| Description: |
| ------------ |
| ASUS mainboards publish hardware monitoring information via Super I/O |
| chip and the ACPI embedded controller (EC) registers. Some of the sensors |
| are only available via the EC. |
| |
| ASUS WMI interface provides a method (BREC) to read data from EC registers, |
| which is utilized by this driver to publish those sensor readings to the |
| HWMON system. The driver is aware of and reads the following sensors: |
| |
| 1. Chipset (PCH) temperature |
| 2. CPU package temperature |
| 3. Motherboard temperature |
| 4. Readings from the T_Sensor header |
| 5. VRM temperature |
| 6. CPU_Opt fan RPM |
| 7. Chipset fan RPM |
| 8. Readings from the "Water flow meter" header (RPM) |
| 9. Readings from the "Water In" and "Water Out" temperature headers |
| 10. CPU current |
