It's nice plan. We should do it. In my understanding, the following drivers could be merged into a single virtio PMD since they consist of similar code for handling the virtio ring. - librte_pmd_virtio - librte_pmd_xenvirt - librte_vhost (cuse) librte_vhost is not a PMD, but we can easily write a librte_pmd_vhost based on librte_vhost. Before doing it, we need to consider vhost-user extension for librte_vhost. BTW, I have a RFC patch for librte_vhost to handle vhost-user. It may be the first step to merge all virtio drivers. My patch introduces an abstraction layer to hide differences between legacy cuse vhost and vhost-user from DPDK apps. Also in my patch, virtio negotiation and initialization code and virtio handling code is separated. So, legacy cuse vhost and vhost-user can share virtio handling code Anyway, I will send a RFC patch soon as the first step of merging all virtio drivers. Thanks, Tetsuya
