Abstract

Power Management engineers work hard at quiescing a system. But various hardware and software bits keep waking up the system, sometimes with no good reason. The idle framework works independently in an opportunistic way. How to change it to collaborate with the scheduler in order to get better results ? This presentation will detail some of the common culprits and will present an improvement based on a collaboration between the idle framework and the scheduler.

  Biography

  Preeti U Murthy joined IBM Linux Technology Center in May 2012 as a fresher,after graduating from National Institute of Technology,Surathkal in the same year.Since then she has been working as a kernel developer on Energy Management features in the Linux Kernel such as Suspend-To-Ram and power aware scheduler.She has been working closely with the Linux community to improve the performance and scalability of the linux scheduler and to bring in energy awareness into it in the form of a power aware scheduler. Currently she is working on CPU power management for the Power architecture.
