[Xen-devel] [PATCH 0/5] RFC: V4V (v2)

[Jean Guyader <jean.guyader@xxxxxxxxxx>]

V4V is a copy based inter vm communication system.

Please have a look at this thread for more detail
about V4V.
http://lists.xen.org/archives/html/xen-devel/2012-05/msg01866.html

This patch series is work in progress but I wanted to
post it early enough so I can get feedback from people.

v2 changes:
  - Cleanup plugin header
  - Include basic access control
  - Use guest_handle_for_field
changes requested not a v2:
  - Switch to event channel instead of virq

Jean Guyader (5):
  xen: add ssize_t
  v4v: Introduce VIRQ_V4V
  xen: Enforce introduce guest_handle_for_field
  xen: Add V4V implementation
  v4v: Introduce basic access control to V4V
