How is a kernel written?

The kernel is written mostly in C, with some architecture-dependent parts written in assembly. A good understanding of C is required for kernel development. Assembly (any architecture) is not required unless you plan to do low-level development for that architecture.

How can I learn kernel?

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.

In this article, I’ll provide a quick checklist of steps involved with making your first kernel contribution, and look at what you should know before submitting a patch.

Is it hard to become a Linux kernel developer?

The learning curve to becoming a Linux kernel developer is pretty steep and choosing the right direction might be somewhat difficult (but not as hard as you think – see my previous article .) However, I have some ideas on how to start this beautiful journey.

What’s the next step in the Linux kernel?

The next step, after improving the style, is to actually fix the broken code. The Linux kernel build system uses the sparse static code analyzer which, when enabled, runs over every file that is compiled and if there is anything wrong with it, reports it. It’s as simple as that.>

Who are the drivers for the Linux kernel?

So basically the drivers/staging area is a home for not yet officially supported drivers. The whole area is supported by Greg KH, the Linux Driver Project is behind it and people involved communicate on the driverdev-devel mailing list.
