From b7c852a646b12051e61c4dde4ddaa6c14af9c80b Mon Sep 17 00:00:00 2001 From: Alexandre Courbot Date: Fri, 2 May 2014 18:32:39 +0900 Subject: [PATCH] drm/nouveau/graph: enable when using external fw nvc0_graph_ctor() would only let the graphics engine be enabled if its oclass has a proper microcode linked to it. This prevents GR from being enabled at all on chips that rely exclusively on external firmware, even though such a use-case is valid. Relax the conditions enabling the GR engine to also include the case where an external firmware has also been loaded. Also switch to external firmware if the graph class has no microcode linked to it.
