From 0d6a722ec4df73595d4159e5b35c6fd61f847a6c Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Tue, 18 Dec 2012 13:45:14 -0800 Subject: [PATCH] i965: Add perf debug for depth/stencil alignment workaround. Fixing these rendering bugs has been implicated in performance regressions (which may be unfixable), but at least knowing that it's happening should help diagnose those regressions.
