Question on EPT traits

Question on EPT traits

I just needed a clarification on the EPT trait selection (vol 3b, 25.2.4 "EPT and Memory typing"). The spec suggests that MTRRs are not involved in the determination of the final memory type. Does this include the SMRR (system management range register) too ? Are the traits from SMRR ignored ? Thanks for your help.
