[PATCH 1/2] drm/i915: Don't try to disable host RPS when this was never enabled.

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

 



Specially in GT reset case this could be triggered and try
to disable things that had never been enabled. Let's add
some protection here.
