ello, I'm interested since a very long time in kernel development, but I never saw the right path to become familiar with parts of the kernel. I read a bit of ipc code and ext* code, but since I often don't know any possible next steps I moved back to something else in the user space.
I really like the tutorial on kernelnewbies.org FirstKernelPatch an I had the idea to create this type of tutorial as a training for specific kernel subsystems eg. ipc, file systems, usb drivers, ... A structure of such a tutorial could look like that: (eg scheduler) 1. Introduction / Goal [5 sentences of the goal - what should be archived by this tutorial] - understand scheduling in the linux kernel - write your own scheduler - ... 2. Preparation 2.1 Understand how to write a kernel patch: http://kernelnewbies.org/FirstKernelPatch 2.2 Understand the goal of Scheduling: https://en.wikipedia.org/wiki/Schedule 3. User space view 3.1 Read and understand: http://man7.org/linux/man-pages/man7/sched.7.html 3.1.1 Questions 3.2 Exercise: Write a program that does A 3.3 Exercise: Write a program that does B 3.4 Exercise: Write a program that does C 4. Kernel 4.1 Read and understand: http://man7.org/linux/man-pages/man7/sched.7.html 4.1.1 Questions 4.2 Read API description: http://... 4.3 Exercise (understanding): Read and understand function xxxx_yyyy() 4.4 Exercise (understanding: Change the implementation of xxxx_yyyy(), so that ... 4.5 Exercise (debugging): checkout version 123456 and fix the following (old) bug 4.6 Final Exercise (developing): Write your own scheduler with the following algorithm... In my opinion that could help a lot of interested people to have a guided tour though the kernel. It could really lower barriers, also in terms of the fear of communication. I am NOT able to to produce it by myself, but I can help to structure it, review it and also answer questions. I would also maintain them in case of changes and test the tutorials on a regular basis to keep them up to date. I also would improve the tutorial from a newbie point of view ;) If there is someone out there that is also interested in doing it please let me know. And if there is something like this out there please let me know, so I can maybe support this project :) Greetings, Patrick -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
