Dependencies

• Mosquitto (https://mosquitto.org/), which is not provided by this repository
• Run time dependencies, which can be looked up in the respective directories of the simulators and genode
• Libboost (vers. 1.58 or higher)
• Protobuf (library and compiler in vers. 3)

Build instructions

• The repository consists of multiple submodules, which first need to be fetched via git submodule update --init.

Speed-dreams 2

In simulators/speed-dreams execute the following commands:

mkdir -p build
cd build
cmake ../ -DCMAKE_CXX_FLAGS=-fpermissive -DOPTION_PARKING=ON
make

SA/VM

cd genode/repos
ln -s ../../tools/genode-world world    # link the genode-world repository into the genode file structure
cd ../../
make jenkins_build_dir                  # creates a build directory, use the Makefile to configure different platforms, etc.
make toolchain                          # prepares the 16.08 toolchain of genode, used for the compilation process
make ports                              # prepares necessary library ports for genode
make vde                                # starts up a vde_switch and tap device

# Please make sure you have isohybrid installed, which is part of the syslinux-utils (Ubuntu)

ECU

• Please follow the instructions in SA/VM, but it's only necessary to do this process once (so don't redo it if you already did all the step in SA/VM).

Configuration

• One can adapt the address and port SD2 listens on for the QEMU SA/VM connection in simulations/speed-dreams/src/drivers/human/human.cpp
• For the SA/VM and ECU, one can adapt the configuration by using the *.run files in the respective directories

Run instructions

• Start a mosquitto server
• Start speed-dreams 2 by executing ./simulators/speed-dreams/build/games/speed-dreams-2
• Configure a race in speed-dreams to consist of 3 usr bots and 1 human player (use the espie track) and start it
• Start up the QEMU SA/VM by executing make -C build/genode-foc_x86_64/ run/savm (it will connect to speed-dreams)
• Start up the QEMU ECU by executing make -C build/genode-foc_x86_64/ run/ecu

Execute parking scenario

• In speed-dreams: press the 'enter' key and reduce the simulation time to 0.25 by pressing the '-' key two times (this may be unnecessary, depending on your configuration - if you're unsure, just use 0.25 and slowly increase the simulation speed with the '+' key until it becomes unresponsive)
• Use the provided mosquitto_pub by mosquitto to publish the go command: ./mosquitto_pub -h <ip-address> -p <port> -t state -m 'go; 1'
• The bot will now autonomously park, the controls will be reactivated once the car is done parking
• To abort the parking manoeuver, just publish go with value 0: ./mosquitto_pub -h <ip-address> -p <port> -t state -m 'go; 0'
