How to write a driver in linux?

Question

System administration

I dug around in the net, I realized that drivers are like linux kernel modules. And this was followed by advice on adding the source code to folders to recompile the entire system! (The meaning is clear!) But isn't there a simpler mechanism?

Answer 2

The Linux driver can be compiled as a kernel module and connected online using the modprobe command.
the lsmod command will show how many "module" drivers are installed on the system.
it is quite possible to distribute kernel modules in a separate package (and in your own repository) and install them into the system as needed. see virtualbox kernel modules for an example.
