I've changed the uapi for configuring the i915_oa specific attributes when calling perf_event_open(2) whereby instead of cramming lots of bitfields into the perf_event_attr config members, I'm now daisy-chaining a drm_i915_oa_event_attr_t structure off of a single config member that's extensible and validated in the same way as the perf_event_attr struct. I've found this much nicer to work with while being neatly extensible too.
This worries me a bit.. is there more background for this?
