== Educational hardware models
We have added and interacted with a few educational hardware models in QEMU.
This is useful to learn:
* how to create new hardware models for QEMU. Overview: https://stackoverflow.com/questions/28315265/how-to-add-a-new-device-in-qemu-source-code
* how the Linux kernel interacts with hardware
To get started, have a look at the "Hardware device drivers" secion under link:kernel_module/README.adoc[], and try to run those modules, and then grep the QEMU source code.
