Changeset 11798:3a490c57058d --------------------------- misc: Clean up and complete the gem5<->SystemC-TLM bridge [5/10] The current TLM bridge only provides a Slave Port that allows the gem5 world to send request to the SystemC world. This patch series refractors and cleans up the existing code, and adds a Master Port that allows the SystemC world to send requests to the gem5 world. This patch: * Introduce transactor modules that represent the gem5 ports in the * SystemC world. * Update the SimControl module and let it keep track of the gem5 ports.
