Everyone knows why embedded SoCs should not overheat and why software has to monitor for rising temperatures and implement mitigation frameworks. But, should software monitor for falling temperatures as well? What if there are hardware limitations that impedes SoC operations at lower temperatures?

This presentation aims to give an overview of some hardware requirements in modern
SoCs, such as Qualcomm Snapdragon processors that call for monitoring of falling temperatures and corresponding mitigation needs. Further, the presentation explores how well suited(or not) the existing Linux Kernel thermal management frameworks are to handle this requirement. The presentation identifies the gaps in the existing frameworks and provides a first-pass solution to these gaps. Lastly the presentation discusses the status of few of these solutions that are already posted in the respective mailing lists.
