【Linux】当前进展

驱动层日志添加了下文件目录，函数，代码行的打印（这里要小心，驱动目录源代码打印日志里边添进程号可能有问题，因为在驱动初始化的时候，内核还没有创建进程，不过猜测可以先不打印进程相关信息，在操作系统完成启动后再打印可能没有问题，不过在前面测试的时候，在驱动目录代码里边添加sched.h会报错，因为这个头文件对其他头文件的依赖本来就非常复杂）：

添加日志文件目录，函数，代码行的打印前是这样的，比如想看某处打印详细代码位置，是很难的：

添加打印信息后是这样的，这样要找源代码目录比较容易，比较容易找到代码执行流程：

这里实际上是很多模块在初始化，calling后边的函数是可以直接在代码里边搜索的，一般都是一个模块的初始化入口：

这里可以看到总线上在不断添加计算机硬件的驱动：

这里好像是在添加osi的：

这里要注意，是在初始化网卡，e1000目录里有网卡初始化代码：

如果是看下边这个图，比较明显可以看出来IP层、UDP层、以太层源代码目录，很方便：

TCP打印日志的代码还比较少：

这样可以跟网络协议层对应上：

网卡驱动（e1000）到77XX行才装，这块没想明白，从下边这个日志也可以看出来不同驱动安装的先后顺序和大概时间

从内核打印日志中可以找到总线挂载的位置，然后找到安装的驱动：

实际在收发以太层数据包也是可以看到的：

驱动层很多源代码采用如下宏打印日志，添加了打印文件，行，函数，不知道能不能把进程id也添加上：

有些驱动目录的源代码不是使用的这个打印宏，修改后的代码

（参考来源：include/linux/printk.h）：

修改的源代码，这里碰到一个问题，这个问题改和测试花了一两天（主要是修改dev_printk.h或printk.h这类头文件修改，基本上要全量编译，涉及需要在头文件的函数中添加打印日志的一定要小心，现在一般看到头文件，手都不怎么敢碰键盘，不小心修改了文件，很耗时间，doge），现在能运行的内核是需要编译两次（也可能理解的不对），第一次编译会报链接错误，再编译一次就好了，而且这样编译的内核还可以启动，这。。。。：

补充：

netdev_start_xmit到e1000_xmit_frame，应该是下边代码，不过从udp_send_skb到ip_send_skb再到netdev_start_xmit还没找到代码能衔接上，还在继续找。
