From 6b2010df7d55ad9feacbbcf708a83a66cdf91aaf Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Sat, 9 Apr 2011 01:16:06 -0700 Subject: [PATCH] i965: Initial Ivybridge VS state. Copied from gen6_vs_state.c; reuses create_vs_constant_bo from there. The 3DSTATE_VS command is identical but 3DSTATE_CONSTANT_VS is not.
