Description

The BMC Teutates is the Eleventh generation of Superior System monitoring and thermal management solution. It is builds on the basic functionality of the BMC Theseus and contains several new features and enhancements. It can monitor up to 4 voltages, 16 temperatures and 8 fans. It also contains an integrated watchdog which is currently implemented in this driver.

The pwmX_auto_channels_temp attributes show which temperature sensor is currently driving which fan channel. This value might dynamically change during runtime depending on the temperature sensor selected by the fan control circuit.

The 4 voltages require a board-specific multiplier, since the BMC can only measure voltages up to 3.3V and thus relies on voltage dividers. Consult your motherboard manual for details.

To clear a temperature or fan alarm, execute the following command with the correct path to the alarm file:

echo 0 >XXXX_alarm
