Hi

Even though this feature is super useful for hardware enabling, we ended up not
enabling it on BDW, so we still silently hit some unclaimed registers on this
platform. This series first fixes the bugs fround by the feature, then
introduces the feature later. It also introduces some rework on the unclaimed
register code, and I'd like to hear opinions and suggestsions about it.

Also notice that a patch to detect unclaimed registers on BDW was also sent to
this list on Feb 21.

I tested these patches briefly before my BDW machine died. They worked at that
time, so I hope they keep working now. Anyway, reviewers and QA should catch
anything wrong with these, right? :)

Thanks,
Paulo

drm/i915: reorganize the unclaimed register detection code
drm/i915: BDW can also detect unclaimed registers
