Write a real, working Linux driver
Will be taught by Greg K-H
This tutorial will teach the you how to write a working Linux kernel driver for a real device. You will be given a device apon the start of the class, and by the end, will have created a kernel driver that controls the device that will be acceptable for inclusion in the main Linux kernel tree.
The device is a USB thermometer and will cost a small amount (2007 price: $30) if you wish to keep the device.
Topics that will be covered:
- understanding the kernel build process
- understanding the module load process
- the basics of the kernel driver and device model that are needed for all driver authors.
- how to interact with a kernel driver from userspace.
- understanding the essay writing on how to talk to the hardware.
- proper kernel coding guidelines essay.
Skills necessary for this tutorial:
- You must know how to build, install, and run, a standard kernel.org kernel .
.
- Intermediate understanding and knowledge of the C language.
- You must have a laptop with a working USB connection, running the latest version of the 2.6 kernel from kernel.org.
Items to check to help get the most out of this tutorial:
- Plug in a USB thumb drive, printer, or digital camera to test that your userspace USB utilities are working.
- Remove a kernel module (with modprobe -r or rmmod) to make sure that your kernel is built with module unloading turned on.
