Communication between components is necessary for effective power management in mobile devices. The System Power Management Interface, also known as SPMI, is a standardized bus interface intended to provide power-management related connectivity between components. Josh Cartwright will provide a high-level architectural overview of SPMI and discuss how to leverage the Linux Kernel software interfaces (expected to land in 3.15) to communicate with devices on the bus.
Josh Cartwright has been a Linux enthusiast since he first installed Slackware on an old machine ten years ago. He's currently a Software Engineer at the Qualcomm Innovation Center out of Austin, TX, where he's part of a team tasked with rounding out upstream Linux Kernel support for the MSM family of SoCs. When he's not hacking on Linux, he likes to homebrew beer.
