The old Linux kernel source version 0.11 and the integrated experiment environment.
CS630 Qemu Lab is a related project, it is a friendly learning environment for the X86 assembly course: CS630.
If want to learn the latest Linux Kernel, please try our Linux Lab
-
Basic information
- Homepage: http://tinylab.org/linux-0.11-lab
- Repository: https://github.com/tinyclub/linux-0.11-lab
-
Features
- compilable with many different versions of Gcc.
- has been tested under modern Linux, Mac OS X.
- add bulit-in qemu and bochs support, include running and debugging.
- integrate different prebuilt rootfs (floopy, ramdisk and harddisk).
- allow to generate callgraph of every specified function
- a Dockerfile added to simplify this setup on other systems (e.g. Windows).
- The Linux distributions: debian and ubuntu (>= 14.04) are recommended
- Install the lab
In localhost:
$ tools/install-local-lab.sh
With Docker:
$ tools/install-docker-lab.sh
$ tools/run-docker-lab.sh
$ tools/open-docker-lab.sh
- The above command will start a VNC page, login with the password printed in the console
$ make help // get help
$ make // compile
$ make start-hd // boot it on qemu with hard disk image
$ make debug-hd // debug it via qemu & gdb, you'd start gdb to connect it.
$ make start-hd G=0 // Use curses based terminal instead of graphics, friendly for ssh login
$ make switch // switch to another emulator, between qemu and bochs
Switch to use emulator: bochs
$ gdb images/kernel.sym
(gdb) target remote :1234
(gdb) b main
(gdb) c
$ gdb boot/bootsect.sym // debug bootsect, step one instruction
(gdb) target remote :1234
(gdb) b _start
(gdb) si
$ gdb boot/setup.sym // debug setup, similar as above
(gdb) target remote :1234
(gdb) b _start
(gdb) si
Optional
$ echo "add-auto-load-safe-path $PWD/.gdbinit" > ~/.gdbinit // let gdb auto load the commands in .gdbinit
Note: A simpler method is use Docker Toolbox with our Dockerfile, see Build on the other systems
-
Install xcode from "App Store"
-
Install Mac package manage tool: MacPorts from http://www.macports.org/install.php
-
Check your OS X version from "About This Mac", for example, Lion
-
Go to the "Mac OS X Package (.pkg) Installer" part and download the corresponding version
-
Self update MacPorts
$ xcode-select --switch /Applications/Xcode.app/Contents/Developer $ sudo port -v selfupdate
-
-
Install cross compiler gcc and binutils
$ sudo port install i386-elf-binutils i386-elf-gcc -
Install qemu
$ sudo port install qemu -
Install graphviz and cflow
$ sudo port install GraphViz $ sudo port install cflow -
Install gdb. 'Cause port doesn't provide i386-elf-gdb, use the pre-compiled tools/mac/gdb.xz or download its source and compile it.
$ cd tools/mac/ ; tar Jxf gdb.xz
Optional
$ sudo port install cscope
$ sudo port install ctags
$ wget ftp://ftp.gnu.org/gnu/gdb/gdb-7.4.tar.bz2
$ tar -xzvf gdb-7.4.tar.bz2
$ cd gdb-7.4
$ ./configure --target=i386-elf
$ make
Same as Hack Linux-0.11 on Linux
If want to use this Lab on the other systems, such as Windows (and even Mac OS X), with the Dockerfile support, everything is simplified.
Only need to install the docker toolbox, which is a lightweight Linux distribution made specifially to run Docker containers, with this tool and our Dockerfile, we can simply build a Linux 0.11 Lab on every system.
-
Install Docker Toolbox and boot into it
please follow Docker Toolbox Installation.
-
Build and Start the service
$ tools/install-docker-lab.sh $ tools/run-docker-lab.sh $ tools/open-docker-lab.sh -
The above command with start a VNC page, login with 'ubuntu' password
Same as Hack Linux-0.11 on Linux
Three different root filesystem images are stored in rootfs/:
- rootram.img -- RAM image
- rootimage -- Floppy image
- hdc-0.11.img-- Harddisk image
rootram.img is mountable directly:
$ mkdir /path/to/rootram/
$ sudo mount -o rootfs/rootram.img /path/to/rootram/
rootimage-0.11 is a minix filesystem, must with -t minix obviously:
$ sudo mkdir /path/to/rootimage/
$ sudo mount -t minix rootfs/rootimage-0.11 /path/to/rootimage
hdc-0.11.img has a partition table, should be mounted with an offset:
$ mkdir /path/to/hdc/
$ fdisk -lu rootfs/hdc-0.11.img
$ fdisk -l rootfs/hdc-0.11.img
Disk rootfs/hdc-0.11.img: 127 MB, 127631360 bytes
16 heads, 38 sectors/track, 410 cylinders, total 249280 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000

$ sudo mount -o offset=$((2*512)) rootfs/hdc-0.11.img /path/to/hdc/
