In this paper, we address the problem of adaptively reserving the CPU to concurrent soft real-time tasks, in order to meet target Quality of Service requirements. First, we present two new techniques inspired to the idea of stochastic control. Then, we present a flexible and modular software architecture suitable for adaptive scheduling, realised as a minimally invasive set of modifications to the Linux Kernel. Finally, we show experimental results that validate our approach and prove its effectiveness in the context of multimedia applications.
