt_require calls into fixtures even when we have subtests, and still output correct SKIP message for all of them. Wohoo, magic! The only thing which doesn't work yet is enumerating failed subtests, but I think that should work out on top of this. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> output: Segmentation fault (core dumped) Reproduce steps: ---------------------------- 1. ./gem_concurrent_blit --run-subtest cpu-gpu-read-after-write
This was a fun one, but should be fixed now: commit 912a7d855600aadb937517ec5bab26bfd9b8953d Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Tue Aug 20 06:39:43 2013 +0200 tests/gem_concurrent_blit: Fix segmentation fault
