Skeletons (Templates) to programming Linux device drivers.
Suitable for cross-compiling for embedded devices and/or native-compiling for the host-pc, depending on the environment variables CROSS_COMPILE, ARCH and KERNEL_SRC_DIR. If these environment variables are not set so the modules becomes compiles for the host-pc.
Directory ./char_driver contains a C- source file and the corresponding makefile as template for programming Linux- character- device- drivers for single or multiple instances (depending on macro MAX_INSTANCES).
Directory ./select_poll contains a example how a kernel-space-driver cooperates by the user-space function "select()" respectively "poll()".
A few words about my coding style.
Yes, I know my code is not Linux-style. For example, I open curly braces in a new line, and don't use tabs except in makefiles. So the code can never officially become part of the Linux kernel, which I never planned to do. However, since I am the only author of the code so far and have maintained it alone so far, I keep the code in a form that is most pleasing to my eyes. I ask you to respect that as well, I respecting the coding style of others as well. E.g.: https://github.com/UlrichBecker/EDT-Polytouch-linux-driver
There is a saying in Germany that means: "Einem geschenkten Gaul schaut man nicht ins Maul." ("You don't look a gift horse in the mouth.")
