Since I nuked the old adt7467c driver, I might as well nuke the man page.

.Sh DESCRIPTION
|
|
||||||
The
|
|
||||||
.Nm
|
|
||||||
driver provides support for the
|
|
||||||
.Tn Analog Devices
|
|
||||||
ADT7467 and ADM1030 hardware monitor chips to be used with the
|
|
||||||
.Xr envsys 4
|
|
||||||
API.
|
|
||||||
.Pp
|
|
||||||
The ADT7467 supports five sensors:
|
|
||||||
.Bl -column "Sensor" "Units" "Typical" -offset indent
|
|
||||||
.It Sy "Sensor" Ta Sy "Units" Ta Sy "Typical Use"
|
|
||||||
.It Li "temp0" Ta "uK" Ta "chip temperature"
|
|
||||||
.It Li "temp1" Ta "uK" Ta "CPU temperature"
|
|
||||||
.It Li "temp2" Ta "uK" Ta "GPU temperature"
|
|
||||||
.It Li "voltage0" Ta "uV DC" Ta "CPU Vcore"
|
|
||||||
.It Li "fan0" Ta "RPM" Ta "Chassis Fan"
|
|
||||||
.El
|
|
||||||
.Pp
|
|
||||||
The ADM1030 supports three sensors:
|
|
||||||
.Bl -column "Sensor" "Units" "Typical" -offset indent
|
|
||||||
.It Sy "Sensor" Ta Sy "Units" Ta Sy "Typical Use"
|
|
||||||
.It Li "temp0" Ta "uK" Ta "chip temperature"
|
|
||||||
.It Li "temp1" Ta "uK" Ta "CPU temperature"
|
|
||||||
.It Li "fan0" Ta "RPM" Ta "Chassis Fan"
|
|
||||||
.El
|
|
||||||
.Pp
|
|
||||||
Due to hardware limitations, fresh sensor data is only available
|
|
||||||
every 2 seconds.
|
|
||||||
.Pp
|
|
||||||
Both controllers support fan speed control based on temperature
|
|
||||||
thresholds - the fan will spin up when any thermal sensor reaches
|
|
||||||
its configured threshold, it will go faster with higher temperature
|
|
||||||
and slow down when temperature sinks.
|
|
||||||
The fan will be turned off when the sensor(s) that triggered it
|
|
||||||
report a temperature about 5C below threshold.
|
|
||||||
All thresholds are configurable via sysctl:
|
|
||||||
.Bd -literal -offset indent
|
|
||||||
machdep.adt7467c0.temp0 = 56
|
|
||||||
machdep.adt7467c0.temp1 = 85
|
|
||||||
machdep.adt7467c0.temp2 = 76
|
|
||||||
.Ed
|
|
||||||
.Pp
|
|
||||||
Every threshold corresponds to a temperature sensor, so with the
|
|
||||||
ADM1030 there will be only two of them.
|
|
||||||
Both chips use degree Celsius to specify temperature thresholds so
|
|
||||||
that's what the sysctl interface uses too.
|
|
||||||
Configuring a threshold below room temperature will essentially
|
|
||||||
turn on the fan permanently, values above 85C will be rejected.
|
|
||||||
.Sh HISTORY
|
|
||||||
The
|
|
||||||
.Nm
|
|
||||||
device appeared in
|
|
||||||
.Nx 4.0 .
|
|
||||||
.Sh BUGS
|
|
||||||
The drivers have been tested with iBooks only so far.
|
|
||||||
The ADT7467 supports more fan speed sensors but these are unused
|
|
||||||
in iBooks.
