15 | Description | |
16 | ----------- | |
17 | ||
18 | SMSC SCH5636 Super I/O chips include an embedded microcontroller for | |
19 | hardware monitoring solutions, allowing motherboard manufacturers to create | |
20 | their own custom hwmon solution based upon the SCH5636. | |
21 | ||
22 | Currently the sch5636 driver only supports the Fujitsu Theseus SCH5636 based | |
23 | hwmon solution. The sch5636 driver runs a sanity check on loading to ensure | |
24 | it is dealing with a Fujitsu Theseus and not with another custom SCH5636 based | |
25 | hwmon solution. | |
26 | ||
27 | The Fujitsu Theseus can monitor up to 5 voltages, 8 fans and 16 | |
28 | temperatures. Note that the driver detects how many fan headers / | |
29 | temperature sensors are actually implemented on the motherboard, so you will | |
30 | likely see fewer temperature and fan inputs. | |

32 | The Fujitsu Theseus hwmon solution also contains an integrated watchdog. |
33 | This watchdog is fully supported by the sch5636 driver. | |

35 | An application note describing the Theseus' registers, as well as an |
36 | application note describing the protocol for communicating with the | |
37 | microcontroller is available upon request. Please mail me if you want a copy. |
