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](https://github.com/0xAX/linux-insides/blob/master/SUMMARY.md). ## Chapter status (kernel v7.2.0) > [!IMPORTANT] > I 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. - [x] 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](https://en.wikipedia.org/wiki/Assembly_language) - Proficiency with the [C programming language](https://en.wikipedia.org/wiki/C_(programming_language)) - Additionally, you can find lots of useful information about x86_64 processors in [Intel Software Developer Manuals](https://www.intel.com/content/www/us/en/developer/articles/technical/intel-sdm.html) > [!TIP] > You can get started with Assembler with my other series of posts about the [Assembly programming](https://github.com/0xAX/asm). ## Translations Thanks to the volunteers, the posts about Linux are translated into different languages. > [!NOTE] > The translations may diverge from the original content. * [Brazilian Portuguese](https://github.com/mauri870/linux-insides) * [Chinese](https://github.com/hust-open-atom-club/linux-insides-zh) * [Japanese](https://github.com/tkmru/linux-insides-ja) * [Korean](https://github.com/junsooo/linux-insides-ko) * [Russian](https://github.com/proninyaroslav/linux-insides-ru) * [Spanish](https://github.com/leolas95/linux-insides) * [Turkish](https://github.com/ayyucedemirbas/linux-insides_Turkish) ## Contribution Read the [Contribution guide](./CONTRIBUTING.md) to learn how to contribute to the project.
