EuroBSDCon 2008 - Constantine Murenin - OpenBSD Hardware Sensors Framework
In this talk, we will discuss the past and present history and the design principles of the OpenBSD hardware sensors framework. Sensors framework provides a unified interface for storing, registering and accessing information about hardware monitoring sensors. Sensor types include, but are not limited to, temperature, voltage, fan RPM, time offset and logical drive status. The framework spans sensor_attach(9), sysctl(3), sysctl(8), sensorsd(8), ntpd(8), snmpd(8) and more than 67 drivers, ranging from I2C temperature sensors and Super I/O hardware monitors to IPMI, RAID and SCSI enclosures. Several third-party tools are also available, for example, a plug-in for Nagios and ports/sysutils/symon. Originally based on some ideas from NetBSD, the framework has sustained many improvements in OpenBSD, and was ported and committed to FreeBSD and DragonFly BSD. Constantine A. Murenin is an MMath graduate student at the David R. Cheriton School of Computer Science at the University of Waterloo (CA). Prior to his graduate appointment, Constantine attended and subsequently graduated from East Carolina University (US) and De Montfort University (UK), receiving two bachelor degrees in computer science, with honors and honours respectively. A FreeBSD Google Summer of Code 2007 Student, OpenBSD Committer and Mozilla Contributor, Constantine's interests range from standards compliance and usability at all levels, to quiet computing and hardware monitoring. http://Constantine.SU/

Constantine A. Murenin - Quiet Computing with BSD
Quiet Computing with BSD Programming system hardware monitors for quiet computing In this talk, we will present a detailed 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. 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 and avoid system failure or shutdown during temperature fluctuations, as well as some basic principles regarding quiet computing. Shortly before the talk, a patch for programming the most popular chips (like those from Winbond) will be released for the OpenBSD operating system, although the talk itself will be more specific to the microprocessor system hardware monitors themselves, as opposed to the interfacing with thereof in modern operating systems like OpenBSD, NetBSD, DragonFly BSD and FreeBSD.
