Buil Customs Kernel on Debian How to ??

Buil Customs Kernel on Debian How to ??

This Will Give U a Complete Procedure How To Compile Kernel on Debian on Right Way :

I give Wheezy Try :

If you're going to follow the procedures recommended in this document, your non-root user account must be enrolled in the "src" group.  For example,
 
          # mkdir /usr/src/build
          # mkdir /usr/src/build/kernel
# adduser fa src

Also, make sure that the directory /usr/src is owned by user root and by group src, and that the group has read and write privileges on the directory.  Execute privileges on the directory should be granted to all users (user, group, and other).  Also, make sure that the "set-group-ID" file mode bit is set for the directory.  This can be checked by issuing "ls -ld /usr/src".  The "s" flag will show in the output.  For example:
 
           $ ls -ld /usr/src drwxrwsr-x 3 root src 4096 Aug 24 13:52 /usr/src

The letter "s" in the seventh position of the file attributes indicates that the "set-group-ID" file mode bit is set for the directory.  This used to be the default, but on a recent install of Squeeze I've seen this change.  If it is not set, set it using the following command:
 
          #chgrp -R usr /usr/src
          # chmod g+s /usr/src
          #chmod -R g+w /usr/src
          #chown -R fa:src /usr/src/build/kernel -> change 'fa' with your own username

(Any changes to the privileges on the /usr/src directory must be done by root.)  Once you select a non-root user account for kernel-building purposes, you must use that same userid for all non-root steps.
Update The Sources.lit , Here My Example :

deb http://ftp.debian.org/debian/ wheezy main non-free contrib
deb-src http://ftp.debian.org/debian/ wheezy main non-free contrib
deb http://security.debian.org/ wheezy/updates main non-free contrib
deb-src http://security.debian.org/ wheezy/updates main non-free contrib

U can add the Mirror To add Faster Repository :
deb http://ftp.us.debian.org/debian wheezy main non-free contrib
deb-src http://ftp.us.debian.org/debian wheezy main non-free contrib
deb http://debian.corenetworks.net/debian/ wheezy main contrib non-free
deb-src http://debian.corenetworks.net/debian/ wheezy main contrib non-free
deb http://debian.mirrors.tds.net/debian/ wheezy main contrib non-free
deb-src http://debian.mirrors.tds.net/debian/ wheezy main contrib non-free
deb http://ftp.utexas.edu/debian/ wheezy main contrib non-free
deb-src http://ftp.utexas.edu/debian/ wheezy main contrib non-free
deb http://mirrors.xmission.com/debian/ wheezy main contrib non-free
deb-src http://mirrors.xmission.com/debian/ wheezy main contrib non-free


When mixing releases in the same system, it is important to define the default release.  You do this in /etc/apt/apt.conf.  Put a line such as the following in the above-named file:
 
APT::Default-Release "wheezy";
     Aptitude::Purge-Unused "true";
     
Then use :
 
#aptitude updade && aptitude full-upgrade
          #update-initramfs -u -k $(uname -r)

to install the updates.  If you are running the testing release or the unstable release, you should perform this procedure regularly, since updates are not generally announced.  When you are finished installing package updates, use 
 
#aptitude clean

Got The Source From Here :

$cd /usr/src
$links http://www.kernel.org/

choose  the kernel version you need, grab it with push 'D'

untar it, i use kernel 3.2.2 , so the command wil be :

tar -xjf linux-source-3.2.2.tar.bz2

Do this step as root.  If you have not already done so, install the "kernel-package" package.  You can check to see if it is already installed by using
 
dpkg-query -l kernel-package|grep ii
If it is not already installed, install it. 
 
aptitude install kernel-package

Read the README file for kernel-package.
 
zless /usr/share/doc/kernel-package/README.gz

At the time of this writing, the following packages will be required for the menuconfig method under Debian Squeeze:
 
gcc
     libc6-dev
     bin86 (i386 and amd64 architectures only)
     libncurses5-dev
     binutils
     make
     module-init-tools
     mawk | gawk
     gzip
     coreutils
     grep
     zlib1g-dev (if CONFIG_LGUEST is set)
     fakeroot (if building the kernel as a non-root user)

Many of these packages will already be installed.  To check to see if these packages are installed, use dpkg-query.  For example:
 
dpkg-query -l gcc|grep ii

Install those packages which you need with "aptitude install".  For example:
 
aptitude install bin86 libncurses5-dev zlib1g-dev fakeroot && aptitude clean

There may also be some packages needed to install the kernel image package once it has been built.  For example, you may need initramfs-tools to build the initial RAM file system image file during kernel image package installation.  (But it should be installed already.)

