http://perforce.freebsd.org/chv.cgi?CH=125385 Change 125385 by cnst@dale on 2007/08/20 03:50:39 add a caveats section documenting sensor_task differences in OpenBSD 4.2, sensor_task was converted to use use OpenBSD's workq_add_task(9), which is not available on FreeBSD. In cnst-sensors, I have so far ported the older version of sensor_task as all of the necessary functions that it uses are here on FreeBSD. It is questionable whether sensor_task in soc2007/cnst-sensors should be compatible with 4.2, because it will involve additional code that is, at this point, noone except for me is testing. So for now, I think it is a much wiser choice to stick with sensor_task that is compatible with 4.1, and then when I'll have some testers, write an entirely new sensor_task if that will be deemed necessary. P.S. Converting the drivers from old sensor_task to new sensor_task (and back) is as easy as 123. :) In any case, any help or hints with sensor_task is appreciated. The current implementation for FreeBSD is long as available in the p4 repository, in soc2007/cnst-sensors/sys.kern/kern_sensors.c.
