You'll need to start powerd, since that is where the sysmon_envsys 
events get delivered.

You'll also need to set sensor thresholds.  The driver uses some built-
values (see the dmesg for details).  It appears that the driver sets the 
FMONCRITOVER flags when appropriate, so if you readch the limit it will 
deliver an event to powerd.  You can also set your own limits to over-
ride the predefined ones, using envstat.

Here's an example that I've used for some testing on one of my machines:

amdtemp0 {
        sensor0 {
                critical-min = 10C;
                warning-min  = 15C;
                warning-max  = 50C;
                critical-max = 55C;
        }
}

They're in the dmesg output as far as I can tell.
