On a high level, nowadays features of both Fiasco and L4Re as a whole
are mostly driven by project and customer requirements, including
support for new architectures and specific features. The recently added
support for MIPS is one such example and coverage for MIPS will be
further increased. There is more in the pipe and work goes on however I
cannot share all of this yet. The aim definitely is to have additions
covered under open source.
There are also thing happening in research and development labs, people
using the system or parts of it in various, and interesting, ways, or
are extending it. However, getting the interesting bits contributed and
then even integrating them is challenging as it requires significant
resources on both sides or at least on our side. So if interests are
big enough things tend to happen :)
