From cd2a24a4c2cf3aab8cbaf831d9712bc3c09cba66 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Thu, 29 Dec 2011 23:37:17 -0800 Subject: [PATCH] i965/gen7: Enable transform feedback as long as kernel support is present. The last major issue (intervening-read) is fixed, so let's turn this on for real. The only other known issue is a hardware limitation for tesselation with flat shading.
