...e driver has outstanding granted pages, then the module can't be immediately unloaded, because you can't free the pages if dom0 has a reference to them. My thought is to add a simple kernel thread which takes ownership of unwanted granted pages: it would periodically try to ungrant them, and if successful, free the page. That means that netfront could hand ownership of those pages over to that thread, and unload immediately. Performance measurement and tuning By design, the paravirt-ops-based Xen implementation should have high performance. It uses batchin...
