From e8d297b7a108fcf1cb688fe1db89e83b8f85e091 Mon Sep 17 00:00:00 2001 From: Chia-I Wu Date: Tue, 16 Jun 2015 23:11:06 +0800 Subject: ilo: add 3DSTATE_VF to ilo_state_vf 3DSTATE_VF specifies cut index enable and cut index. Cut index enable is specified in 3DSTATE_INDEX_BUFFER instead prior to Gen7.5.
