Maybe over the top: Exposing a list of marketing features ( why are
e.g. watermark levels not in there - it seems completely arbitrary)
and then debug issues by randomly whacking those until insight hits
you isn't systematic debugging. And I don't want to enshrine that kind
of random whacking into ABI as the recommended way to debug i915.ko
issues.
