>     
>     i915_hws_info() has not been kept upto date (missing new engines) and so
>     I consider it to be unused. HWS is included in the error state, which
>     would be an avenue to retrieving it if required in future (possibly via
>     i915_engine_info). As it is currently oopsing with an rpm testcase, just
>     remove it.

Elio, please re-test and confirm status.
Thanks
