Linux Kernel Internals
🧠From Embedded Developer to Embedded Linux Architect Roadmap
Every week, I receive messages that sound something like this: “How do I become an Embedded Developer?”“Where should I start
Introduction to Linux Device Drivers
If you’ve ever wondered how your applications talk to hardware in Linux — welcome to the fascinating world of Linux
Writing a Simple Linux Kernel Module
In the Linux kernel, drivers can be integrated in two different ways.One option is to compile the driver as part
🧩 Tasklets in Linux Device Drivers
Continuing our exploration of Linux interrupt handling, this article dives into Tasklets, a lightweight bottom-half mechanism built on SoftIRQs. Learn how Tasklets work, where they’re used, and explore a simple driver example.
Bottom Halves in Linux Device Drivers
After exploring Interrupt Management in our previous post, let’s dive deeper into the world of Bottom Halves in Linux Device Drivers — uncover their types, use cases, and learn how Workqueues, Tasklets, and Threaded IRQs keep Linux drivers fast, efficient, and beautifully designed.
Linux Interrupt Handling: Top Half & Bottom Half
Ever wondered how Linux stays so responsive — even when hundreds of devices are fighting for the CPU’s attention? When
