Hello everyone, I continue thinking about heterogeneous architectures, in the gem5 web page I read something interesting: "Multiprocessor / multi-system capability. Thanks to gem5's object orientation, instantiation of multiple CPU objects within a system is trivial. Combined with the snooping coherence protocol supported by the caches, gem5 can model symmetric and asymmetric multiprocessor systems." But the only real reference to AMP is a workshop from Antony Gutierrez, http://www.m5sim.org/wiki/images/d/da/Gutierrez_gem5_workshop_2012.pdf. But he showed how to define ARM processors. I would like to know how to do something similar with x86, I want to simulate something like the Intel quickia. Do you think, is it possible?

Hello everyone, I need to work with asymmetric multiprocessors, reading different papers and questions in the forums I conclude that people who have worked with AMP and gem5 have done it using ARM. I need to work with x86, the key idea is to have complex cores without any modification and basic cores, the basic cores will not have floating point unit, branch predictors and a smaller private cache than complex cores. I would like to know if is it possible to do this in gem5? I really appreciate any suggestion and reply.
