Currently only supports AMD boards from the One X Player lineup. Intel boards could be supported if we could figure out the EC registers and values to write to since the EC layout and model is different. Sysfs entries ------------- The following attributes are supported: fan1_input Read Only. Reads current fan RMP. pwm1_enable Read Write. Enable manual fan control. Write "1" to set to manual, write "0" to let the EC control de fan speed. Read this attribute to see current status. pwm1 Read Write. Read this attribute to see current duty cycle in the range [0-255]. When pwm1_enable is set to "1" (manual) write any value in the range [0-255] to set fan speed.
