dm9000网卡移植咨询

Question

我用linux-2.6.22.2内核  移植了网卡驱动 显示如下信息， 帮我看下我的网卡驱动移植成功没有？

如果成功了为什么我无法NFS，  是不是MAC地址未修改的原因？

Answer 1

移植后首先检查一下，能不能ping出去包吧

Answer 2

呵呵，这两天正好在看dm9000A的驱动呢。你lsmod一下，看看模块是否加载。然后dmesg看一下有没有dm9000的输出信息。厂商提供的驱动里面是找到设备时是有打印信息的。然后就是具体功能的测试了。

Answer 4

请教个问题，PID和VID识别不对，一般问题会出现在哪里？下面代码是PID和VID识别的部分，正确值应该是90000a46，我这里打印出来的值确是10000ac6。
        outb(DM9000_VID_L, iobase);
        id_val = inb(iobase + 4);
        outb(DM9000_VID_H, iobase);
        id_val |= inb(iobase + 4) << 8;
        outb(DM9000_PID_L, iobase);
        id_val |= inb(iobase + 4) << 16;
        outb(DM9000_PID_H, iobase);
        id_val |= inb(iobase + 4) << 24;
        printk("<0>......id_val is %x......\n",id_val);
        if (id_val == DM9000_ID) {
            printk("DM9000A ethernet driver V1.26 I/O: %x, VID: %x \n",
                    iobase, id_val);

PID和VID无法正确识别，内核驱动加载不上去，请大家提提建议，谢谢啦

恩，PID和VID应该是0x90000a46. 这个网卡你自己没有做过什么修改吧。这个value本身是存在他自己的寄存器的。怎么会不对呢？

对了，源码是只执行多次探测的，有个do-while循环。你这个结果应该是其中一次的吧。所有结果都没有匹配上这个ID吗。

另外，ID是0x90100a46，应该也是DM9000网卡。

驱动加入到内核，每次启动只有一次显示id值，没进入到循环
初步怀疑是硬件的问题

不考虑系统启动的时候，当你系统上有DM9000A的网卡，然后你insmod的时候，程序内核会进行probe，探测这个网卡的ID是都正确。探测的过程可以看一下源码，里面是要执行多次（好像是7次）循环，直到探测到符合DM9000A的网卡的设备。否则，insmod的时候就会报错的。

可以这样试一下。

Answer 9

我在本机上测试

[root@localhost dm9ks_20080214]# insmod dm9ks.ko
insmod: error inserting 'dm9ks.ko': -1 No such device
[root@localhost dm9ks_20080214]#

由于我本机上没有DM9000A网卡，所以就直接报错： No such device。
