HISTORY
The upd driver first appeared in OpenBSD 5.6.

The upd driver was written by Andre de Oliveira.
BUGS
The upd driver does not indicate device health via aggregate or
individual sensor status. Users who wish to monitor upd status using
sensorsd(8) must manually establish "high" and "low" limits for sensor
values of interest via sensorsd.conf(5).
