Using complete system simulation for temporal debugging of general purpose operating systems and workloads

摘要: Digital convergence is precipitating the addition of soft real-time applications to mainstream desktop and server operating environments. Most traditional debuggers for systems lack a notion temporal correctness, making them unsuitable system design analysis. We propose leveraging complete simulation build debugger which capable analyzing mixed real-world workloads. Traditional based on utilize slow, but accurate, simulators. Complete simulators accept an approximate model time in exchange higher performance. The performance allows these analyze high-end commercial applications. describe report some early experiences simple workload. tool offers non-intrusive, predictable environment debugging complex workloads with partial constraints. simulator foundation interactive time-critical sequences while preserving execution flow.
