Hi, In one of our desktop system, a microcontroller is connected to ICH6 GPIO 18. The microcontroller generates some signal which has to be read and action has to be taken. Could someone help me how to access the ICH6 GPIO on a linux system. Does the linux kernel provide some API's to access the GPIO's on ICH6 or should I have to develop a driver to access this GPIO.
