I am very interested in I/O flexpages and a working clans & chiefs concept to be able to improve the Perseus secure operating system project. ( http://www.krypt.cs.uni-sb.de/~perseus). And I have some students here which are interested in practical jobs. But of course they are more interested in security than in operating systems. Do you think that it would be possible to implement this features at the time of a software practical (about 6 month 6 h/week)?
We have a student looking at I/O flexpages in L4Ka/Hazelnut/x86. Tiny parts of the implementation were done by me earlier this year mostly as debugging aids. There are a few things that come with CPL>IOPL that make the implementation a bit more interesting (thinking of CLI/STI and friends).
