Adding a new module in the Kernel source

Adding a new module in the Kernel source

[beware]

Hi everybody,

I want to compile the last stable version of the Linux Kernel
(2.6.15.6) but i want to add my own module in the kernel.

Firstly, is it a good idea to do this? Or it's more simple to add this
module after the compilation and add it to the modules which are
automicaly laoded?

But, if i want to add this module in the kernel source, what do i have
to do for this operation?

Thank you.

PS : sorry for my not fluent english.

To include the module in kernel sources is simple.
Let's assume it is a char driver and the module is named beware.

1) copy source to drivers/char
cp beware.c $KERNEL_SRC_DIR/drivers/char/

2) Edit makefile to include your module:
Just above the clean-files statement add:
obj-y += beware.o

And you are ready to compile the kernel with your module built-in.

May I also refer you to Linux Device Drivers volume 3 (LDD3) and to
Documentation/kbuild/* in the kernel source.
