From 4ce103e01a8959d604d1de9b99e627b95ffaec45 Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Wed, 10 May 2017 19:39:36 -0700 Subject: i965: Rework Sandybridge 3DSTATE_VIEWPORT_STATE_POINTERS. On Gen7+ we emit 3DSTATE_VIEWPORT_STATE_POINTERS_{SF_CL,CC} when emitting a new viewport. This patch makes us take the same approach on Sandybridge - but because we have a combined command, we just set the appropriate "change" bits. This eliminates an atom, some dirty flagging, and some brw->*.vp_offset writes. It does mean we'll emit two 3DSTATE_VIEWPORT_STATE_POINTERS instead of one if both change, but that's probably fine.
