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