Kernel driver gsc-hwmon
|
|
=======================
|
|
|
|
Supported chips: Gateworks GSC
|
|
Datasheet: http://trac.gateworks.com/wiki/gsc
|
|
Author: Tim Harvey <tharvey@gateworks.com>

|
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 Celsius:
|
|
|
|
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 scaled depending on 6 temperature boundaries.
|
|
The tempeature boundaries are read-write and in millidegree Celsius 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.
