The two drivers are compared below. The advantages of the first method (corresponding to the disadvantages of the second method) include:● The idea is straightforward and you don't need to take the time to understand the complex I2C subsystem operati

Citation: We know that every character device has a CDEV structure in the kernel that describes it, and one of the more important members of this structure isConst struct file_operations *ops;The function of this structure is to match the system call in the user program with the specific implementation function one by one in the driver. When invoking a system call to a character device file in a user program, you know which specific function to invoke
