https://bugs.freedesktop.org/show_bug.cgi?id=37028 --- Comment #14 from Pierre-Eric Pelloux-Prayer <pelloux@xxxxxxxxx> 2011-06-07 10:19:00 PDT --- Remote debugging is hard :-/ Anyway, your modified app is wrong I think (not only the != / == inversion) : The app is supposed to : - draw a cube to a random position - use query to count how many pixels were drawn (so this number change every time the cube position changes) - then it compares the result of all queries : if not equal it fails Now I have no idea why it crashes on your system, did you try to debug it ? maybe there's an obvious mistake in it ? or maybe you could try to reduce the num_queries param ? The issue you've seen with values obviously wrong in 'r600_query_result' is the problem the patch is supposed to address. Without the patch, the 'size' variable is wrong (too big) and the 'results' buffer is read too far. Last, if you have piglit installed, I found a test case in it probably more robust than my simple app : occlusion_query. This test sometimes fails when using non-patched git mesa like this : $ ./bin/occlusion_query -auto samples passed = 400, expected = 400 samples passed = 0, expected = 0 samples passed = 2600, expected = 2600 samples passed = 2147483647, expected = 0 [<- ERROR] samples passed = 400, expected = 400 [...] PIGLIT: {'result': 'fail' } -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
