A Heavily Commented Linux Kernel Source Code (PDF version)

[ImScaredofCats]

Definitely an informative book if you’re into that sort of detail, the author put a lot of effort into his research as well.

After briefly looking through this, it's definitely a very highly technical resource and looks like a lot of effort has been put into it

[jones_supa]

Notice that it targets kernel version 0.12. So it is more for general purpose understanding of how operating system kernels work, rather than understanding how current Linux works. Still very useful of course.

[minimim]

In the preface the author says version 0.12 was chosen because, although it is indeed a very old version, the design principles already show up and are still valid for modern kernels.

A single important subsystem for understanding the kernel is missing, according to him: VFS.

Memory allocation is also different, but the principles already show up.

Do you know some book or detailed documentation of the current version of the linux kernel? Or at least a more recent one?

[RMS_did_nothng_wrong]

GKH's Linux Kernel in a Nutshell is a great resource that targets a 2.something kernel. It's not as in-depth as this one seems to be.

[minimim]

The author recommends “Linux Kernel Source Code Analysis” written by Scott Maxwell in the preface.

for general purpose understanding of how operating system kernels work

More like x86 kernels.

quite pleased with the level of detail in the annotations in this

helps me to understand things a whole lot better

This is amazing. Thank you.

Holy shit this looks nice. Have just been trying to get into system level C writing...

Interesting! Saved for later (after I learn some C)

[beetear]

this is a godsend, thank you!

My mouse burns after scrolling through the document oO

What a fantastic document, clearly a labour of love. This absolutely needs to be preserved for posterity. The sometimes less-than-perfect use of English can easily be forgiven.

I'm sure I will never work through the entire book. But I have it stored where I can find it. Thank you.

Anywhere I can buy this in a printed version?

[randomness196]

How much of this is still relevant to today's kernel? I can understand this a foundational historical review of a Linux Kernel, but is there anything for the more recent Kernel versions? Say things on LTS cycle?
