Module Parameters |
|
----------------- |
|
|
|
* reset boolean |
|
(default 0) |
|
|
|
Use 'reset=1' to reset the chip (via index 0x40, bit 7). The default |
|
behavior is no chip reset to preserve BIOS settings |

Description |
|
----------- |
|
|
|
This driver implements support for Winbond W83L786NG/W83L786NR chips. |
|
|
|
The driver implements two temperature sensors, two fan rotation speed |
|
sensors, and three voltage sensors. |
|
|
|
Temperatures are measured in degrees Celsius and measurement resolution is 1 |
|
degC for temp1 and temp2. |
|
|
|
Fan rotation speeds are reported in RPM (rotations per minute). Fan readings |
|
can be divided by a programmable divider (1, 2, 4, 8, 16, 32, 64 |
|
or 128 for fan 1/2) to give the readings more range or accuracy. |
|
|
|
Voltage sensors (also known as IN sensors) report their values in millivolts. |
|
An alarm is triggered if the voltage has crossed a programmable minimum |
|
or maximum limit. |
