Linux Kernel

This section explores Linux kernel mechanisms through focused implementations, source-code study and observable experiments.

The first planned series is the Raspberry Pi 4 Kernel Mechanism Lab.

Subsections of Linux Kernel

Raspberry Pi 4 Kernel Mechanism Lab

The Raspberry Pi 4 Kernel Mechanism Lab demonstrates important Linux kernel concepts using real hardware.

Planned topics include:

  • procfs interfaces

  • Workqueues

  • Delayed work

  • Tasklets and softirqs

  • Kernel timers

  • High-resolution timers

  • Kernel threads

  • Completions

  • Wait queues

  • Character devices

  • Polling

  • sysfs

  • Threaded interrupts

Detailed tutorials will be added progressively.

Linux Kernel Trimming

This series will explore how a general-purpose Linux kernel can be systematically reduced while preserving a carefully selected set of capabilities.

The experiments will cover kernel configuration, dependency analysis, source-level pruning, build validation, boot testing and real-hardware verification.
