This was a segfault, not a lockup, right? On my system it behaves a little bit different. I get a segfault from Blender, all the time, but it will only hang X sometimes. Jiewen, can you reproduce this on our G45? (In reply to comment #3) > Jiewen, can you reproduce this on our G45? > Our G45 get a segfault from Blender all the time, after that, if you run other 3D apps X will be hung. For me, it's hung X every time, tried maybe 8 times. meta_draw_quad does nasty things for the case that brw_draw_prims decides to do a sw fallback. I've got code to fix this in the meta-clear branch of my repo, but it's not correct yet. failure present as far back as 154a9e5317f890618932cea0129ef887e16baf84 commit 095c3a5cb16dae5c1e4cf85bffd3cb2465ab9e28 Author: Eric Anholt <eric@anholt.net> Date: Mon Dec 15 13:25:20 2008 -0800 i965: Update state before checking for fallbacks in brw_try_draw_prims. This got flipped around in 7855b2aef6bd9e9c2d73260b5cd166159b2525c6. Bug #18907. Thanks to idr for pointing me at a nicer testcase than blender. |
