Virtual Interfaces on Arm Fixed Virtual Platforms (FVPs)

The Virtual Interfaces in Arm FVPs implement various CPU peripherals that allow to use external resources for stimulating the firmware application. Following interfaces are available and explained in details in corresponding sections:

The Virtual Input/Output (VIO) interface controls simple binary state I/O such as LED and switches.
The Virtual Streaming Interface (VSI) provides up to 8 channels for data streaming.
The Virtual Socket Interface (VSocket) connects the user application to BSD sockets on the Host computer for IP network connectivity.

Both VIO and VSI connect to Python and enable flexible scripting for test automation.
