[RFC PATCH 0/4] *** Half-cooked vhost-pci implementation patch ***

[Wei Wang <wei.w.wang@intel.com>]

As the design patches to the spec are in discussion, I'm sending out the
draft code to show how the vhost-pci deign works.

Comments on the implementation are also very welcommed. Thanks.

Code base: v2.7.0 (git: df03468cad)

Wei Wang (4):
  qemu-char: add the "1-server-N-client" support
  vhost-user: add the vhost-user extension to support the vhost-pci
    based     inter-vm communication
  vhost-pci-net device support
  vhost-user: extend the vhost-user Master (client) part to support    
    vhost-pci
