vuart - An inter-partition data link service. port 0: PS3 AV Settings. port 2: PS3 System Manager.
The vuart provides a bi-directional byte stream data link between logical partitions. Its primary role is as a communications link between the guest OS and the system policy module. The current HV does not support any connections other than those listed.

ps3_vuart_read - The entry point for reading data from a port.
Queue data waiting at the port, and if enough bytes to satisfy the request are held in the buffer list those bytes are dequeued and copied to the caller's buffer. Emptied list buffers are retiered. If the request cannot be statified by bytes held in the list buffers -EAGAIN is returned.

ps3_vuart_write - the entry point for writing data to a port : The struct ps3_system_bus_device instance.
If the port is idle on entry as much of the incoming data is written to the port as the port will accept. Otherwise a list buffer is created and any remaning incoming data is copied to that buffer. The buffer is then enqueued for transmision via the transmit interrupt.
