This can be used by userspace to map the OA reports received in the i915 perf samples with their associated ctx's (The OA reports have the hw ctx ID information embedded for Gen8+). Otherwise the userspace has no way of maintaining this association, since it has the knowledge of only per-drm file specific ctx handles.
