| 8: FOR MORE INFORMATION |
| |
| There are numerous sources of information on Linux kernel development and |
| related topics. First among those will always be the Documentation |
| directory found in the kernel source distribution. The top-level HOWTO |
| file is an important starting point; SubmittingPatches and |
| SubmittingDrivers are also something which all kernel developers should |
| read. Many internal kernel APIs are documented using the kerneldoc |
| mechanism; "make htmldocs" or "make pdfdocs" can be used to generate those |
| documents in HTML or PDF format (though the version of TeX shipped by some |
| distributions runs into internal limits and fails to process the documents |
| properly). |
| |
| Various web sites discuss kernel development at all levels of detail. Your |
| author would like to humbly suggest http://lwn.net/ as a source; |
| information on many specific kernel topics can be found via the LWN kernel |
| index at: |
| |
| http://lwn.net/Kernel/Index/ |
| |
| Beyond that, a valuable resource for kernel developers is: |
| |
| http://kernelnewbies.org/ |
| |
| Information about the linux-next tree gathers at: |
| |
| http://linux.f-seidel.de/linux-next/pmwiki/ |
| |
| And, of course, one should not forget http://kernel.org/, the definitive |
| location for kernel release information. |
| |
| There are a number of books on kernel development: |
| |
| Linux Device Drivers, 3rd Edition (Jonathan Corbet, Alessandro |
| Rubini, and Greg Kroah-Hartman). Online at |
| http://lwn.net/Kernel/LDD3/. |
| |
| Linux Kernel Development (Robert Love). |
| |
| Understanding the Linux Kernel (Daniel Bovet and Marco Cesati). |
| |
| All of these books suffer from a common fault, though: they tend to be |
| somewhat obsolete by the time they hit the shelves, and they have been on |
| the shelves for a while now. Still, there is quite a bit of good |
| information to be found there. |
| |
| Documentation for git can be found at: |
| |
| http://www.kernel.org/pub/software/scm/git/docs/ |
| |
| http://www.kernel.org/pub/software/scm/git/docs/user-manual.html |

| 9: CONCLUSION |
| |
| Congratulations to anybody who has made it through this long-winded |
| document. Hopefully it has provided a helpful understanding of how the |
| Linux kernel is developed and how you can participate in that process. |
| |
| In the end, it's the participation that matters. Any open source software |
| project is no more than the sum of what its contributors put into it. The |
| Linux kernel has progressed as quickly and as well as it has because it has |
| been helped by an impressively large group of developers, all of whom are |
| working to make it better. The kernel is a premier example of what can be |
| done when thousands of people work together toward a common goal. |
| |
| The kernel can always benefit from a larger developer base, though. There |
| is always more work to do. But, just as importantly, most other |
| participants in the Linux ecosystem can benefit through contributing to the |
| kernel. Getting code into the mainline is the key to higher code quality, |
| lower maintenance and distribution costs, a higher level of influence over |
| the direction of kernel development, and more. It is a situation where |
| everybody involved wins. Fire up your editor and come join us; you will be |
| more than welcome. |
