/dev/one

A device that when read from, returns '1' in ascii, this is a learning project - don't take this code as an example :)

Building

Running make should work for your system, if not, try installing linux-headers using your distributions package manager.

make

To load the module after building, do

sudo insmod src/dev_one.ko

After this, you can read from /dev/one !

sudo head -c 20 /dev/one
