--- Comment #9 from Rafael J. Wysocki (rjw@rjwysocki.net) ---

I would use intel_pstate "powersave" (with the patch you have tested applied).

One more question, though.

I guess that you used "schedutil" with acpi-cpufreq as a scaling_driver?

If that's correct, can you please also try to run intel_pstate in the passive
mode (that is, pass "intel_pstate=passive" to the kernel command line) and use
"schedutil" with that (scaling_driver will show "intel_cpufreq" in that
configuration)?

With acpi-cpufreq "schedutil" may under-provision things due to the way in
which turbo P-states are represented in the ACPI tables.
