LinuxCon Japan 2011 | Presentations

Runtime PM (BoFs)

Date: Thursday, June 3rd
Time: 11:00am
Location: Room 501

Runtime PM is becoming increasingly important for efficient power management of I/O devices on embedded systems. This BoF is a chance to discuss a wide range of power management topics centered around the Runtime PM framework. Some of the topics discussed may include device driver use cases, QoS requirements, SoC-specific hooks, code reuse, CPUIdle integration and how to let Runtime PM coexist together with system wide suspend/resume.

 

Tim Bird, Sony Network Entertainment

In this position, Tim directs the technical initiatives of the forum, and encourages companies to publish their improvements to Linux and participate in the open source community. Tim has been working with Linux for over 19 years.

Hisao Munakata, Renesas

Munakata is an executive manager of Renesas Solutions Corp and lead opensource development initiative in Renesas. As an embedded CPU provider, Renesas delivers Linux BSP to our customer so that they can develop their embedded products like TV, cell-phone and home appliances. At its early stage, maybe a few years ago, we developed relatively old snapshot BSP and keep it maintained for its lifetime without any version migration. This release model worked as interim solution, but now people expect more progressive release, tight collaboration with upstream evolution. So now we have started two separate activities to develop our BSP. One is leading edge upstream development and others are stabilization and integration process. Essentially these two are including controversial motivation, but we have tried to harmonize them to make better asset. I hope this coordination effort can be a good reference to anyone who wants aggressive utilization of open source asset.
