Power Management and Thermal Control Micro-conference

Not scheduled
LPC Microconference Proposals


The Power Management and Thermal Control Microconference focuses on power management and thermal control infrastructure, CPU and device power-management mechanisms, and thermal control methods. In particular, we are interested in improving the thermal control infrastructure in the kernel to cover more use cases and utilizing energy-saving opportunities offered by modern hardware in new ways.

The goal is to facilitate cross-framework and cross-platform discussions that can help improve energy-awareness and thermal control in Linux.

Prospective topics:

All of the topics listed above can benefit from face-to-face discussions at the LPC, especially as far as the time needed to reach the consensus is concerned for at least some of them.

The specific list of topics will be determined through the CfP for this microconference.

The list of key participants for this microconference is as follows: Srinivas Pandruvada, Zhang Rui, Daniel Lezcano, Len Brown, Morten Rasmussen, Ulf Hansson, Sudeep Holla, Peter Zijlstra, Rafael Wysocki.

Since LPC 2022 we have been focusing mostly on the thermal zone device registration improvements (Unified structure for thermal zone device registration) which comprised several patch series submissions and pull requests:

We have also done some work on scale-invariance improvements in accordance with an LPC 2022 topic Frequency-invariance gaps in current kernel:

Moreover, following an LPC 2022 topic Linux per cpu idle injection, the Intel powerclamp driver has been improved to allow more fine-grained idle injection based on the generic power-capping idle-injection mechanism:
