Linux Device Driver Training

Linux Device Driver Development Course

Overall objective of this class is to teach attendees on how to develop device drivers for Linux.

This three day course provides substantial practice with the key steps in developing Linux device drivers. The course shows attendees how device drivers work with the Linux kernel, how to compile and load drivers, how to debug drivers, as well as other essential topics.

This course acquaints developers with the issues essential for Linux device driver development. The course progresses through a number of topics. Each topic is presented along with a supporting laboratory exercise before moving on to the next topic.

Attendees will spend approximately 50 percent of the class time actually gaining hands-on experience with these topics.

The following modules will be covered during the class:

Devices in Linux Devices treated as files, the /dev directory Device classes – character, block, network, pipe Creating device files with mknod User Space Driver APIs Low-level API Streams API How Loadable Modules Work Benefits of loadable modules Correct use of insmod, modprobe, rmmod, and lsmod Passing parameters to a loadable module The GPL and your driver code Compiling, Loading And Exporting Writing a simple module Compiling modules Loading/unloading modules Exporting symbols from a loadable module Creating stacked loadable modules Character Devices Major and minor numbers Registering character device file Driver methods – the file operations table Transferring data to/from User Space Tracing and Debugging printk for debugging Device information in /proc strace to track system calls ksyms and ksymoops Debuggers – gdb and kgdb Blocking and Wait Queues Multi-tasking Schedule() Wait Queues Save sleeping Poll() Accessing Hardware I/O ports vs. memory mapping Allocating and mapping I/O space Functions for reading and writing I/O ports Barriers Accessing I/O from User Space Handling Interrupts Interrupt Handler functions Restrictions of kernel code running in interrupt context Deferred interrupt handling tasklets and workqueues Accessing PCI hardware detecting PCI devices Resource conflicts Vendor/device IDs I/O mapping USB Drivers USB structure and Topology Endpoints, interfaces and configurations USB Request Blocks(urbs) Driver Structure and organization “Gadget” drivers Managing Time Timer interrupts and jiffies Short Delays Task queues Kernel Timers
Block Device Drivers	Block Device Drivers Header files Registering block drivers The block_device_operations structure Special Methods
Network Drivers	The net_device structure Sockets Naming scheme and registration Network driver methods NAPI the new API
Adding a Driver to the Kernel Tree

Where to put it – kernel layout for drivers
Modifying the Makefile
Adding it to configuration options – the Kconfig file

Course Objectives:

• To provide an understanding of the essentials of Linux device drivers.
• To give you practical experience in developing Linux device drivers.
• The steps necessary to add devices to a Linux system
• How to determine what hardware is present on a Linux system
• The purpose and functionality of device drivers
• Compiling and linking device drivers
• Trade-offs between loadable modules and drivers compiled into the kernel.

Who Should Attend:
The course is designed for software engineers who are new to Linux device drivers. Attendees should have experience with C, be able to perform basic Unix commands, and have some experience with the basic Gnu tools of gcc, gdb, and make.

Course Materials
The class materials for this course have been meticlously designed by leading practioners in this area. The workshop materials include a comprehensive student workbook and CD. The workbook contains all of the slides used in the course as well as hands-on lab exercises.  The CD contains the lab exercise code as well as a large amount of Linux software.

Course Workshop and Set-up:
The workshop makes use of standard PC’s with a desktop Linux distribution for development. The course will make use of PC’s and PC devices as examples.
