Embedded Linux Conference + Android Builders Summit

The past year has seen a remarkable growth of interest in super-low-power and super-low-form-factor computing, in the form of 'wearables', the 'Internet of Things', and the release of exciting new hardware such as Intel's Quark and Edison SoCs. Taking advantage of this super-small hardware also implies the need for super-small operating systems and applications to match. This talk will describe a super-small-footprint Linux distribution called 'microYocto''. The main focus will be the kernel and how we achieved what we think is close to the minimal possible kernel footprint, both in terms of static text size and dynamic memory usage. We'll talk about the tools and methodologies we used and developed to analyze the problem, such as tracing and machine simulation, and will describe the various technologies developed and applied to achieving this minimalistic system.
