--- Comment #2 from Chris Wilson <chris at chris-wilson.co.uk> ---
Correct; that patch disables rc6 while active to prevent catastrophe. And yes,
no rc6 is itself pretty catastrophic.

Could you please do something like:

$ perf stat -a -x, -r 1 \
        -e "power/energy-pkg/" \
        -e "power/energy-cores/" \
        -e "power/energy-gpu/" \
        -e "i915/actual-frequency/" \
        -e "i915/rc6-residency/" \
        -e "i915/rcs0-busy/" \
        -e "i915/bcs0-busy/" \
        -e "i915/vcs0-busy/" \
  sleep 300

while you do your normal activities, and report before/after? (Trying to do the
same activity in each sample.)
