Device drivers are a significant source of system instability. In this paper, we make the case for running device drivers at user-level to improve robustness and resource management. We present a framework for running drivers at user-level whose goal is to provide similar performance when compared to in-kernel drivers. We also present initial promising performance results for the framework.
