Yesterday I wrote about the DTPM framework installed for Linux 5.11 but eventually Linus Torvalds has decided not to adopt it out of the union window.
As mentioned in the previous article, it was installed a week past the Linux 5.11 merge window. The Dynamic Thermal Power Framework (DTPM) aims to be a higher level thermal frame for issues such as ensuring users do not burn themselves on hot appliances and complying with legal requirements that case / device temperatures will not. open above 45 degrees Celsius.
While that framework has been in the works for months and pushed out as a late drawing application for Linux 5.11 in the hopes that it would encourage more adoption of the code for the Linux 5.12 cycle, Linus Torvalds was not happy with its code so late. After initially questioning “substantially an unresolved issue”, he withdrew a revised union request that did not have the addition of a DTPM framework.
The DTPM-deployed PM solutions include a new C-state platform for Intel Snow Ridge processors and various other configurations. The DTPM framework itself now needs to wait for Linux 5.12 to enter through the next union window.
