This patch introduces a mdev based hardware vhost backend. This backend is built on top of the same abstraction used in virtio-mdev and provides a generic vhost interface for userspace to accelerate the virtio devices in guest. This backend is implemented as a mdev device driver on top of the same mdev device ops used in virtio-mdev but using a different mdev class id, and it will register the

This RFC is to demonstrate below ideas, a) Build vhost-mdev on top of the same abstraction defined in the virtio-mdev series [1]; b) Introduce /dev/vhost-mdev to do vhost ioctls and support setting mdev device as backend; Now the userspace API looks like this: - Userspace generates a compatible mdev device; - Userspace opens this mdev device with VFIO API (including doing IOMMU
