vringh: update for virtio 1.0 APIs ... When switching everything over to virtio 1.0 memory access APIs, I missed converting vringh. Fortunately, it's straight-forward. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Michael S. Tsirkin   commited 2014-12-15 23:49:28 +02:00	b9f7ac8c72
vringh: 64 bit features ... Pass u64 everywhere. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Michael S. Tsirkin   commited 2014-12-15 23:49:23 +02:00	b97a8a9006
virtio: Introduce vringh wrappers in virtio_config ... Add wrappers for the host vrings to support loose coupling between the virtio device and driver. A new struct vringh_config_ops with the functions find_vrhs() and del_vrhs() is added to the virtio_device struct. This enables virtio drivers to manage virtio host rings without detailed knowledge of how the vrings are created and deleted. The function vringh_notify() is added so vringh clients can notify the other side that buffers are added to the used-ring.

vringh: host-side implementation of virtio rings. ... Getting use of virtio rings correct is tricky, and a recent patch saw an implementation of in-kernel rings (as separate from userspace). This abstracts the business of dealing with the virtio ring layout from the access (userspace or direct); to do this, we use function pointers, which gcc inlines correctly.
