The purists won out in that one by shouting loudly and screaming about socialized healthware. Consequently we have 47 million unsupported devices.

In OpenBSD they have project sponsored healthware and sometimes you have to wait in a queue to get you notifications, and sometimes the queue is so long events have to get merged! Not for me!
I want all my individual events to be lost After I get them.
It's my right!

		Google Summer of Code 2007 @ The FreeBSD Project
	Porting OpenBSD's sysctl Hardware Sensors framework to FreeBSD
			(2007-256, a 23-y.-o. edition)


Description:

	On this 256th day of 2007,   it is my great pleasure to
	present a feature-complete port of the hardware sensors
	framework from OpenBSD to FreeBSD.

	Below is a complete `cvs diff` of cnst-sensors GSoC2007
	project as of 2007-256.

	It includes the following components,  listed below in
	the very same order as they are appearing in this diff:

	* sample configuration file for sensorsd
	* rc(8) script and glue code for sensorsd(8)
	* sysctl(3) doc fixes for CTL_HW tree
	* sysctl(3) documentation for hardware sensors
	* sysctl(8) documentation for hardware sensors
	* assorted KNF and bug-fixes for sysctl(8)
	* support for the sensor structure for sysctl(8)
	* coretemp(4) documentation
	* it(4) documentation
	* lm(4) documentation
	* rc.conf(5) documentation for starting sensorsd(8)
	* sensor_attach(9) et al documentation
	* coretemp(4) conversion to the hw.sensors framework
	* it(4) isa driver ported from OpenBSD
	* lm(4) isa driver ported from OpenBSD
	* /sys/kern/kern_sensors.c
	  o sensor_attach(9) API for drivers to register ksensors
	  o sensor_task_register(9) API for the update task
	  o sysctl(3) glue code
	  o hw.sensors shadow tree for sysctl(8) internal magic
	* assorted KNF and bug-fixes for /sys/kern/kern_sysctl.c
	* it(4) module for testing sensor_attach/detach et al
	* lm(4) module for testing sensor_attach/detach et al
	* <sys/sensors.h>
	* assorted bug-fixes and HW_SENSORS definition for <sys/sysctl.h>
	* sensors display for systat(1), including all documentation
	* sensorsd(8) and all applicable documentation

	The userland part of the framework is entirely source-code
	compatible with OpenBSD 4.1, 4.2 and  -current as of today.

	All sensor readings can be viewed with `sysctl hw.sensors`,
	monitored in semi-realtime with `systat -sensors` and also
	logged with `sensorsd`.   Third-party tools, for example a
	plug-in for nagios, are also available.  A separate patch
	for ports/sysutils/symon will be provided upon request.

Exact directions on applying and testing:

23:08 < constant> just got back from a Western Union
23:08 < constant> received a whole pocket load of bills for my initial payment. :)
23:10 < constant> 14 bills in total! :)
23:10 < constant> at least, they didn't give me any coins. :)))
23:10 <@jbr> nice :)
23:10 <@jbr> i only got 3 bills and some coins :(
