Yesterday I wrote about sending the DTPM framework for Linux 5.11, but in the end Linus Torvalds decided not to accept it from the merge window.
As mentioned in the previous article, it was sent in a week after the Linux 5.11 merge window. The Dynamic Thermal Power Frame (DTPM) aims to be a higher level thermal frame for cases such as ensuring that users do not burn on hot devices and complying with legal requirements that the temperature of the exposed housing / devices does not exceed 45 degrees Celsius.
While that framework worked for months and was rejected as a late extraction request for Linux 5.11, in the hope that it will encourage more code adoption for the Linux 5.12 cycle, Linus Torvalds was not happy with the code so late. . After initially questioning “a very unresolved issue”, he finally submitted a revised merger application which did not add the DTPM framework.
PM fixes that were extracted without DTPM include the new C-state table for Intel Snow Ridge processors and various other fixes. The DTPM framework itself will now have to wait until Linux 5.12 to enter the next merge window.
