Hello, I am currently working on replicating a side-channel attack related to SMT port contention. I would like to clarify whether SMT is exclusively supported in SE mode or if it is also applicable for testing in FS mode. Any guidance or assistance on this matter would be greatly appreciated. Regards, Zelong
