Thanks! Would you have an example of how to instantiate this bridge? Also, I imagine this bridge is right after the CPU I and D side ports and before any membus that Gem5 has internally right?

You can set up a "bridge" which will take a subset of addresses and route to a different gem5 port. If you can convert from the port interface to the AXI, then it should "just work".

You can set up a "bridge" which will take a subset of addresses and route to a different gem5 port. If you can convert from the port interface to the AXI, then it should "just work". Note that there are also already bindings to SystemC/TLM in gem5 as well that could serve as good examples.

The IP and memory (caches) will be memory mapped. So I’d like it if the Gem5 full system could handle some parts of the system (file IO, system calls) but route requests to certain memory address regions to an external port (I’ve taken care of the conversion from Gem5 port to AXI SystemC). Is this possible? _______________________________________________ gem5-users mailing list -- gem5-users@gem5.org<mailto:gem5-users@gem5.org> To unsubscribe send an email to gem5-users-le...@gem5.org<mailto:gem5-users-le...@gem5.org>
