How do I start learning kernel development?

Start with kernel newbies. You do not need to read the full source code. Once you are familiar with the kernel API’s and its usage, directly start with the source code of the sub-system you are interested in. You can also start with writing your own plug-n-play modules to experiment with the kernel.

How do I get involved in Linux kernel development?

Contributing to the kernel

1. Step 1: Prepare your system.
2. Step 2: Download the Linux kernel code repository :
3. Step 3: Build/install your kernel.
4. Step 4: Make a branch and switch to it.
5. Step 5: Update your kernel to point to the latest code base.
6. Step 6: Make a change to the code base.

What is kernel programming in C?

The kernel is written in the C programming language [c-language]. More precisely, the kernel is typically compiled with gcc [gcc] under -std=gnu89 [gcc-c-dialect-options]: the GNU dialect of ISO C90 (including some C99 features). clang [clang] is also supported, see docs on Building Linux with Clang/LLVM.

Is kernel development hard?

Linux Kernel programming is hard and requires special skills. Linux Kernel programming requires access to special hardware. Linux Kernel programming is pointless because all of the drivers have already been written. Linux Kernel programming is time consuming.

What is kernel coding?

The kernel program runs in another memory area called “kernel space”. Kernel program always runs in a supper access mode. So from programming point of view, kernel programming means power to access anything and everything in a system.

How do I become a kernel maintainer?

In general, becoming a maintainer is a result of becoming involved in the general curation of a given component. If you do a good job, gain a reputation as someone reliable and trustworthy, and the appropriate circumstances arise, you’ll eventually have the opportunity to become a maintainer.

Can I create my own kernel?

If you are writing your own bootloader for loading a kernel you need to know the overall addressing/interrupts of memory as well as BIOS. Mostly each operating system has specific bootloader for it. We will use GNU GRUB to load our kernel because it supports a multiboot of many operating systems.

Which language is used in kernel?

C programming language
Most of the Linux kernel code is written using the GNU extensions of GCC to the standard C programming language and with the use of architecture specific instructions (ISA).

What are the jobs of a kernel?

The kernel performs its tasks, such as running processes, managing hardware devices such as the hard disk, and handling interrupts, in this protected kernel space. In contrast, application programs like browsers, word processors, or audio or video players use a separate area of memory, user space.
