In this video, we implement a Linux character device driver with the most common file operations: open, release, read, and write.
We create a device buffer, protect it using a mutex, and demonstrate how data is written from user space and read back from the kernel.
Finally, we test the driver using standard shell commands and analyze the kernel logs with dmesg.
