From 69d3bb99154285bb16e8ce0f5d5cefed0d395a15 Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Thu, 1 Sep 2016 22:01:47 -0700 Subject: [PATCH] intel/isl: Handle HiZ and CCS tiling more directly The HiZ and CCS tiling formats are always used for HiZ and CCS surfaces respectively. There's no reason why we should go through filter_tiling and it's much easier to always get HiZ and CCS right if we just handle them directly.
