Hi, i want to evaluate l4. The first problem i have is to chose the 'right' l4 version. * There is a Dresden version "l4 v2" There is a Karlsruhe version "l4 x.2" * L4Linux is available from Dresden als 2.2.x L4Linux is available from Karlsruhe als 2.4.x Both seems to run on both l4 ipc protocolversion. * At Dresden they have basic parts of os specific components, called DROPS. Also a implementation of an windowmanager (DOpE). At Karlsruhe i don't see any additional os specific components at all. * The L4Ka seems to be the base for ports to other hardwareplatforms, like PowerPC, MIPS etc developed at UNSW. My problem is, to understand the difference/commons in - priority of development of this parts on Dresden and Karlsruhe. - collaboration between Dresden, Karlsruhe and UNSW. If a newbie like want to start, which is the 'right' l4 version and why is it the 'right' version. Frank. -- Frank Matthieß [x] Nail here for new monitor.
