观测 e1000 驱动在 qemu 如何被模拟的
- 为什么 alpine 天然的可以支持网络(wget www.baidu.com, 开箱即用)
-
很奇怪，这里地址空间还是存在 kvm 的一些设备，那么 guest 内核无法知道
- gdb 的使用有点奇怪啊，似乎需要严格按照 http://nickdesaulniers.github.io/blog/2018/10/24/booting-a-custom-linux-kernel-in-qemu-and-debugging-it-with-gdb/ 的方法操作
- https://stackoverflow.com/questions/49360506/in-kgdb-i-cannot-set-the-breakpoint : 这里给出来一个解决方法
e1000 作为 pci 设备是如何挂载的，调试一下内核吧!

- 设备是如何初始化的
- 设备在系统启动的时候，会将两个
- 驱动和设备如何绑定?
- 应该是 driver 会告诉自己匹配的 vendor 和 function

kernel_init 是从 rest_init 初始化的最开始两个线程中间一个，这个之后会切换为用户态进程的:
模拟网络 stack 的方法
是不是 PCI device 使用的空间是
好的，模拟的 stack 已经是搞清楚
