Host： Ubuntu14.04 64
Qemu 2.8.0
Linux 2.6.24
busybox 1.24.2
gcc 4.4.7
概述
为了尽量还原《深入Linux内核架构》这本书的环境，我下载了Linux 2.6.24，由于这个内核版本比较老，所以用最新的gcc编译会有问题，所以需要安装一个比较老的gcc，从该内核的README得知，gcc的版本最少应该是3.2.
正文
一、安装GCC
使用apt-cache search gcc发现，目前可以安装的最老的gcc版本是4.4，安装命令如下：
sudo apt-get install gcc-4.4*
为了便于跟原来的高版本的gcc切换，可以使用下面的命令：
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.8 0 sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.4 1
这样，在切换gcc版本时就方便多了，可以使用下面的命令切换：
sudo update-alternatives --config gcc
此时会列出如下信息：
There are 2 choices for the alternative gcc (providing /usr/bin/gcc). Selection Path Priority Status ------------------------------------------------------------ 0 /usr/bin/gcc-4.4 1 auto mode * 1 /usr/bin/gcc-4.4 1 manual mode 2 /usr/bin/gcc-4.8 0 manual mode Press enter to keep the current choice[*], or type selection number:
根据需求选择我们需要的版本即可。
二、编译Linux内核
编译命令如下：
#!/bin/bash make ARCH=i386 i386_defconfig make ARCH=i386 menuconfig make ARCH=i386 bzImage V=1 -j8
在编译的时候会提示如下的错误：
arch/x86/boot/boot.h: Assembler messages: arch/x86/boot/boot.h:112: Error: bad register name `%dil‘
也就是下面的一行代码出现问题：
asm volatile("movb %%fs:%1,%0" : "=r" (v) : "m" (*(u8 *)addr));
在网上搜索一番后，出现这个问题的原因如下：（http://nxlhero.blog.51cto.com/962631/702421/）
"r"表示的时任何寄存器，而dil寄存器时x86_64上才有的，所以将上面的"=r"换为"=q"，即限定为只能选eax,ebx,ecx,edx之一。
修改完成后，就可以编译通过了。
支持ramdisk：
General setup ----> [*] Initial RAM filesystem and RAM disk (initramfs/initrd) support Device Drivers ----> [*] Block devices ----> (16) Default number of RAM disks ----> (65535) Default RAM disk size (kbytes) ----> (1024) Default RAM disk block size (bytes)
三、制作跟文件系统
这一节参考用Qemu搭建x86学习环境
制作脚本mk_ramdisk.sh稍有不同：
#!/bin/bash sudo rm -rf rootfs sudo rm -rf tmpfs sudo rm -rf ramdisk* sudo mkdir rootfs sudo cp /home/pengdonglin/disk_ext/Third_Part/Busybox/x86_2_6_24/_install/* rootfs/ -raf sudo mkdir -p rootfs/proc/ sudo mkdir -p rootfs/sys/ sudo mkdir -p rootfs/tmp/ sudo mkdir -p rootfs/root/ sudo mkdir -p rootfs/var/ sudo mkdir -p rootfs/mnt/ sudo cp etc rootfs/ -arf sudo mkdir -p rootfs/lib sudo cp -arf /lib/i386-linux-gnu/* rootfs/lib/ sudo rm -f rootfs/lib/*.a sudo strip rootfs/lib/* sudo mkdir -p rootfs/dev/ sudo mknod rootfs/dev/tty1 c 4 1 sudo mknod rootfs/dev/tty2 c 4 2 sudo mknod rootfs/dev/tty3 c 4 3 sudo mknod rootfs/dev/tty4 c 4 4 sudo mknod rootfs/dev/console c 5 1 sudo mknod rootfs/dev/null c 1 3 sudo dd if=/dev/zero of=ramdisk bs=1M count=32 sudo mkfs.ext2 -F ramdisk sudo mkdir -p tmpfs sudo mount -t ext2 ramdisk ./tmpfs/ -o loop sudo cp -raf rootfs/* tmpfs/ sudo umount tmpfs
这里不需要压缩ramdisk，因为Linux 2.6.24不支持gzip压缩的ramdisk，我们直接使用制作出的32M的ramdisk就好了。
四、运行qemu
run.sh:
sudo qemu-system-i386 -smp 2 -m 1024M -kernel ./Linux-2.6.24/arch/x86/boot/bzImage -nographic -append "root=/dev/ram1 rw rootfstype=ext2 console=ttyS0 init=/linuxrc" -initrd ./rootfs/ramdisk -net nic,vlan=0 -net tap,vlan=0,ifname=tap0
注意上面的root是/dev/ram1，initrd使用的是未压缩的ramdisk。
五、启动log
$./run.sh
[sudo] password for pengdonglin:
sudo tunctl -u root -t tap0

sudo ifconfig tap0 0.0.0.0 promisc up
sudo brctl addif br0 tap0
