To see how to integrate with gem5's systemc kernel, look at the examples in util/systemc/systemc_within_gem5/ (not a great place for examples, I know). To use TLM, you can take a look at the TLM/gem5 bridge in src/systemc/tlm_bridge/. That's not intended as an example, but it's relatively simple and will show you the nuts and bolts of how that goes together. You'll also likely want to use the bridges to connect to other components of the simulator. That should give you a pretty good overview of the basics, and then most of the other concepts you'll likely need to understand are just vanilla gem5 sorts of things like writing config scripts.
If you don't yet have a TLM/systemc interface and it would be an equal amount of effort to make one vs. making a native gem5 interface, there is a tradeoff there. A native gem5 interface will have a little bit better performance, but it will be less portable than a TLM interface if you wanted to use it with something outside of gem5 in the future.
