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
