Driver Initialization Sequence

Drivers must register themselves with the kernel

register_chrdev(), register_blkdev(), register_netdev(), etc.

For block and character drivers you’ll need to assign major/minor numbers

Can be done statically or dynamically

Coordinate with <linux>/Documentation/devices.txt

You’ll need to create device nodes as well

Statically or via UDEV
