Automotive Grade Linux All Member Meeting Summer 2024

The AGL Demo recently shown at Embedded World 2024 combines a number of impressive features across its instrument cluster and infotainment systems, giving a hands-on demonstration of the technological maturity of the AGL software stack. However, while a variety of systems can be accessed and configured, any settings applied by the user (such as radio station and volume) are lost upon shutdown. By adding persistent storage to the demo, user profiles storing information from previous sessions can be created. We have implemented a grpc API written in Rust using tonic that enables persistent storage of key-value pairs in an embedded RocksDB database. The API is designed both to enhance the user experience of the AGL demo as well as to facilitate future development of new features that rely on persistent storage, such as vehicle diagnostics.
