Hello Vlad, I don't think you can dynamically cast a Message pointer (MsgPtr) to RubyRequestType. Do you mean a RequestMsg pointer or a RubyRequest pointer?
If you used dynamic_cast in NetworkInterface.cc to cast a MsgPtr to a RequestMsg pointer, you should be able to call the getType function. (The function is defined in RequestMsg.hh.) But this function may not return the information you want. Depending on the protocol you are using, different fields are copied to a RequestMsg (which will eventually reach the network interface). The sm files corresponding to the protocol define which fields are copied. You will have to check the protocol you are using. For example, in src/mem/ruby/protocol/Garnet_standalone-cache.sm, the address, requestor, destination and message size are copied to the RequestMsg (out_msg). But the type is set to "CoherenceRequestType:MSG".
