Power Management

Linaro power management team aims to bring consistency and to reduce fragmentation of power management solutions in the Arm SoC-Linux ecosystem. Members of this team collaborate with open source Linux community, Arm and other member companies to understand diverse requirements pertaining to power management solutions and actively tries to bridge the gap between conflicting solutions.

The team primarily offers comprehensive solutions to complex problems surrounding power management frameworks, thermal management frameworks and scheduler in Linux kernel. The team also works on testing infrastructure and tools required to evaluate and optimize performance and power consumption of the SoCs. On need basis, the members get involved in other parts of the software stack to accomplish to optimize power and performance.

Some of the key areas where Linaro Power Management team Engineers are currently involved in Linux Kernel are: -

Energy Aware Scheduler (EAS)

  • EAS aims to make power-performance control more centralized in Linux Kernel with the scheduler being the primary driver for power-performance decisions.

Thermal Management

Power Management Frameworks

  • Runtime PM

    GenPD (Generic Power Domain)

    CPU Freq

    CPU Idle

Other initiatives by this team includes

  • DynamIQ Development

    Power management Farm
