val = pci_read_config(dev, OFFSET, len); dev: the PCI device your driver is working on OFFSET: the position you want to read from len: the number of bytes you want to read Because you specify the pci dev the system knows where to read from. Look at any random pci driver in sys/ and it will all become clear.
