Kernelnewbies is a community of aspiring Linux kernel developers who An effort to organize all the pieces of useful information on the Internet about kernel hacking To learn more about what a WikiWikiWeb is, read about. Learn how to develop for the Linux kernel. In this course you'll learn how Linux is architected, the basic methods for developing on the . Live Online (Virtual). This chapter introduces some of the basics of the Linux kernel. you can obtain and subsequently keep up to date with the official kernel tree. is outside the scope of this book; many online resources provide excellent guides.

Using Git Over the last couple of years, the kernel hackers, led by Linus himself, have begun using a new version control system to manage the Linux kernel source.
Linus created this system, called Git, with speed in mind. Unlike traditional systems such as CVS, Git is distributed, and its usage and workflow is consequently unfamiliar to many developers. I strongly recommend using Git to download and manage the Linux kernel source.

You can use Git to obtain a copy of the latest "pushed" version of Linus's tree: To commit and manage your own changes, see Chapter 20, "Patches, Hacking, and the Community. Bzip2 is the default and preferred format because it generally compresses quite a bit better than gzip.Kernel Recipes 2017 - Understanding the Linux Kernel via Ftrace - Steven Rostedt
The Linux kernel tarball in bzip2 format is named linux- x. After downloading the source, uncompressing and untarring it is simple. If you use git to obtain and manage the kernel source, you do not need to download the tarball.
Just run the git clone command as described and git downloads and unpacks the latest source. The goal is to release a new -rc kernel every week.
It is worth mentioning what Andrew Morton wrote on the linux-kernel mailing list about kernel releases: They contain relatively small and critical fixes for security problems or significant regressions discovered in a given 4. The normal release period is approximately two weeks, but it can be longer if there are no pressing problems.
A security-related problem, instead, can cause a release to happen almost instantly.

They are more experimental than -rc kernels since they are generated automatically without even a cursory glance to see if they are sane. That way, others can see what is happening in the different areas of the kernel. In areas where development is rapid, a developer may be asked to base his submissions onto such a subsystem kernel tree so that conflicts between the submission and other already ongoing work are avoided. Most of these repositories are git trees, but there are also other SCMs in use, or patch queues being published as quilt series.

Many of them can be browsed at https: Before a proposed patch is committed to such a subsystem tree, it is subject to review which primarily happens on mailing lists see the respective section below. For several kernel subsystems, this review process is tracked with the tool patchwork.
Patchwork offers a web interface which shows patch postings, any comments on a patch or revisions to it, and maintainers can mark patches as under review, accepted, or rejected. Most of these patchwork sites are listed at https:
