hi, tiejun.chen: Thanks for replying. I tried to use ioremap too, but it doesn't work. The ioport_map method succeeded under mpc8641d which is also a ppc. In fact, I also tried using pci_iomap by imitating rtl8139's codes. The rtl8139's BAR0 is also a I/O mapped register and its code succeeded in accessing its registers by using pci_iomap under sbc8548. But when I used pci_iomap for my PCIe card, its output is just the same with the method of using ioport_map. Any suggestion?
