Because of that I would recommend either using some simple and well known devices (ignoring existing implementation of their drivers in the kernel) like I²C/SPI devices that are usually used with microcontrollers. So, you could develop a C# "driver" (user-mode application really), which is then called/invoked by a C++ kernel-mode driver. It covers topics such as header files and libraries required to build drivers, various options supported by the build process, test-signing, cross Comprehensive beginner's guide to kernel development: Dive into core concepts, hands-on tutorials, and best practices. The kernel developers use a loosely time-based release process, with a new major kernel release happening every two or three months. I have come across multiple such user-run initiatives to support HOWTO do Linux kernel development “Go write a Linux driver for this device. net link. 4 kernel. You’ll be able to see the virtual disk in File Explorer and perform operations in it such as As a fellow Linux enthusiast, I know how exciting yet daunting diving into kernel driver development can be. In this instructor-led course you’ll learn how Linux is architected, the basic methods for developing on the kernel, and how to efficiently work with the Linux developer community.
