[RFC PATCH v2 0/3] Introduce a PCIe endpoint virtio console
PCIe endpoint framework provides APIs to implement PCIe endpoint function.
This framework allows defining various PCIe endpoint function behaviors in
software. This patch extend the framework for virtio pci device. The
virtio is defined to communicate guest on virtual machine and host side.
Advantage of the virtio is the efficiency of data transfer and the conciseness
of implementation device
