I've applied Kevins "GEM BO padding to find OOB buffer writes" patch series to master ef272b161e05e8216f2d1f4df5023f3aed0ae4fa from here... <a href="https://patchwork.freedesktop.org/series/35080/">https://patchwork.freedesktop.org/series/35080/</a> Replayed my trace file in a loop for >30 minutes with... INTEL_DEBUG=check_oob apitrace replay Downward.trace >> downward_debug.log 2>&1 The patch detected lots of "out-of-bounds write from brw_bo". "cat downward_debug.log | grep Detected" shows them all.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
