Abstract:

Quiet Computing with BSD
(Programming system hardware monitors for quiet computing)

In this talk, we will present an overview of the features and common problems of microprocessor system hardware monitors as they relate to the topic of silent computing. In a nutshell, the topic of programmable fan control will be explored. A live demonstration of the fan-controlling prototype might be possible.

Silent computing is an important subject as its practice reduces the amount of unnecessary stress and improves the motivation of the workforce, at home and in the office.

Attendees will gain knowledge on how to effectively programme the chips to minimise fan noise without impeding reliability or causing any system failures, as well as some basic principles regarding the practice of quiet computing.

A patch for programming the most popular chips (like those from Winbond) is already publicly available for the OpenBSD operating system, although the talk itself will be more specific to the microprocessor system hardware monitors themselves, as opposed to any specific interfacing with thereof in modern operating systems like OpenBSD, NetBSD, DragonFly BSD and FreeBSD. (Depending on the availability of the author, patches for systems other than OpenBSD may also be made available.)
