 \section{Discussion}\label{sec:sw-coherency-discuss}
 % - you should also measure the access latency after coherency operation, though this is impl-specific (e.g., one vendor can have a simple PoC mechanism where e.g. you have a shared L2-cache that is snooped by DMA engine, hence flush to L2-cache and call it a day for PoC; but another can just as well call main mem the PoC, dep. on impl.)
