From f3a3fea973a145fe16f70866dcfc22c3c5322a91 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Thu, 24 Nov 2016 00:18:21 +0000 Subject: [PATCH] radv: force persample shading when required. We need to force persample shading when a) shader uses sample_id b) shader uses sample_position c) shader uses sample qualifier. Also since ps_iter_samples can now change independently of the rasterizer samples we need to move setting the regs more often.
