The AMD graphics driver is reputedly the biggest that mainstream Linux users will encounter, approaching six million lines of code.

That does seem a bit ... excessive.

A decent chunk of that is autogenerated code

Do they know what it does?

"Register bit twiddling." Setting all the modes that all their various cards can operate in, with the associated code for sending the bit updates over the connection bus. Tedious stuff that's very prone to copy-paste errors if written by hand.

At some point you have to take AMDs word for it that these codes = this functionality, but if the right graphics come out then it can't be so wrong.
