Description: |
|
------------ |
|
ASUS mainboards publish hardware monitoring information via Super I/O |
|
chip and the ACPI embedded controller (EC) registers. 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.
