To add what Vasily already said, L4Linux has a decent performance but cannot cope with what hardware features can achieve, esp. for the memory and CPU virtualization. For I/O there isn't really an architectural difference, except again if there's hardware support, such as interrupt injection. For L4Linux there's the (famous) paper from 1997 describing it in its first variant: https://os.inf.tu-dresden.de/papers_ps/sosp97.pdf Adam _______________________________________________ l4-hackers mailing list l4-hackers@os.inf.tu-dresden.de http://os.inf.tu-dresden.de/mailman/listinfo/l4-hackers
