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. -- You are receiving this mail because: You are the assignee for the bug.
