.Sh SYNOPSIS
|
|
.Cd "adm1026hm* at iic0 addr 0x2e: ADM1026 hardware monitor: rev. 0x4, step. 0x5"
|
|
.Cd "adm1026hm*: 8 fans, 3 temperatures, 15 voltages"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for the Analog Devices ADM1026 hardware monitor.
|
|
The chip possesses 8 fan speed sensors, 3 temperature sensors,
|
|
and 17 voltage sensors.
|
|
The number of each sensor type configured by the driver depends on the
|
|
chip configuration.
|
|
.Pp
|
|
The values of the sensors are made available through the
|
|
.Xr envstat 8
|
|
interface.

The

|
|
driver was written by

.An Julian Coleman Aq Mt jcoleman@NetBSD.org .
|
|
.Sh BUGS
|
|
It's not possible to determine if either a sensor is not connected,
|
|
or the monitored device is producing no output.
|
|
Therefore, unconnected sensors will show outputs of 0.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver does not support checking or altering limit values, interrupt output,
|
|
nor the built-in EEPROM.
