OK, here's a patch that implements the virtio spec update that I sent earlier. It supercedes the PUBLISH_USED_IDX patches I sent out earlier. Support is added in both userspace and vhost-net. If you see issues or are just curious, you can turn the new feature off. For example: -global virtio-net-pci.event_idx=on -global virtio-blk-pci.event_idx=off Also, it's possible to try both vhost-net and virtio-net. Another part is adding support for 64 bit features in place. The high bits are actually unused, to test hack qemu to set some high bit. linux code is here: git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost.git vhost-net-next-event-idx-v3 git://git.kernel.org/pub/scm/linux/kernel/git/mst/qemu-kvm.git virtio-net-event-idx-v3 Changes from v1: - unify used and avail ring handling in a single feature bit - copy avail event idx fix from vhost-net Michael S.
