Introduction
linux-insides is a book-in-progress about the Linux kernel and its insides. The goal of this project is simple - to share knowledge about the Linux kernel internals and related low-level topics. If you're curious about what's under the hood, see the Table of Contents.
Chapter status (kernel v7.2.0)
ImportantI started writing this series when the latest version of the kernel was 3.18. A lot has changed since then, and I am in progress of updating the content to reflect modern kernels (v6.18+). I'll continue revising the posts as the kernel evolves.
Booting (updated for v7.2.0)
Initialization (pending v6.18.0 review)
Interrupts (pending v6.18.0 review)
System calls (pending v6.18.0 review)
Timers and time management (pending v6.18.0 review)
Synchronization primitives (pending v6.18.0 review)
Memory management (pending v6.18.0 review)
Cgroups (pending v6.18.0 review)
SMP (pending v6.18.0 review)
Kernel mechanisms (pending v6.18.0 review)
Data Structures in the Linux Kernel (pending v6.18.0 review)
x86 fundamentals (pending v6.18.0 review)
Toolchain and binaries (pending v6.18.0 review)
Initial ram disk (pending v6.18.0 review)
Contributing to the Linux kernel (pending v6.18.0 review)
Requirements
Prior knowledge about the Assembly language
Proficiency with the C programming language
Additionally, you can find lots of useful information about x86_64 processors in Intel Software Developer Manuals
TipYou can get started with Assembler with my other series of posts about the Assembly programming.
Translations
Thanks to the volunteers, the posts about Linux are translated into different languages.

The word you're looking for is "pseudonymous", which is a very, very, very different thing.

2 points · Open discussionThere is a great deal more information about how sycalls are implemented on Linux in this excellent free GitHub book called linux-insides:
https://github.com/0xAX/linux-insides/tree/master/SysCall
I can highly recommend it to anyone who wants to learn more about the kernel. This book is particularly great because it does not assume any kernel programming background knowledge - superficial understanding of C should be enough.
In Unix SyscallsThis is very old, for a more recent version
