You're right, there currently isn't support to do fast-forwarding for
SMT. One way to make it work would be to use multiple SimpleCPU
processors, one for each SMT context, then on the switchover have each
SimpleCPU map to one of the SMT contexts. That would require some
hacking though.

Dear all,
Under the SMT condition I am trying to make M5 fast-forwarding 100M
instructions first, and then do the statistic. I try to use the Sampler,
first use SimpleCPU to fast-forwarding 100M instructions, then use
DetailedCPU, but it seems that SimpleCPU doesn¡¯t support the SMT. (is
it correct?) . So I failed! Could you please tell me how to fast-ward
instructions under SMT condition? (Maybe use other kinds of CPU type to
fast-ward?)
Thank you very much!
