Readings from the "Water flow meter" header (RPM) +10. Readings from the "Water In" and "Water Out" temperature headers +11. CPU current + +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. diff --git a/Documentation/hwmon/index.rst b/Documentation/hwmon/index.rst index df20022c741f..b69fdaf1af82 100644 --- a/Documentation/hwmon/index.rst +++ b/Documentation/hwmon/index.rst @@ -43,6 +43,7 @@ Hardware Monitoring Kernel Drivers asb100 asc7621 aspeed-pwm-tacho + asus_ec_sensors asus_wmi_ec_sensors asus_wmi_sensors bcm54140 |
