Description:¶

This driver supports hardware monitoring for the temperature sensor,various ADC’s connected to the GSC, and optional FAN controller availableon some boards.

Voltage Monitoring¶

The voltage inputs are scaled either internally or by the driver dependingon the GSC version and firmware. The values returned by the driver do not needfurther 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 scaledeither 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 thePWM value will be scalled depending on 6 temperature boundaries.The tempeature boundaries are read-write and in millidegree Celcius and theread-only PWM values range from 0 (off) to 255 (full speed).Fan speed will be set to minimum (off) when the temperature sensor readsless than pwm1_auto_point1_temp and maximum when the temperature sensorequals or exceeds pwm1_auto_point6_temp.

pwm1_auto_point[1-6]_pwm PWM value.pwm1_auto_point[1-6]_temp Temperature boundary.
