From 7ec5e883f20a7ed88c23a98c4be8d4a4ea06e81e Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Wed, 29 Jan 2014 00:17:15 +0000 Subject: [PATCH] r600g: fix up shader out misc stuff for copy shader set the correct values so the misc out register is setup correctly for the copy shader. This also updates the state for the gs copy shader so the hw gets programmed correctly.
