For Linux you have much more control if you wanted to control the power envelope yourself. you can use the sysfs interface for the intel-rapl driver to adjust the power limits: Eg you can set your PL1 (long term) and PL2 (short term) power limits in uW: echo 1 > /sys/class/powercap/intel-rapl:0/enabled #PL1 echo 28000000 > /sys/class/powercap/intel-rapl:0/constraint_0_power_limit_uw #PL2 echo 64000000 > /sys/class/powercap/intel-rapl:0/constraint_1_power_limit_uw

From what I have found there is not a good way for the major window managers to control power profiles that are built into gnome/kde/etc. But it would be interesting to explore more. You can read about the interface here, it is pretty cool because you can also use this to monitor power usage too: https://www.kernel.org/doc/html/latest/power/powercap/powercap.html

There are a few mentions of intel projects for linux.
