LinuxCon Japan is the premiere Linux conference in Asia that brings together a unique blend of core developers, administrators, users, community managers and industry experts.
CloudOpen Japan is a conference celebrating and exploring the open source projects, technologies and companies who make up the cloud. It’s built on a belief that open works: for users, for industry and for technology.
In upstream, Linux kernel support is going on for ARM new big.LITTLE architecture. On the other hand, we already has some existing support in Linux kernel such as cgroups, hotplug etc. Chris Redpath from ARM proposed this user space approach in his pioneering work based on simulation environment. We took a further step and integrated a new prototype implementation into Android environment on our APE6 LSI which is one of the first SoCs supporting big.LITTLE architecture. And got some insight and found some issues to be solved.
To all audience who has interest in big.LITTLE MP system. We can share our experimental results and experience on real silicon supporting big.LITTLE MP hardware with community members to further investigate better solutions.
