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