Heating, much power consumption, lack of scheduling files

My rolling 5.0 (Jan. 2019) heats when idle or works not much. There are no

     sched_mc_power_savings     and

     sched_smt_power_savings

kernel files in /sys/devices/system/cpu/ , so it is impossible to turn on scheduling.

This is problem for laptops users - shorter battery cycle (and unnecessary planet warming - for all).

Would you set

     CONFIG_SHED_MC     to 'y'     and

     CONFIG_SHED_SMT   to 'y'

every time you compile new rolling version ?

One more time like above.

Do your rolling or next releases blow warm when nothing to do ?

Setup requires installing additional tazpkgs:

cpufrequtils and powertop

linux-cpufreq and linux-acpi for required kernel modules.
