From e639385064663ba401544de5dbd463fa7f6cce2d Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Thu, 8 Nov 2012 04:13:26 -0800 Subject: [PATCH] i965: Fix AA Line Distance Mode in 3DSTATE_SF on Ivybridge. We were accidentally setting bit 14 in DWord 2 (which is Reserved/MBZ) rather than bit 14 in DWord 3 (which is AA Line Distance Mode). There's also no reason to ever set it to legacy mode; the bit is only used when drawing antialiased lines anyway. Set it unconditionally. NOTE: This is a candidate for stable branches.
