软件

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

如果在编译的时候遇到了如下的错误:

 

  CC      applets/applets.o
In file included from /usr/include/bits/errno.h:24,
                 from /usr/include/errno.h:35,
                 from include/libbb.h:17,
                 from include/busybox.h:8,
                 from applets/applets.c:9:
/usr/include/linux/errno.h:1: fatal error: asm/errno.h: No such file or directory

 

那么需要安装下面的软件包:

sudo apt-get install linux-libc-dev:i386

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:
