note LK group for Linux Libre Kernel hacktivists
LAST OUT '3.1.0 linux libre kernel .deb available from October the 24 2011'
'You work on different type of architecture and/or operating system please join'
website http://www.fscorsica.org (At the time you have build a linux libre kernel without modification on the base configuration you are welcome to link your website to share your works)
architecture 64 bits
operating system Debian Squeeze on fully free repositories
Mirror You can add to your mirror list our mirror

The Linux Libre Kernel Group as been created to help people to construct and compile their own Linux Libre Kernel from http://www.fsfla.org
1st goal establish a working compilation recipe (without change from the basic linux kernel configuration distributions but free as in freedom)
2nd goal offer a Linux Libre Kernel Optimization Solution - LKOS a guide to bring some optimizations on your own linux libre kernel
3rd goal keep old recipe at fscorsica.org/old to offer solutions for people which need to works on old solutions
One of the simply way to compile your own Linux Libre Kernel for your distribution is
(This example as been made on a Full Libre GNU / Linux Debian Operating System)
You can find the .deb of this linux libre kernel at :: http://www.fscorsica.org/kernel-en.html
You can find the .deb of an LKOS example at :: http://www.fscorsica.org/lkos-en.html

Linux Libre-Kernel version :: 3.1.0

Type: GNU documentation

Made on Operating System : Debian Sqeeze with free software only
Distribution: GNU / linux
This part is important and long (depending on the computers you have got)
If you are running on a fresh install or if you never made that type of operation before, you will need to install packages needed for linux libre kernel compilation. First, make sure your apt database is updated
All command must be made under root
Get the root power with su or sudo
su aptitude update
Install the needed packages
aptitude install fakeroot kernel-package libncurses5-dev libqt3-mt-dev bzip2 wget build-essential
In a web browser go to last linux libre kernel release you can launch from another buffer of your emacs or terminal if you use tty
links http://www.linux-libre.fsfla.org/pub/linux-libre/releases/
Copy the link adress of the linux libre kernel version you want.
In a terminal go to /usr/src and get the source :
wget http://www.linux-libre.fsfla.org/pub/linux-libre/releases/3.1-libre/linux-3.1-libre.tar.bz2
Uncompress the archive file
tar xvjf linux-3.1-libre.tar.bz2
Go to the newly created directory of the uncompressed source
cd linux-3.0.4
Enter
make clean mrproper
Now, you can review and change config variables. First, update your config file to the new options of the linux libre kernel source
make nconfig F6 to save the .config F9 to quit
This will open an application that classifies and explains the properties and available modules you can either 'build into' the linux libre kernel, make modularly available or disable. When you are done, save it and exit.
make-kpkg clean
Now you have to modify a file ::
Modify the version.h file in the linux-3.1/include/linux containing ::
emacs include/linux/version.h #define UTS_RELEASE "3.1.0-libre-planet" <- (here change libre-planet by what you want)
C-x C-s save the file in /usr/src/linux-3.0.4/include/linux/version.h
Now, you can build your linux libre kernel, enter
fakeroot make-kpkg --initrd --append-to-version=-planet kernel_image kernel_headers kernel_source
You can change "planet" by the value you have choose when you have create the utsrelease.h file. Optionally, you can add kernel_source at the end, if you want to build a source pack. You can also put CONCURRENCY_LEVEL=N (where N should be replaced by the number of CPU cores your computer has) at the beginning of the command to make the building process take advantage of multiple core systems.
The last command will take some time to complete. At the end, you will have linux-image and linux-headers (and linux-source if you chose) installation files.
go to linux-image and linux-headers files to the directory you want. Then, either go to that directory in terminal with cd command and install the two .deb packages:
Now you've got your own libre-kernel files in /usr/src
dpkg -i linux-image-3.1.0-libre-planet.deb dpkg -i linux-headers-3.1.0-libre-planet.deb dpkg -i linux-source-3.1.0-libre-planet.deb
Or
dpkg -i *b (if the directory is clean)
Or, just double-click on the two files and click on the Install Package button.
Restart and choose libre-planet kernel from your GRUB.
If you build you own Linux Libre Kernel and share it arround it can be usefull to generate the md5 checksum
md5sum linux-image-3.1.0-libre-planet.deb > linux-image-3.1.0-libre-planet.deb.md5
