Overview:
API extensions and performance improvements to the Linux operating system now enable it to serve as a platform for a range of embedded real-time applications, using fixed-priority preemptive scheduling. Powerful techniques exist for analytical verification of application timing constraints under this scheduling model. However, when the application is layered over an operating system the operating system must be included in the analysis. This paper assesses the degree to which the effects of device drivers in Linux can now be modeled adequately to admit fixed-priority preemptive schedulability analysis, and what remains to be done to reach that goal.
