In stark contrast with decades past, thermal issues in computer systems now means much more than fans and heat sinks, and this microconference looks at some of the things that are now handled in software. The topics include the thermal framework, handling of temperature sensors, and different approaches to handling overtemperature conditions, ranging up to and including closed-loop control. Of course, software that is not tested can be assumed not to work, and the best way to ensure that testing happens when needed is to automate it, so automated testing of thermal subsystems is also on the agenda. Coordination with userspace is useful in order to determine how best to shed computational load, as is coordination among multiple cooling devices.
