From 2a638076165eaa1294708a7e4518c2d72560e066 Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Mon, 6 Jun 2011 10:35:58 -0700 Subject: i965/gen7: Don't emit 3DSTATE_GS_SVB_INDEX on Ivybridge. According to vol2a.07, it only applies from Cantiga to Sandybridge. I found this in my ringbuffers while investigating various GPU hangs. While it may not have been the cause, it seemed wise to remove it.
