36 ASUS mainboards publish hardware monitoring information via Super I/O
37 chip and the ACPI embedded controller (EC) registers. Some of the sensors
38 are only available via the EC.
40 The driver is aware of and reads the following sensors:
42 1. Chipset (PCH) temperature
43 2. CPU package temperature
44 3. Motherboard temperature
45 4. Readings from the T_Sensor header
48 7. VRM heatsink fan RPM
50 9. Readings from the "Water flow meter" header (RPM)
51 10. Readings from the "Water In" and "Water Out" temperature headers
55 Sensor values are read from EC registers, and to avoid race with the board
56 firmware the driver acquires ACPI mutex, the one used by the WMI when its
57 methods access the EC.
62 The driver holds path to the ACPI mutex for each board (actually,
63 the path is mostly identical for them). If ASUS changes this path
64 in a future BIOS update, this parameter can be used to override
65 the stored in the driver value until it gets updated.
66 A special string ":GLOBAL_LOCK" can be passed to use the ACPI
67 global lock instead of a dedicated mutex.
