NAME

aibsASUSTeK AI Booster ACPI ATK0110 temperature, voltage, and fan sensor

SYNOPSIS

aibs* at acpi?

DESCRIPTION

The aibs driver provides support for the voltage, temperature and fan sensors available through the ATK0110 ACPI device on ASUSTeK motherboards. The number of sensors of each type, as well as the description of each sensor, varies according to the motherboard.
The driver supports an arbitrary set of sensors, provides a description regarding what each sensor is used for, and reports whether each sensor is within the specifications as defined by the motherboard manufacturer through ACPI.
The aibs driver supports sensor states as follows: temperature sensors can have a state of OK, WARN, CRIT or UNKNOWN; fan and voltage sensors can have a state of OK or WARN only. Temperature sensors that have a reading of 0 are marked as invalid and their state is set to UNKNOWN, whereas all other sensors are always assumed valid. Temperature sensors have two upper limits (WARN and CRIT), fan sensors have either only the lower limit, or one lower and one upper limit, and voltage sensors always have a lower and an upper limit.
Sensor values are made available through the HW_SENSORS sysctl(2) interface, and can be monitored with the systat(1) sensors view, sensorsd(8), or sysctl(8) hw.sensors. For example, on an Asus Stricker Extreme motherboard:
$ sysctl hw.sensors.aibs0 
hw.sensors.aibs0.temp0=31.00 degC (CPU Temperature), OK 
hw.sensors.aibs0.temp1=43.00 degC (MB Temperature), OK 
hw.sensors.aibs0.fan0=2490 RPM (CPU FAN Speed), OK 
hw.sensors.aibs0.fan1=0 RPM (CHASSIS FAN Speed), WARNING 
hw.sensors.aibs0.fan2=0 RPM (OPT1 FAN Speed), WARNING 
hw.sensors.aibs0.fan3=0 RPM (OPT2 FAN Speed), WARNING 
hw.sensors.aibs0.fan4=0 RPM (OPT3 FAN Speed), WARNING 
hw.sensors.aibs0.fan5=0 RPM (OPT4 FAN Speed), WARNING 
hw.sensors.aibs0.fan6=0 RPM (OPT5 FAN Speed), WARNING 
hw.sensors.aibs0.fan7=0 RPM (PWR FAN Speed), WARNING 
hw.sensors.aibs0.volt0=1.26 VDC (Vcore Voltage), OK 
hw.sensors.aibs0.volt1=3.25 VDC ( +3.3 Voltage), OK 
hw.sensors.aibs0.volt2=4.95 VDC ( +5.0 Voltage), OK 
hw.sensors.aibs0.volt3=11.78 VDC (+12.0 Voltage), OK 
hw.sensors.aibs0.volt4=1.23 VDC (1.2VHT Voltage), OK 
hw.sensors.aibs0.volt5=1.50 VDC (SB CORE Voltage), OK 
hw.sensors.aibs0.volt6=1.25 VDC (CPU VTT Voltage), OK 
hw.sensors.aibs0.volt7=0.93 VDC (DDR2 TERM Voltage), OK 
hw.sensors.aibs0.volt8=1.23 VDC (NB CORE Voltage), OK 
hw.sensors.aibs0.volt9=1.87 VDC (MEMORY Voltage), OK
Generally, sensors provided by the aibs driver may also be supported by a variety of other drivers, such as lm(4) or it(4). The precise collection of aibs 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.
The aibs driver, however, provides the following advantages when compared to the native hardware monitoring drivers:
As a result, sensor readings from the actual native hardware monitoring drivers may be ignored as appropriate.
