Subject[PATCH RFC 0/2] Packed ring for virtio
Date
Hello everyone,

This RFC implements a subset of packed ring which is described at
https://github.com/oasis-tcs/virtio-docs/blob/master/virtio-v1.1-packed-wd08.pdf

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.

It's not a complete implementation, here is what's missing:

- Device area and driver area
- VIRTIO_RING_F_INDIRECT_DESC
- VIRTIO_F_NOTIFICATION_DATA
- Virtio devices except net are not tested
- See FIXME in the code for more details

Thanks!

Best regards,
Tiwei Bie
