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