At this point I recommend that you edit the kernel-package config file (/etc/kernel-pkg.conf) and change the "maintainer" and "email" tags to your own name and e-mail address.

No need for the patch since we use 64 kernel, i think so :
but if you are using 32 bit , you wiill need it for patch the Doumentation.

No apply the patch, issue the following sequence of commands:
 
cd /usr/share/kernel-package
     ... (download the patch file to the current directory)
     patch -p1 <patch3xx.diff

Configure The Kernel :

Do this step as a non-root user.  Use the same userid for all non-root steps.  The non-root user must be a member of group "src".  First, change directories to the home directory for the source code.
 
cd /usr/src/build/kernel/linux-source-3.2.2

Now, initialize the .config file based on the configuration file used by the stock Debian kernel.
 
cp /boot/config-2.6.32-5-686 .config

This means that if you make no changes, your custom kernel will be configured exactly like the stock Debian kernel.  Obviously, adjust the name of the config file to copy based on your architecture and kernel release.  The file you need will start with "config" and will have your kernel version name in it.
Now it's time to configure the kernel:
 
make menuconfig

OK, with all that said, we are ready to start issuing commands.  If you are running Lenny (or previous releases), issue the following command:
 
make-kpkg clean

Under Lenny and previous releases it is necessary to run make-kpkg with the "clean" target after each invocation of "make menuconfig" (or any *config target, actually).  Otherwise, the --append-to-version and/or the --revision flags won't work properly.  If you are running Squeeze or later releases, the above command may be omitted.  (But if you do run it under Squeeze and later releases, it won't do any harm.)  Now issue the following command to build the package(s):

This For Debian Kernel Ways : ( If you download it from Debian Repository) :
 
time CONCURRENCY_LEVEL=8 make-kpkg --append-to-version -5custom1-686 --revision 2.6.32-38 --initrd --rootcmd fakeroot kernel_image modules_image
And This For My Own Ways, since it from Kernel Source :

CONCURRENCY_LEVEL=8 fakeroot make-kpkg --append-to-version -2fa4-666 --revision 7.5.88-1 --initrd kernel_image kernel_headers

Even if you are running Squeeze or later I suggest that you read this section because material covered here is assumed as background knowledge in later sections.
The /etc/kernel-img.conf file for a default Lenny installation on the i386 architecture with the grub version 1 boot loader (the default) looks something like this:
 
# Kernel image management overrides
     # See kernel-img.conf(5) for details
     do_symlinks = yes
     relative_links = yes
     do_bootloader = no
     do_bootfloppy = no
     do_initrd = yes
     link_in_boot = no
     postinst_hook = update-grub
     postrm_hook   = update-grub


Now We Already Have a new kernel, it;s time to install it :
Do this step as root.  OK, now it's time to actually install the kernel image package.  You won't use aptitude or apt-get to install the kernel image package.  That is due to the fact that it doesn't have to be fetched from anywhere.  Instead, use the low-level package tool dpkg.
 
cd /usr/src dpkg -i linux-image-2fa4-666_7.5.88-1_amd64.deb

Do this step as root.  Shutdown and reboot to run your new custom kernel!
 
shutdown -F -r now;exit

Now i't time to clean up home :
Do this step as a non-root user.  Use the same userid for all non-root steps.  The non-root user must be a member of group "src".  Once the new kernel image package has been installed, you can delete the package file (.deb file). 
 
#cd /usr/src/build/kernel
#rm linux-image-2.6.32-5custom1-686_2.6.32-38_i386.deb
If you have also installed one or more modules image packages, you can delete their package files too.  The same goes for a linux-headers-* package.

Clean Up :
Do this step as root.  Once you are satisfied with the new kernel, you may wish to de-install the old kernel image package.  I like to keep at least one back version unless I know that the old kernel will no longer work due to changes made since migrating to the new kernel.  For example, if my system now depends on a kernel module that did not exist in the old kernel, there's not much point in keeping the old kernel around.
 
aptitude purge linux-image-2.6.32-5-686

Done.,
:)
