Kernel/fr

The Linux kernel is the core of the operating system and offers an interface for programs to access the hardware. The kernel contains most of the device drivers.

USE flags
To create a kernel, it is necessary to install the kernel source code first. The Gentoo recommended kernel sources for a desktop system are, of course,. These are maintained by the Gentoo developers, and patched to fix security vulnerabilities, functional problems, as well as to improve compatibility with rare system architectures.

Alternative kernels
Il existe plusieurs sources alternatives du noyau dans l'arbre de Portage :


 * - The official, non-patched Linux kernel sources. These sources are left as is, they do not contain any additional patches and are therefore not supported by Gentoo support or developers.
 * - Gentoo sources with security enhancements.

Sources overview

 * Kernel sources overview: Most, if not all, of the kernel sources packages available in Gentoo are detailed in the kernel sources overview article. Navigate there for further knowledge on specific kernel sources available in the Portage tree.

Configuration help

 * Automatic configuration: genkernel is a tool used to automate the build process of the kernel and initramfs. The goal of genkernel is to help users through the kernel building process.


 * Manual configuration: Manual configuration enables the user, with some effort, to create a custom-fit kernel configuration.


 * Gentoo kernel configuration guide: Gentoo's kernel configuration guide.


 * Mise à jour: Étapes à suivre pour mettre à jour votre noyau vers une nouvelle version à partir d'une configuration existante.


 * Suppressions: Étapes à suivre pour retirer totalement d'anciens noyaux.


 * Kernel Seeds: Like the option above, Kernels Seeds help the user, with some effort, create a custom-fit kernel configuration using an existing as a base.


 * 2.4 to 2.6 Migration: Migration guide from Linux 2.4 to Linux 2.6. Since the Linux kernel codebase has significantly moved past 2.6, these migration steps are no longer relevant, but may be useful for helping administrators understand.
