I believe this book on the subject may be what you are looking for: http://www.amazon.co.uk/Linux-Device-Dr. ce+drivers. device driver authors need to know how to work with many of the kernel's sub- systems. It thus makes a good introduction to kernel programming in general. Linux is still a work in progr ess, and there's always a place for new programmers to jump into the game. If, on the other hand, you are just trying to write a device driver. Internally Linux kernel implements the TCP/IP protocol stack . It is possible to divide the networking code into parts - one which implements the actual protocols (the /usr/linux/net/ipv4 directory) and the other which implements device driver various network hardware.(/usr/src/linux/drivers/net ). The kernel code for TCP/IP is. Tutorials. Example: Reference Counting in Linux Device Drivers. Microsoft's SLAM toolkit has been successfully used to find bugs in Windows device drivers. SLAM automatically verifies device driver whether a device driver adheres to a set of specifications. SLAM provides a test harness for device drivers that calls the. This article explains the creation process of a Linux kernel device driver for an undocumented USB device. After having reverse-engineered the USB communication protocol, I present the architecture of the USB device driver. In addition to the kernel driver I introduce a simple user-space tool that can be. Android HAL implementation looks similar to a Linux device driver. (Since LDD is a HAL for Linux); Most of the Vendor specific implementations can be done in Android HAL rather than the driver. So that license difference between the driver (Open source license GPL) and the HAL (Apache License) will. But running the wheezy Linux it also is a complete Linux embedded system running on an ARM platform. That makes it quite interesting for programming and brought me to the idea to implement an I/O device driver on it, just to set on and off a digital output and to read the state of a input. To build a device.
