Description¶

The BMC Teutates is the Eleventh generation of Superior Systemmonitoring and thermal management solution. It is builds on the basicfunctionality of the BMC Theseus and contains several new features andenhancements. It can monitor up to 4 voltages, 16 temperatures and8 fans. It also contains an integrated watchdog which is currentlyimplemented in this driver.

ThepwmX_auto_channels_temp attributes show which temperature sensoris currently driving which fan channel. This value might dynamically changeduring runtime depending on the temperature sensor selected bythe fan control circuit.

The 4 voltages require a board-specific multiplier, since the BMC canonly 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 thecorrect path to the alarm file:

echo 0 >XXXX_alarm
