Using the --smi option with cyclictest on ice lake processors gives the following error: FATAL: SMI counter is not supported on this processor It looks like the ice lake model (0x6A) is missing from function has_smi_counter: https://git.kernel.org/pub/scm/utils/rt-tests/rt-tests.git/tree/src/cyclictest/cyclictest.c#n410 Before submitting a patch for this, I was just wondering if there was a better way to handle this than having to update cyclictest every time a new processor model is released?
