From 3cc0a7be23ab603ed40d602595f673a44e079885 Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Fri, 21 Oct 2011 01:03:37 -0700 Subject: 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, and 3DMMES. Hopefully Heroes of Newerth as well, though I haven't tested that. NOTE: This is candidate for the 7.11 branch.
