Hi all, You can in principle try to setup an SMT simulation for the O3CPU by tweaking the smt parameters of the CPU [1] In practice this has not been tested in a long time and it is very likely it is broken.

I just would like to know if gem5 supports SMT for Full System > simulation in ARM ISA. Not as far as I know. This has to do with the underlying generic models used in gem5. They are customized to each instruction set by fiddling parameters, adding functional units, etc., and of course the instruction formats and actions can be adjusted. But the nature of the models (in-order, out-of-order) are the same. If I am wrong I'm sure someone will correct me!
