[Mesa-dev] [PATCH v3 0/3] GEM BO padding to find OOB buffer writes

2018-01-26 Thread kevin . rogovin
From: Kevin Rogovin This patch series adds a new debug option to pad each GEM BO allocated by the brw_bufmgr with (weak) pseudo-random noise values which are then checked after each batchbuffer dispatch to the kernel. This can be quite valuable to find diffucult to track down heisenberg style bug
