From: Paulo Zanoni <paulo.r.zan...@intel.com> We want to port FBC to the frontbuffer tracking infrastructure, but for that we need to know what caused the object invalidation/flush so we can react accordingly: CPU mmaps need manual, GTT mmaps and flips don't need handling and ring rendering needs nukes.
