Hello everyone, This RFC implements packed ring support in virtio driver. Some simple functional tests have been done with Jason's packed ring implementation in vhost: https://lkml.org/lkml/2018/4/23/12 Both of ping and netperf worked as expected (with EVENT_IDX disabled). TODO: - Refinements (for code and commit log); - More tests; - Bug fixes; RFC v3 -> RFC v4: - Make ID allocation

First of all I would like to thank Mark for getting roundrobin to go roundrobin. Good job. Now we have some options here for leastrecent and fewestcalls strategy. It needs some work on the logic and Mark recommend that I ask the list and get some input before he makes any changes to it. fewestcalls from what I have seen would always ring the agent with the fewestcalls first then go into

Since we know vq->vring.num is a power of 2, modulus is lazy (it's asserted in vring_new_virtqueue()).

For virtualization, we've developed virtio_ring for efficient communication. This would also work well for userspace-kernel communication, particularly for things like the tun device. By using the same ABI, we can join guests to the host kernel trivially. These patches are fairly alpha; I've seen some network stalls I have to track down and there are some fixmes. Comments welcome!

Hello everyone, This RFC implements packed ring support for virtio driver. The code was tested with DPDK vhost (testpmd/vhost-PMD) implemented by Jens at http://dpdk.org/ml/archives/dev/2018-January/089417.html Minor changes are needed for the vhost code, e.g. to kick the guest. TODO: - Refinements and bug fixes; - Split into small patches; - Test indirect descriptor support; - Test/fix event

Hi folks! I have set up dsync replication with SSH according to http://wiki2.dovecot.org/Replication with the exception of having system users and calling doveadm dsync-server directly from authorized_keys, because the wrapper script posted on the above site is needless (at least in 2.2.10). However, while the two instances connect well to each other, no synchronisation is performed at all, the
