Rootconf is India's principal conference where systems and operations engineers share real world knowledge about building resilient and scalable systems.

A software view at power management

Submitted by peter de schrijver (@p2) on Dec 21, 2015

Section: Full talk Technical level: Advanced Status: Submitted


Learn the commonly used software techniques for controlling power consumption in computers.


The talk will explain the software techniques commonly used in OSes to control power consumption. Background on why these techniques work will be provided as well as the configuration knobs to control them.


computer architecture basics.
basic knowledge about operating system internals (what’s the scheduler, what’s an interrupt)

Speaker bio

Peter is an old time linux user and kernel hacker. He has developed a wide variety of drivers for the linux kernel (network, USB, i2c, spi, clocks, audio).

    I think this would be a good talk. I would like to learn more about how conflicts of interests between “power management” and “performance” can lead to failures on both fronts: more power consumption and poorer performance.

    It would be enlightening to learn how application developers and operations engineers could work /with/ their operating systems, rather than /against/ them, to balance power management and performance concerns.
