[Xen-devel] [PATCH 0/5] RFC: V4V (v3)

[Jean Guyader <jean.guyader@xxxxxxxxxx>]

v3 changes:
        - Switch to event channel
                - Allocated a unbound event channel
                  per domain.
                - Add a new v4v call to share the
                  event channel port.
        - Public headers with actual type definition
        - Align all the v4v type to 64 bits
        - Modify v4v MAGIC numbers because we won't
          but backward compatible anymore
        - Merge insert and insertv
        - Merge send and sendv
        - Turn all the lock prerequisite from comment
          to ASSERT()
        - Make use or write_atomic instead of volatile pointers
        - Merge v4v_memcpy_to_guest_ring and
          v4v_memcpy_to_guest_ring_from_guest
                - Introduce copy_from_guest_maybe that can take
                  a void * and a handle as src address.
        - TODO:
                - Add libv4v userspace code

v2 changes:
        - Cleanup plugin header
        - Include basic access control
        - Use guest_handle_for_field
