Make sure your hardware and device

A clear head and relaxed mind

Some drinks and food

LOGO Compiling Linux kernel

What is Linux Kernel?

Kernel is the core of an operating system.

Scheduler, task management, memory management, …

You need to compile kernel source code to binary in order to run.

When Should We Compile Kernel?

You don’t need to compile kernel after Linux installation to run.

You can configure your Linux by compiling a new kernel.

Add new feature, ex. patch kernel.

Support new hardware.

Disable functions you don’t need.

Develop your own kernel.

Etc.

Where to D/L Linux Kernel?

http://www.kernel.org/

What Does Kernel Version Mean?

Naming using [主版本 ].[次版本 ].[修訂版本 ]-

[附版本 ].Odd minor number is testing version.

Even minor number is stable version.

Prepare Your Kernel Source Code

1. You need to be root to compile kernel.#su

2. D/L kernel source code.http://www.kernel.org

3. Unzip kernel source code.cd /usr/srctar -zxvf linux-2.x.x.tar.gz

4. Make the link “/usr/src/linux-2.x.x” to the kernel source directory.

#ln –s linux-2.x.x linuxYou may have many versions of Linux source codes

make config

#make config

#make menuconfig

#make xconfig

make config

make config(cont.)If you meet some problems . (SATA)

Device Drivers --->

SCSI device support ---> SCSI low-level drivers ---> [*] Serial ATA (SATA) support

Kernel Compilation

1. #make clean

2. #make bzImage

3. #make modules

4. #make modules_install

5. #mkinitramfs –o /boot/filename 2.x.x

6. (/lib/modules/)

Booting using New Kernelcp /usr/src/linux/arch/i386/boot/bzImage /boot/vmlinuz-2.x.x

Setup your boot manager.Lilo or Grub

Grub

# vim /boot/grub/menu.lst

Add the following section:title linux-2.x.x kernel (hd0,0)/boot/vmlinuz-2.x.x root=/dev/hda1

devfs=mount

Reboot.

Any problem
