Move the header to be 8 bytes and include a unique identifier that can be use to correlate request to responses. Rename the msg_id field to msg_op as having a msg_id and msg_uid field and using identifiers in 2 contexts would have been unclear. Rework ID to OP and change wording message identifer to message operation to be coherent in the rest of the specification. Signed-off-by: Bertrand Marquis <bertrand.marquis@arm.com>
Add a sub-section to do a first explanation draft of how the message correlation is to be done using a combination of a message device number and the message unique identifier value. Signed-off-by: Bertrand Marquis <bertrand.marquis@arm.com>
Relax error handling in the virtio-msg bus and introduce wording to allow the virtio-msg bus to report error to the virtio-msg transport if a request could not be transmited or a malformed response was received. This prevents the need to generate dummy responses in the bus and make the specification coherent with the current Linux PoC implementation. Signed-off-by: Bertrand Marquis <bertrand.marquis@arm.com>
