    Given that much of it is simply locked behind firmware... That's actually feasible

    Yeah, your big bad x86 CPU is just a coprocessor now. More and more things are becoming out of its control.

    I don't get it, why use DPTF if you can do just tune you intel-rapl-mmio constraints for TDP and boost times? Also there is are intel p_statest for freq and other settings

    Phoronix: Intel DPTF Adaptive Policy Being Reverse Engineered For Better Linux Ultrabook Support

    One of the areas of Intel's Linux support that has been less than ideal is their handling of the Dynamic Platform and Thermal Framework (DPTF) for today's ultrabook. Intel has provided some support with a focus on Google's Chromium OS but it's less than complete and notably missing is support for the more advanced "adaptive policy", but that soon could change...
