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. + A special string ":GLOBAL_LOCK" can be passed to use the ACPI + global lock instead of a dedicated mutex. |
