Do you know how batteries and battery chargers are handled in the Linux kernel subsystem? While not as complex as the DRM subsystem, the power-supply subsystem is a key part of embedded mobile devices running Linux. This talk will be an quick overview of the subsystem and its latest features, from hardware (e.g. what’s a smart battery), to sysfs and uevent API exposed to userspace.
