Yesterday I wrote about the DTPM framework that is being submitted for Linux 5.11, but in the end, Linus Torvalds decided not to accept it from the merge window.
As noted in the previous article, it was shipped to the Linux 5.11 merge window within a week. The Dynamic Thermal Power Framework (DTPM) is intended to be a higher-level thermal framework for cases such as ensuring that users do not burn themselves on hot appliances and meets legal requirements that the temperature / exposed appliance temperatures do not exceed 45 degrees Celsius does not exceed.
While this framework was going on for months and was expressed as a late request for Linux 5.11 in the hope that it would encourage code for the Linux 5.12 cycle, Linus Torvalds was not happy with such a late code. After initially questioning the “very much an insoluble thing”, he finally submitted a revised merger request that did not add to the DTPM framework.
The PM fixes pulled without DTPM contain the new C-state table for Intel Snow Ridge processors and several other fixes. The DTPM framework itself will now have to wait until Linux 5.12 enters through the next merge window.
