通过对此域的写可以控制此设备,如允许设备访问PCI I/O内存。 分类代码(Class Code) 此域标识本设备的类型。对于每种类型的视频,SCSI等设备都有标准的分类代码。如SCSI设备分类代码为0x0100。 基地址寄存器(Base Address Registers) 这些寄存器用来决定和分配此设备可以使用的PCI I/O与PCI内存空间的类型,数量及位置。
pci_enable_device(dev);pci_request_regions(dev,"expdev");bar1=pci_iomap(dev,1,0);// void iowrite32(u32 val, void __iomem *addr)iowrite32(0xaaaaaaaa,bar1+0x060000);/* offset from device spec */ 但到了最后,这个设备并没有像预期的那样完成他的工作。然后我查看了bar1后面的地址,发现...
