I used\nRusty\u0027s lguest.c as the source for developing this part : this supplied\nme with witty comments I wouldn\u0027t be able to write myself.\n\nWhat it is not: vhost net is not a bus, and not a generic new system\ncall. No assumptions are made on how guest performs hypercalls.\nUserspace hypervisors are supported as well as kvm.\n\nHow it works: Basically, we connect virtio frontend (configured by\nuserspace) to a backend. The backend could be a network device, or a tap\ndevice. Backend is also configured by userspace, including vlan/mac\netc.\n\nStatus: This works for me, and I haven\u0027t see any crashes.\nCompared to userspace, people reported improved latency (as I save up to\n4 system calls per packet), as well as better bandwidth and CPU\nutilization.\n\nFeatures that I plan to look at in the future:\n- mergeable buffers\n- zero copy\n- scalability tuning: figure out the best threading model to use\n\nNote on RCU usage (this is also documented in vhost.h, near\nprivate_pointer which is the value protected by this variant of RCU):\nwhat is happening is that the rcu_dereference() is being used in a\nworkqueue item. The role of rcu_read_lock() is taken on by the start of\nexecution of the workqueue item, of rcu_read_unlock() by the end of\nexecution of the workqueue item, and of synchronize_rcu() by\nflush_workqueue()/flush_work(). In the future we might need to apply\nsome gcc attribute or sparse annotation to the function passed to\nINIT_WORK().
