Drivers for Special Hardware Parts

User space I/O drivers (UIO) can be implemented through the real-time capable
kernel. This enables a memory mapping functionality to be accessed directly from
the user space. In this manner, you can access the process image of the connected
I/O modules as well as other hardware areas.
