My goal is to extract and print specific information (e.g., request type) from the Messages passing through the Garnet NetworkInterface instances. Within NetworkInterface::wakeup(), I’ve been able to print the messages by using: DPRINTF(RubyNetwork, "Message: %s\n", *(msg_ptr.get()));
In FS sims, I’m able to get messages printed such as: Message: [RequestMsg: addr = [0xb9a3cfc0, line 0xb9a3cfc0] Type = GETS AccessMode = Supervisor Requestor = L1Cache-1 Destination = [NetDest (20) - 0 0 - 0 1 - - 0 0 - 0 0 - - - - - - - - - - - - - - - ] MessageSize = Control DataBlk = [ 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 ] Len = 0 Dirty = 0 Prefetch = No ] Now here’s where I run into trouble. I’d like access to each individual field of the request Message, instead of printing it as output. I’ve tried dynamically casting to RubyRequestType and accessing the getType() method, but this does not work: Is there a better way to access the message attributes and enums within the garnet network from Ruby/SLICC code? Thanks in advance, Vlad
