From 3d5b2d3b3bdc9aced3e625dd25f0649340375eae Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Mon, 7 Aug 2017 07:39:41 +0100 Subject: [PATCH] radv: fix MSAA on SI gpus. This ports the workaround from radeonsi, that was missing in radv. This fixes Talos rendering when MSAA is enabled on my Tahiti card.
