From cf9b31f78a545ede480c2dc25937a07a96cf6656 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Christian=20K=C3=B6nig?= Date: Thu, 21 Mar 2013 18:30:23 +0100 Subject: [PATCH] radeonsi: add start instance support MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This works different than on R600, we need to add the start instance manually.
