Hello friends,
I am at present working on writing a device driver in linux for pci bridge that is present in mpc 8266 having a real time favor of linux OS on board. Actually our purpose is to use design a card which have two processors on it and use pci bus to communicate between them. I have some conceptual doubts regards to pci bus.
Q. What is prefectable memory and non-prefetchable memory in case of mpc8266 pci controller? Q. How is access of a pci prefetchable memory different from a non prefetchable memory? Q. Are Machine check interrupts some thing similar to probe signals in device driver context?
please help me out.
