CHAPTER 14 Chapter 14 The Linux Device Model One of the stated goals for the development cycle was the creation of a unified device model for the kernel. Device drivers take on a special role in the Linux kernel. They are distinct “black boxes” that make a particular piece of hardware respond to a well-defined internal programming interface; they hide completely the details of how the device works.

The Linux device driver architecture is documented well by the freely available publication authored by Rubini et al Rubini et al, The device model core defines a set of structures and functions. The structures form the building blocks of the device model and the functions update and maintain the device model. The dmesg command shows all device drivers recognized by the kernel: $ dmesg. Or with grep: $ dmesg | grep SOME_DRIVER_KEYWORD. Any driver that's recognized will show in the results. If nothing is recognized by the dmesg or lscpi commands, try these two commands to see if the driver is at least loaded on the disk: $ / sbin / lsmod. and $ find / lib / modules.
