- Kernel driver sch5627
- =====================
- Supported chips:
- * SMSC SCH5627
- Prefix: 'sch5627'
- Addresses scanned: none, address read from Super I/O config space
- Datasheet: Application Note available upon request
- Author: Hans de Goede <[email protected]>
- Description
- -----------
- SMSC SCH5627 Super I/O chips include complete hardware monitoring
- capabilities. 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.
