[PATCH 08/12] drm/nouveau/graph: enable when using external firmware

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
