Author: Kenneth Graunke <[email protected]> Date: Fri Oct 21 01:03:37 2011 -0700 i965: Apply post-sync non-zero workaround to homebrew workaround. In commit 3e5d3626, Eric added a homebrew workaround to fix GPU hangs in the Mesa "engine" demo and oglc's api-texcoord test. Unfortunately, his PIPE_CONTROL contains a Depth Stall, which necessitates the post-sync non-zero workaround, Fixes GPU hangs in Civilization 4, PlaneShift, Minecraft, Neverwinter Nights, 3DMMES, and hopefully Heroes of Newerth as well.
