Ok, I think I've addressed all comments so far here, and it still seems to work :). Please take a look. I basically ended up accepting all Rusty's suggestions, except I did not get rid of avail_idx field in vq: I don't (yet?) understand what's wrong with it, if any, and it seems required for correct implementation of notify on empty. I tried adding comment where it's changed

This patch-set introduces a new virtio type "rproc_serial" for communicating with remote processors over shared memory. The driver depends on the the remoteproc framework. As preparation for introducing "rproc_serial" I've done a refactoring of the transmit buffer handling. NOTE: These two patches are identical to first two patches of the V8 patch-set, but are rebased to

From: Shirley Ma <mashirle at us.ibm.com> This adds experimental zero copy support in vhost-net, disabled by default. To enable, set the zerocopytx module option to 1. This patch maintains the outstanding userspace buffers in the sequence it is delivered to vhost. The outstanding userspace buffers will be marked as done once the lower device buffers DMA has finished. This is monitored

What it is: vhost net is a character device that can be used to reduce the number of system calls involved in virtio networking. Existing virtio net code is used in the guest without modification. There's similarity with vringfd, with some differences and reduced scope - uses eventfd for signalling - structures can be moved around in memory at any time (good for migration, bug work-arounds
