For Comet Lake to read PC10 residency, please use `perf` from linux-tools packages:

  $ perf stat -e cstate_pkg/c10-residency/ \
              -e cstate_pkg/c9-residency/ \
              -e cstate_pkg/c8-residency/
  (this will block until interrupted)

as `powertop` doesn't currently support CML, either.
