Hey folks, I've been working on custom instructions for RISC-V within Gem5 and am able to manage basic logic. However, I'd like to implement a custom component that interfaces with these new instructions and I'm having trouble figuring out where to start. The custom instructions doc <https://www.gem5.org/documentation/general_docs/architecture_support/isa_parser/> doesn't give much information. I can see other types of instructions like AtomicOps can get called but it's not clear how to extend this to my own C++ class. Are there any examples out there? If I have a CustomAdd instruction which interfaces with a CustomAdder object, how do I connect the decoder.isa instruction to that logic? Thanks, Nick
