During engine setup, we may find that some engines are fused off causing a misalignment between internal names and the instances seen by users, e.g. (I915_ENGINE_CLASS_VIDEO_DECODE, 1) may be vcs2 in hardware. Normally this is invisible to the user, but a few debug interfaces (and our own internal tracing) use the original HW name not the name the user would expect as formed from their class:instance tuple. Replace our internal name with the uabi name for consistency with, for example, error states. v2: Keep the pretty printing of class name in the selftest Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=111311 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Mika Kuoppala <mika.kuoppala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190807110431.8130-1-chris@chris-wilson.co.uk
