Building Kernel Modules In-Tree During Kernel Compilation

Kernel modules are usually built out-of-tree, but for modules tightly coupled with kernel internals it's better to build them in-tree, as part of the kernel compilation itself, for header and config compatibility and automatic compilation during make . The example below uses linux-5.10/ as the so

Implement an IRQ Interrupt Handler in a Linux Kernel Driver (Full Guide)

Interrupts are vital for real-time responsiveness in Linux kernel modules. Whether you’re writing drivers for GPIOs, network … Read more

Create a Custom BSP Layer in Yocto Using yocto-bsp

In the Yocto Project, a Board Support Package (BSP) layer contains hardware-specific configurations, kernel recipes, device trees, and bootloader definitions for a target board. The yocto-bsp command-line script provides an interactive wizard to generate a clean BSP layer skeleton conforming to Yo
