From 2f8351a5ac7bb04482eebaa73d967f7527df4d18 Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Sat, 16 Jun 2012 16:34:50 -0700 Subject: [PATCH] i965: Don't set brw_wm_prog_key::iz_lookup on Gen6+. Sandy Bridge and later don't use this field, so there's no point in setting it. It can only cause harmful state-based recompiles.
