Kernel driver gsc-hwmon |
|
======================= |
|
|
|
Supported chips: Gateworks GSC |

Description: |
|
------------ |
|
|
|
This driver supports hardware monitoring for the temperature sensor, |
|
various ADC's connected to the GSC, and optional FAN controller available |
|
on some boards. |
|
|
|
|
|
Voltage Monitoring |
|
------------------ |
|
|
|
The voltage inputs are scaled either internally or by the driver depending |
|
on the GSC version and firmware. The values returned by the driver do not need |
|
further scaling. The voltage input labels provide the voltage rail name: |
|
|
|
inX_input Measured voltage (mV). |
|
inX_label Name of voltage rail. |
|
|
|
|
|
Temperature Monitoring |
|
---------------------- |
|
|
|
Temperatures are measured with 12-bit or 10-bit resolution and are scaled |
|
either internally or by the driver depending on the GSC version and firmware. |
|
The values returned by the driver reflect millidegree Celcius: |
|
|
|
tempX_input Measured temperature. |
|
tempX_label Name of temperature input. |
|
|
|
|
|
PWM Output Control |
|
------------------ |
|
|
|
The GSC features 1 PWM output that operates in automatic mode where the |
|
PWM value will be scalled depending on 6 temperature boundaries. |
|
The tempeature boundaries are read-write and in millidegree Celcius and the |
|
read-only PWM values range from 0 (off) to 255 (full speed). |
|
Fan speed will be set to minimum (off) when the temperature sensor reads |
|
less than pwm1_auto_point1_temp and maximum when the temperature sensor |
|
equals or exceeds pwm1_auto_point6_temp. |
|
|
|
pwm1_auto_point[1-6]_pwm PWM value. |
|
pwm1_auto_point[1-6]_temp Temperature boundary. |
