Regulators: Learning To Play With Others - Mark Brown, Linaro

Sign up or log in to save this to your schedule and see who's attending!

Traditionally embedded Linux systems have been built on the basis that idea that the processor running Linux has full control of the system and can directly manage the hardware at all times. This has never been true for all systems and with modern power sensitive systems very often have coprocessors managing the lowest power states while Linux is suspended or idling CPUs. This especially affects the regulator API which must coordinate with these coprocessors to provide functionality in low power states, this is the main current driving force for development in the API.

This talk will provide an introduction both the the regulator API and current systems, then discuss approaches to extending the regulator API to get the best from these systems.
