Do you mean "used to pass"? If so, bisect. We find the culprit commit is commit 5340b6dff73a0a23531ce2a5f28fba8303adab6e. Maybe its makefile has some problem then, the i965_dri.so is always not built, which makes it run with software raster. This complexed our bisecting. Finally we will build the dri in its directory seperately, and find the culprit commit is a merge commit, and its parents commit works well. commit 5340b6dff73a0a23531ce2a5f28fba8303adab6e Merge: 9fd26da ee4c921 Author: Brian Paul <brianp@vmware.com> Date: Tue Feb 10 16:44:02 2009 -0700 Merge commit 'origin/gallium-master-merge' This is the big merge of the gallium-0.2 branch into master. gallium-master-merge was just the staging area for it. Both gallium-0.2 and gallium-master-merge are considered closed now. Conflicts: progs/demos/Makefile src/mesa/main/state.c src/mesa/main/texenvprogram.c Note: the failure is only in the GL_POLYGON mode. *** Bug 39669 has been marked as a duplicate of this bug. *** I've looked at this a bit more: the gen4 SF code doesn't do point handling for unfilled polygons. Hello Eric, Would you mind provide me a few pointers on the code section to look at, which you identified as problematic on gen4? I've presumed this would be one of the following based on your comment: - brw_sf.c - brw_sf_emit.c - brw_sf_state.c I'm not familiar with the code, but I suspect it's in brw_clip_unfilled.c -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.
