• dm9000c 移值新内核 linux-4.1.24


    错误 1

    /home/dm9000/dm9dev9000c.c:309: error: conflicting types for 'phy_read'
    include/linux/phy.h:637: error: previous definition of 'phy_read' was here
    /home/dm9000/dm9dev9000c.c:310: error: conflicting types for 'phy_write'
    include/linux/phy.h:652: error: previous definition of 'phy_write' was here

    linux/phy.h 也定义了这个函数,所以这里要改名.
    phy_read 改名为 dm9000_phy_read

    错误 2
    dm9dev9000c.c:356: error: implicit declaration of function 'SET_MODULE_OWNER'
    查看 linux2.6.22 源码查看发现只是一个宏定义 #define SET_MODULE_OWNER(dev) do { } while (0)

    错误 3
    /home/dm9000/dm9dev9000c.c:407: error: 'struct net_device' has no member named 'priv'
    /home/dm9000/dm9dev9000c.c:408: error: 'struct net_device' has no member named 'priv'
    /home/dm9000/dm9dev9000c.c:422: error: 'struct net_device' has no member named 'open'
    /home/dm9000/dm9dev9000c.c:423: error: 'struct net_device' has no member named 'hard_start_xmit'

    /* Allocated board information structure */
    memset(dev->priv, 0, sizeof(struct board_info));
    db = (board_info_t *)dev->priv;
    改为
    db = netdev_priv(dev);
    /* Allocated board information structure */
    memset(db, 0, sizeof(struct board_info));

    这里改的比较多,最后见补丁吧
    static const struct net_device_ops dm9000_netdev_ops = {
    .ndo_open = dm9000_open,
    .ndo_stop = dm9000_stop,
    .ndo_start_xmit = dm9000_start_xmit,
    .ndo_tx_timeout = dm9000_timeout,
    .ndo_set_rx_mode = dm9000_hash_table,
    .ndo_do_ioctl = dm9000_ioctl,
    .ndo_change_mtu = eth_change_mtu,
    .ndo_set_features = dm9000_set_features,
    .ndo_validate_addr = eth_validate_addr,
    .ndo_set_mac_address = eth_mac_addr,
    #ifdef CONFIG_NET_POLL_CONTROLLER
    .ndo_poll_controller = dm9000_poll_controller,
    #endif
    };

    需要复制 内核自带的 dm9000.h
