Chris Wilson 227213438a Revert "drm/i915: enable HiZ Raw Stall Optimization on IVB" ... This reverts commit 116f2b6da8. This optimization causes widespread corruption in games, and even in glxgears, on my ivb:gt1. The corruption appears like z-fighting of overlapping polygons in the HiZ buffer. The observation ties in very closely with the description of the optimization disabled by default on IVB: "The Hierarchical Z RAW Stall Optimization allows non-overlapping polygons in the same 8x4 pixel/sample area to be processed without stalling waiting for the earlier ones to write to Hierarchical Z buffer." No reason is given for why it is disabled by default, usually for such optimizations it is that it is incomplete. However, there is no indication whether this a gt1 only issue either. Before considering reenabling this optimization, I would first suggest reproducing the corruption in piglit.
