They can monitor up to 5 voltages, 4 fans and 8 temperatures. + +In addition, the SCH5627 exports data describing which temperature sensors +affect the speed of each fan. Setting pwmX_auto_channels_temp to 0 forces +the corresponding fan to full speed until another value is written. + +The SMSC SCH5627 hardware monitoring part also contains an integrated +watchdog. In order for this watchdog to function some motherboard specific +initialization most be done by the BIOS, so if the watchdog is not enabled +by the BIOS the sch5627 driver will not register a watchdog device. + +The hardware monitoring part of the SMSC SCH5627 is accessed by talking +through an embedded microcontroller. An application note describing the +protocol for communicating with the microcontroller is available upon +request. Please mail me if you want a copy. -- cgit v1.2.3
