%X Many tools exists for writing safe and correct device
drivers for conventional operating systems, from runtime
driver management layers (that try to detect errors and
recover from them) to static analysis systems like
SLAM. Unfortunately, these tools do not map well to the
concurrent drivers we write for RMoX. This presentation
will look at how we can build safe and correct device
drivers, using traditional occam analysis approaches (such
as CSP) and tools (such as FDR). Experiments in generating
formal models of hardware/driver interfaces from our
occam implementations will be described, along with how we
intend to use these models to prove correctness properties
for our drivers.
