From 79ea0f4506995c010320d56cd9dbfbefa34ab6f2 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Thu, 30 Jan 2014 04:19:57 +0000 Subject: [PATCH] r600g: add support for geom shaders to r600/r700 chipsets (v2) This is my first attempt at enabling r600/r700 geometry shaders, the basic tests pass on both my rv770 and my rv635, It requires this kernel patch: http://www.spinics.net/lists/dri-devel/msg52745.html v2: address Alex comments.
