I feel compelled to write this, on my Android F1

The kernel isn't just a forward tool for communicating with to hardware to
a hacker, but a method of implementing an algorithm or fancy code or a
particular hack to the hardware through software, especially to the freebsd
hacker.

Example, a sound card has been reversed engineered to work with freebsd,
instead of your basic functions you can interact with various userland
applications, do messaging functions, or even make things parallel, example
is amplify to 5.1 using outside libraries or a hack

The kernel is a design to keep hardware happy, if you have coding ability
and like making full usage of it, find old drivers and improve them and add
your craft to the project

I'll write more as I research freebsds kernel
