I am planning to interfacing the PCI bus using L4, however, I do not quite know how PCI interface works. I know that there is three memory region: configuration space, I/O space and Memory space, and that configuration space is use to detect and configure the device, but I do not know where any of this space are located and the protocol for interfacing them. Please help.
