Intelligent Power Allocation for Consumer & Embedded Thermal Control - Ian Rickards, ARM Ltd

Sign up or log in to save this to your schedule and see who's attending!

This presentation will explain the new “Intelligent Power Allocation” (IPA) governor, part of the the Linux Thermal Framework that landed in mainline Linux 4.1. IPA provides accurate thermal control of passively-cooled advanced System-On-Chip (SoC) products such as multi-core mobile & embedded devices. It introduces new techniques to Linux such as SoC power consumption models, dynamic power allocation between parts of the SoC depending on workload, and a Proportional-Integral-Derivative temperature control algorithm. A live demo of IPA controlling temperature will be shown.
