Does Linux use device drivers?
Linux provides kernel memory allocation and deallocation routines and it is these that the device drivers use. Kernel memory is allocated in chunks that are powers of 2. For example 128 or 512 bytes, even if the device driver asks for less.
How do I start device driver development?
- Step 1: Know about the Hardware.
- Step 2: Say Hello to your hardware (In other words, talk to your hardware)
- Step 3: Initialize your hardware.
- Step 4: Control your hardware.
- Step 5: Data Communication to your hardware.
- Step 6: Start and Stop data communication.
- Step 7: Fine-Tune and Debug Your Driver based on Testing.
What is Register_chrdev?
register_chrdev(major, name, fops); stores the given name (a string) and fops (a struct file_operations *) in the entry of the array chrdevs[] indexed by the integer major , the major device number of the device.

What are Linux drivers?
Drivers are used to help the hardware devices interact with the operating system. In Linux, even the hardware devices are treated like ordinary files, which makes it easier for the software to interact with the device drivers. When a device is connected to the system, a device file is created in /dev directory.
What device may not need drivers?
