Hi All,
Are there any papers or documentation talking about response time in Fiasco? I think this is an important aspect in Fiasco as it is designed for real time.
To the best of my knowledge, seL4 (http://sel4.systems/) is the only protected-mode real-time OS with a complete and sound WCET analysis, see - http://www.ssrg.nicta.com.au/publications/papers/Blackham_SCRH_11.abstract - http://www.ssrg.nicta.com.au/publications/papers/Blackham_SH_12.abstract
All other systems that claim suitability for hard RT use an unsound empirical approach (i.e. put a high load on the system, measure response time, add a fudge factor).
