  1. Setup and Compile Linux Kernel Speaker: Yi-Ji Jheng Date: 2007.10.31

  2. Outline • Understand Linux Kernel • Setup and Compile Linux Kernel • Setup and Compile micro-Linux Kernel

  3. UNDERSTAND LINUX KERNEL

  4. Where is Kernel ? User Shell Shell, KDE, AP. Kernel Hardware Kernel Hardware

  5. What is Kernel ? • Kernel(widely) • Code • Used by application • Control hardware • Hardware driver • Modularization of driver • Dynamic • Static

  6. Role of Kernel when boot (1/2) • 1. Boot • Turn on PC • 2. Read BIOS • Know boot device of sequence • 3. Read MBR(Master Boot Record) on H.D. • If the boot device is H.D. that we set

  7. Role of Kernel when boot (2/2) • 4. Execute the Boot Loader • We use GRUB that is a kind of Boot Loader • Load Kernel in main memory • 5. Kernel work • Decompress itself • Know File System * • Mount “/” and load modules • Run • Detect and drive hardware • 6. Run first program - init

  8. Why need to make kernel ? • Stable • Make system match your hardware • New hardware support • Other • Embedded system

  9. Get Linux Kernel • http://www.kernel.org/ • 交大資科：ftp://linux.cis.nctu.edu.tw/kernel/ • 義守大學：http://ftp.isu.edu.tw/pub/Linux/kernel/

  10. Setup and Compile Linux Kernel

  11. Setup (1/2) • #tar zxvf linux-2.4.25.tar.gz • #cd ./linux-2.4.25 • #make mrproper • Clean all of old *.o • #cp /boot/config-2.4.20-8 ./.config • Use default (Host Linux) setup to modify

  12. Setup (2/2) • #make menuconfig • A text mode to select modules that we want • Press “Y”, means to include in Kernel • Press “M”, means to be modules • Press “N”, means not to be modules and don’t include in Kernel

  13. Modify SCSI setup • <M>SCSI support --> <*> • <M>SCSI disk support --> <*> • SCSI low-level drivers <M>BusLogic SCSI support ---> <*> • Save and quit

  14. Make Kernel (1/2) • #make dep • Check dependency • #make bzImage • Make Kernel and compress to bzImage • #make modules

  15. Make Kernel (2/2) • #make modules_install • After install, modules would locate in /lib/modules/<kernel version> • #cp -a ./arch/i386/boot/bzImage /boot/bzImage-2.4.25 • Install Kernel by manual

  16. Modify GRUB • #vi /boot/grub/grub.conf title Red Hat Linux (2.4.25) root (hd0,0) kernel /bzImage-2.4.25 ro root=/dev/sda2 • Save and quit

  17. Reboot • Reboot and select your new Kernel

  18. Setup and Compile micro-Linux Kernel

  19. Setup • #cd ./linux-2.4.25 • #make clean • #make menuconfig • Disable all modules, unless mention below • Tip : disable all modules first before you want to select

  20. Processor type and features • Processor type and features ---> (386) Processor family

  21. General setup • General setup ---> [*] Networking support [*] PCI support (Any) PCI access mode (ELF) Kernel core (/proc/kcore) format [*] Kernel support for ELF binaries

  22. Networking options • Networking options ---> [*] Packet socket [*] Unix domain sockets [*] TCP/IP networking [*] IP: multicasting

  23. SCSI support • SCSI support ---> [*] SCSI support [*] SCSI disk support [*] Probe all LUNson each SCSI device • SCSI low-level drivers ---> [*] BusLogicSCSI support

  24. Network device support • Network device support ---> [*] Network device support • Ethernet (10 or 100Mbit) ---> [*] Ethernet (10 or 100Mbit) [*] EISA, VLB, PCI and on board controllers [*] AMD PCnet32 PCI support

  25. Character devices • Character devices ---> [*] Virtual terminal [*] Support for console on virtual terminal [*] Standard/generic (8250/16550 and compatible UARTs) serial support

  26. File systems • File systems ---> [*] Ext3 journallingfile system support [*] /proc file system support [*] Second extended fssupport

  27. Console drivers • Console drivers ---> [*] VGA text console

  28. Modify version of information • #vi ./include/linux/version.h #define UTS_RELEASE "2.4.25-min"

  29. Make Kernel • #make dep • #make bzImage • #cp -a ./arch/i386/boot/bzImage /boot/bzImage-2.4.25-min

  30. Modify GRUB • #vi /boot/grub/grub.conf title Red Hat Linux (2.4.25-min) root (hd0,0) kernel /bzImage-2.4.25-min ro root=/dev/sda2 • Save and quit

  31. Reboot • Reboot and select your new Kernel

  32. REPLENISH

  33. Kernel vs. File System • If Kernel don’t know your File System • Must make a Initrd(Initial RAM Disk) • linuxrc that can let Kernel know File System of modules • Kernel can know File System after it use Initrd to load module first
