It is builds on the basic 207ebd8b66SMauro Carvalho Chehabfunctionality of the BMC Theseus and contains several new features and 217ebd8b66SMauro Carvalho Chehabenhancements. It can monitor up to 4 voltages, 16 temperatures and 227ebd8b66SMauro Carvalho Chehab8 fans. It also contains an integrated watchdog which is currently 237ebd8b66SMauro Carvalho Chehabimplemented in this driver. 247ebd8b66SMauro Carvalho Chehab 251c5759d8SArmin WolfThe ``pwmX_auto_channels_temp`` attributes show which temperature sensor 261c5759d8SArmin Wolfis currently driving which fan channel. This value might dynamically change 271c5759d8SArmin Wolfduring runtime depending on the temperature sensor selected by 281c5759d8SArmin Wolfthe fan control circuit. 291c5759d8SArmin Wolf 30ca8fd8c1SArmin WolfThe 4 voltages require a board-specific multiplier, since the BMC can 31ca8fd8c1SArmin Wolfonly measure voltages up to 3.3V and thus relies on voltage dividers. 32ca8fd8c1SArmin WolfConsult your motherboard manual for details. 33ca8fd8c1SArmin Wolf 347ebd8b66SMauro Carvalho ChehabTo clear a temperature or fan alarm, execute the following command with the 357ebd8b66SMauro Carvalho Chehabcorrect path to the alarm file:: 367ebd8b66SMauro Carvalho Chehab 377ebd8b66SMauro Carvalho Chehab echo 0 >XXXX_alarm 387ebd8b66SMauro Carvalho Chehab 39*37ef30fbSArmin WolfSpecifications of the chip can be found at the `Kontron FTP Server <http://ftp.kontron.com/>`_ (username = "anonymous", no password required) 40*37ef30fbSArmin Wolfunder the following path: 417ebd8b66SMauro Carvalho Chehab 42*37ef30fbSArmin Wolf /Services/Software_Tools/Linux_SystemMonitoring_Watchdog_GPIO/BMC-Teutates_Specification_V1.21.pdf 43
