Hi all, I observed that `cyclictest --smi` doesn't work on Raptor Lake CPUs (including 13th gen Intel Core CPUs). I assume that this could be resolved by extending the switch statements in has_smi_counter(). Last time this was done, the author changed the structure to better match turbostat.c, but that has since been refactored to a table/struct approach that is less easily copied. I also notice that if family == 6, all listed CPUs support the SMI counter, both in cyclictest.c and turbostat.c. Only unrecognized CPUs cause has_smi_counter() to return 0 if family == 6, even though it is more likely that the CPU is newer than the list in cyclictest.c, as opposed to a CPU from 2008 or earlier. What do you think about removing the checks on the model number, and assuming that all processors with family == 6 support the Nehalem MSRs, including the SMI counter? Any user running a recent cyclictest on pre-Nehalem hardware could still run without --smi to prevent seeing bogus SMI counts. Thanks in advance, Rodrigo
