At the recent Embedded Linux Conference in Portland, National Instruments software engineer Julia Cartwright, an acting maintainer on a stable release of the RT patch, gave a well-attended presentation called “What Every Driver Developer Should Know about RT.” Cartwright started with an overview of RT, which helps provide guarantees for user task execution for embedded applications that require a high level of determinism. She then described the classes of driver-related problems that can have a detrimental impact to RT, as well as potential resolutions.
