This blog series creates a small operating system in the 自由之门手机版32. Each post is a small tutorial and includes all needed code, so you can follow along if you like. The source code is also available in the corresponding Github repository.

CPU exceptions occur in various erroneous situations, for example when accessing an invalid memory address or when dividing by zero. To react to them we have to set up an interrupt descriptor table that provides handler functions. At the end of this post, our kernel will be able to catch breakpoint exceptions and to resume normal execution afterwards.

This post explores the double fault exception in detail, which occurs when the CPU fails to invoke an exception handler. By handling this exception we avoid fatal triple faults that cause a system reset. To prevent triple faults in all cases we also set up an 自由之门手机版32 to catch double faults on a separate kernel stack.

In this post we set up the programmable interrupt controller to correctly forward hardware interrupts to the CPU. To handle these interrupts we add new entries to our interrupt descriptor table, just like we did for our exception handlers. We will learn how to get periodic timer interrupts and how to get input from the keyboard.

This post introduces paging, a very common memory management scheme that we will also use for our operating system. It explains why memory isolation is needed, how segmentation works, what virtual memory is, and how paging solves memory fragmentation issues. It also explores the layout of multilevel page tables on the x86_64 architecture.

This post shows how to implement paging support in our kernel. It first explores different techniques to make the physical page table frames accessible to the kernel and discusses their respective advantages and drawbacks. It then implements an address translation function and a function to create a new mapping.

This post adds support for heap allocation to our kernel. First, it gives an introduction to dynamic memory and shows how the borrow checker prevents common allocation errors. It then implements the basic allocation interface of Rust, creates a heap memory region, and sets up an allocator crate. At the end of this post all the allocation and collection types of the built-in alloc crate will be available to our kernel.

In this post we explore cooperative multitasking and the async/await feature of Rust. We take a detailed look how async/await works in Rust, including the design of the 自由之门翻墙最新手机版 trait, the state machine transformation, and pinning. We then add basic support for async/await to our kernel by creating an asynchronous keyboard task and a basic executor.

First Edition
You are currently viewing the second edition of “Writing an OS in Rust”. The first edition is very different in many aspects, for example it builds upon the GRUB bootloader instead of using the `bootloader` crate. In case you're interested in it, it is still available. Note that the first edition is no longer updated and might contain outdated information. read the first edition »

Creating and maintaining this blog and the associated libraries is a lot of work, but I really enjoy doing it. By supporting me, you allow me to invest more time in new content, new features, and continuous maintenance.
The best way to support me is to sponsor me on GitHub. GitHub will even match sponsorships until October 2024! If you prefer other platforms, I also have 自由之门翻墙最新手机版 and Donorbox accounts. The latter is the most flexible as it supports multiple currencies and one-time contributions.
