„Linux-libre“ – Versionsunterschied

Vorlage:Distinguish Vorlage:Other uses Vorlage:Notability Vorlage:Primary sources Vorlage:Self-published Vorlage:Infobox software Linux-libre is a project that releases and maintains modified versions of the Linux kernel. Their kernel version removes any software that does not include its source code, has its source code obfuscated or released under proprietary licenses. The parts that have no source code are called binary blobs and are generally proprietary firmware. Linux-libre is endorsed by the Free Software Foundation, and it is a main piece of the totally free GNU distributions. Linux-libre is maintained and released by the Free Software Foundation Latin America (FSFLA).

Elimination of proprietary firmware

The cleaning process is achieved by using a script called deblob-main. This script is inspired by the one used for gNewSense. Jeff Moe made subsequent modifications ​​to meet certain requirements for its use with the BLAG Linux and GNU distribution. There is another script called deblob-check, which is used to check if a kernel source file, a patch or a compressed sources file still contains software suspicious of being proprietary.

Disadvantages

Vorlage:Unreferenced section The elimination of proprietary drivers from the kernel precludes the use of Linux-libre on hardware that has not yet compatibility with free software, such as some sound, video and wireless network cards, and other devices. Whenever it is possible, free drivers are included as substitutes.Vorlage:Citation needed

In addition, it has been discovered that the act of eliminating all references to closed but legally redistributable firmware needed for a driver to run correctly at the source code level effectively renders the driver (and its corresponding hardware) unworkable under any circumstances, even if a user has a copy of the correct firmware placed into the /lib/firmware directory. This effectively makes the Linux-libre kernel almost useless for mainstream desktop computing, as most devices today (especially networking hardware) require the use of such firmware in order to function at all.Vorlage:Citation needed

Linux-libre distributions

Trisquel implements 100% free kernels based on Linux-libre since version 2.1.

The following distributions use or have available Linux-libre as its kernel:

Amagi Arch Linux BLAG Linux and GNU Canaima ConnochaetOS Dragora Gentoo Linux gNewSense

Kongoni NeonatoX GNU/linux-libre Parabola GNU/Linux-libre RMS GNU/Linux-libre Tlamaki GNU/Linux Trisquel Venenux GNU/Linux

In addition, the following distributions are planned to include Linux-libre as its kernel:

• dyne:bolic
• Musix GNU/Linux

Availability

The source codes and precompiled packages of different versions of the debugged kernel recognized by the Linux-libre project are available on the respective pages of the different distributions or individual programmers. Freed-ora is a sub Libre-libre subproject that prepares and maintains RPM packages based on the Fedora kernel. There are also precompiled packages for Debian and derived distributions such as Ubuntu.

Real-time version

Andrew Morton, a developer of the Linux kernel.

The kernel of dyne:bolic has the particularity of have been compiled to work in real-time, giving it a better performance for multimedia editing. In addition, a precompiled version with realtime patches from Andrew Morton is available on the LTS versions of Trisquel as an optional download.

Mascots of Linux-libre

Freetz is the older brother of the current mascot of Linux-libre.

• Stux: It was the first mascot and it is a picture of a clean penguin, hanging to dry after washing. It was taken by Lewis Laë, who granted a permission to FSFLA to used it on its website; however, is not covered by a free license. Then, there was made a call to artists and graphic designers to create a mascot that shows the freedom gained by the penguin, as Stux, although clean, is still in prison.

The mascots that emerged by the call and are shown on the Linux-libre project website are:

• Freetz: Drawn by Burnaron, it represents a free penguin that just got out of the shower, published in two versions: raster and vector graphics.
• Lux: Drawn by Guillaume Pasquet, it represents the holy free penguin (with angel wings and an aureola), made ​​based on Tux (by Larry Ewing), official mascot of the standard Linux kernel.
  • Levitating Gnu and Lux: It's a composition by Alexandre Oliva of the levitating gnu, one of the logos of the GNU project, playing the flute to free Lux, making it levitate out of the cage where he was imprisoned. It was published in two versions: raster and vector graphics.
• Freedo: It is the current official mascot of the Linux-libre project. It is a modified version of Freetz by Ruben Rodríguez Pérez. There is also a gray alternative for printing created by Fernando.
  • Freedo with GNU: Alexander Oliva also created a combination of Freedo with the GNU logo, creating a logo that can be used to show on the kernel boot.
