Supporting nested resources in MrsP

The original MrsP protocol proposal presented a new multiprocessor resource sharing protocol based on the prop- erties and behaviour of the Priority Ceiling Protocol, supported by a novel helping mechanism. While this approach proved to be as simple and elegant as the single processor protocol, the implications with regard to nested-resources analysis under multiprocessor systems was identified as improvable by both MrsP authors and academic community. In this on-going work we propose a complete approach to nested resources behaviour and analysis under the MrsP protocol.
