In order to fix several regression failures [1] the master/slave terminology in src/cpu/BaseCPU.py was reintroduced [2]. This patch is addressing the issue by providing 2 different ways of connecting cpu ports: *) connectBus: The method assumes an object with a bus interface is passed as an argument, therefore it tries to bind cpu ports to the bus.mem_side_ports and bus.cpu_side_ports *) connectAllPorts: No assumption on the port owning device is made. The method simply accepts ports as arguments which will be directly connected to the peer cpu ports This will be used for example by ruby Sequencers [1]: https://gem5.atlassian.net/browse/GEM5-775 [2]: https://gem5-review.googlesource.com/c/public/gem5/+/34495 Change-Id: I715ab8471621d6e5eb36731d7eaefbedf9663a71 Signed-off-by: Giacomo Travaglini <giacomo.travaglini@arm.com> Reviewed-on: https://gem5-review.googlesource.com/c/public/gem5/+/52584 Tested-by: kokoro <noreply+kokoro@google.com> Maintainer: Bobby R.
