    Phoronix: A New Linux Kernel Framework To Help Ensure You Don't Burn Yourself On Hot Devices

    Linaro is working on the DTPF framework for the Linux kernel for meeting legal requirements around the maximum allowed case/contact temperature of devices...

    You mean DTPM?

      Intel Dynamic Platform and Thermal Framework, although on that first sentence, there probably doesn't need to be the word framework following

        Will a sane framework be used across all devices for thermal control, including desktop PCs? Or is this going to be ARM only?

          Looks like that RocketLake + RTX 3000 smartphone I wanted is a go!

            The framework is designed to be architecture agnostic. The DTPM tree contains the generic code and the DTPM leaves of the tree are the real devices where it is possible to act on power limitation and get power usage. So any platform wanting to add a backend driver to hook the tree can use the DTPM framework. The Mobile with the ARM architecture and the thermal daemons are obviously the first ones on the list to use this framework, that is why there is the DTPM cpu energy model based submitted along with the DTPM generic framework.

            There is a blog giving more details on that: https://www.linaro.org/blog/using-en...in-tdp-budget/

            And a presentation at the Linaro Virtual Connect 20: https://www.youtube.com/watch?v=Ak6o...outu.be&t=9205

            Hope that helps

              But how am I supposed to make hot dogs if this is going to be on by default?

                Planned obsolescence provided as a safety measure, how clever.

                  Added to list of reasons to fork kernel for my anti-SJW distro.

                    Is there a legal requirement on maximum temperature?

                    So what? Is using a heater illegal now?
                    What if the room temperature is 45°C? Does that make using a phone/computer illegal?

                    Did we just break the law?
