A Swap Dataspace Manager for DROPS

The swappable dataspace manager (DMSwap) is an attempt to further
develop the virtual-memory management system of DROPS. With the porting
of the Linux-IDE drivers to DROPS, the possibility arose to implement a
pager that provides a replacement policy and is able to move
physical memory pages to a hard disk.
This talk will deal with the chosen replacement policy, as well as the
pager's design goals. A brief introduction to the virtual-memory concept
of L4 will be given, and some (necessary) performance improvements will
be discussed.
