Dear freebsd-current@, It is my pleasure to present a Technology Preview patch that ports most of the base components of OpenBSD's hardware sensors framework to FreeBSD. Apart from the kernel framework for registering and accessing hardware sensors, this patch includes the lm(4) driver that supports nearly all known Winbond Super I/O chips that the majority of PCs have today. It also includes a patch that converts coretemp(4) driver to the new framework. Most noticeably, this patch does not yet include sysctl(8) access to hardware sensors; however, sensor readings can be conveniently monitored with systat(1) sensors display and logged with the included sensorsd(8). (As this project is about porting the framework, no iic(4) drivers were or will be ported from OpenBSD at this time -- however, if you are willing to port some drivers and need help with sensors framework, let me know.) Apply to FreeBSD 7.0-CURRENT as of 2007-08-20 by doing: cd /usr/src fetch http://p4web.freebsd.org/depot/projects/soc2007/cnst-sensors/cnst-sensors.2007-08-20.patch mkdir sys/dev/lm sys/modules/lm usr.sbin/sensorsd patch < cnst-sensors.2007-08-20.patch More details, including some installation instructions, are available in my LJ: http://cnst.livejournal.com/34170.html Cheers, Constantine, Google Summer of Code 2007 Student @ The FreeBSD Project. :) On 20/08/2007 23:39, Constantine A.
