What's really cool is this hands-on Rust book takes you inside the Linux kernel and gives you the power to reshape it. It's all about building working kernel subsystems from scratch, covering process management, memory allocation, virtual file systems, networking, device drivers, inter-process communication, and AI-powered inference, and all in Rust. When you're done, you'll have registered procfs and sysfs interfaces, written Netfilter hooks that classify packets with a neural network, constructed RAII wrappers for DMA buffers and interrupt handlers, and implemented a complete in-memory file system on the VFS layer.
Each chapter adds new source files to the same module, so by the time you get to the last chapter, your codebase has grown to various kernel subsystems. This hands-on, trainer-led approach is designed for both those new to Rust and experienced Rust developers looking to get into kernel space. You'll get the skills, patterns and confidence to write top-notch kernel code that's just as fast and safe as its C equivalent.
