Hi folks. I'd like to propose adding a new type of message to the packet.proto format used for protobuf memory traces.
Currently, packet IDs are opaque numbers which in some hand wavy way "identify" a packet, presumably to say where that packet came from (instruction, bus master, etc.) Currently there is no in-channel way to map those numbers to something more useful like an object name. What are people's thoughs as far as adding a new message type which would provide that information? Off the top of my head, it would make sense to have a single message per ID, and to have a single "string" type field which would be used to describe the meaning of the ID in whatever way was appropriate. I haven't thought through the specifics very much, so suggestions would be very appreciated. Currently I've got a hacky side-channel way to preserve that information, but it would be less fragile and inconvenient if that was preserved directly in the trace itself. Also, would this warrant a new file format version number, or would the fact that the additional messages can be ignored with no ill effect let us keep it at the same number?
