5 Message queue is a simple low-capacity IPC channel between two virtual machines.
7 message queue is unidirectional and buffered in the hypervisor. A full-duplex

28 2. Gunyah raises the corresponding interrupt for VM_B (Rx vIRQ) when any of
32       queue is being used to implement an RPC-like interface.
38 3. VM_B calls gunyah_msgq_recv() and Gunyah copies message to requested buffer.
40 4. Gunyah raises the corresponding interrupt for VM_A (Tx vIRQ) when the message
