Yocto Tutorial - 31 Kernel Development | Device Driver Integration in Mainline Kernel (Part 2)
In this second part Device Driver Integration, we'll guide you through the crucial steps needed to prepare for seamless driver integration into the mainline Linux kernel. Here's what we'll cover:
1) Get Kernel Source: We'll show you how to obtain the kernel source, a fundamental starting point for custom driver integration.
2) Git repo Initialization: Learn how to initialize a Git repository for your project, a crucial step in tracking changes and managing your code.
3) Find drivers folder: We'll navigate the kernel source to locate the "drivers" folder, where device drivers reside.
4) Find Relevant Parent Driver Folder: Discover how to identify the appropriate parent driver folder for your specific driver, ensuring a logical and organized structure.
5) Create Our Driver Folder: We'll walk you through the process of creating your custom driver folder within the selected parent directory.
6) Create Kconfig and Makefile: Understand the importance of Kconfig and Makefiles in driver development and how to create them for your driver.
7) Make Entries in Kconfig and Makefile: Learn how to make the necessary entries in Kconfig and Makefiles to configure your driver.
8) Create or Copy Sources: Explore how to populate your driver folder with the required source code, whether by creating it from scratch or copying existing code.
9) Make Kconfig and Makefile Entry in Parent Driver: We'll guide you on the steps to make Kconfig and Makefile entries within the parent driver, ensuring seamless integration.
