Description
Modern System-on-Chip designs increasingly incorporate built-in hardware thermal controllers to manage thermal conditions efficiently. Intel platforms, beginning with the Lunar Lake generation, feature integrated platform temperature controllers capable of autonomous thermal management. However, not all platform designs directly interface temperature readings and thermal thresholds with these hardware governors, limiting their effectiveness.
This presentation introduces a kernel-level approach that leverages existing thermal zone infrastructure to provide temperature data and threshold information directly through a new hardware thermal governor, bypassing user space interactions.
A proof-of-concept implementation will be demonstrated, showcasing the integration of thermal zones with hardware-based thermal control mechanisms.
