| 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. |
| |
| 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. VRM heatsink fan RPM |
| 8. Chipset fan RPM |
| 9. Readings from the "Water flow meter" header (RPM) |
| 10. Readings from the "Water In" and "Water Out" temperature headers |
| 11. CPU current |
| 12. CPU core voltage |
| |
| Sensor values are read from EC registers, and to avoid race with the board |
| firmware the driver acquires ACPI mutex, the one used by the WMI when its |
| methods access the EC. |
| |
| Module Parameters |
| ----------------- |
| * mutex_path: string |
| The driver holds path to the ACPI mutex for each board (actually, |
| the path is mostly identical for them). If ASUS changes this path |
| in a future BIOS update, this parameter can be used to override |
| the stored in the driver value until it gets updated. |
