.Nd "ASUSTeK AI Booster ACPI ATK0110 voltage, temperature and fan sensor"
|
||||
.Sh SYNOPSIS
|
||||
To compile this driver into the kernel,
|
||||
place the following lines in your
|
||||
kernel configuration file:
|
||||
.Bd -ragged -offset indent
|
||||
.Cd "device acpi"
|
||||
.Cd "device aibs"
|
||||
.Ed
|
||||
.Pp
|
||||
Alternatively, to load the driver as a
|
||||
module at boot time, place the following lines in
|
||||
.Xr loader.conf 5 :
|
||||
.Bd -literal -offset indent
|
||||
acpi_load="YES"
|
||||
aibs_load="YES"
|
||||
.Ed
|
||||
.Sh DESCRIPTION
|
||||
The
|
||||
.Nm
|
||||
driver provides support for the voltage, temperature and fan sensors
|
||||
available through the
|
||||
.Tn ATK0110
|
||||
.Tn ASOC
|
||||
.Tn ACPI
|
||||
device
|
||||
on
|
||||
.Tn ASUSTeK
|
||||
motherboards.
|
||||
The number of sensors of each type,
|
||||
as well as the description of each sensor,
|
||||
varies according to the motherboard.
|
||||
.Pp
|
||||
The driver supports an arbitrary set of sensors,
|
||||
provides descriptions regarding what each sensor is used for,
|
||||
and reports the current values as well as
|
||||
the supposed range specifications of each sensor's input
|
||||
as defined by the motherboard manufacturer through
|
||||
.Tn ACPI .
|
||||
.Pp
|
||||
The range specifications are as follows:
|
||||
.Bl -bullet
|
||||
.It
|
||||
Voltage sensors have a lower and an upper range specification.
|
||||
.It
|
||||
Temperature sensors have two upper specifications.
|
||||
.It
|
||||
Fan sensors may either have only the lower specification,
|
||||
or, depending on the
|
||||
.Tn DSDT ,
|
||||
one lower and one upper specification.
|
||||
.El
|
||||
.Pp
|
||||
Sensor readings and the range specifications are made available through the
|
||||
.Xr sysctl 3
|
||||
interface,
|
||||
and can be monitored with
|
||||
.Xr sysctl 8 .
|
||||
For example, on an ASUS V3-P5G965 barebone:
|
||||
.Bd -literal -offset indent
|
||||
> sysctl dev.aibs.0.{volt,temp,fan}
|
||||
dev.aibs.0.volt.0: 1192 850 1600
|
||||
dev.aibs.0.volt.1: 3312 2970 3630
|
||||
dev.aibs.0.volt.2: 5017 4500 5500
|
||||
dev.aibs.0.volt.3: 12302 10200 13800
|
||||
dev.aibs.0.temp.0: 28.0C 80.0C 95.0C
|
||||
dev.aibs.0.temp.1: 55.0C 60.0C 95.0C
|
||||
dev.aibs.0.fan.0: 878 600 7200
|
||||
dev.aibs.0.fan.1: 0 700 7200
|
||||
.Pp
|
||||
> sysctl -d dev.aibs.0.{volt,temp,fan}
|
||||
dev.aibs.0.volt:
|
||||
dev.aibs.0.volt.0: Vcore Voltage
|
||||
dev.aibs.0.volt.1: +3.3 Voltage
|
||||
dev.aibs.0.volt.2: +5 Voltage
|
||||
dev.aibs.0.volt.3: +12 Voltage
|
||||
dev.aibs.0.temp:
|
||||
dev.aibs.0.temp.0: CPU Temperature
|
||||
dev.aibs.0.temp.1: MB Temperature
|
||||
dev.aibs.0.fan:
|
||||
dev.aibs.0.fan.0: CPU FAN Speed
|
||||
dev.aibs.0.fan.1: CHASSIS FAN Speed
|
||||
.Ed
|
||||
.Pp
|
||||
Generally, sensors provided by the
|
||||
.Nm
|
||||
driver may also be supported by certain other drivers or utilities
|
||||
that access the
|
||||
.Tn ISA /
|
||||
.Tn LPC
|
||||
or
|
||||
.Tn I2C /
|
||||
.Tn SMBus
|
||||
devices directly.
|
||||
The precise collection of
|
||||
.Nm
|
||||
sensors is comprised of the sensors
|
||||
specifically utilised in the motherboard
|
||||
design, which may be supported through
|
||||
a combination of one or more physical hardware monitoring chips.
|
||||
.Pp
|
||||
The
|
||||
.Nm
|
||||
driver, however, provides the following advantages
|
||||
when compared to the native hardware monitoring drivers or other utilities:
|
||||
.Bl -bullet
|
||||
.It
|
||||
Sensor values from
|
||||
.Nm
|
||||
are expected to be more reliable.
|
||||
For example, voltage sensors in many hardware monitoring chips
|
||||
can only sense voltage from 0 to 2 or 4 volts, and the excessive
|
||||
voltage is removed by the resistors, which may vary with the motherboard
|
||||
and with the voltage that is being sensed.
|
||||
In
|
||||
.Nm ,
|
||||
the required resistor factors are provided by
|
||||
the motherboard manufacturer through
|
||||
.Tn ACPI ;
|
||||
in the native drivers, the resistor factors
|
||||
are encoded into the driver based on the chip manufacturer's recommendations.
|
||||
In essence, sensor values from
|
||||
.Nm
|
||||
are very likely to be identical to the readings from the
|
||||
Hardware Monitor screen in the BIOS.
|
||||
.It
|
||||
Sensor descriptions from
|
||||
.Nm
|
||||
are more likely to match the markings on the motherboard.
|
||||
.It
|
||||
Sensor range specifications are supported by
|
||||
.Nm .
|
||||
The range specification is reported
|
||||
for each individual sensor as suggested by the motherboard manufacturer.
|
||||
For example, the threshold for the CPU temperature sensor is likely
|
||||
to be significantly higher than that for the chassis temperature sensor.
|
||||
.It
|
||||
Support for newer chips in
|
||||
.Nm .
|
||||
Newer chips may miss a native driver,
|
||||
but should be supported through
|
||||
.Nm
|
||||
regardless.
