Changeset 11763:0b76489963ee --------------------------- misc: Add support for switching multiple cores in SystemC This patch adds a '-n' flag to the gem5 SystemC driver which allows multiple CPUs to be switched out to a new CPU. Primarily this involves appending CPU numbers to the objects searched for in the config manager if there are multiple CPUs in the system. Note that an equivalent change should be made to the util/cxx_config driver, but I wanted to get input on this first before making the same change over there

Seems OK to me, although I don't use the System C interface. Do any others have any feedback? If I don't hear anything by Friday, I'm going to push.
(There's some minor formatting issues, but I'll take care of it before I push, and I'll update the comment below unless I hear otherwise.)

I believe it cannot be called before old_cpu.switchOut(). takeOverFrom() assumes the system state is "Drained", which happens during switchOut() IIRC.
Ship It!
